-           line="21">A #GESAsset in the GStreamer Editing Services represents a resources
-that can be used. In particular, any class that implements the
-#GESExtractable interface may have some associated assets with a
-corresponding #GESAsset:extractable-type, from which its objects can be
-extracted using ges_asset_extract(). Some examples would be
-#GESClip, #GESFormatter and #GESTrackElement.
-
-All assets that are created within GES are stored in a cache; one per
-each #GESAsset:id and #GESAsset:extractable-type pair. These assets can
-be fetched, and initialized if they do not yet exist in the cache,
-using ges_asset_request().
-
-``` c
-GESAsset *effect_asset;
-GESEffect *effect;
-
-// You create an asset for an effect
-effect_asset = ges_asset_request (GES_TYPE_EFFECT, "agingtv", NULL);
-
-// And now you can extract an instance of GESEffect from that asset
-effect = GES_EFFECT (ges_asset_extract (effect_asset));
-
-```
-
-The advantage of using assets, rather than simply creating the object
-directly, is that the currently loaded resources can be listed with
-ges_list_assets() and displayed to an end user. For example, to show
-which media files have been loaded, and a standard list of effects. In
-fact, the GES library already creates assets for #GESTransitionClip and
-#GESFormatter, which you can use to list all the available transition
-types and supported formats.
-
-The other advantage is that #GESAsset implements #GESMetaContainer, so
-metadata can be set on the asset, with some subclasses automatically
-creating this metadata on initiation.
-
-For example, to display information about the supported formats, you
-could do the following:
-|[
-   GList *formatter_assets, *tmp;
-
-   //  List all  the transitions
-   formatter_assets = ges_list_assets (GES_TYPE_FORMATTER);
-
-   // Print some infos about the formatter GESAsset
-   for (tmp = formatter_assets; tmp; tmp = tmp-&gt;next) {
-     g_print ("Name of the formatter: %s, file extension it produces: %s",
-       ges_meta_container_get_string (
-         GES_META_CONTAINER (tmp-&gt;data), GES_META_FORMATTER_NAME),
-       ges_meta_container_get_string (
-         GES_META_CONTAINER (tmp-&gt;data), GES_META_FORMATTER_EXTENSION));
-   }
-
-   g_list_free (transition_assets);
-
-]|
-
-## ID
-
-Each asset is uniquely defined in the cache by its
-#GESAsset:extractable-type and #GESAsset:id. Depending on the
-#GESAsset:extractable-type, the #GESAsset:id can be used to parametrise
-the creation of the object upon extraction. By default, a class that
-implements #GESExtractable will only have a single associated asset,
-with an #GESAsset:id set to the type name of its objects. However, this
-is overwritten by some implementations, which allow a class to have
-multiple associated assets. For example, for #GESTransitionClip the
-#GESAsset:id will be a nickname of the #GESTransitionClip:vtype. You
-should check the documentation for each extractable type to see if they
-differ from the default.
-
-Moreover, each #GESAsset:extractable-type may also associate itself
-with a specific asset subclass. In such cases, when their asset is
-requested, an asset of this subclass will be returned instead.
-
-## Managing
-
-You can use a #GESProject to easily manage the assets of a
-#GESTimeline.
-
-## Proxies
-
-Some assets can (temporarily) act as the #GESAsset:proxy of another
-asset. When the original asset is requested from the cache, the proxy
-will be returned in its place. This can be useful if, say, you want
-to substitute a #GESUriClipAsset corresponding to a high resolution
-media file with the asset of a lower resolution stand in.
-
-An asset may even have several proxies, the first of which will act as
-its default and be returned on requests, but the others will be ordered
-to take its place once it is removed. You can add a proxy to an asset,
-or set its default, using ges_asset_set_proxy(), and you can remove
-them with ges_asset_unproxy().</doc>

-it receives.
-
-## Time Effects
-
-Some operations will change the timing of the stream data they receive
-in some way. In particular, the #GstElement that they wrap could alter
-the times of the segment they receive in a #GST_EVENT_SEGMENT event,
-or the times of a seek they receive in a #GST_EVENT_SEEK event. Such
-operations would be considered time effects since they translate the
-times they receive on their source to different times at their sink,
-and vis versa. This introduces two sets of time coordinates for the
-event: (internal) sink coordinates and (internal) source coordinates,
-where segment times are translated from the sink coordinates to the
-source coordinates, and seek times are translated from the source
-coordinates to the sink coordinates.
-
-If you use such an effect in GES, you will need to inform GES of the
-properties that control the timing with
-ges_base_effect_register_time_property(), and the effect's timing
-behaviour using ges_base_effect_set_time_translation_funcs().
-
-Note that a time effect should not have its
-#GESTrackElement:has-internal-source set to %TRUE.
-
-In addition, note that GES only *fully* supports time effects whose
-mapping from the source to sink coordinates (those applied to seeks)
-obeys:
-
-+ Maps the time `0` to `0`. So initial time-shifting effects are
-  excluded.
-+ Is monotonically increasing. So reversing effects, and effects that
-  jump backwards in the stream are excluded.
-+ Can handle a reasonable #GstClockTime, relative to the project. So
-  this would exclude a time effect with an extremely large speed-up
-  that would cause the converted #GstClockTime seeks to overflow.
-+ Is 'continuously reversible'. This essentially means that for every
-  time in the sink coordinates, we can, to 'good enough' accuracy,
-  calculate the corresponding time in the source coordinates. Moreover,
-  this should correspond to how segment times are translated from
-  sink to source.
-+ Only depends on the registered time properties, rather than the
-  state of the #GstElement or the data it receives. This would exclude,
-  say, an effect that would speedup if there is more red in the image
-  it receives.
-
-Note that a constant-rate-change effect that is not extremely fast or
-slow would satisfy these conditions. For such effects, you may wish to
-use ges_effect_class_register_rate_property().</doc>

-a single layer but may control several #GESTrackElement-s that span
-several #GESTrack-s. A clip will ensure that all its children share the
-same #GESTimelineElement:start and #GESTimelineElement:duration in
-their tracks, which will match the #GESTimelineElement:start and
-#GESTimelineElement:duration of the clip itself. Therefore, changing
-the timing of the clip will change the timing of the children, and a
-change in the timing of a child will change the timing of the clip and
-subsequently all its siblings. As such, a clip can be treated as a
-singular object in its layer.
-
-For most uses of a #GESTimeline, it is often sufficient to only
-interact with #GESClip-s directly, which will take care of creating and
-organising the elements of the timeline's tracks.
-
-## Core Children
-
-In more detail, clips will usually have some *core* #GESTrackElement
-children, which are created by the clip when it is added to a layer in
-a timeline. The type and form of these core children will depend on the
-clip's subclass. You can use ges_track_element_is_core() to determine
-whether a track element is considered such a core track element. Note,
-if a core track element is part of a clip, it will always be treated as
-a core *child* of the clip. You can connect to the
-#GESContainer::child-added signal to be notified of their creation.
-
-When a child is added to a clip, the timeline will select its tracks
-using #GESTimeline::select-tracks-for-object. Note that it may be the
-case that the child will still have no set #GESTrackElement:track
-after this process. For example, if the timeline does not have a track
-of the corresponding #GESTrack:track-type. A clip can safely contain
-such children, which may have their track set later, although they will
-play no functioning role in the timeline in the meantime.
-
-If a clip may create track elements with various
-#GESTrackElement:track-type(s), such as a #GESUriClip, but you only
-want it to create a subset of these types, you should set the
-#GESClip:supported-formats of the clip to the subset of types. This
-should be done *before* adding the clip to a layer.
-
-If a clip will produce several core elements of the same
-#GESTrackElement:track-type, you should connect to the timeline's
-#GESTimeline::select-tracks-for-object signal to coordinate which
-tracks each element should land in. Note, no two core children within a
-clip can share the same #GESTrack, so you should not select the same
-track for two separate core children. Provided you stick to this rule,
-it is still safe to select several tracks for the same core child, the
-core child will be copied into the additional tracks. You can manually
-add the child to more tracks later using ges_clip_add_child_to_track().
-If you do not wish to use a core child, you can always select no track.
-
-The #GESTimelineElement:in-point of the clip will control the
-#GESTimelineElement:in-point of its core children to be the same
-value if their #GESTrackElement:has-internal-source is set to %TRUE.
-
-The #GESTimelineElement:max-duration of the clip is the minimum
-#GESTimelineElement:max-duration of its core children. If you set its
-value to anything other than its current value, this will also set the
-#GESTimelineElement:max-duration of all its core children to the same
-value if their #GESTrackElement:has-internal-source is set to %TRUE.
-As a special case, whilst a clip does not yet have any core children,
-its #GESTimelineElement:max-duration may be set to indicate what its
-value will be once they are created.
-
-## Effects
-
-Some subclasses (#GESSourceClip and #GESBaseEffectClip) may also allow
-their objects to have additional non-core #GESBaseEffect-s elements as
-children. These are additional effects that are applied to the output
-data of the core elements. They can be added to the clip using
-ges_clip_add_top_effect(), which will take care of adding the effect to
-the timeline's tracks. The new effect will be placed between the clip's
-core track elements and its other effects. As such, the newly added
-effect will be applied to any source data **before** the other existing
-effects. You can change the ordering of effects using
-ges_clip_set_top_effect_index().
-
-Tracks are selected for top effects in the same way as core children.
-If you add a top effect to a clip before it is part of a timeline, and
-later add the clip to a timeline, the track selection for the top
-effects will occur just after the track selection for the core
-children. If you add a top effect to a clip that is already part of a
-timeline, the track selection will occur immediately. Since a top
-effect must be applied on top of a core child, if you use
-#GESTimeline::select-tracks-for-object, you should ensure that the
-added effects are destined for a #GESTrack that already contains a core
-child.
-
-In addition, if the core child in the track is not
-#GESTrackElement:active, then neither can any of its effects be
-#GESTrackElement:active. Therefore, if a core child is made in-active,
-all of the additional effects in the same track will also become
-in-active. Similarly, if an effect is set to be active, then the core
-child will also become active, but other effects will be left alone.
-Finally, if an active effect is added to the track of an in-active core
-child, it will become in-active as well. Note, in contrast, setting a
-core child to be active, or an effect to be in-active will *not* change
-the other children in the same track.
-
-### Time Effects
-
-Some effects also change the timing of their data (see #GESBaseEffect
-for what counts as a time effect). Note that a #GESBaseEffectClip will
-refuse time effects, but a #GESSource will allow them.
-
-When added to a clip, time effects may adjust the timing of other
-children in the same track. Similarly, when changing the order of
-effects, making them (in)-active, setting their time property values
-or removing time effects. These can cause the #GESClip:duration-limit
-to change in value. However, if such an operation would ever cause the
-#GESTimelineElement:duration to shrink such that a clip's #GESSource is
-totally overlapped in the timeline, the operation would be prevented.
-Note that the same can happen when adding non-time effects with a
-finite #GESTimelineElement:max-duration.
-
-Therefore, when working with time effects, you should -- more so than
-usual -- not assume that setting the properties of the clip's children
-will succeed. In particular, you should use
-ges_timeline_element_set_child_property_full() when setting the time
-properties.
-
-If you wish to preserve the *internal* duration of a source in a clip
-during these time effect operations, you can do something like the
-following.
-
-```c
-void
-do_time_effect_change (GESClip * clip)
-{
-  GList *tmp, *children;
-  GESTrackElement *source;
-  GstClockTime source_outpoint;
-  GstClockTime new_end;
-  GError *error = NULL;
-
-  // choose some active source in a track to preserve the internal
-  // duration of
-  source = ges_clip_get_track_element (clip, NULL, GES_TYPE_SOURCE);
-
-  // note its current internal end time
-  source_outpoint = ges_clip_get_internal_time_from_timeline_time (
-        clip, source, GES_TIMELINE_ELEMENT_END (clip), NULL);
-
-  // handle invalid out-point
-
-  // stop the children's control sources from clamping when their
-  // out-point changes with a change in the time effects
-  children = ges_container_get_children (GES_CONTAINER (clip), FALSE);
-
-  for (tmp = children; tmp; tmp = tmp-&gt;next)
-    ges_track_element_set_auto_clamp_control_source (tmp-&gt;data, FALSE);
-
-  // add time effect, or set their children properties, or move them around
-  ...
-  // user can make sure that if a time effect changes one source, we should
-  // also change the time effect for another source. E.g. if
-  // "GstVideorate::rate" is set to 2.0, we also set "GstPitch::rate" to
-  // 2.0
-
-  // Note the duration of the clip may have already changed if the
-  // duration-limit of the clip dropped below its current value
-
-  new_end = ges_clip_get_timeline_time_from_internal_time (
-        clip, source, source_outpoint, &amp;error);
-  // handle error
-
-  if (!ges_timeline_elemnet_edit_full (GES_TIMELINE_ELEMENT (clip),
-        -1, GES_EDIT_MODE_TRIM, GES_EDGE_END, new_end, &amp;error))
-    // handle error
-
-  for (tmp = children; tmp; tmp = tmp-&gt;next)
-    ges_track_element_set_auto_clamp_control_source (tmp-&gt;data, TRUE);
-
-  g_list_free_full (children, gst_object_unref);
-  gst_object_unref (source);

-#GESTimelineElement:start of @clip at the same timeline position. If
-this would be negative, the conversion fails. This is useful for
-determining what position to use in a #GES_EDIT_MODE_TRIM if you wish
-to trim to a specific point in the internal content, such as a
-particular scene in a media file.
-
-Note that whilst a clip has no time effects, this second return is
-equivalent to finding the timeline time at which the content of @child
-at @internal_time would be found in the timeline if it had indefinite
-extent in both directions. However, with non-linear time effects this
-second return will be more distinct.
-
-In either case, the returned time would be appropriate to use in
-ges_timeline_element_edit() for #GES_EDIT_MODE_TRIM, and similar, if
-you wish to use a particular internal point as a reference. For
-example, you could choose to end a clip at a certain internal
-'out-point', similar to the #GESTimelineElement:in-point, by
-translating the desired end time into the timeline coordinates, and
-using this position to trim the end of a clip.
-
-See ges_clip_get_internal_time_from_timeline_time(), which performs the
-reverse, or ges_clip_get_timeline_time_from_source_frame() which does
-the same conversion, but using frame numbers.</doc>

-must already have a #GESClip:layer.
-
-The original clip's #GESTimelineElement:duration is reduced such that
-its end point matches the split position. Then a new clip is created in
-the same layer, whose #GESTimelineElement:start matches the split
-position and #GESTimelineElement:duration will be set such that its end
-point matches the old end point of the original clip. Thus, the two
-clips together will occupy the same positions in the timeline as the
-original clip did.
-
-The children of the new clip will be new copies of the original clip's
-children, so it will share the same sources and use the same
-operations.
-
-The new clip will also have its #GESTimelineElement:in-point set so
-that any internal data will appear in the timeline at the same time.
-Thus, when the timeline is played, the playback of data should
-appear the same. This may be complicated by any additional
-#GESEffect-s that have been placed on the original clip that depend on
-the playback time or change the data consumption rate of sources. This
-method will attempt to translate these effects such that the playback
-appears the same. In such complex situations, you may get a better
-result if you place the clip in a separate sub #GESProject, which only
-contains this clip (and its effects), and in the original layer
-create two neighbouring #GESUriClip-s that reference this sub-project,
-but at a different #GESTimelineElement:in-point.</doc>

-           line="365">When a single timeline element is edited within its timeline at some
-position, using ges_timeline_element_edit(), depending on the edit
-mode, its #GESTimelineElement:start, #GESTimelineElement:duration or
-#GESTimelineElement:in-point will be adjusted accordingly. In addition,
-any clips may change #GESClip:layer.
-
-Each edit can be broken down into a combination of three basic edits:
-
-+ MOVE: This moves the start of the element to the edit position.
-+ START-TRIM: This cuts or grows the start of the element, whilst
-  maintaining the time at which its internal content appears in the
-  timeline data output. If the element is made shorter, the data that
-  appeared at the edit position will still appear in the timeline at
-  the same time. If the element is made longer, the data that appeared
-  at the previous start of the element will still appear in the
-  timeline at the same time.
-+ END-TRIM: Similar to START-TRIM, but the end of the element is cut or
-  grown.
-
-In particular, when editing a #GESClip:
-
-+ MOVE: This will set the #GESTimelineElement:start of the clip to the
-  edit position.
-+ START-TRIM: This will set the #GESTimelineElement:start of the clip
-  to the edit position. To keep the end time the same, the
-  #GESTimelineElement:duration of the clip will be adjusted in the
-  opposite direction. In addition, the #GESTimelineElement:in-point of
-  the clip will be shifted such that the content that appeared at the
-  new or previous start time, whichever is latest, still appears at the
-  same timeline time. For example, if a frame appeared at the start of
-  the clip, and the start of the clip is reduced, the in-point of the
-  clip will also reduce such that the frame will appear later within
-  the clip, but at the same timeline position.
-+ END-TRIM: This will set the #GESTimelineElement:duration of the clip
-  such that its end time will match the edit position.
-
-When editing a #GESGroup:
-
-+ MOVE: This will set the #GESGroup:start of the clip to the edit
-  position by shifting all of its children by the same amount. So each
-  child will maintain their relative positions.
-+ START-TRIM: If the group is made shorter, this will START-TRIM any
-  clips under the group that start after the edit position to the same
-  edit position. If the group is made longer, this will START-TRIM any
-  clip under the group whose start matches the start of the group to
-  the same edit position.
-+ END-TRIM: If the group is made shorter, this will END-TRIM any clips
-  under the group that end after the edit position to the same edit
-  position. If the group is made longer, this will END-TRIM any clip
-  under the group whose end matches the end of the group to the same
-  edit position.
-
-When editing a #GESTrackElement, if it has a #GESClip parent, this
-will be edited instead. Otherwise it is edited in the same way as a
-#GESClip.
-
-The layer priority of a #GESGroup is the lowest layer priority of any
-#GESClip underneath it. When a group is edited to a new layer
-priority, it will shift all clips underneath it by the same amount,
-such that their relative layers stay the same.
-
-If the #GESTimeline has a #GESTimeline:snapping-distance, then snapping
-may occur for some of the edges of the **main** edited element:
-
-+ MOVE: The start or end edge of *any* #GESSource under the element may
-  be snapped.
-+ START-TRIM: The start edge of a #GESSource whose start edge touches
-  the start edge of the element may snap.
-+ END-TRIM: The end edge of a #GESSource whose end edge touches the end
-  edge of the element may snap.
-
-These edges may snap with either the start or end edge of *any* other
-#GESSource in the timeline that is not also being moved by the element,
-including those in different layers, if they are within the
-#GESTimeline:snapping-distance. During an edit, only up to one snap can
-occur. This will shift the edit position such that the snapped edges
-will touch once the edit has completed.
-
-Note that snapping can cause an edit to fail where it would have
-otherwise succeeded because it may push the edit position such that the
-edit would result in an unsupported timeline configuration. Similarly,
-snapping can cause an edit to succeed where it would have otherwise
-failed.
-
-For example, in #GES_EDIT_MODE_RIPPLE acting on #GES_EDGE_NONE, the
-main element is the MOVED toplevel of the edited element. Any source
-under the main MOVED toplevel may have its start or end edge snapped.
-Note, these sources cannot snap with each other. The edit may also
-push other elements, but any sources under these elements cannot snap,
-nor can they be snapped with. If a snap does occur, the MOVE of the
-toplevel *and* all other elements pushed by the ripple will be shifted
-by the same amount such that the snapped edges will touch.
-
-You can also find more explanation about the behaviour of those modes at:
-[trim, ripple and roll](http://pitivi.org/manual/trimming.html)
-and [clip management](http://pitivi.org/manual/usingclips.html).</doc>

-The property type must be float or double, and must be a factor of the
-rate, i.e. a value of 2.0 must mean that the media plays twice as fast.
-Several properties may be registered for a single element type,
-provided they all contribute to the rate as independent factors. For
-example, this is true for the "GstPitch::rate" and "GstPitch::tempo"
-properties. These are already registered by default in GES, along with
-#videorate:rate for #videorate and #scaletempo:rate for #scaletempo.
-
-If such a rate property becomes a child property of a #GESEffect upon
-its creation (the element is part of its #GESEffect:bin-description),
-it will be automatically registered as a time property (see
-ges_base_effect_register_time_property()) and will have its time
-translation functions set (see
-ges_base_effect_set_time_translation_funcs()) to use the overall rate
-of the rate properties. Note that if an effect contains a rate
-property as well as a non-rate time property, you should ensure to set
-the time translation functions to some other methods using
-ges_base_effect_set_time_translation_funcs().

-but it can also control other #GESGroup-s). Its children must share
-the same #GESTimeline, but can otherwise lie in separate #GESLayer-s
-and have different timings.
-
-To initialise a group, you may want to use ges_container_group(),
-and similarly use ges_container_ungroup() to dispose of it.
-
-A group will maintain the relative #GESTimelineElement:start times of
-its children, as well as their relative layer #GESLayer:priority.
-Therefore, if one of its children has its #GESTimelineElement:start
-set, all other children will have their #GESTimelineElement:start
-shifted by the same amount. Similarly, if one of its children moves to
-a new layer, the other children will also change layers to maintain the
-difference in their layer priorities. For example, if a child moves
-from a layer with #GESLayer:priority 1 to a layer with priority 3, then
-another child that was in a layer with priority 0 will move to the
-layer with priority 2.
-
-The #GESGroup:start of a group refers to the earliest start
-time of its children. If the group's #GESGroup:start is set, all the
-children will be shifted equally such that the earliest start time
-will match the set value. The #GESGroup:duration of a group is the
-difference between the earliest start time and latest end time of its
-children. If the group's #GESGroup:duration is increased, the children
-whose end time matches the end of the group will be extended
-accordingly. If it is decreased, then any child whose end time exceeds
-the new end time will also have their duration decreased accordingly.
-
-A group may span several layers, but for methods such as
-ges_timeline_element_get_layer_priority() and
-ges_timeline_element_edit() a group is considered to have a layer
-priority that is the highest #GESLayer:priority (numerically, the
-smallest) of all the layers it spans.</doc>

-A layer within a timeline will have an associated priority,
-corresponding to their index within the timeline. A layer with the
-index/priority 0 will have the highest priority and the layer with the
-largest index will have the lowest priority (the order of priorities,
-in this sense, is the _reverse_ of the numerical ordering of the
-indices). ges_timeline_move_layer() should be used if you wish to
-change how layers are prioritised in a timeline.
-
-Layers with higher priorities will have their content priorities
-over content from lower priority layers, similar to how layers are
-used in image editing. For example, if two separate layers both
-display video content, then the layer with the higher priority will

-ges_meta_container_set_meta() can be used to store any #GValue under
-any generic field (specified by a string key). The same method can also
-be used to remove the field by passing %NULL. A number of convenience
-methods are also provided to make it easier to set common value types.
-The metadata can then be read with ges_meta_container_get_meta() and
-similar convenience methods.
-
-## Registered Fields
-
-By default, any #GValue can be set for a metadata field. However, you
-can register some fields as static, that is they only allow values of a
-specific type to be set under them, using
-ges_meta_container_register_meta() or
-ges_meta_container_register_static_meta(). The set #GESMetaFlag will
-determine whether the value can be changed, but even if it can be
-changed, it must be changed to a value of the same type.
-
-Internally, some GES objects will be initialized with static metadata
-fields. These will correspond to some standard keys, such as
-#GES_META_VOLUME.</doc>

-           line="20">The #GESProject is used to control a set of #GESAsset and is a
-#GESAsset with `GES_TYPE_TIMELINE` as @extractable_type itself. That
-means that you can extract #GESTimeline from a project as followed:
-
-|[
- GESProject *project;
- GESTimeline *timeline;
-
- project = ges_project_new ("file:///path/to/a/valid/project/uri");
-
- // Here you can connect to the various signal to get more infos about
- // what is happening and recover from errors if possible
- ...
-
- timeline = ges_asset_extract (GES_ASSET (project));
-]|
-
-The #GESProject class offers a higher level API to handle #GESAsset-s.
-It lets you request new asset, and it informs you about new assets through
-a set of signals. Also it handles problem such as missing files/missing
-#GstElement and lets you try to recover from those.
-
-## Subprojects
-
-In order to add a subproject, the only thing to do is to add the subproject
-to the main project:
-
-``` c
-ges_project_add_asset (project, GES_ASSET (subproject));
-```
-then the subproject will be serialized in the project files. To use
-the subproject in a timeline, you should use a #GESUriClip with the
-same subproject URI.
-
-When loading a project with subproject, subprojects URIs will be temporary
-writable local files. If you want to edit the subproject timeline,
-you should retrieve the subproject from the parent project asset list and
-extract the timeline with ges_asset_extract() and save it at
-the same temporary location.</doc>

-## Asset
-
-The default asset ID is GESTestClip, but the framerate and video
-size can be overridden using an ID of the form:
-
-```
-framerate=60/1, width=1920, height=1080, max-duration=5.0

-
-A timeline is composed of a set of #GESTrack-s and a set of
-#GESLayer-s, which are added to the timeline using
-ges_timeline_add_track() and ges_timeline_append_layer(), respectively.
-
-The contained tracks define the supported types of the timeline
-and provide the media output. Essentially, each track provides an
-additional source #GstPad.
-
-Most usage of a timeline will likely only need a single #GESAudioTrack
-and/or a single #GESVideoTrack. You can create such a timeline with
-ges_timeline_new_audio_video(). After this, you are unlikely to need to
-work with the tracks directly.
-
-A timeline's layers contain #GESClip-s, which in turn control the
-creation of #GESTrackElement-s, which are added to the timeline's
-tracks. See #GESTimeline::select-tracks-for-object if you wish to have
-more control over which track a clip's elements are added to.
-
-The layers are ordered, with higher priority layers having their
-content prioritised in the tracks. This ordering can be changed using
-ges_timeline_move_layer().
-
-## Editing
-
-See #GESTimelineElement for the various ways the elements of a timeline
-can be edited.
-
-If you change the timing or ordering of a timeline's
-#GESTimelineElement-s, then these changes will not actually be taken
-into account in the output of the timeline's tracks until the
-ges_timeline_commit() method is called. This allows you to move its
-elements around, say, in response to an end user's mouse dragging, with
-little expense before finalising their effect on the produced data.
-
-## Overlaps and Auto-Transitions
-
-There are certain restrictions placed on how #GESSource-s may overlap
-in a #GESTrack that belongs to a timeline. These will be enforced by
-GES, so the user will not need to keep track of them, but they should
-be aware that certain edits will be refused as a result if the overlap
-rules would be broken.
-
-Consider two #GESSource-s, `A` and `B`, with start times `startA` and
-`startB`, and end times `endA` and `endB`, respectively. The start
-time refers to their #GESTimelineElement:start, and the end time is
-their #GESTimelineElement:start + #GESTimelineElement:duration. These
-two sources *overlap* if:
-
-+ they share the same #GESTrackElement:track (non %NULL), which belongs
-  to the timeline;
-+ they share the same #GES_TIMELINE_ELEMENT_LAYER_PRIORITY; and
-+ `startA &lt; endB` and `startB &lt; endA `.
-
-Note that when `startA = endB` or `startB = endA` then the two sources
-will *touch* at their edges, but are not considered overlapping.
-
-If, in addition, `startA &lt; startB &lt; endA`, then we can say that the
-end of `A` overlaps the start of `B`.
-
-If, instead, `startA &lt;= startB` and `endA &gt;= endB`, then we can say
-that `A` fully overlaps `B`.
-
-The overlap rules for a timeline are that:
-
-1. One source cannot fully overlap another source.
-2. A source can only overlap the end of up to one other source at its
-   start.
-3. A source can only overlap the start of up to one other source at its
-   end.
-
-The last two rules combined essentially mean that at any given timeline
-position, only up to two #GESSource-s may overlap at that position. So
-triple or more overlaps are not allowed.
-
-If you switch on #GESTimeline:auto-transition, then at any moment when
-the end of one source (the first source) overlaps the start of another
-(the second source), a #GESTransitionClip will be automatically created
-for the pair in the same layer and it will cover their overlap. If the
-two elements are edited in a way such that the end of the first source
-no longer overlaps the start of the second, the transition will be
-automatically removed from the timeline. However, if the two sources
-still overlap at the same edges after the edit, then the same
-transition object will be kept, but with its timing and layer adjusted
-accordingly.
-
-## Saving
-
-To save/load a timeline, you can use the ges_timeline_load_from_uri()
-and ges_timeline_save_to_uri() methods that use the default format.
-
-## Playing
-
-A timeline is a #GstBin with a source #GstPad for each of its
-tracks, which you can fetch with ges_timeline_get_pad_for_track(). You
-will likely want to link these to some compatible sink #GstElement-s to
-be able to play or capture the content of the timeline.
-
-You can use a #GESPipeline to easily preview/play the timeline's
-content, or render it to a file.</doc>

-tracks a clip's children should be added to. The track element will
-be added to each of the tracks given in the return. If a track
-element is selected to go into multiple tracks, it will be copied
-into the additional tracks, under the same clip. Note that the copy
-will *not* keep its properties or state in sync with the original.
-
-Connect to this signal once if you wish to control which element
-should be added to which track. Doing so will overwrite the default
-behaviour, which adds @track_element to all tracks whose
-#GESTrack:track-type includes the @track_element's
-#GESTrackElement:track-type.
-
-Note that under the default track selection, if a clip would produce
-multiple core children of the same #GESTrackType, it will choose
-one of the core children arbitrarily to place in the corresponding
-tracks, with a warning for the other core children that are not
-placed in the track. For example, this would happen for a #GESUriClip
-that points to a file that contains multiple audio streams. If you
-wish to choose the stream, you could connect to this signal, and use,
-say, ges_uri_source_asset_get_stream_info() to choose which core
-source to add.
-
-When a clip is first added to a timeline, its core elements will
-be created for the current tracks in the timeline if they have not
-already been created. Then this will be emitted for each of these
-core children to select which tracks, if any, they should be added
-to. It will then be called for any non-core children in the clip.
-
-In addition, if a new track element is ever added to a clip in a
-timeline (and it is not already part of a track) this will be emitted
-to select which tracks the element should be added to.
-
-Finally, as a special case, if a track is added to the timeline
-*after* it already contains clips, then it will request the creation
-of the clips' core elements of the corresponding type, if they have
-not already been created, and this signal will be emitted for each of
-these newly created elements. In addition, this will also be released
-for all other track elements in the timeline's clips that have not
-yet been assigned a track. However, in this final case, the timeline
-will only check whether the newly added track appears in the track
-list. If it does appear, the track element will be added to the newly
-added track. All other tracks in the returned track list are ignored.
-
-In this latter case, track elements that are already part of a track
-will not be asked if they want to be copied into the new track. If
-you wish to do this, you can use ges_clip_add_child_to_track().
-
-Note that the returned #GPtrArray should own a new reference to each
-of its contained #GESTrack. The timeline will set the #GDestroyNotify
-free function on the #GPtrArray to dereference the elements.</doc>

-           line="19">A #GESTimelineElement will have some temporal extent in its
-corresponding #GESTimelineElement:timeline, controlled by its
-#GESTimelineElement:start and #GESTimelineElement:duration. This
-determines when its content will be displayed, or its effect applied,
-in the timeline. Several objects may overlap within a given
-#GESTimeline, in which case their #GESTimelineElement:priority is used
-to determine their ordering in the timeline. Priority is mostly handled
-internally by #GESLayer-s and #GESClip-s.
-
-A timeline element can have a #GESTimelineElement:parent,
-such as a #GESClip, which is responsible for controlling its timing.
-
-## Editing
-
-Elements can be moved around in their #GESTimelineElement:timeline by
-setting their #GESTimelineElement:start and
-#GESTimelineElement:duration using ges_timeline_element_set_start()
-and ges_timeline_element_set_duration(). Additionally, which parts of
-the underlying content are played in the timeline can be adjusted by
-setting the #GESTimelineElement:in-point using
-ges_timeline_element_set_inpoint(). The library also provides
-ges_timeline_element_edit(), with various #GESEditMode-s, which can
-adjust these properties in a convenient way, as well as introduce
-similar changes in neighbouring or later elements in the timeline.
-
-However, a timeline may refuse a change in these properties if they
-would place the timeline in an unsupported configuration. See
-#GESTimeline for its overlap rules.
-
-Additionally, an edit may be refused if it would place one of the
-timing properties out of bounds (such as a negative time value for
-#GESTimelineElement:start, or having insufficient internal
-content to last for the desired #GESTimelineElement:duration).
-
-## Time Coordinates
-
-There are three main sets of time coordinates to consider when using
-timeline elements:
-
-+ Timeline coordinates: these are the time coordinates used in the
-  output of the timeline in its #GESTrack-s. Each track share the same
-  coordinates, so there is only one set of coordinates for the
-  timeline. These extend indefinitely from 0. The times used for
-  editing (including setting #GESTimelineElement:start and
-  #GESTimelineElement:duration) use these coordinates, since these
-  define when an element is present and for how long the element lasts
-  for in the timeline.
-+ Internal source coordinates: these are the time coordinates used
-  internally at the element's output. This is only really defined for
-  #GESTrackElement-s, where it refers to time coordinates used at the
-  final source pad of the wrapped #GstElement-s. However, these
-  coordinates may also be used in a #GESClip in reference to its
-  children. In particular, these are the coordinates used for
-  #GESTimelineElement:in-point and #GESTimelineElement:max-duration.
-+ Internal sink coordinates: these are the time coordinates used
-  internally at the element's input. A #GESSource has no input, so
-  these would be undefined. Otherwise, for most #GESTrackElement-s
-  these will be the same set of coordinates as the internal source
-  coordinates because the element does not change the timing
-  internally. Only #GESBaseEffect can support elements where these
-  are different. See #GESBaseEffect for more information.
-
-You can determine the timeline time for a given internal source time
-in a #GESTrack in a #GESClip using
-ges_clip_get_timeline_time_from_internal_time(), and vice versa using
-ges_clip_get_internal_time_from_timeline_time(), for the purposes of
-editing and setting timings properties.
-
-## Children Properties
-
-If a timeline element owns another #GstObject and wishes to expose
-some of its properties, it can do so by registering the property as one
-of the timeline element's children properties using
-ges_timeline_element_add_child_property(). The registered property of
-the child can then be read and set using the
-ges_timeline_element_get_child_property() and
-ges_timeline_element_set_child_property() methods, respectively. Some
-sub-classed objects will be created with pre-registered children
-properties; for example, to expose part of an underlying #GstElement
-that is used internally. The registered properties can be listed with
-ges_timeline_element_list_children_properties().</doc>

-essentially provides an additional #GstPad for the timeline, with
-#GESTrack:restriction-caps capabilities. Internally, a track
-wraps an #nlecomposition filtered by a #capsfilter.
-
-A track will contain a number of #GESTrackElement-s, and its role is
-to select and activate these elements according to their timings when
-the timeline in played. For example, a track would activate a
-#GESSource when its #GESTimelineElement:start is reached by outputting
-its data for its #GESTimelineElement:duration. Similarly, a
-#GESOperation would be activated by applying its effect to the source
-data, starting from its #GESTimelineElement:start time and lasting for
-its #GESTimelineElement:duration.
-
-For most users, it will usually be sufficient to add newly created
-tracks to a timeline, but never directly add an element to a track.
-Whenever a #GESClip is added to a timeline, the clip adds its
-elements to the timeline's tracks and assumes responsibility for
-updating them.</doc>

-to a single #GESTrack of its #GESTimelineElement:timeline. Its
-#GESTimelineElement:start and #GESTimelineElement:duration specify its
-temporal extent in the track. Specifically, a track element wraps some
-nleobject, such as an #nlesource or #nleoperation, which can be
-retrieved with ges_track_element_get_nleobject(), and its
-#GESTimelineElement:start, #GESTimelineElement:duration,
-#GESTimelineElement:in-point, #GESTimelineElement:priority and
-#GESTrackElement:active properties expose the corresponding nleobject
-properties. When a track element is added to a track, its nleobject is
-added to the corresponding #nlecomposition that the track wraps.
-
-Most users will not have to work directly with track elements since a
-#GESClip will automatically create track elements for its timeline's
-tracks and take responsibility for updating them. The only track
-elements that are not automatically created by clips, but a user is
-likely to want to create, are #GESEffect-s.
-
-## Control Bindings for Children Properties
-
-You can set up control bindings for a track element child property
-using ges_track_element_set_control_source(). A
-#GstTimedValueControlSource should specify the timed values using the
-internal source coordinates (see #GESTimelineElement). By default,
-these will be updated to lie between the #GESTimelineElement:in-point
-and out-point of the element. This can be switched off by setting
-#GESTrackElement:auto-clamp-control-sources to %FALSE.</doc>

-For most #GESOperation-s you will likely want to leave this set to

-
-For example, you may want to set this to %TRUE for a

-data. The #GESTimelineElement:in-point of the element would be used
-to shift the initial seek time on the #textoverlay away from 0, and
-the #GESTimelineElement:max-duration could be set to reflect the

-managed as a group.
-Pads from the child elements can be ghosted to the bin, see #GstGhostPad.
-This makes the bin look like any other elements and enables creation of
-higher-level abstraction elements.
-
-A new #GstBin is created with gst_bin_new(). Use a #GstPipeline instead if you
-want to create a toplevel bin because a normal bin doesn't have a bus or
-handle clock distribution of its own.
-
-After the bin has been created you will typically add elements to it with
-gst_bin_add(). You can remove elements with gst_bin_remove().
-
-An element can be retrieved from a bin with gst_bin_get_by_name(), using the
-elements name. gst_bin_get_by_name_recurse_up() is mainly used for internal
-purposes and will query the parent bins when the element is not found in the
-current bin.
-
-An iterator of elements in a bin can be retrieved with
-gst_bin_iterate_elements(). Various other iterators exist to retrieve the
-elements in a bin.
-
-gst_object_unref() is used to drop your reference to the bin.
-
-The #GstBin::element-added signal is fired whenever a new element is added to
-the bin. Likewise the #GstBin::element-removed signal is fired whenever an
-element is removed from the bin.
-
-## Notes
-
-A #GstBin internally intercepts every #GstMessage posted by its children and
-implements the following default behaviour for each of them:
-
-* GST_MESSAGE_EOS: This message is only posted by sinks in the PLAYING
-state. If all sinks posted the EOS message, this bin will post and EOS
-message upwards.
-
-* GST_MESSAGE_SEGMENT_START: Just collected and never forwarded upwards.
-The messages are used to decide when all elements have completed playback
-of their segment.
-
-* GST_MESSAGE_SEGMENT_DONE: Is posted by #GstBin when all elements that posted
-a SEGMENT_START have posted a SEGMENT_DONE.
-
-* GST_MESSAGE_DURATION_CHANGED: Is posted by an element that detected a change
-in the stream duration. The duration change is posted to the
-application so that it can refetch the new duration with a duration
-query. Note that these messages can be posted before the bin is
-prerolled, in which case the duration query might fail. Note also that
-there might be a discrepancy (due to internal buffering/queueing) between the
-stream being currently displayed and the returned duration query.
-Applications might want to also query for duration (and changes) by
-listening to the GST_MESSAGE_STREAM_START message, signaling the active start
-of a (new) stream.
-
-* GST_MESSAGE_CLOCK_LOST: This message is posted by an element when it
-can no longer provide a clock. The default bin behaviour is to
-check if the lost clock was the one provided by the bin. If so and
-the bin is currently in the PLAYING state, the message is forwarded to
-the bin parent.
-This message is also generated when a clock provider is removed from
-the bin. If this message is received by the application, it should
-PAUSE the pipeline and set it back to PLAYING to force a new clock
-distribution.
-
-* GST_MESSAGE_CLOCK_PROVIDE: This message is generated when an element
-can provide a clock. This mostly happens when a new clock
-provider is added to the bin. The default behaviour of the bin is to
-mark the currently selected clock as dirty, which will perform a clock
-recalculation the next time the bin is asked to provide a clock.
-This message is never sent tot the application but is forwarded to
-the parent of the bin.
-
-* OTHERS: posted upwards.
-
-A #GstBin implements the following default behaviour for answering to a
-#GstQuery:
-
-* GST_QUERY_DURATION: The bin will forward the query to all sink
-elements contained within and will return the maximum value.
-If no sinks are available in the bin, the query fails.
-
-* GST_QUERY_POSITION:The query is sent to all sink elements in the bin and the
-MAXIMUM of all values is returned. If no sinks are available in the bin,
-the query fails.
-
-* OTHERS:the query is forwarded to all sink elements, the result
-of the first sink that answers the query successfully is returned. If no
-sink is in the bin, the query fails.
-
-A #GstBin will by default forward any event sent to it to all sink
-(#GST_EVENT_TYPE_DOWNSTREAM) or source (#GST_EVENT_TYPE_UPSTREAM) elements
-depending on the event type.
-If all the elements return %TRUE, the bin will also return %TRUE, else %FALSE
-is returned. If no elements of the required type are in the bin, the event
-handler will return %TRUE.</doc>

-           line="23">Buffers are the basic unit of data transfer in GStreamer. They contain the
-timing and offset along with other arbitrary metadata that is associated
-with the #GstMemory blocks that the buffer contains.
-
-Buffers are usually created with gst_buffer_new(). After a buffer has been
-created one will typically allocate memory for it and add it to the buffer.
-The following example creates a buffer that can hold a given video frame
-with a given width, height and bits per plane.
-|[&lt;!-- language="C" --&gt;
-  GstBuffer *buffer;
-  GstMemory *memory;
-  gint size, width, height, bpp;
-  ...
-  size = width * height * bpp;
-  buffer = gst_buffer_new ();
-  memory = gst_allocator_alloc (NULL, size, NULL);
-  gst_buffer_insert_memory (buffer, -1, memory);
-  ...
-]|
-
-Alternatively, use gst_buffer_new_allocate() to create a buffer with
-preallocated data of a given size.
-
-Buffers can contain a list of #GstMemory objects. You can retrieve how many
-memory objects with gst_buffer_n_memory() and you can get a pointer
-to memory with gst_buffer_peek_memory()
-
-A buffer will usually have timestamps, and a duration, but neither of these
-are guaranteed (they may be set to #GST_CLOCK_TIME_NONE). Whenever a
-meaningful value can be given for these, they should be set. The timestamps
-and duration are measured in nanoseconds (they are #GstClockTime values).
-
-The buffer DTS refers to the timestamp when the buffer should be decoded and
-is usually monotonically increasing. The buffer PTS refers to the timestamp when
-the buffer content should be presented to the user and is not always
-monotonically increasing.
-
-A buffer can also have one or both of a start and an end offset. These are
-media-type specific. For video buffers, the start offset will generally be
-the frame number. For audio buffers, it will be the number of samples
-produced so far. For compressed data, it could be the byte offset in a
-source or destination file. Likewise, the end offset will be the offset of
-the end of the buffer. These can only be meaningfully interpreted if you
-know the media type of the buffer (the preceding CAPS event). Either or both
-can be set to #GST_BUFFER_OFFSET_NONE.
-
-gst_buffer_ref() is used to increase the refcount of a buffer. This must be
-done when you want to keep a handle to the buffer after pushing it to the
-next element. The buffer refcount determines the writability of the buffer, a
-buffer is only writable when the refcount is exactly 1, i.e. when the caller
-has the only reference to the buffer.
-
-To efficiently create a smaller buffer out of an existing one, you can
-use gst_buffer_copy_region(). This method tries to share the memory objects
-between the two buffers.
-
-If a plug-in wants to modify the buffer data or metadata in-place, it should
-first obtain a buffer that is safe to modify by using
-gst_buffer_make_writable().  This function is optimized so that a copy will
-only be made when it is necessary.
-
-Several flags of the buffer can be set and unset with the
-GST_BUFFER_FLAG_SET() and GST_BUFFER_FLAG_UNSET() macros. Use
-GST_BUFFER_FLAG_IS_SET() to test if a certain #GstBufferFlags flag is set.
-
-Buffers can be efficiently merged into a larger buffer with
-gst_buffer_append(). Copying of memory will only be done when absolutely
-needed.
-
-Arbitrary extra metadata can be set on a buffer with gst_buffer_add_meta().
-Metadata can be retrieved with gst_buffer_get_meta(). See also #GstMeta
-
-An element should either unref the buffer or push it out on a src pad
-using gst_pad_push() (see #GstPad).
-
-Buffers are usually freed by unreffing them with gst_buffer_unref(). When
-the refcount drops to 0, any memory and metadata pointed to by the buffer is
-unreffed as well. Buffers allocated from a #GstBufferPool will be returned to
-the pool when the refcount drops to 0.
-
-The #GstParentBufferMeta is a meta which can be attached to a #GstBuffer
-to hold a reference to another buffer that is only released when the child
-#GstBuffer is released.
-
-Typically, #GstParentBufferMeta is used when the child buffer is directly
-using the #GstMemory of the parent buffer, and wants to prevent the parent
-buffer from being returned to a buffer pool until the #GstMemory is available
-for re-use. (Since: 1.6)</doc>

-buffers of the same size and with the same properties.
-
-A #GstBufferPool is created with gst_buffer_pool_new().
-
-Once a pool is created, it needs to be configured. A call to
-gst_buffer_pool_get_config() returns the current configuration structure from
-the pool. With gst_buffer_pool_config_set_params() and
-gst_buffer_pool_config_set_allocator() the bufferpool parameters and
-allocator can be configured. Other properties can be configured in the pool
-depending on the pool implementation.
-
-A bufferpool can have extra options that can be enabled with
-gst_buffer_pool_config_add_option(). The available options can be retrieved
-with gst_buffer_pool_get_options(). Some options allow for additional
-configuration properties to be set.
-
-After the configuration structure has been configured,
-gst_buffer_pool_set_config() updates the configuration in the pool. This can
-fail when the configuration structure is not accepted.
-
-After the a pool has been configured, it can be activated with
-gst_buffer_pool_set_active(). This will preallocate the configured resources
-in the pool.
-
-When the pool is active, gst_buffer_pool_acquire_buffer() can be used to
-retrieve a buffer from the pool.
-
-Buffers allocated from a bufferpool will automatically be returned to the
-pool with gst_buffer_pool_release_buffer() when their refcount drops to 0.
-
-The bufferpool can be deactivated again with gst_buffer_pool_set_active().
-All further gst_buffer_pool_acquire_buffer() calls will return an error. When
-all buffers are returned to the pool they will be freed.
-
-Use gst_object_unref() to release the reference to a bufferpool. If the
-refcount of the pool reaches 0, the pool will be freed.</doc>

-           line="22">The #GstBus is an object responsible for delivering #GstMessage packets in
-a first-in first-out way from the streaming threads (see #GstTask) to the
-application.
-
-Since the application typically only wants to deal with delivery of these
-messages from one thread, the GstBus will marshall the messages between
-different threads. This is important since the actual streaming of media
-is done in another thread than the application.
-
-The GstBus provides support for #GSource based notifications. This makes it
-possible to handle the delivery in the glib mainloop.
-
-The #GSource callback function gst_bus_async_signal_func() can be used to
-convert all bus messages into signal emissions.
-
-A message is posted on the bus with the gst_bus_post() method. With the
-gst_bus_peek() and gst_bus_pop() methods one can look at or retrieve a
-previously posted message.
-
-The bus can be polled with the gst_bus_poll() method. This methods blocks
-up to the specified timeout value until one of the specified messages types
-is posted on the bus. The application can then gst_bus_pop() the messages
-from the bus to handle them.
-Alternatively the application can register an asynchronous bus function
-using gst_bus_add_watch_full() or gst_bus_add_watch(). This function will
-install a #GSource in the default glib main loop and will deliver messages
-a short while after they have been posted. Note that the main loop should
-be running for the asynchronous callbacks.
-
-It is also possible to get messages from the bus without any thread
-marshalling with the gst_bus_set_sync_handler() method. This makes it
-possible to react to a message in the same thread that posted the
-message on the bus. This should only be used if the application is able
-to deal with messages from different threads.
-
-Every #GstPipeline has one bus.
-
-Note that a #GstPipeline will set its bus into flushing state when changing
-from READY to NULL state.</doc>

-You can specify a maximum time to poll with the @timeout parameter. If
-@timeout is negative, this function will block indefinitely.
-
-All messages not in @events will be popped off the bus and will be ignored.
-It is not possible to use message enums beyond #GST_MESSAGE_EXTENDED in the
-@events mask
-
-Because poll is implemented using the "message" signal enabled by
-gst_bus_add_signal_watch(), calling gst_bus_poll() will cause the "message"
-signal to be emitted for every message that poll sees. Thus a "message"
-signal handler will see the same messages that this function sees -- neither
-will steal messages from the other.
-
-This function will run a main loop from the default main context when
-polling.
-
-You should never use this function, since it is pure evil. This is
-especially true for GUI applications based on Gtk+ or Qt, but also for any
-other non-trivial application that uses the GLib main loop. As this function
-runs a GLib main loop, any callback attached to the default GLib main
-context may be invoked. This could be timeouts, GUI events, I/O events etc.;
-even if gst_bus_poll() is called with a 0 timeout. Any of these callbacks
-may do things you do not expect, e.g. destroy the main application window or
-some other resource; change other application state; display a dialog and
-run another main loop until the user clicks it away. In short, using this
-function may add a lot of complexity to your code through unexpected
-re-entrancy and unexpected changes to your application's state.
-
-For 0 timeouts use gst_bus_pop_filtered() instead of this function; for
-other short timeouts use gst_bus_timed_pop_filtered(); everything else is
-better handled by setting up an asynchronous bus watch and doing things
-from there.</doc>

-           line="20">Caps (capabilities) are lightweight refcounted objects describing media types.
-They are composed of an array of #GstStructure.
-
-Caps are exposed on #GstPadTemplate to describe all possible types a
-given pad can handle. They are also stored in the #GstRegistry along with
-a description of the #GstElement.
-
-Caps are exposed on the element pads using the gst_pad_query_caps() pad
-function. This function describes the possible types that the pad can
-handle or produce at runtime.
-
-A #GstCaps can be constructed with the following code fragment:
-|[&lt;!-- language="C" --&gt;
-  GstCaps *caps = gst_caps_new_simple ("video/x-raw",
-     "format", G_TYPE_STRING, "I420",
-     "framerate", GST_TYPE_FRACTION, 25, 1,
-     "pixel-aspect-ratio", GST_TYPE_FRACTION, 1, 1,
-     "width", G_TYPE_INT, 320,
-     "height", G_TYPE_INT, 240,
-     NULL);
-]|
-
-A #GstCaps is fixed when it has no properties with ranges or lists. Use
-gst_caps_is_fixed() to test for fixed caps. Fixed caps can be used in a
-caps event to notify downstream elements of the current media type.
-
-Various methods exist to work with the media types such as subtracting
-or intersecting.
-
-Be aware that the current #GstCaps / #GstStructure serialization into string
-has limited support for nested #GstCaps / #GstStructure fields. It can only
-support one level of nesting. Using more levels will lead to unexpected
-behavior when using serialization features, such as gst_caps_to_string() or
-gst_value_serialize() and their counterparts.</doc>

-If a pad supports multiple sets of features it has to add multiple equal
-structures with different feature sets to the caps.

-Empty #GstCapsFeatures are equivalent with the #GstCapsFeatures that only
-contain #GST_CAPS_FEATURE_MEMORY_SYSTEM_MEMORY. ANY #GstCapsFeatures as
-created by gst_caps_features_new_any() are equal to any other #GstCapsFeatures
-and can be used to specify that any #GstCapsFeatures would be supported, e.g.
-for elements that don't touch buffer memory. #GstCaps with ANY #GstCapsFeatures
-are considered non-fixed and during negotiation some #GstCapsFeatures have
-to be selected.
-
-Examples for caps features would be the requirement of a specific #GstMemory
-types or the requirement of having a specific #GstMeta on the buffer. Features
-are given as a string of the format "memory:GstMemoryTypeName" or
-"meta:GstMetaAPIName".</doc>

-@GST_CAPS_INTERSECT_ZIG_ZAG tries to preserve overall order of both caps
-by iterating on the caps' structures as the following matrix shows:
-|[
-         caps1
-      +-------------
-      | 1  2  4  7
-caps2 | 3  5  8 10
-      | 6  9 11 12
-]|
-Used when there is no explicit precedence of one caps over the other. e.g.
-tee's sink pad getcaps function, it will probe its src pad peers' for their
-caps and intersect them with this mode.
-
-@GST_CAPS_INTERSECT_FIRST is useful when an element wants to preserve
-another element's caps priority order when intersecting with its own caps.
-Example: If caps1 is [A, B, C] and caps2 is [E, B, D, A], the result
-would be [A, B], maintaining the first caps priority on the intersection.</doc>

-The element implementing the interface acts as a parent for those child

-By implementing this interface the child properties can be accessed from the
-parent element by using gst_child_proxy_get() and gst_child_proxy_set().

-Property names are written as "child-name::property-name". The whole naming

-           line="24">GStreamer uses a global clock to synchronize the plugins in a pipeline.
-Different clock implementations are possible by implementing this abstract
-base class or, more conveniently, by subclassing #GstSystemClock.
-
-The #GstClock returns a monotonically increasing time with the method
-gst_clock_get_time(). Its accuracy and base time depend on the specific
-clock implementation but time is always expressed in nanoseconds. Since the
-baseline of the clock is undefined, the clock time returned is not
-meaningful in itself, what matters are the deltas between two clock times.
-The time returned by a clock is called the absolute time.
-
-The pipeline uses the clock to calculate the running time. Usually all
-renderers synchronize to the global clock using the buffer timestamps, the
-newsegment events and the element's base time, see #GstPipeline.
-
-A clock implementation can support periodic and single shot clock
-notifications both synchronous and asynchronous.
-
-One first needs to create a #GstClockID for the periodic or single shot
-notification using gst_clock_new_single_shot_id() or
-gst_clock_new_periodic_id().
-
-To perform a blocking wait for the specific time of the #GstClockID use the
-gst_clock_id_wait(). To receive a callback when the specific time is reached
-in the clock use gst_clock_id_wait_async(). Both these calls can be
-interrupted with the gst_clock_id_unschedule() call. If the blocking wait is
-unscheduled a return value of #GST_CLOCK_UNSCHEDULED is returned.
-
-Periodic callbacks scheduled async will be repeatedly called automatically
-until it is unscheduled. To schedule a sync periodic callback,
-gst_clock_id_wait() should be called repeatedly.
-
-The async callbacks can happen from any thread, either provided by the core
-or from a streaming thread. The application should be prepared for this.
-
-A #GstClockID that has been unscheduled cannot be used again for any wait
-operation, a new #GstClockID should be created and the old unscheduled one
-should be destroyed with gst_clock_id_unref().
-
-It is possible to perform a blocking wait on the same #GstClockID from
-multiple threads. However, registering the same #GstClockID for multiple
-async notifications is not possible, the callback will only be called for
-the thread registering the entry last.
-
-None of the wait operations unref the #GstClockID, the owner is responsible
-for unreffing the ids itself. This holds for both periodic and single shot
-notifications. The reason being that the owner of the #GstClockID has to
-keep a handle to the #GstClockID to unblock the wait on FLUSHING events or
-state changes and if the entry would be unreffed automatically, the handle
-might become invalid without any notification.
-
-These clock operations do not operate on the running time, so the callbacks
-will also occur when not in PLAYING state as if the clock just keeps on
-running. Some clocks however do not progress when the element that provided
-the clock is not PLAYING.
-
-When a clock has the #GST_CLOCK_FLAG_CAN_SET_MASTER flag set, it can be
-slaved to another #GstClock with the gst_clock_set_master(). The clock will
-then automatically be synchronized to this master clock by repeatedly
-sampling the master clock and the slave clock and recalibrating the slave
-clock with gst_clock_set_calibration(). This feature is mostly useful for
-plugins that have an internal clock but must operate with another clock
-selected by the #GstPipeline.  They can track the offset and rate difference
-of their internal clock relative to the master clock by using the
-gst_clock_get_calibration() function.
-
-The master/slave synchronisation can be tuned with the #GstClock:timeout,
-#GstClock:window-size and #GstClock:window-threshold properties.
-The #GstClock:timeout property defines the interval to sample the master
-clock and run the calibration functions. #GstClock:window-size defines the
-number of samples to use when calibrating and #GstClock:window-threshold
-defines the minimum number of samples before the calibration is performed.</doc>

-           line="24">#GstContext is a container object used to store contexts like a device
-context, a display server connection and similar concepts that should
-be shared between multiple elements.
-
-Applications can set a context on a complete pipeline by using
-gst_element_set_context(), which will then be propagated to all
-child elements. Elements can handle these in #GstElementClass.set_context()
-and merge them with the context information they already have.
-
-When an element needs a context it will do the following actions in this
-order until one step succeeds:
-1. Check if the element already has a context
-2. Query downstream with GST_QUERY_CONTEXT for the context
-3. Query upstream with GST_QUERY_CONTEXT for the context
-4. Post a GST_MESSAGE_NEED_CONTEXT message on the bus with the required
-   context types and afterwards check if a usable context was set now
-5. Create a context by itself and post a GST_MESSAGE_HAVE_CONTEXT message
-   on the bus.
-
-Bins will catch GST_MESSAGE_NEED_CONTEXT messages and will set any previously
-known context on the element that asks for it if possible. Otherwise the
-application should provide one if it can.
-
-#GstContext&lt;!-- --&gt;s can be persistent.
-A persistent #GstContext is kept in elements when they reach
-%GST_STATE_NULL, non-persistent ones will be removed.
-Also, a non-persistent context won't override a previous persistent
-context set to an element.</doc>

-function over time.
-
-A #GstControlSource is used by first getting an instance of a specific
-control-source, creating a binding for the control-source to the target property
-of the element and then adding the binding to the element. The binding will
-convert the data types and value range to fit to the bound property.
-
-For implementing a new #GstControlSource one has to implement
-#GstControlSourceGetValue and #GstControlSourceGetValueArray functions.
-These are then used by gst_control_source_get_value() and
-gst_control_source_get_value_array() to get values for specific timestamps.</doc>

-&gt;
-&gt; When naming your category, please follow the following conventions to ensure
-&gt; that the pattern matching for categories works as expected. It is not
-&gt; earth-shattering if you don't follow these conventions, but it would be nice
-&gt; for everyone.
-&gt;
-&gt; If you define a category for a plugin or a feature of it, name the category
-&gt; like the feature. So if you wanted to write a "filesrc" element, you would
-&gt; name the category "filesrc". Use lowercase letters only.
-&gt; If you define more than one category for the same element, append an
-&gt; underscore and an identifier to your categories, like this: "filesrc_cache"
-&gt;
-&gt; If you create a library or an application using debugging categories, use a
-&gt; common prefix followed by an underscore for all your categories. GStreamer
-&gt; uses the GST prefix so GStreamer categories look like "GST_STATES". Be sure
-&gt; to include uppercase letters.</doc>

-can be used in a GStreamer pipeline. Please refer to the plugin writers
-guide for more information on creating #GstElement subclasses.
-
-The name of a #GstElement can be get with gst_element_get_name() and set with
-gst_element_set_name().  For speed, GST_ELEMENT_NAME() can be used in the
-core when using the appropriate locking. Do not use this in plug-ins or
-applications in order to retain ABI compatibility.
-
-Elements can have pads (of the type #GstPad).  These pads link to pads on
-other elements.  #GstBuffer flow between these linked pads.
-A #GstElement has a #GList of #GstPad structures for all their input (or sink)
-and output (or source) pads.
-Core and plug-in writers can add and remove pads with gst_element_add_pad()
-and gst_element_remove_pad().
-
-An existing pad of an element can be retrieved by name with
-gst_element_get_static_pad(). A new dynamic pad can be created using
-gst_element_request_pad() with a #GstPadTemplate.
-An iterator of all pads can be retrieved with gst_element_iterate_pads().
-
-Elements can be linked through their pads.
-If the link is straightforward, use the gst_element_link()
-convenience function to link two elements, or gst_element_link_many()
-for more elements in a row.
-Use gst_element_link_filtered() to link two elements constrained by
-a specified set of #GstCaps.
-For finer control, use gst_element_link_pads() and
-gst_element_link_pads_filtered() to specify the pads to link on
-each element by name.
-
-Each element has a state (see #GstState).  You can get and set the state
-of an element with gst_element_get_state() and gst_element_set_state().
-Setting a state triggers a #GstStateChange. To get a string representation
-of a #GstState, use gst_element_state_get_name().
-
-You can get and set a #GstClock on an element using gst_element_get_clock()
-and gst_element_set_clock().
-Some elements can provide a clock for the pipeline if
-the #GST_ELEMENT_FLAG_PROVIDE_CLOCK flag is set. With the
-gst_element_provide_clock() method one can retrieve the clock provided by
-such an element.
-Not all elements require a clock to operate correctly. If the
-#GST_ELEMENT_FLAG_REQUIRE_CLOCK() flag is set, a clock should be set on the
-element with gst_element_set_clock().
-
-Note that clock selection and distribution is normally handled by the
-toplevel #GstPipeline so the clock functions are only to be used in very
-specific situations.</doc>

-and functions to query (parse) received events.
-
-Events are usually created with gst_event_new_*() which takes event-type
-specific parameters as arguments.
-To send an event application will usually use gst_element_send_event() and
-elements will use gst_pad_send_event() or gst_pad_push_event().
-The event should be unreffed with gst_event_unref() if it has not been sent.
-
-Events that have been received can be parsed with their respective
-gst_event_parse_*() functions. It is valid to pass %NULL for unwanted details.
-
-Events are passed between elements in parallel to the data stream. Some events
-are serialized with buffers, others are not. Some events only travel downstream,
-others only upstream. Some events can travel both upstream and downstream.
-
-The events are used to signal special conditions in the datastream such as
-EOS (end of stream) or the start of a new stream-segment.
-Events are also used to flush the pipeline of any pending data.
-
-Most of the event API is used inside plugins. Applications usually only
-construct and use seek events.
-To do that gst_event_new_seek() is used to create a seek event. It takes
-the needed parameters to specify seeking time and mode.

-In order for a decryption element to decrypt media

-protection system specific information necessary to acquire the decryption
-key(s) for that stream. The functions defined here enable this information
-to be passed in events from elements that extract it
-(e.g., ISOBMFF demuxers, MPEG DASH demuxers) to protection decrypter

-Events containing protection system specific information are created using

-using #gst_event_parse_protection.
-
-In Common Encryption, protection system specific information may be located
-within ISOBMFF files, both in movie (moov) boxes and movie fragment (moof)
-boxes; it may also be contained in ContentProtection elements within MPEG
-DASH MPDs. The events created by #gst_event_new_protection contain data
-identifying from which of these locations the encapsulated protection system
-specific information originated. This origin information is required as
-some protection systems use different encodings depending upon where the
-information originates.
-
-The events returned by gst_event_new_protection() are implemented
-in such a way as to ensure that the most recently-pushed protection info
-event of a particular @origin and @system_id will

-The QOS event is generated in an element that wants an upstream
-element to either reduce or increase its rate because of
-high/low CPU load or other resource usage such as network performance or
-throttling. Typically sinks generate these events for each buffer
-they receive.
-
-@type indicates the reason for the QoS event. #GST_QOS_TYPE_OVERFLOW is
-used when a buffer arrived in time or when the sink cannot keep up with
-the upstream datarate. #GST_QOS_TYPE_UNDERFLOW is when the sink is not
-receiving buffers fast enough and thus has to drop late buffers.
-#GST_QOS_TYPE_THROTTLE is used when the datarate is artificially limited
-by the application, for example to reduce power consumption.
-
-@proportion indicates the real-time performance of the streaming in the
-element that generated the QoS event (usually the sink). The value is
-generally computed based on more long term statistics about the streams
-timestamps compared to the clock.
-A value &lt; 1.0 indicates that the upstream element is producing data faster
-than real-time. A value &gt; 1.0 indicates that the upstream element is not
-producing data fast enough. 1.0 is the ideal @proportion value. The
-proportion value can safely be used to lower or increase the quality of
-the element.
-
-@diff is the difference against the clock in running time of the last
-buffer that caused the element to generate the QOS event. A negative value
-means that the buffer with @timestamp arrived in time. A positive value
-indicates how late the buffer with @timestamp was. When throttling is
-enabled, @diff will be set to the requested throttling interval.
-
-@timestamp is the timestamp of the last buffer that cause the element
-to generate the QOS event. It is expressed in running time and thus an ever
-increasing value.
-
-The upstream element can use the @diff and @timestamp values to decide
-whether to process more buffers. For positive @diff, all buffers with
-timestamp &lt;= @timestamp + @diff will certainly arrive late in the sink
-as well. A (negative) @diff value so that @timestamp + @diff would yield a
-result smaller than 0 is not allowed.
-
-The application can use general event probes to intercept the QoS
-event and implement custom application specific QoS handling.</doc>

-The segment event marks the range of buffers to be processed. All

-
-The time value of the segment is used in conjunction with the start

-@time represents the stream_time of a buffer carrying a timestamp of

-The idea here is to create hierarchical element graphs. The bin element
-contains a sub-graph. Now one would like to treat the bin-element like any
-other #GstElement. This is where GhostPads come into play. A GhostPad acts as
-a proxy for another pad. Thus the bin can have sink and source ghost-pads
-that are associated with sink and source pads of the child elements.
-
-If the target pad is known at creation time, gst_ghost_pad_new() is the
-function to use to get a ghost-pad. Otherwise one can use gst_ghost_pad_new_no_target()
-to create the ghost-pad and use gst_ghost_pad_set_target() to establish the
-association later on.
-
-Note that GhostPads add overhead to the data processing of a pipeline.</doc>

-a threadsafe way.
-
-Various GStreamer objects provide access to their internal structures using
-an iterator.
-
-Note that if calling a GstIterator function results in your code receiving
-a refcounted object (with, say, g_value_get_object()), the refcount for that
-object will not be increased. Your code is responsible for taking a reference
-if it wants to continue using it later.
-
-The basic use pattern of an iterator is as follows:
-|[&lt;!-- language="C" --&gt;
-  GstIterator *it = _get_iterator(object);
-  GValue item = G_VALUE_INIT;
-  done = FALSE;
-  while (!done) {
-    switch (gst_iterator_next (it, &amp;amp;item)) {
-      case GST_ITERATOR_OK:
-        ...get/use/change item here...
-        g_value_reset (&amp;amp;item);
-        break;
-      case GST_ITERATOR_RESYNC:
-        ...rollback changes to items...
-        gst_iterator_resync (it);
-        break;
-      case GST_ITERATOR_ERROR:
-        ...wrong parameters were given...
-        done = TRUE;
-        break;
-      case GST_ITERATOR_DONE:
-        done = TRUE;
-        break;
-    }
-  }
-  g_value_unset (&amp;amp;item);

-They are typically used to manage the data of a #GstBuffer.
-
-A GstMemory object has an allocated region of memory of maxsize. The maximum
-size does not change during the lifetime of the memory object. The memory
-also has an offset and size property that specifies the valid range of memory
-in the allocated region.
-
-Memory is usually created by allocators with a gst_allocator_alloc()
-method call. When %NULL is used as the allocator, the default allocator will
-be used.
-
-New allocators can be registered with gst_allocator_register().
-Allocators are identified by name and can be retrieved with
-gst_allocator_find(). gst_allocator_set_default() can be used to change the
-default allocator.
-
-New memory can be created with gst_memory_new_wrapped() that wraps the memory
-allocated elsewhere.
-
-Refcounting of the memory block is performed with gst_memory_ref() and
-gst_memory_unref().
-
-The size of the memory can be retrieved and changed with
-gst_memory_get_sizes() and gst_memory_resize() respectively.
-
-Getting access to the data of the memory is performed with gst_memory_map().
-The call will return a pointer to offset bytes into the region of memory.
-After the memory access is completed, gst_memory_unmap() should be called.
-
-Memory can be copied with gst_memory_copy(), which will return a writable
-copy. gst_memory_share() will create a new memory block that shares the
-memory with an existing memory block at a custom offset and with a custom
-size.
-
-Memory can be efficiently merged when gst_memory_is_span() returns %TRUE.</doc>

-return a non-HTTP URL.
-
-The redirect message can hold multiple entries. The first one is added
-when the redirect message is created, with the given location, tag_list,
-entry_struct arguments. Use gst_message_add_redirect_entry() to add more
-entries.
-
-Each entry has a location, a tag list, and a structure. All of these are
-optional. The tag list and structure are useful for additional metadata,
-such as bitrate statistics for the given location.
-
-By default, message recipients should treat entries in the order they are
-stored. The recipient should therefore try entry \#0 first, and if this
-entry is not acceptable or working, try entry \#1 etc. Senders must make
-sure that they add entries in this order. However, recipients are free to
-ignore the order and pick an entry that is "best" for them. One example
-would be a recipient that scans the entries for the one with the highest
-bitrate tag.

-types.
-
-Subclasses will include #GstMiniObject as the first member in their structure
-and then call gst_mini_object_init() to initialize the #GstMiniObject fields.
-
-gst_mini_object_ref() and gst_mini_object_unref() increment and decrement the
-refcount respectively. When the refcount of a mini-object reaches 0, the
-dispose function is called first and when this returns %TRUE, the free
-function of the miniobject is called.
-
-A copy can be made with gst_mini_object_copy().
-
-gst_mini_object_is_writable() will return %TRUE when the refcount of the
-object is exactly 1 and there is no parent or a single parent exists and is
-writable itself, meaning the current caller has the only reference to the
-object. gst_mini_object_make_writable() will return a writable version of
-the object, which might be a new copy when the refcount was not 1.
-
-Opaque data can be associated with a #GstMiniObject with
-gst_mini_object_set_qdata() and gst_mini_object_get_qdata(). The data is
-meant to be specific to the particular object and is not automatically copied
-with gst_mini_object_copy() or similar methods.
-
-A weak reference can be added and remove with gst_mini_object_weak_ref()
-and gst_mini_object_weak_unref() respectively.</doc>

-GStreamer library.  It is currently a thin wrapper on top of
-#GInitiallyUnowned. It is an abstract class that is not very usable on its own.
-
-#GstObject gives us basic refcounting, parenting functionality and locking.
-Most of the functions are just extended for special GStreamer needs and can be
-found under the same name in the base class of #GstObject which is #GObject
-(e.g. g_object_ref() becomes gst_object_ref()).
-
-Since #GstObject derives from #GInitiallyUnowned, it also inherits the
-floating reference. Be aware that functions such as gst_bin_add() and
-gst_element_add_pad() take ownership of the floating reference.
-
-In contrast to #GObject instances, #GstObject adds a name property. The functions
-gst_object_set_name() and gst_object_get_name() are used to set/get the name
-of the object.
-
-## controlled properties
-
-Controlled properties offers a lightweight way to adjust gobject properties
-over stream-time. It works by using time-stamped value pairs that are queued
-for element-properties. At run-time the elements continuously pull value
-changes for the current stream-time.
-
-What needs to be changed in a #GstElement?
-Very little - it is just two steps to make a plugin controllable!
-
-  * mark gobject-properties paramspecs that make sense to be controlled,
-    by GST_PARAM_CONTROLLABLE.
-
-  * when processing data (get, chain, loop function) at the beginning call
-    gst_object_sync_values(element,timestamp).
-    This will make the controller update all GObject properties that are
-    under its control with the current values based on the timestamp.
-
-What needs to be done in applications? Again it's not a lot to change.
-
-  * create a #GstControlSource.
-    csource = gst_interpolation_control_source_new ();
-    g_object_set (csource, "mode", GST_INTERPOLATION_MODE_LINEAR, NULL);
-
-  * Attach the #GstControlSource on the controller to a property.
-    gst_object_add_control_binding (object, gst_direct_control_binding_new (object, "prop1", csource));
-
-  * Set the control values
-    gst_timed_value_control_source_set ((GstTimedValueControlSource *)csource,0 * GST_SECOND, value1);
-    gst_timed_value_control_source_set ((GstTimedValueControlSource *)csource,1 * GST_SECOND, value2);
-
-  * start your pipeline</doc>

-           line="22">A #GstElement is linked to other elements via "pads", which are extremely
-light-weight generic link points.
-
-Pads have a #GstPadDirection, source pads produce data, sink pads consume
-data.
-
-Pads are typically created from a #GstPadTemplate with
-gst_pad_new_from_template() and are then added to a #GstElement. This usually
-happens when the element is created but it can also happen dynamically based
-on the data that the element is processing or based on the pads that the
-application requests.
-
-Pads without pad templates can be created with gst_pad_new(),
-which takes a direction and a name as an argument.  If the name is %NULL,
-then a guaranteed unique name will be assigned to it.
-
-A #GstElement creating a pad will typically use the various
-gst_pad_set_*_function\() calls to register callbacks for events, queries or
-dataflow on the pads.
-
-gst_pad_get_parent() will retrieve the #GstElement that owns the pad.
-
-After two pads are retrieved from an element by gst_element_get_static_pad(),
-the pads can be linked with gst_pad_link(). (For quick links,
-you can also use gst_element_link(), which will make the obvious
-link for you if it's straightforward.). Pads can be unlinked again with
-gst_pad_unlink(). gst_pad_get_peer() can be used to check what the pad is
-linked to.
-
-Before dataflow is possible on the pads, they need to be activated with
-gst_pad_set_active().
-
-gst_pad_query() and gst_pad_peer_query() can be used to query various
-properties of the pad and the stream.
-
-To send a #GstEvent on a pad, use gst_pad_send_event() and
-gst_pad_push_event(). Some events will be sticky on the pad, meaning that
-after they pass on the pad they can be queried later with
-gst_pad_get_sticky_event() and gst_pad_sticky_events_foreach().
-gst_pad_get_current_caps() and gst_pad_has_current_caps() are convenience
-functions to query the current sticky CAPS event on a pad.
-
-GstElements will use gst_pad_push() and gst_pad_pull_range() to push out
-or pull in a buffer.
-
-The dataflow, events and queries that happen on a pad can be monitored with
-probes that can be installed with gst_pad_add_probe(). gst_pad_is_blocked()
-can be used to check if a block probe is installed on the pad.
-gst_pad_is_blocking() checks if the blocking probe is currently blocking the
-pad. gst_pad_remove_probe() is used to remove a previously installed probe
-and unblock blocking probes if any.
-
-Pad have an offset that can be retrieved with gst_pad_get_offset(). This
-offset will be applied to the running_time of all data passing over the pad.
-gst_pad_set_offset() can be used to change the offset.
-
-Convenience functions exist to start, pause and stop the task on a pad with
-gst_pad_start_task(), gst_pad_pause_task() and gst_pad_stop_task()
-respectively.</doc>

-
-If @pad is a source pad, @event should be an upstream event. If @pad is a
-sink pad, @event should be a downstream event. For example, you would not
-send a #GST_EVENT_EOS on a src pad; EOS events only propagate downstream.
-Furthermore, some downstream events have to be serialized with data flow,
-like EOS, while some can travel out-of-band, like #GST_EVENT_FLUSH_START. If
-the event needs to be serialized with data flow, this function will take the
-pad's stream lock while calling its event function.
-
-To find out whether an event type is upstream, downstream, or downstream and
-serialized, see #GstEventTypeFlags, gst_event_type_get_flags(),
-#GST_EVENT_IS_UPSTREAM, #GST_EVENT_IS_DOWNSTREAM, and
-#GST_EVENT_IS_SERIALIZED. Note that in practice that an application or
-plugin doesn't need to bother itself with this information; the core handles
-all necessary locks and checks.
-

-This function is installed on a source pad with

-
-@offset and @length are always given in byte units. @offset must normally be a value
-between 0 and the length in bytes of the data available on @pad. The
-length (duration in bytes) can be retrieved with a #GST_QUERY_DURATION or with a
-#GST_QUERY_SEEKING.
-
-Any @offset larger or equal than the length will make the function return
-#GST_FLOW_EOS, which corresponds to EOS. In this case @buffer does not
-contain a valid buffer.
-
-The buffer size of @buffer will only be smaller than @length when @offset is
-near the end of the stream. In all other cases, the size of @buffer must be

-It is allowed to call this function with a 0 @length and valid @offset, in
-which case @buffer will contain a 0-sized buffer and the function returns
-#GST_FLOW_OK.

-of length @length in the stream is returned.

-           line="23">Padtemplates describe the possible media types a pad or an elementfactory can
-handle. This allows for both inspection of handled types before loading the
-element plugin as well as identifying pads on elements that are not yet
-created (request or sometimes pads).
-
-Pad and PadTemplates have #GstCaps attached to it to describe the media type
-they are capable of dealing with. gst_pad_template_get_caps() or
-GST_PAD_TEMPLATE_CAPS() are used to get the caps of a padtemplate. It's not
-possible to modify the caps of a padtemplate after creation.
-
-PadTemplates have a #GstPadPresence property which identifies the lifetime
-of the pad and that can be retrieved with GST_PAD_TEMPLATE_PRESENCE(). Also
-the direction of the pad can be retrieved from the #GstPadTemplate with
-GST_PAD_TEMPLATE_DIRECTION().
-
-The GST_PAD_TEMPLATE_NAME_TEMPLATE () is important for GST_PAD_REQUEST pads
-because it has to be used as the name in the gst_element_get_request_pad()
-call to instantiate a pad from this template.
-
-Padtemplates can be created with gst_pad_template_new() or with
-gst_static_pad_template_get (), which creates a #GstPadTemplate from a
-#GstStaticPadTemplate that can be filled with the
-convenient GST_STATIC_PAD_TEMPLATE() macro.
-
-A padtemplate can be used to create a pad (see gst_pad_new_from_template()
-or gst_pad_new_from_static_template ()) or to add to an element class
-(see gst_element_class_add_static_pad_template ()).
-
-The following code example shows the code to create a pad from a padtemplate.
-|[&lt;!-- language="C" --&gt;
-  GstStaticPadTemplate my_template =
-  GST_STATIC_PAD_TEMPLATE (
-    "sink",          // the name of the pad
-    GST_PAD_SINK,    // the direction of the pad
-    GST_PAD_ALWAYS,  // when this pad will be present
-    GST_STATIC_CAPS (        // the capabilities of the padtemplate
-      "audio/x-raw, "
-        "channels = (int) [ 1, 6 ]"
-    )
-  );
-  void
-  my_method (void)
-  {
-    GstPad *pad;
-    pad = gst_pad_new_from_static_template (&amp;amp;my_template, "sink");
-    ...
-  }
-]|
-
-The following example shows you how to add the padtemplate to an
-element class, this is usually done in the class_init of the class:
-|[&lt;!-- language="C" --&gt;
-  static void
-  my_element_class_init (GstMyElementClass *klass)
-  {
-    GstElementClass *gstelement_class = GST_ELEMENT_CLASS (klass);
-
-    gst_element_class_add_static_pad_template (gstelement_class, &amp;amp;my_template);
-  }

-the filter graph. The #GstPipeline will manage the selection and
-distribution of a global #GstClock as well as provide a #GstBus to the
-application.
-
-gst_pipeline_new() is used to create a pipeline. when you are done with
-the pipeline, use gst_object_unref() to free its resources including all
-added #GstElement objects (if not otherwise referenced).
-
-Elements are added and removed from the pipeline using the #GstBin
-methods like gst_bin_add() and gst_bin_remove() (see #GstBin).
-
-Before changing the state of the #GstPipeline (see #GstElement) a #GstBus
-can be retrieved with gst_pipeline_get_bus(). This bus can then be
-used to receive #GstMessage from the elements in the pipeline.
-
-By default, a #GstPipeline will automatically flush the pending #GstBus
-messages when going to the NULL state to ensure that no circular
-references exist when no messages are read from the #GstBus. This
-behaviour can be changed with gst_pipeline_set_auto_flush_bus().
-
-When the #GstPipeline performs the PAUSED to PLAYING state change it will
-select a clock for the elements. The clock selection algorithm will by
-default select a clock provided by an element that is most upstream
-(closest to the source). For live pipelines (ones that return
-#GST_STATE_CHANGE_NO_PREROLL from the gst_element_set_state() call) this
-will select the clock provided by the live source. For normal pipelines
-this will select a clock provided by the sinks (most likely the audio
-sink). If no element provides a clock, a default #GstSystemClock is used.
-
-The clock selection can be controlled with the gst_pipeline_use_clock()
-method, which will enforce a given clock on the pipeline. With
-gst_pipeline_auto_clock() the default clock selection algorithm can be
-restored.
-
-A #GstPipeline maintains a running time for the elements. The running
-time is defined as the difference between the current clock time and
-the base time. When the pipeline goes to READY or a flushing seek is
-performed on it, the running time is reset to 0. When the pipeline is
-set from PLAYING to PAUSED, the current clock time is sampled and used to
-configure the base time for the elements when the pipeline is set
-to PLAYING again. The effect is that the running time (as the difference
-between the clock time and the base time) will count how much time was spent
-in the PLAYING state. This default behaviour can be changed with the
-gst_element_set_start_time() method.</doc>

-A plugin system can provide one or more of the basic GStreamer
-#GstPluginFeature subclasses.
-
-A plugin should export a symbol `gst_plugin_desc` that is a
-struct of type #GstPluginDesc.
-the plugin loader will check the version of the core library the plugin was
-linked against and will create a new #GstPlugin. It will then call the
-#GstPluginInitFunc function that was provided in the
-`gst_plugin_desc`.
-
-Once you have a handle to a #GstPlugin (e.g. from the #GstRegistry), you
-can add any object that subclasses #GstPluginFeature.
-
-Usually plugins are always automatically loaded so you don't need to call
-gst_plugin_load() explicitly to bring it into memory. There are options to
-statically link plugins to an app or even use GStreamer without a plugin
-repository in which case gst_plugin_load() can be needed to bring the plugin
-into memory.</doc>

-
-GStreamer will re-inspect plugins with external dependencies whenever any
-of the external dependencies change. This is useful for plugins which wrap
-other plugin systems, e.g. a plugin which wraps a plugin-based visualisation
-library and makes visualisations available as GStreamer elements, or a
-codec loader which exposes elements and/or caps dependent on what external
-codec libraries are currently installed.
-
-Convenience wrapper function for gst_plugin_add_dependency() which
-takes simple strings as arguments instead of string arrays, with multiple
-arguments separated by predefined delimiters (see above).</doc>

-by specifying %TRUE for the @controllable flag when creating the set (or

-
-New file descriptors are added to the set using gst_poll_add_fd(), and

-should be waited for to become readable and/or writable are done using
-gst_poll_fd_ctl_read(), gst_poll_fd_ctl_write() and gst_poll_fd_ctl_pri().
-
-Use gst_poll_wait() to wait for the file descriptors to actually become
-readable and/or writable, or to timeout if no file descriptor is available
-in time. The wait can be controlled by calling gst_poll_restart() and
-gst_poll_set_flushing().
-
-Once the file descriptor set has been waited for, one can use
-gst_poll_fd_has_closed() to see if the file descriptor has been closed,

-A preset is a bunch of property settings, together with meta data and a name.
-The name of a preset serves as key for subsequent method calls to manipulate
-single presets.
-All instances of one type will share the list of presets. The list is created
-on demand, if presets are not used, the list is not created.
-
-The interface comes with a default implementation that serves most plugins.
-Wrapper plugins will override most methods to implement support for the
-native preset format of those wrapped plugins.
-One method that is useful to be overridden is gst_preset_get_property_names().
-With that one can control which properties are saved and in which order.
-When implementing support for read-only presets, one should set the vmethods
-for gst_preset_save_preset() and gst_preset_delete_preset() to %NULL.
-Applications can use gst_preset_is_editable() to check for that.
-
-The default implementation supports presets located in a system directory,
-application specific directory and in the users home directory. When getting
-a list of presets individual presets are read and overlaid in 1) system,
-2) application and 3) user order. Whenever an earlier entry is newer, the
-later entries will be updated. Since 1.8 you can also provide extra paths
-where to find presets through the GST_PRESET_PATH environment variable.
-Presets found in those paths will be considered as "app presets".</doc>

-           line="31">The #GstPromise object implements the container for values that may
-be available later. i.e. a Future or a Promise in
-&lt;https://en.wikipedia.org/wiki/Futures_and_promises&gt;.
-As with all Future/Promise-like functionality, there is the concept of the
-producer of the value and the consumer of the value.
-
-A #GstPromise is created with gst_promise_new() by the consumer and passed
-to the producer to avoid thread safety issues with the change callback.
-A #GstPromise can be replied to with a value (or an error) by the producer
-with gst_promise_reply(). The exact value returned is defined by the API
-contract of the producer and %NULL may be a valid reply.
-gst_promise_interrupt() is for the consumer to
-indicate to the producer that the value is not needed anymore and producing
-that value can stop.  The @GST_PROMISE_RESULT_EXPIRED state set by a call
-to gst_promise_expire() indicates to the consumer that a value will never
-be produced and is intended to be called by a third party that implements
-some notion of message handling such as #GstBus.
-A callback can also be installed at #GstPromise creation for
-result changes with gst_promise_new_with_change_func().
-The change callback can be used to chain #GstPromises's together as in the
-following example.
-|[&lt;!-- language="C" --&gt;
-const GstStructure *reply;
-GstPromise *p;
-if (gst_promise_wait (promise) != GST_PROMISE_RESULT_REPLIED)
-  return; // interrupted or expired value
-reply = gst_promise_get_reply (promise);
-if (error in reply)
-  return; // propagate error
-p = gst_promise_new_with_change_func (another_promise_change_func, user_data, notify);
-pass p to promise-using API
-]|
-
-Each #GstPromise starts out with a #GstPromiseResult of
-%GST_PROMISE_RESULT_PENDING and only ever transitions once
-into one of the other #GstPromiseResult's.
-
-In order to support multi-threaded code, gst_promise_reply(),
-gst_promise_interrupt() and gst_promise_expire() may all be from
-different threads with some restrictions and the final result of the promise
-is whichever call is made first.  There are two restrictions on ordering:
-
-1. That gst_promise_reply() and gst_promise_interrupt() cannot be called
-after gst_promise_expire()
-2. That gst_promise_reply() and gst_promise_interrupt()
-cannot be called twice.
-
-The change function set with gst_promise_new_with_change_func() is
-called directly from either the gst_promise_reply(),
-gst_promise_interrupt() or gst_promise_expire() and can be called
-from an arbitrary thread.  #GstPromise using APIs can restrict this to
-a single thread or a subset of threads but that is entirely up to the API
-that uses #GstPromise.</doc>

-The CAPS query should return the allowable caps for a pad in the context
-of the element's state, its link to other elements, and the devices or files
-it has opened. These caps must be a subset of the pad template caps. In the
-NULL state with no links, the CAPS query should ideally return the same caps
-as the pad template. In rare circumstances, an object property can affect
-the caps returned by the CAPS query, but this is discouraged.
-
-For most filters, the caps returned by CAPS query is directly affected by the
-allowed caps on other pads. For demuxers and decoders, the caps returned by
-the srcpad's getcaps function is directly related to the stream data. Again,
-the CAPS query should return the most specific caps it reasonably can, since this
-helps with autoplugging.
-
-The @filter is used to restrict the result caps, only the caps matching
-@filter should be returned from the CAPS query. Specifying a filter might
-greatly reduce the amount of processing an element needs to do.

-&lt;emphasis role="bold"&gt;Design:&lt;/emphasis&gt;
-
-The #GstRegistry object is a list of plugins and some functions for dealing
-with them. Each #GstPlugin is matched 1-1 with a file on disk, and may or may
-not be loaded at a given time.
-
-The primary source, at all times, of plugin information is each plugin file
-itself. Thus, if an application wants information about a particular plugin,
-or wants to search for a feature that satisfies given criteria, the primary
-means of doing so is to load every plugin and look at the resulting
-information that is gathered in the default registry. Clearly, this is a time
-consuming process, so we cache information in the registry file. The format
-and location of the cache file is internal to gstreamer.
-
-On startup, plugins are searched for in the plugin search path. The following
-locations are checked in this order:
-
-* location from --gst-plugin-path commandline option.
-* the GST_PLUGIN_PATH environment variable.
-* the GST_PLUGIN_SYSTEM_PATH environment variable.
-* default locations (if GST_PLUGIN_SYSTEM_PATH is not set).
-  Those default locations are:
-  `$XDG_DATA_HOME/gstreamer-$GST_API_VERSION/plugins/`
-  and `$prefix/libs/gstreamer-$GST_API_VERSION/`.
-  [$XDG_DATA_HOME](http://standards.freedesktop.org/basedir-spec/basedir-spec-latest.html) defaults to
-  `$HOME/.local/share`.
-
-The registry cache file is loaded from
-`$XDG_CACHE_HOME/gstreamer-$GST_API_VERSION/registry-$ARCH.bin`
-(where $XDG_CACHE_HOME defaults to `$HOME/.cache`) or the file listed in the `GST_REGISTRY`
-env var. One reason to change the registry location is for testing.
-
-For each plugin that is found in the plugin search path, there could be 3
-possibilities for cached information:
-
-  * the cache may not contain information about a given file.
-  * the cache may have stale information.
-  * the cache may have current information.
-
-In the first two cases, the plugin is loaded and the cache updated. In
-addition to these cases, the cache may have entries for plugins that are not
-relevant to the current process. These are marked as not available to the
-current process. If the cache is updated for whatever reason, it is marked
-dirty.
-
-A dirty cache is written out at the end of initialization. Each entry is
-checked to make sure the information is minimally valid. If not, the entry is
-simply dropped.
-
-## Implementation notes:
-
-The "cache" and "registry" are different concepts and can represent
-different sets of plugins. For various reasons, at init time, the cache is
-stored in the default registry, and plugins not relevant to the current
-process are marked with the %GST_PLUGIN_FLAG_CACHED bit. These plugins are
-removed at the end of initialization.</doc>

-           line="50">Flags to be used with gst_element_seek() or gst_event_new_seek(). All flags
-can be used together.
-
-A non flushing seek might take some time to perform as the currently
-playing data in the pipeline will not be cleared.
-
-An accurate seek might be slower for formats that don't have any indexes
-or timestamp markers in the stream. Specifying this flag might require a
-complete scan of the file in those cases.
-
-When performing a segment seek: after the playback of the segment completes,
-no EOS will be emitted by the element that performed the seek, but a
-%GST_MESSAGE_SEGMENT_DONE message will be posted on the bus by the element.
-When this message is posted, it is possible to send a new seek event to
-continue playback. With this seek method it is possible to perform seamless
-looping or simple linear editing.
-
-When only changing the playback rate and not the direction, the
-%GST_SEEK_FLAG_INSTANT_RATE_CHANGE flag can be used for a non-flushing seek
-to signal that the rate change should be applied immediately. This requires
-special support in the seek handlers (e.g. demuxers) and any elements
-synchronizing to the clock, and in general can't work in all cases (for example
-UDP streaming where the delivery rate is controlled by a remote server). The
-instant-rate-change mode supports changing the trickmode-related GST_SEEK_ flags,
-but can't be used in conjunction with other seek flags that affect the new
-playback position - as the playback position will not be changing.
-
-When doing fast forward (rate &gt; 1.0) or fast reverse (rate &lt; -1.0) trickmode
-playback, the %GST_SEEK_FLAG_TRICKMODE flag can be used to instruct decoders
-and demuxers to adjust the playback rate by skipping frames. This can improve
-performance and decrease CPU usage because not all frames need to be decoded.
-
-Beyond that, the %GST_SEEK_FLAG_TRICKMODE_KEY_UNITS flag can be used to
-request that decoders skip all frames except key units, and
-%GST_SEEK_FLAG_TRICKMODE_NO_AUDIO flags can be used to request that audio
-decoders do no decoding at all, and simple output silence.
-
-The %GST_SEEK_FLAG_SNAP_BEFORE flag can be used to snap to the previous
-relevant location, and the %GST_SEEK_FLAG_SNAP_AFTER flag can be used to
-select the next relevant location. If %GST_SEEK_FLAG_KEY_UNIT is specified,
-the relevant location is a keyframe. If both flags are specified, the nearest
-of these locations will be selected. If none are specified, the implementation is
-free to select whichever it wants.
-
-The before and after here are in running time, so when playing backwards,
-the next location refers to the one that will played in next, and not the
-one that is located after in the actual source stream.
-
-Also see part-seeking.txt in the GStreamer design documentation for more
-details on the meaning of these flags and the behaviour expected of
-elements that handle them.</doc>

-           line="29">This helper structure holds the relevant values for tracking the region of
-interest in a media file, called a segment.
-
-The structure can be used for two purposes:
-
-  * performing seeks (handling seek events)
-  * tracking playback regions (handling newsegment events)
-
-The segment is usually configured by the application with a seek event which
-is propagated upstream and eventually handled by an element that performs the seek.
-
-The configured segment is then propagated back downstream with a newsegment event.
-This information is then used to clip media to the segment boundaries.
-
-A segment structure is initialized with gst_segment_init(), which takes a #GstFormat
-that will be used as the format of the segment values. The segment will be configured
-with a start value of 0 and a stop/duration of -1, which is undefined. The default
-rate and applied_rate is 1.0.
-
-The public duration field contains the duration of the segment. When using
-the segment for seeking, the start and time members should normally be left
-to their default 0 value. The stop position is left to -1 unless explicitly
-configured to a different value after a seek event.
-
-The current position in the segment should be set by changing the position
-member in the structure.
-
-For elements that perform seeks, the current segment should be updated with the
-gst_segment_do_seek() and the values from the seek event. This method will update
-all the segment fields. The position field will contain the new playback position.
-If the start_type was different from GST_SEEK_TYPE_NONE, playback continues from
-the position position, possibly with updated flags or rate.
-
-For elements that want to use #GstSegment to track the playback region,
-update the segment fields with the information from the newsegment event.
-The gst_segment_clip() method can be used to check and clip
-the media data to the segment boundaries.
-
-For elements that want to synchronize to the pipeline clock, gst_segment_to_running_time()
-can be used to convert a timestamp to a value that can be used to synchronize
-to the clock. This function takes into account the base as well as
-any rate or applied_rate conversions.
-
-For elements that need to perform operations on media data in stream_time,
-gst_segment_to_stream_time() can be used to convert a timestamp and the segment
-info to stream time (which is always between 0 and the duration of the stream).</doc>

-               The applied rate can be set by source elements when a server is

-           line="22">A #GstStructure is a collection of key/value pairs. The keys are expressed as
-GQuarks and the values can be of any GType.
-
-In addition to the key/value pairs, a #GstStructure also has a name. The name
-starts with a letter and can be filled by letters, numbers and any of
-"/-_.:".
-
-#GstStructure is used by various GStreamer subsystems to store information in
-a flexible and extensible way. A #GstStructure does not have a refcount
-because it usually is part of a higher level object such as #GstCaps,
-#GstMessage, #GstEvent, #GstQuery. It provides a means to enforce mutability
-using the refcount of the parent with the gst_structure_set_parent_refcount()
-method.
-
-A #GstStructure can be created with gst_structure_new_empty() or
-gst_structure_new(), which both take a name and an optional set of key/value
-pairs along with the types of the values.
-
-Field values can be changed with gst_structure_set_value() or
-gst_structure_set().
-
-Field values can be retrieved with gst_structure_get_value() or the more
-convenient gst_structure_get_*() functions.
-
-Fields can be removed with gst_structure_remove_field() or
-gst_structure_remove_fields().
-
-Strings in structures must be ASCII or UTF-8 encoded. Other encodings are not
-allowed. Strings may be %NULL however.
-
-## The serialization format
-
-GstStructure serialization format serialize the GstStructure name,
-keys/GType/values in a comma separated list with the structure name as first
-field without value followed by separated key/value pairs in the form
-`key=value`, for example:
-
-```
-a-structure, key=value
-````
-
-The values type will be inferred if not explicitly specified with the
-`(GTypeName)value` syntax, for example the following struct will have one
-field called 'is-string' which has the string 'true' as a value:
-
-```
-a-struct, field-is-string=(string)true, field-is-boolean=true
-```
-
-*Note*: without specifying `(string), `field-is-string` type would have been
-inferred as boolean.
-
-*Note*: we specified `(string)` as a type even if `gchararray` is the actual
-GType name as for convenience some well known types have been aliased or
-abbreviated.
-
-To avoid specifying the type, you can give some hints to the "type system".
-For example to specify a value as a double, you should add a decimal (ie. `1`
-is an `int` while `1.0` is a `double`).
-
-*Note*: when a structure is serialized with #gst_structure_to_string, all
-values are explicitly typed.
-
-Some types have special delimiters:
-
-- [GstValueArray](GST_TYPE_ARRAY) are inside curly brackets (`{` and `}`).
-  For example `a-structure, array={1, 2, 3}`
-- Ranges are inside brackets (`[` and `]`). For example `a-structure,
-  range=[1, 6, 2]` 1 being the min value, 6 the maximum and 2 the step. To
-  specify a #GST_TYPE_INT64_RANGE you need to explicitly specify it like:
-  `a-structure, a-int64-range=(gint64) [1, 5]`
-- [GstValueList](GST_TYPE_LIST) are inside "less and greater than" (`&lt;` and
-  `&gt;`). For example `a-structure, list=&lt;1, 2, 3&gt;
-
-Structures are delimited either by a null character `\0` or a semicolumn `;`
-the latter allowing to store multiple structures in the same string (see
-#GstCaps).
-
-Quotes are used as "default" delimiters and can be used around any types that
-don't use other delimiters (for example `a-struct, i=(int)"1"`). They are use
-to allow adding spaces or special characters (such as delimiters,
-semicolumns, etc..) inside strings and you can use backslashes `\` to escape
-characters inside them, for example:
-
-```
-a-struct, special="\"{[(;)]}\" can be used inside quotes"
-```
-
-They also allow for nested structure, such as:
-
-```
-a-struct, nested=(GstStructure)"nested-struct, nested=true"
-```
-
-&gt; *Note*: Be aware that the current #GstCaps / #GstStructure serialization
-&gt; into string has limited support for nested #GstCaps / #GstStructure fields.
-&gt; It can only support one level of nesting. Using more levels will lead to
-&gt; unexpected behavior when using serialization features, such as
-&gt; gst_caps_to_string() or gst_value_serialize() and their counterparts.</doc>

-Variable arguments should be in the form field id quark, field type

-The last variable argument should be %NULL (technically it should be a
-0 quark, but we require %NULL so compilers that support it can check for
-the %NULL terminator and warn if it's not there).
-
-This function is just like gst_structure_get() only that it is slightly

-
-For refcounted (mini)objects you will receive a new reference which

-
-Elements that support changing a stream's metadata will implement this
-interface. Examples of such elements are 'vorbisenc', 'theoraenc' and
-'id3v2mux'.
-
-If you just want to retrieve metadata in your application then all you
-need to do is watch for tag messages on your pipeline's bus. This
-interface is only for setting metadata, not for extracting it. To set tags
-from the application, find tagsetter elements and set tags using e.g.
-gst_tag_setter_merge_tags() or gst_tag_setter_add_tags(). Also consider
-setting the #GstTagMergeMode that is used for tag events that arrive at the
-tagsetter element (default mode is to keep existing tags).
-The application should do that before the element goes to %GST_STATE_PAUSED.
-
-Elements implementing the #GstTagSetter interface often have to merge
-any tags received from upstream and the tags set by the application via
-the interface. This can be done like this:
-
-|[&lt;!-- language="C" --&gt;
-GstTagMergeMode merge_mode;
-const GstTagList *application_tags;
-const GstTagList *event_tags;
-GstTagSetter *tagsetter;
-GstTagList *result;
-
-tagsetter = GST_TAG_SETTER (element);
-
-merge_mode = gst_tag_setter_get_tag_merge_mode (tagsetter);
-application_tags = gst_tag_setter_get_tag_list (tagsetter);
-event_tags = (const GstTagList *) element-&gt;event_tags;
-
-GST_LOG_OBJECT (tagsetter, "merging tags, merge mode = %d", merge_mode);
-GST_LOG_OBJECT (tagsetter, "event tags: %" GST_PTR_FORMAT, event_tags);
-GST_LOG_OBJECT (tagsetter, "set   tags: %" GST_PTR_FORMAT, application_tags);
-
-result = gst_tag_list_merge (application_tags, event_tags, merge_mode);
-
-GST_LOG_OBJECT (tagsetter, "final tags: %" GST_PTR_FORMAT, result);

-threads in a #GstPipeline.
-
-A #GstPad will typically start a #GstTask to push or pull data to/from the
-peer pads. Most source elements start a #GstTask to push data. In some cases
-a demuxer element can start a #GstTask to pull data from a peer element. This
-is typically done when the demuxer can perform random access on the upstream
-peer element for improved performance.
-
-Although convenience functions exist on #GstPad to start/pause/stop tasks, it
-might sometimes be needed to create a #GstTask manually if it is not related to
-a #GstPad.
-
-Before the #GstTask can be run, it needs a #GRecMutex that can be set with
-gst_task_set_lock().
-
-The task can be started, paused and stopped with gst_task_start(), gst_task_pause()
-and gst_task_stop() respectively or with the gst_task_set_state() function.
-
-A #GstTask will repeatedly call the #GstTaskFunction with the user data
-that was provided when creating the task with gst_task_new(). While calling
-the function it will acquire the provided lock. The provided lock is released
-when the task pauses or stops.
-
-Stopping a task with gst_task_stop() will not immediately make sure the task is
-not running anymore. Use gst_task_join() to make sure the task is completely
-stopped and the thread is stopped.
-
-After creating a #GstTask, use gst_object_unref() to free its resources. This can
-only be done when the task is not running anymore.
-
-Task functions can send a #GstMessage to send out-of-band data to the
-application. The application can receive messages from the #GstBus in its
-mainloop.
-
-For debugging purposes, the task will configure its object name as the thread
-name on Linux. Please note that the object name should be configured before the
-task is started; changing the object name after the task has been started, has
-no effect on the thread name.</doc>

-This function will not yet create and start a thread. Use gst_task_start() or

-Also they are used to convert #GstToc into #GstStructure and vice versa.
-
-#GstToc lets you to inform other elements in pipeline or application that playing
-source has some kind of table of contents (TOC). These may be chapters, editions,
-angles or other types. For example: DVD chapters, Matroska chapters or cue sheet
-TOC. Such TOC will be useful for applications to display instead of just a
-playlist.
-
-Using TOC is very easy. Firstly, create #GstToc structure which represents root
-contents of the source. You can also attach TOC-specific tags to it. Then fill
-it with #GstTocEntry entries by appending them to the #GstToc using
-gst_toc_append_entry(), and appending subentries to a #GstTocEntry using
-gst_toc_entry_append_sub_entry().
-
-Note that root level of the TOC can contain only either editions or chapters. You
-should not mix them together at the same level. Otherwise you will get serialization
-/deserialization errors. Make sure that no one of the entries has negative start and
- stop values.
-
-Use gst_event_new_toc() to create a new TOC #GstEvent, and gst_event_parse_toc() to
-parse received TOC event. Use gst_event_new_toc_select() to create a new TOC select #GstEvent,
-and gst_event_parse_toc_select() to parse received TOC select event. The same rule for
-the #GstMessage: gst_message_new_toc() to create new TOC #GstMessage, and
-gst_message_parse_toc() to parse received TOC message.
-
-TOCs can have global scope or current scope. Global scope TOCs contain
-all entries that can possibly be selected using a toc select event, and
-are what an application is usually interested in. TOCs with current scope
-only contain the parts of the TOC relevant to the currently selected/playing
-stream; the current scope TOC is used by downstream elements such as muxers
-to write correct TOC entries when transcoding files, for example. When
-playing a DVD, the global TOC would contain a hierarchy of all titles,
-chapters and angles, for example, while the current TOC would only contain
-the chapters for the currently playing title if playback of a specific
-title was requested.
-
-Applications and plugins should not rely on TOCs having a certain kind of
-structure, but should allow for different alternatives. For example, a
-simple CUE sheet embedded in a file may be presented as a flat list of
-track entries, or could have a top-level edition node (or some other
-alternative type entry) with track entries underneath that node; or even
-multiple top-level edition nodes (or some other alternative type entries)
-each with track entries underneath, in case the source file has extracted
-a track listing from different sources).</doc>

-The way to deal with optional values is to log an additional boolean before
-the optional field, that if %TRUE signals that the optional field is valid

-Hash table returned by this API is a list of "key-value" pairs, and the each
-pair is generated by splitting "URI fragment" per "&amp;" sub-delims, then "key"
-and "value" are split by "=" sub-delims. The "key" returned by this API may
-be undefined keyword by standard.
-A value may be %NULL to indicate that the key should appear in the fragment
-string in the URI, but does not have a value. Free the returned #GHashTable
-with #g_hash_table_unref() when it is no longer required.
-Modifying this hash table does not affect the fragment in the URI.

-
-It's allowed to pass two %NULL pointers to gst_init() in case you don't want
-to pass the command line args to GStreamer.
-
-You can also use GOption to initialize your own parameters as shown in
-the next code fragment:

- };
- ctx = g_option_context_new ("[ADDITIONAL ARGUMENTS]");

-Use gst_version() to query the library version at runtime or use the
-GST_VERSION_* macros to find the version at compile time. Optionally
-gst_version_string() returns a printable string.

-Higher-level elements and applications can programmatically filter
-the ones they are interested in or can recover from,
-and have a default handler handle the rest of them.
-
-The rest of this section will use the term "error"
-to mean both (non-fatal) warnings and (fatal) errors; they are treated
-similarly.
-
-Errors from elements are the combination of a #GError and a debug string.
-The #GError contains:
-- a domain type: CORE, LIBRARY, RESOURCE or STREAM
-- a code: an enum value specific to the domain
-- a translated, human-readable message
-- a non-translated additional debug string, which also contains
-- file and line information
-
-Elements do not have the context required to decide what to do with
-errors.  As such, they should only inform about errors, and stop their
-processing.  In short, an element doesn't know what it is being used for.
-
-It is the application or compound element using the given element that
-has more context about the use of the element. Errors can be received by
-listening to the #GstBus of the element/pipeline for #GstMessage objects with
-the type %GST_MESSAGE_ERROR or %GST_MESSAGE_WARNING. The thrown errors should
-be inspected, and filtered if appropriate.
-
-An application is expected to, by default, present the user with a
-dialog box (or an equivalent) showing the error message.  The dialog
-should also allow a way to get at the additional debug information,
-so the user can provide bug reporting information.
-
-A compound element is expected to forward errors by default higher up
-the hierarchy; this is done by default in the same way as for other types
-of #GstMessage.
-
-When applications or compound elements trigger errors that they can
-recover from, they can filter out these errors and take appropriate action.
-For example, an application that gets an error from xvimagesink
-that indicates all XVideo ports are taken, the application can attempt
-to use another sink instead.
-
-Elements throw errors using the #GST_ELEMENT_ERROR convenience macro:
-
-## Throwing an error
-
-  |[
-    GST_ELEMENT_ERROR (src, RESOURCE, NOT_FOUND,
-      (_("No file name specified for reading.")), (NULL));
-  ]|
-
-Things to keep in mind:
-
-  * Don't go off inventing new error codes.  The ones
-    currently provided should be enough.  If you find your type of error
-    does not fit the current codes, you should use FAILED.
-  * Don't provide a message if the default one suffices.
-    this keeps messages more uniform.  Use (%NULL) - not forgetting the
-    parentheses.
-  * If you do supply a custom message, it should be
-    marked for translation.  The message should start with a capital
-    and end with a period.  The message should describe the error in short,
-    in a human-readable form, and without any complex technical terms.
-    A user interface will present this message as the first thing a user
-    sees.  Details, technical info, ... should go in the debug string.
-
-  * The debug string can be as you like.  Again, use (%NULL)
-    if there's nothing to add - file and line number will still be
-    passed.  #GST_ERROR_SYSTEM can be used as a shortcut to give
-    debug information on a system call error.</doc>

-the application is doing.  It is not meant for programming errors. Use GLib
-methods (g_warning and friends) for that.
-
-The debugging subsystem works only after GStreamer has been initialized
-- for example by calling gst_init().
-
-The debugging subsystem is used to log informational messages while the
-application runs.  Each messages has some properties attached to it. Among
-these properties are the debugging category, the severity (called "level"
-here) and an optional #GObject it belongs to. Each of these messages is sent
-to all registered debugging handlers, which then handle the messages.
-GStreamer attaches a default handler on startup, which outputs requested
-messages to stderr.
-
-Messages are output by using shortcut macros like #GST_DEBUG,
-#GST_CAT_ERROR_OBJECT or similar. These all expand to calling gst_debug_log()
-with the right parameters.
-The only thing a developer will probably want to do is define his own
-categories. This is easily done with 3 lines. At the top of your code,
-declare
-the variables and set the default category.
-|[&lt;!-- language="C" --&gt;
-  GST_DEBUG_CATEGORY_STATIC (my_category);  // define category (statically)
-  #define GST_CAT_DEFAULT my_category       // set as default
-]|
-After that you only need to initialize the category.
-|[&lt;!-- language="C" --&gt;
-  GST_DEBUG_CATEGORY_INIT (my_category, "my category",
-                           0, "This is my very own");
-]|
-Initialization must be done before the category is used first.
-Plugins do this
-in their plugin_init function, libraries and applications should do that
-during their initialization.
-
-The whole debugging subsystem can be disabled at build time with passing the
---disable-gst-debug switch to configure. If this is done, every function,
-macro and even structs described in this file evaluate to default values or
-nothing at all.
-So don't take addresses of these functions or use other tricks.
-If you must do that for some reason, there is still an option.
-If the debugging
-subsystem was compiled out, GST_DISABLE_GST_DEBUG is defined in
-&amp;lt;gst/gst.h&amp;gt;,
-so you can check that before doing your trick.
-Disabling the debugging subsystem will give you a slight (read: unnoticeable)
-speed increase and will reduce the size of your compiled code. The GStreamer
-library itself becomes around 10% smaller.
-
-Please note that there are naming conventions for the names of debugging
-categories. These are explained at GST_DEBUG_CATEGORY_INIT().</doc>

-with that name is already registered, that one is used.
-The old registration may have used a different type however. So don't rely
-on your supplied values.
-
-Important: if you do not supply a merge function the implication will be
-that there can only be one single value for this tag in a tag list and
-any additional values will silently be discarded when being added (unless
-#GST_TAG_MERGE_REPLACE, #GST_TAG_MERGE_REPLACE_ALL, or
-#GST_TAG_MERGE_PREPEND is used as merge mode, in which case the new
-value will replace the old one in the list).
-
-The merge function will be called from gst_tag_list_copy_value() when
-it is required that one or more values for a tag be condensed into
-one single value. This may happen from gst_tag_list_get_string(),
-gst_tag_list_get_int(), gst_tag_list_get_double() etc. What will happen
-exactly in that case depends on how the tag was registered and if a
-merge function was supplied and if so which one.
-
-Two default merge functions are provided: gst_tag_merge_use_first() and
-gst_tag_merge_strings_with_comma().</doc>

-           line="20">Appsink is a sink plugin that supports many different methods for making
-the application get a handle on the GStreamer data in a pipeline. Unlike
-most GStreamer elements, Appsink provides external API functions.
-
-appsink can be used by linking to the gstappsink.h header file to access the
-methods or by using the appsink action signals and properties.
-
-The normal way of retrieving samples from appsink is by using the
-gst_app_sink_pull_sample() and gst_app_sink_pull_preroll() methods.
-These methods block until a sample becomes available in the sink or when the
-sink is shut down or reaches EOS. There are also timed variants of these
-methods, gst_app_sink_try_pull_sample() and gst_app_sink_try_pull_preroll(),
-which accept a timeout parameter to limit the amount of time to wait.
-
-Appsink will internally use a queue to collect buffers from the streaming
-thread. If the application is not pulling samples fast enough, this queue
-will consume a lot of memory over time. The "max-buffers" property can be
-used to limit the queue size. The "drop" property controls whether the
-streaming thread blocks or if older buffers are dropped when the maximum
-queue size is reached. Note that blocking the streaming thread can negatively
-affect real-time performance and should be avoided.
-
-If a blocking behaviour is not desirable, setting the "emit-signals" property
-to %TRUE will make appsink emit the "new-sample" and "new-preroll" signals
-when a sample can be pulled without blocking.
-
-The "caps" property on appsink can be used to control the formats that
-appsink can receive. This property can contain non-fixed caps, the format of
-the pulled samples can be obtained by getting the sample caps.
-
-If one of the pull-preroll or pull-sample methods return %NULL, the appsink
-is stopped or in the EOS state. You can check for the EOS state with the
-"eos" property or with the gst_app_sink_is_eos() method.
-
-The eos signal can also be used to be informed when the EOS state is reached
-to avoid polling.</doc>

-           line="20">The appsrc element can be used by applications to insert data into a
-GStreamer pipeline. Unlike most GStreamer elements, appsrc provides
-external API functions.
-
-appsrc can be used by linking with the libgstapp library to access the
-methods directly or by using the appsrc action signals.
-
-Before operating appsrc, the caps property must be set to fixed caps
-describing the format of the data that will be pushed with appsrc. An
-exception to this is when pushing buffers with unknown caps, in which case no
-caps should be set. This is typically true of file-like sources that push raw
-byte buffers. If you don't want to explicitly set the caps, you can use
-gst_app_src_push_sample. This method gets the caps associated with the
-sample and sets them on the appsrc replacing any previously set caps (if
-different from sample's caps).
-
-The main way of handing data to the appsrc element is by calling the
-gst_app_src_push_buffer() method or by emitting the push-buffer action signal.
-This will put the buffer onto a queue from which appsrc will read from in its
-streaming thread. It is important to note that data transport will not happen
-from the thread that performed the push-buffer call.
-
-The "max-bytes" property controls how much data can be queued in appsrc
-before appsrc considers the queue full. A filled internal queue will always
-signal the "enough-data" signal, which signals the application that it should
-stop pushing data into appsrc. The "block" property will cause appsrc to
-block the push-buffer method until free data becomes available again.
-
-When the internal queue is running out of data, the "need-data" signal is
-emitted, which signals the application that it should start pushing more data
-into appsrc.
-
-In addition to the "need-data" and "enough-data" signals, appsrc can emit the
-"seek-data" signal when the "stream-mode" property is set to "seekable" or
-"random-access". The signal argument will contain the new desired position in
-the stream expressed in the unit set with the "format" property. After
-receiving the seek-data signal, the application should push-buffers from the
-new position.
-
-These signals allow the application to operate the appsrc in two different
-ways:
-
-The push mode, in which the application repeatedly calls the push-buffer/push-sample
-method with a new buffer/sample. Optionally, the queue size in the appsrc
-can be controlled with the enough-data and need-data signals by respectively
-stopping/starting the push-buffer/push-sample calls. This is a typical
-mode of operation for the stream-type "stream" and "seekable". Use this
-mode when implementing various network protocols or hardware devices.
-
-The pull mode, in which the need-data signal triggers the next push-buffer call.
-This mode is typically used in the "random-access" stream-type. Use this
-mode for file access or other randomly accessible sources. In this mode, a
-buffer of exactly the amount of bytes given by the need-data signal should be
-pushed into appsrc.
-
-In all modes, the size property on appsrc should contain the total stream
-size in bytes. Setting this property is mandatory in the random-access mode.
-For the stream and seekable modes, setting this property is optional but
-recommended.
-
-When the application has finished pushing data into appsrc, it should call
-gst_app_src_end_of_stream() or emit the end-of-stream action signal. After
-this call, no more buffers can be pushed into appsrc until a flushing seek
-occurs or the state of the appsrc has gone through READY.</doc>

-their source and sink pads,
-gst_element_class_add_static_pad_template_with_gtype() is a convenient
-helper.
-
-#GstAudioAggregator can perform conversion on the data arriving
-on its sink pads, based on the format expected downstream: in order
-to enable that behaviour, the GType of the sink pads must either be
-a (subclass of) #GstAudioAggregatorConvertPad to use the default
-#GstAudioConverter implementation, or a subclass of #GstAudioAggregatorPad
-implementing #GstAudioAggregatorPadClass.convert_buffer.
-
-To allow for the output caps to change, the mechanism is the same as
-above, with the GType of the source pad.
-
-See #GstAudioMixer for an example.
-
-When conversion is enabled, #GstAudioAggregator will accept
-any type of raw audio caps and perform conversion
-on the data arriving on its sink pads, with whatever downstream
-expects as the target format.
-
-In case downstream caps are not fully fixated, it will use
-the first configured sink pad to finish fixating its source pad
-caps.
-
-A notable exception for now is the sample rate, sink pads must
-have the same sample rate as either the downstream requirement,
-or the first configured pad, or a combination of both (when
-downstream specifies a range or a set of acceptable rates).
-
-The #GstAggregator::samples-selected signal is provided with some
-additional information about the output buffer:
-- "offset"  G_TYPE_UINT64   Offset in samples since segment start
-  for the position that is next to be filled in the output buffer.
-- "frames"  G_TYPE_UINT   Number of frames per output buffer.
-
-In addition the gst_aggregator_peek_next_sample() function returns
-additional information in the info #GstStructure of the returned sample:
-- "output-offset"  G_TYPE_UINT64   Sample offset in output segment relative to
-  the output segment's start where the current position of this input
-  buffer would be placed
-- "position"  G_TYPE_UINT   current position in the input buffer in samples
-- "size"  G_TYPE_UINT   size of the input buffer in samples</doc>

-           line="130">This function is set with gst_audio_base_sink_set_custom_slaving_callback()
-and is called during playback. It receives the current time of external and
-internal clocks, which the callback can then use to apply any custom
-slaving/synchronization schemes.
-
-The external clock is the sink's element clock, the internal one is the
-internal audio clock. The internal audio clock's calibration is applied to
-the timestamps before they are passed to the callback. The difference between
-etime and itime is the skew; how much internal and external clock lie apart
-from each other. A skew of 0 means both clocks are perfectly in sync.
-itime &gt; etime means the external clock is going slower, while itime &lt; etime
-means it is going faster than the internal clock. etime and itime are always
-valid timestamps, except for when a discontinuity happens.
-
-requested_skew is an output value the callback can write to. It informs the
-sink of whether or not it should move the playout pointer, and if so, by how
-much. This pointer is only NULL if a discontinuity occurs; otherwise, it is
-safe to write to *requested_skew. The default skew is 0.
-
-The sink may experience discontinuities. If one happens, discont is TRUE,
-itime, etime are set to GST_CLOCK_TIME_NONE, and requested_skew is NULL.
-This makes it possible to reset custom clock slaving algorithms when a
-discontinuity happens.</doc>

-result of the map operation in @buffer.
-
-This is especially useful when the @gstbuffer is in non-interleaved (planar)
-layout, in which case this function will use the information in the
-@gstbuffer's attached #GstAudioMeta in order to map each channel in a
-separate "plane" in #GstAudioBuffer. If a #GstAudioMeta is not attached
-on the @gstbuffer, then it must be in interleaved layout.
-
-If a #GstAudioMeta is attached, then the #GstAudioInfo on the meta is checked
-against @info. Normally, they should be equal, but in case they are not,
-a g_critical will be printed and the #GstAudioInfo from the meta will be
-used.
-
-In non-interleaved buffers, it is possible to have each channel on a separate
-#GstMemory. In this case, each memory will be mapped separately to avoid
-copying their contents in a larger memory area. Do note though that it is
-not supported to have a single channel spanning over two or more different
-#GstMemory objects. Although the map operation will likely succeed in this
-case, it will be highly sub-optimal and it is recommended to merge all the
-memories in the buffer before calling this function.
-
-Note: The actual #GstBuffer is not ref'ed, but it is required to stay valid
-as long as it's mapped.</doc>

-things like seeking, querying, discid calculation, tags, and buffer
-timestamping.
-
-## Using GstAudioCdSrc-based elements in applications
-
-GstAudioCdSrc registers two #GstFormat&lt;!-- --&gt;s of its own, namely
-the "track" format and the "sector" format. Applications will usually
-only find the "track" format interesting. You can retrieve that #GstFormat
-for use in seek events or queries with gst_format_get_by_nick("track").
-
-In order to query the number of tracks, for example, an application would
-set the CDDA source element to READY or PAUSED state and then query the
-the number of tracks via gst_element_query_duration() using the track
-format acquired above. Applications can query the currently playing track
-in the same way.
-
-Alternatively, applications may retrieve the currently playing track and
-the total number of tracks from the taglist that will posted on the bus
-whenever the CD is opened or the currently playing track changes. The
-taglist will contain GST_TAG_TRACK_NUMBER and GST_TAG_TRACK_COUNT tags.
-
-Applications playing back CD audio using playbin and cdda://n URIs should
-issue a seek command in track format to change between tracks, rather than
-setting a new cdda://n+1 URI on playbin (as setting a new URI on playbin
-involves closing and re-opening the CD device, which is much much slower).
-
-## Tags and meta-information
-
-CDDA sources will automatically emit a number of tags, details about which
-can be found in the libgsttag documentation. Those tags are:
-#GST_TAG_CDDA_CDDB_DISCID, #GST_TAG_CDDA_CDDB_DISCID_FULL,
-#GST_TAG_CDDA_MUSICBRAINZ_DISCID, #GST_TAG_CDDA_MUSICBRAINZ_DISCID_FULL,
-among others.
-
-## Tracks and Table of Contents (TOC)
-
-Applications will be informed of the available tracks via a TOC message
-on the pipeline's #GstBus. The #GstToc will contain a #GstTocEntry for
-each track, with information about each track. The duration for each
-track can be retrieved via the #GST_TAG_DURATION tag from each entry's
-tag list, or calculated via gst_toc_entry_get_start_stop_times().
-The track entries in the TOC will be sorted by track number.</doc>

-These are the channels defined in SMPTE 2036-2-2008
-Table 1 for 22.2 audio systems with the Surround and Wide channels from
-DTS Coherent Acoustics (v.1.3.1) and 10.2 and 7.1 layouts. In the caps the
-actual channel layout is expressed with a channel count and a channel mask,
-which describes the existing channels. The positions in the bit mask correspond
-to the enum values.
-For negotiation it is allowed to have more bits set in the channel mask than
-the number of channels to specify the allowed channel positions but this is
-not allowed in negotiated caps. It is not allowed in any situation other
-than the one mentioned below to have less bits set in the channel mask than
-the number of channels.
-
-@GST_AUDIO_CHANNEL_POSITION_MONO can only be used with a single mono channel that
-has no direction information and would be mixed into all directional channels.
-This is expressed in caps by having a single channel and no channel mask.
-
-@GST_AUDIO_CHANNEL_POSITION_NONE can only be used if all channels have this position.
-This is expressed in caps by having a channel mask with no bits set.
-
-As another special case it is allowed to have two channels without a channel mask.
-This implicitly means that this is a stereo stream with a front left and front right
-channel.</doc>

-raw audio samples.
-
-GstAudioDecoder and subclass should cooperate as follows.
-
-## Configuration
-
-  * Initially, GstAudioDecoder calls @start when the decoder element
-    is activated, which allows subclass to perform any global setup.
-    Base class (context) parameters can already be set according to subclass
-    capabilities (or possibly upon receive more information in subsequent
-    @set_format).
-  * GstAudioDecoder calls @set_format to inform subclass of the format
-    of input audio data that it is about to receive.
-    While unlikely, it might be called more than once, if changing input
-    parameters require reconfiguration.
-  * GstAudioDecoder calls @stop at end of all processing.
-
-As of configuration stage, and throughout processing, GstAudioDecoder
-provides various (context) parameters, e.g. describing the format of
-output audio data (valid when output caps have been set) or current parsing state.
-Conversely, subclass can and should configure context to inform
-base class of its expectation w.r.t. buffer handling.
-
-## Data processing
-    * Base class gathers input data, and optionally allows subclass
-      to parse this into subsequently manageable (as defined by subclass)
-      chunks.  Such chunks are subsequently referred to as 'frames',
-      though they may or may not correspond to 1 (or more) audio format frame.
-    * Input frame is provided to subclass' @handle_frame.
-    * If codec processing results in decoded data, subclass should call
-      @gst_audio_decoder_finish_frame to have decoded data pushed
-      downstream.
-    * Just prior to actually pushing a buffer downstream,
-      it is passed to @pre_push.  Subclass should either use this callback
-      to arrange for additional downstream pushing or otherwise ensure such
-      custom pushing occurs after at least a method call has finished since
-      setting src pad caps.
-    * During the parsing process GstAudioDecoderClass will handle both
-      srcpad and sinkpad events. Sink events will be passed to subclass
-      if @event callback has been provided.
-
-## Shutdown phase
-
-  * GstAudioDecoder class calls @stop to inform the subclass that data
-    parsing will be stopped.
-
-Subclass is responsible for providing pad template caps for
-source and sink pads. The pads need to be named "sink" and "src". It also
-needs to set the fixed caps on srcpad, when the format is ensured.  This
-is typically when base class calls subclass' @set_format function, though
-it might be delayed until calling @gst_audio_decoder_finish_frame.
-
-In summary, above process should have subclass concentrating on
-codec data processing while leaving other matters to base class,
-such as most notably timestamp handling.  While it may exert more control
-in this area (see e.g. @pre_push), it is very much not recommended.
-
-In particular, base class will try to arrange for perfect output timestamps
-as much as possible while tracking upstream timestamps.
-To this end, if deviation between the next ideal expected perfect timestamp
-and upstream exceeds #GstAudioDecoder:tolerance, then resync to upstream
-occurs (which would happen always if the tolerance mechanism is disabled).
-
-In non-live pipelines, baseclass can also (configurably) arrange for
-output buffer aggregation which may help to redue large(r) numbers of
-small(er) buffers being pushed and processed downstream. Note that this
-feature is only available if the buffer layout is interleaved. For planar
-buffers, the decoder implementation is fully responsible for the output
-buffer size.
-
-On the other hand, it should be noted that baseclass only provides limited
-seeking support (upon explicit subclass request), as full-fledged support
-should rather be left to upstream demuxer, parser or alike.  This simple
-approach caters for seeking and duration reporting using estimated input
-bitrates.
-
-Things that subclass need to take care of:
-
-  * Provide pad templates
-  * Set source pad caps when appropriate
-  * Set user-configurable properties to sane defaults for format and
-     implementing codec at hand, and convey some subclass capabilities and
-     expectations in context.
-
-  * Accept data in @handle_frame and provide encoded results to
-     @gst_audio_decoder_finish_frame.  If it is prepared to perform
-     PLC, it should also accept NULL data in @handle_frame and provide for
-     data for indicated duration.</doc>

-encoded audio data.
-
-GstAudioEncoder and subclass should cooperate as follows.
-
-## Configuration
-
-  * Initially, GstAudioEncoder calls @start when the encoder element
-    is activated, which allows subclass to perform any global setup.
-
-  * GstAudioEncoder calls @set_format to inform subclass of the format
-    of input audio data that it is about to receive.  Subclass should
-    setup for encoding and configure various base class parameters
-    appropriately, notably those directing desired input data handling.
-    While unlikely, it might be called more than once, if changing input
-    parameters require reconfiguration.
-
-  * GstAudioEncoder calls @stop at end of all processing.
-
-As of configuration stage, and throughout processing, GstAudioEncoder
-maintains various parameters that provide required context,
-e.g. describing the format of input audio data.
-Conversely, subclass can and should configure these context parameters
-to inform base class of its expectation w.r.t. buffer handling.
-
-## Data processing
-
-    * Base class gathers input sample data (as directed by the context's
-      frame_samples and frame_max) and provides this to subclass' @handle_frame.
-    * If codec processing results in encoded data, subclass should call
-      gst_audio_encoder_finish_frame() to have encoded data pushed
-      downstream. Alternatively, it might also call
-      gst_audio_encoder_finish_frame() (with a NULL buffer and some number of
-      dropped samples) to indicate dropped (non-encoded) samples.
-    * Just prior to actually pushing a buffer downstream,
-      it is passed to @pre_push.
-    * During the parsing process GstAudioEncoderClass will handle both
-      srcpad and sinkpad events. Sink events will be passed to subclass
-      if @event callback has been provided.
-
-## Shutdown phase
-
-  * GstAudioEncoder class calls @stop to inform the subclass that data
-    parsing will be stopped.
-
-Subclass is responsible for providing pad template caps for
-source and sink pads. The pads need to be named "sink" and "src". It also
-needs to set the fixed caps on srcpad, when the format is ensured.  This
-is typically when base class calls subclass' @set_format function, though
-it might be delayed until calling @gst_audio_encoder_finish_frame.
-
-In summary, above process should have subclass concentrating on
-codec data processing while leaving other matters to base class,
-such as most notably timestamp handling.  While it may exert more control
-in this area (see e.g. @pre_push), it is very much not recommended.
-
-In particular, base class will either favor tracking upstream timestamps
-(at the possible expense of jitter) or aim to arrange for a perfect stream of
-output timestamps, depending on #GstAudioEncoder:perfect-timestamp.
-However, in the latter case, the input may not be so perfect or ideal, which
-is handled as follows.  An input timestamp is compared with the expected
-timestamp as dictated by input sample stream and if the deviation is less
-than #GstAudioEncoder:tolerance, the deviation is discarded.
-Otherwise, it is considered a discontuinity and subsequent output timestamp
-is resynced to the new position after performing configured discontinuity
-processing.  In the non-perfect-timestamp case, an upstream variation
-exceeding tolerance only leads to marking DISCONT on subsequent outgoing
-(while timestamps are adjusted to upstream regardless of variation).
-While DISCONT is also marked in the perfect-timestamp case, this one
-optionally (see #GstAudioEncoder:hard-resync)
-performs some additional steps, such as clipping of (early) input samples
-or draining all currently remaining input data, depending on the direction
-of the discontuinity.
-
-If perfect timestamps are arranged, it is also possible to request baseclass
-(usually set by subclass) to provide additional buffer metadata (in OFFSET
-and OFFSET_END) fields according to granule defined semantics currently
-needed by oggmux.  Specifically, OFFSET is set to granulepos (= sample count
-including buffer) and OFFSET_END to corresponding timestamp (as determined
-by same sample count and sample rate).
-
-Things that subclass need to take care of:
-
-  * Provide pad templates
-  * Set source pad caps when appropriate
-  * Inform base class of buffer processing needs using context's
-     frame_samples and frame_bytes.
-  * Set user-configurable properties to sane defaults for format and
-     implementing codec at hand, e.g. those controlling timestamp behaviour
-     and discontinuity processing.
-  * Accept data in @handle_frame and provide encoded results to
-     gst_audio_encoder_finish_frame().</doc>

-
-@in_samples and @out_samples define the rate conversion to perform on the
-samples in @data. For negative rates, @out_samples must be negative and
-@in_samples positive.
-
-When @out_samples is positive, the first sample will be written at position @sample
-in the ringbuffer. When @out_samples is negative, the last sample will be written to
-@sample in reverse order.
-
-@out_samples does not need to be a multiple of the segment size of the ringbuffer
-although it is recommended for optimal performance.
-
-@accum will hold a temporary accumulator used in rate conversion and should be
-set to 0 when this function is first called. In case the commit operation is
-interrupted, one can resume the processing by passing the previously returned
-@accum value back to this function.

-subclasses to implement a set of simple functions:
-
-* `open()` :Open the device.
-
-* `prepare()` :Configure the device with the specified format.
-
-* `write()` :Write samples to the device.
-
-* `reset()` :Unblock writes and flush the device.
-
-* `delay()` :Get the number of samples written but not yet played
-by the device.
-
-* `unprepare()` :Undo operations done by prepare.
-
-* `close()` :Close the device.
-
-All scheduling of samples and timestamps is done in this base class
-together with #GstAudioBaseSink using a default implementation of a
-#GstAudioRingBuffer that uses threads.</doc>

-
-* `open()` :Open the device.
-* `prepare()` :Configure the device with the specified format.
-* `read()` :Read samples from the device.
-* `reset()` :Unblock reads and flush the device.
-* `delay()` :Get the number of samples in the device but not yet read.
-* `unprepare()` :Undo operations done by prepare.
-* `close()` :Close the device.

-
-Applications can use this interface to get or set the current stream volume. For this
-the "volume" #GObject property can be used or the helper functions gst_stream_volume_set_volume()
-and gst_stream_volume_get_volume(). This volume is always a linear factor, i.e. 0.0 is muted
-1.0 is 100%. For showing the volume in a GUI it might make sense to convert it to
-a different format by using gst_stream_volume_convert_volume(). Volume sliders should usually
-use a cubic volume.
-
-Separate from the volume the stream can also be muted by the "mute" #GObject property or
-gst_stream_volume_set_mute() and gst_stream_volume_get_mute().
-
-Elements that provide some kind of stream volume should implement the "volume" and
-"mute" #GObject properties and handle setting and getting of them properly.
-The volume property is defined to be a linear volume factor.</doc>

-While for example raw video contains one image per buffer, the same is not
-true for a lot of other formats, especially those that come directly from
-a file. So if you have undefined buffer sizes and require a specific size,
-this object is for you.
-
-An adapter is created with gst_adapter_new(). It can be freed again with
-g_object_unref().
-
-The theory of operation is like this: All buffers received are put
-into the adapter using gst_adapter_push() and the data is then read back
-in chunks of the desired size using gst_adapter_map()/gst_adapter_unmap()
-and/or gst_adapter_copy(). After the data has been processed, it is freed
-using gst_adapter_unmap().
-
-Other methods such as gst_adapter_take() and gst_adapter_take_buffer()
-combine gst_adapter_map() and gst_adapter_unmap() in one method and are
-potentially more convenient for some use cases.
-
-For example, a sink pad's chain function that needs to pass data to a library
-in 512-byte chunks could be implemented like this:
-|[&lt;!-- language="C" --&gt;
-static GstFlowReturn
-sink_pad_chain (GstPad *pad, GstObject *parent, GstBuffer *buffer)
-{
-  MyElement *this;
-  GstAdapter *adapter;
-  GstFlowReturn ret = GST_FLOW_OK;
-
-  this = MY_ELEMENT (parent);
-
-  adapter = this-&gt;adapter;
-
-  // put buffer into adapter
-  gst_adapter_push (adapter, buffer);
-
-  // while we can read out 512 bytes, process them
-  while (gst_adapter_available (adapter) &gt;= 512 &amp;&amp; ret == GST_FLOW_OK) {
-    const guint8 *data = gst_adapter_map (adapter, 512);
-    // use flowreturn as an error value
-    ret = my_library_foo (data);
-    gst_adapter_unmap (adapter);
-    gst_adapter_flush (adapter, 512);
-  }
-  return ret;
-}
-]|
-
-For another example, a simple element inside GStreamer that uses #GstAdapter
-is the libvisual element.
-
-An element using #GstAdapter in its sink pad chain function should ensure that
-when the FLUSH_STOP event is received, that any queued data is cleared using
-gst_adapter_clear(). Data should also be cleared or processed on EOS and
-when changing state from %GST_STATE_PAUSED to %GST_STATE_READY.
-
-Also check the GST_BUFFER_FLAG_DISCONT flag on the buffer. Some elements might
-need to clear the adapter after a discontinuity.
-
-The adapter will keep track of the timestamps of the buffers
-that were pushed. The last seen timestamp before the current position
-can be queried with gst_adapter_prev_pts(). This function can
-optionally return the number of bytes between the start of the buffer that
-carried the timestamp and the current adapter position. The distance is
-useful when dealing with, for example, raw audio samples because it allows
-you to calculate the timestamp of the current adapter position by using the
-last seen timestamp and the amount of bytes since.  Additionally, the
-gst_adapter_prev_pts_at_offset() can be used to determine the last
-seen timestamp at a particular offset in the adapter.
-
-The adapter will also keep track of the offset of the buffers
-(#GST_BUFFER_OFFSET) that were pushed. The last seen offset before the
-current position can be queried with gst_adapter_prev_offset(). This function
-can optionally return the number of bytes between the start of the buffer
-that carried the offset and the current adapter position.
-
-Additionally the adapter also keeps track of the PTS, DTS and buffer offset
-at the last discontinuity, which can be retrieved with
-gst_adapter_pts_at_discont(), gst_adapter_dts_at_discont() and
-gst_adapter_offset_at_discont(). The number of bytes that were consumed
-since then can be queried with gst_adapter_distance_from_discont().
-
-A last thing to note is that while #GstAdapter is pretty optimized,
-merging buffers still might be an operation that requires a `malloc()` and
-`memcpy()` operation, and these operations are not the fastest. Because of
-this, some functions like gst_adapter_available_fast() are provided to help
-speed up such cases should you want to. To avoid repeated memory allocations,
-gst_adapter_copy() can be used to copy data into a (statically allocated)
-user provided buffer.
-
-#GstAdapter is not MT safe. All operations on an adapter must be serialized by
-the caller. This is not normally a problem, however, as the normal use case
-of #GstAdapter is inside one pad's chain function, in which case access is
-serialized via the pad's STREAM_LOCK.
-
-Note that gst_adapter_push() takes ownership of the buffer passed. Use
-gst_buffer_ref() before pushing it into the adapter if you still want to
-access the buffer later. The adapter will never modify the data in the
-buffer pushed in it.</doc>

-   #GstAggregatorClass.sink_event() and #GstAggregatorClass.sink_query() as
-   needed.
-
- * When data is queued on all pads, the aggregate vmethod is called.
-
- * One can peek at the data on any given GstAggregatorPad with the
-   gst_aggregator_pad_peek_buffer() method, and remove it from the pad
-   with the gst_aggregator_pad_pop_buffer () method. When a buffer
-   has been taken with pop_buffer (), a new buffer can be queued
-   on that pad.
-
- * When gst_aggregator_pad_peek_buffer() or gst_aggregator_pad_has_buffer()
-   are called, a reference is taken to the returned buffer, which stays
-   valid until either:
-
-     - gst_aggregator_pad_pop_buffer() is called, in which case the caller
-       is guaranteed that the buffer they receive is the same as the peeked
-       buffer.
-     - gst_aggregator_pad_drop_buffer() is called, in which case the caller
-       is guaranteed that the dropped buffer is the one that was peeked.
-     - the subclass implementation of #GstAggregatorClass.aggregate returns.
-
-   Subsequent calls to gst_aggregator_pad_peek_buffer() or
-   gst_aggregator_pad_has_buffer() return / check the same buffer that was
-   returned / checked, until one of the conditions listed above is met.
-
-   Subclasses are only allowed to call these methods from the aggregate
-   thread.
-
- * If the subclass wishes to push a buffer downstream in its aggregate
-   implementation, it should do so through the
-   gst_aggregator_finish_buffer() method. This method will take care
-   of sending and ordering mandatory events such as stream start, caps
-   and segment. Buffer lists can also be pushed out with
-   gst_aggregator_finish_buffer_list().
-
- * Same goes for EOS events, which should not be pushed directly by the
-   subclass, it should instead return GST_FLOW_EOS in its aggregate
-   implementation.
-
- * Note that the aggregator logic regarding gap event handling is to turn
-   these into gap buffers with matching PTS and duration. It will also
-   flag these buffers with GST_BUFFER_FLAG_GAP and GST_BUFFER_FLAG_DROPPABLE
-   to ease their identification and subsequent processing.
-
- * Subclasses must use (a subclass of) #GstAggregatorPad for both their
-   sink and source pads.
-   See gst_element_class_add_static_pad_template_with_gtype().

-
-It provides for:
-
-  * provides one sink pad and one source pad
-  * handles state changes
-  * can operate in pull mode or push mode
-  * handles seeking in both modes
-  * handles events (SEGMENT/EOS/FLUSH)
-  * handles queries (POSITION/DURATION/SEEKING/FORMAT/CONVERT)
-  * handles flushing
-
-The purpose of this base class is to provide the basic functionality of
-a parser and share a lot of rather complex code.
-
-# Description of the parsing mechanism:
-
-## Set-up phase
-
- * #GstBaseParse calls #GstBaseParseClass.start() to inform subclass
-   that data processing is about to start now.
-
- * #GstBaseParse class calls #GstBaseParseClass.set_sink_caps() to
-   inform the subclass about incoming sinkpad caps. Subclass could
-   already set the srcpad caps accordingly, but this might be delayed
-   until calling gst_base_parse_finish_frame() with a non-queued frame.
-
- * At least at this point subclass needs to tell the #GstBaseParse class
-   how big data chunks it wants to receive (minimum frame size ). It can
-   do this with gst_base_parse_set_min_frame_size().
-
- * #GstBaseParse class sets up appropriate data passing mode (pull/push)
-   and starts to process the data.
-
-## Parsing phase
-
- * #GstBaseParse gathers at least min_frame_size bytes of data either
-   by pulling it from upstream or collecting buffers in an internal
-   #GstAdapter.
-
- * A buffer of (at least) min_frame_size bytes is passed to subclass
-   with #GstBaseParseClass.handle_frame(). Subclass checks the contents
-   and can optionally return #GST_FLOW_OK along with an amount of data
-   to be skipped to find a valid frame (which will result in a
-   subsequent DISCONT).  If, otherwise, the buffer does not hold a
-   complete frame, #GstBaseParseClass.handle_frame() can merely return
-   and will be called again when additional data is available.  In push
-   mode this amounts to an additional input buffer (thus minimal
-   additional latency), in pull mode this amounts to some arbitrary
-   reasonable buffer size increase.
-
-   Of course, gst_base_parse_set_min_frame_size() could also be used if
-   a very specific known amount of additional data is required.  If,
-   however, the buffer holds a complete valid frame, it can pass the
-   size of this frame to gst_base_parse_finish_frame().
-
-   If acting as a converter, it can also merely indicate consumed input
-   data while simultaneously providing custom output data.  Note that
-   baseclass performs some processing (such as tracking overall consumed
-   data rate versus duration) for each finished frame, but other state
-   is only updated upon each call to #GstBaseParseClass.handle_frame()
-   (such as tracking upstream input timestamp).
-
-   Subclass is also responsible for setting the buffer metadata
-   (e.g. buffer timestamp and duration, or keyframe if applicable).
-   (although the latter can also be done by #GstBaseParse if it is
-   appropriately configured, see below).  Frame is provided with
-   timestamp derived from upstream (as much as generally possible),
-   duration obtained from configuration (see below), and offset
-   if meaningful (in pull mode).
-
-   Note that #GstBaseParseClass.handle_frame() might receive any small
-   amount of input data when leftover data is being drained (e.g. at
-   EOS).
-
- * As part of finish frame processing, just prior to actually pushing
-   the buffer in question, it is passed to
-   #GstBaseParseClass.pre_push_frame() which gives subclass yet one last
-   chance to examine buffer metadata, or to send some custom (tag)
-   events, or to perform custom (segment) filtering.
-
- * During the parsing process #GstBaseParseClass will handle both srcpad
-   and sinkpad events. They will be passed to subclass if
-   #GstBaseParseClass.sink_event() or #GstBaseParseClass.src_event()
-   implementations have been provided.
-
-## Shutdown phase
-
-* #GstBaseParse class calls #GstBaseParseClass.stop() to inform the
-  subclass that data parsing will be stopped.
-
-Subclass is responsible for providing pad template caps for source and
-sink pads. The pads need to be named "sink" and "src". It also needs to
-set the fixed caps on srcpad, when the format is ensured (e.g.  when
-base class calls subclass' #GstBaseParseClass.set_sink_caps() function).
-
-This base class uses %GST_FORMAT_DEFAULT as a meaning of frames. So,
-subclass conversion routine needs to know that conversion from
-%GST_FORMAT_TIME to %GST_FORMAT_DEFAULT must return the
-frame number that can be found from the given byte position.
-
-#GstBaseParse uses subclasses conversion methods also for seeking (or
-otherwise uses its own default one, see also below).
-
-Subclass @start and @stop functions will be called to inform the beginning
-and end of data processing.
-
-Things that subclass need to take care of:
-
-* Provide pad templates
-* Fixate the source pad caps when appropriate
-* Inform base class how big data chunks should be retrieved. This is
-  done with gst_base_parse_set_min_frame_size() function.
-* Examine data chunks passed to subclass with
-  #GstBaseParseClass.handle_frame() and pass proper frame(s) to
-  gst_base_parse_finish_frame(), and setting src pad caps and timestamps
-  on frame.
-* Provide conversion functions
-* Update the duration information with gst_base_parse_set_duration()
-* Optionally passthrough using gst_base_parse_set_passthrough()
-* Configure various baseparse parameters using
-  gst_base_parse_set_average_bitrate(), gst_base_parse_set_syncable()
-  and gst_base_parse_set_frame_rate().
-
-* In particular, if subclass is unable to determine a duration, but
-  parsing (or specs) yields a frames per seconds rate, then this can be
-  provided to #GstBaseParse to enable it to cater for buffer time
-  metadata (which will be taken from upstream as much as
-  possible). Internally keeping track of frame durations and respective
-  sizes that have been pushed provides #GstBaseParse with an estimated
-  bitrate. A default #GstBaseParseClass.convert() (used if not
-  overridden) will then use these rates to perform obvious conversions.
-  These rates are also used to update (estimated) duration at regular
-  frame intervals.</doc>

-cases, the correct timestamps will occur in the stream after the
-start of the frame, but before the start of the actual picture data.
-This function can be used to set the timestamps based on the offset
-into the frame data that the picture starts.</doc>

-           line="22">#GstBaseSink is the base class for sink elements in GStreamer, such as
-xvimagesink or filesink. It is a layer on top of #GstElement that provides a
-simplified interface to plugin writers. #GstBaseSink handles many details
-for you, for example: preroll, clock synchronization, state changes,
-activation in push or pull mode, and queries.
-
-In most cases, when writing sink elements, there is no need to implement
-class methods from #GstElement or to set functions on pads, because the
-#GstBaseSink infrastructure should be sufficient.
-
-#GstBaseSink provides support for exactly one sink pad, which should be
-named "sink". A sink implementation (subclass of #GstBaseSink) should
-install a pad template in its class_init function, like so:
-|[&lt;!-- language="C" --&gt;
-static void
-my_element_class_init (GstMyElementClass *klass)
-{
-  GstElementClass *gstelement_class = GST_ELEMENT_CLASS (klass);
-
-  // sinktemplate should be a #GstStaticPadTemplate with direction
-  // %GST_PAD_SINK and name "sink"
-  gst_element_class_add_static_pad_template (gstelement_class, &amp;amp;sinktemplate);
-
-  gst_element_class_set_static_metadata (gstelement_class,
-      "Sink name",
-      "Sink",
-      "My Sink element",
-      "The author &lt;my.sink@my.email&gt;");
-}
-]|
-
-#GstBaseSink will handle the prerolling correctly. This means that it will
-return %GST_STATE_CHANGE_ASYNC from a state change to PAUSED until the first
-buffer arrives in this element. The base class will call the
-#GstBaseSinkClass.preroll() vmethod with this preroll buffer and will then
-commit the state change to the next asynchronously pending state.
-
-When the element is set to PLAYING, #GstBaseSink will synchronise on the
-clock using the times returned from #GstBaseSinkClass.get_times(). If this
-function returns %GST_CLOCK_TIME_NONE for the start time, no synchronisation
-will be done. Synchronisation can be disabled entirely by setting the object
-#GstBaseSink:sync property to %FALSE.
-
-After synchronisation the virtual method #GstBaseSinkClass.render() will be
-called. Subclasses should minimally implement this method.
-
-Subclasses that synchronise on the clock in the #GstBaseSinkClass.render()
-method are supported as well. These classes typically receive a buffer in
-the render method and can then potentially block on the clock while
-rendering. A typical example is an audiosink.
-These subclasses can use gst_base_sink_wait_preroll() to perform the
-blocking wait.
-
-Upon receiving the EOS event in the PLAYING state, #GstBaseSink will wait
-for the clock to reach the time indicated by the stop time of the last
-#GstBaseSinkClass.get_times() call before posting an EOS message. When the
-element receives EOS in PAUSED, preroll completes, the event is queued and an
-EOS message is posted when going to PLAYING.
-
-#GstBaseSink will internally use the %GST_EVENT_SEGMENT events to schedule
-synchronisation and clipping of buffers. Buffers that fall completely outside
-of the current segment are dropped. Buffers that fall partially in the
-segment are rendered (and prerolled). Subclasses should do any subbuffer
-clipping themselves when needed.
-
-#GstBaseSink will by default report the current playback position in
-%GST_FORMAT_TIME based on the current clock time and segment information.
-If no clock has been set on the element, the query will be forwarded
-upstream.
-
-The #GstBaseSinkClass.set_caps() function will be called when the subclass
-should configure itself to process a specific media type.
-
-The #GstBaseSinkClass.start() and #GstBaseSinkClass.stop() virtual methods
-will be called when resources should be allocated. Any
-#GstBaseSinkClass.preroll(), #GstBaseSinkClass.render() and
-#GstBaseSinkClass.set_caps() function will be called between the
-#GstBaseSinkClass.start() and #GstBaseSinkClass.stop() calls.
-
-The #GstBaseSinkClass.event() virtual method will be called when an event is
-received by #GstBaseSink. Normally this method should only be overridden by
-very specific elements (such as file sinks) which need to handle the
-newsegment event specially.
-
-The #GstBaseSinkClass.unlock() method is called when the elements should
-unblock any blocking operations they perform in the
-#GstBaseSinkClass.render() method. This is mostly useful when the
-#GstBaseSinkClass.render() method performs a blocking write on a file
-descriptor, for example.
-
-The #GstBaseSink:max-lateness property affects how the sink deals with
-buffers that arrive too late in the sink. A buffer arrives too late in the
-sink when the presentation time (as a combination of the last segment, buffer
-timestamp and element base_time) plus the duration is before the current
-time of the clock.
-If the frame is later than max-lateness, the sink will drop the buffer
-without calling the render method.
-This feature is disabled if sync is disabled, the
-#GstBaseSinkClass.get_times() method does not return a valid start time or
-max-lateness is set to -1 (the default).
-Subclasses can use gst_base_sink_set_max_lateness() to configure the
-max-lateness value.
-
-The #GstBaseSink:qos property will enable the quality-of-service features of
-the basesink which gather statistics about the real-time performance of the
-clock synchronisation. For each buffer received in the sink, statistics are
-gathered and a QOS event is sent upstream with these numbers. This
-information can then be used by upstream elements to reduce their processing
-rate, for example.
-
-The #GstBaseSink:async property can be used to instruct the sink to never
-perform an ASYNC state change. This feature is mostly usable when dealing
-with non-synchronized streams or sparse streams.</doc>

-           line="23">This is a generic base class for source elements. The following
-types of sources are supported:
-
-  * random access sources like files
-  * seekable sources
-  * live sources
-
-The source can be configured to operate in any #GstFormat with the
-gst_base_src_set_format() method. The currently set format determines
-the format of the internal #GstSegment and any %GST_EVENT_SEGMENT
-events. The default format for #GstBaseSrc is %GST_FORMAT_BYTES.
-
-#GstBaseSrc always supports push mode scheduling. If the following
-conditions are met, it also supports pull mode scheduling:
-
-  * The format is set to %GST_FORMAT_BYTES (default).
-  * #GstBaseSrcClass.is_seekable() returns %TRUE.
-
-If all the conditions are met for operating in pull mode, #GstBaseSrc is
-automatically seekable in push mode as well. The following conditions must
-be met to make the element seekable in push mode when the format is not
-%GST_FORMAT_BYTES:
-
-* #GstBaseSrcClass.is_seekable() returns %TRUE.
-* #GstBaseSrcClass.query() can convert all supported seek formats to the
-  internal format as set with gst_base_src_set_format().
-* #GstBaseSrcClass.do_seek() is implemented, performs the seek and returns
-   %TRUE.
-
-When the element does not meet the requirements to operate in pull mode, the
-offset and length in the #GstBaseSrcClass.create() method should be ignored.
-It is recommended to subclass #GstPushSrc instead, in this situation. If the
-element can operate in pull mode but only with specific offsets and
-lengths, it is allowed to generate an error when the wrong values are passed
-to the #GstBaseSrcClass.create() function.
-
-#GstBaseSrc has support for live sources. Live sources are sources that when
-paused discard data, such as audio or video capture devices. A typical live
-source also produces data at a fixed rate and thus provides a clock to publish
-this rate.
-Use gst_base_src_set_live() to activate the live source mode.
-
-A live source does not produce data in the PAUSED state. This means that the
-#GstBaseSrcClass.create() method will not be called in PAUSED but only in
-PLAYING. To signal the pipeline that the element will not produce data, the
-return value from the READY to PAUSED state will be
-%GST_STATE_CHANGE_NO_PREROLL.
-
-A typical live source will timestamp the buffers it creates with the
-current running time of the pipeline. This is one reason why a live source
-can only produce data in the PLAYING state, when the clock is actually
-distributed and running.
-
-Live sources that synchronize and block on the clock (an audio source, for
-example) can use gst_base_src_wait_playing() when the
-#GstBaseSrcClass.create() function was interrupted by a state change to
-PAUSED.
-
-The #GstBaseSrcClass.get_times() method can be used to implement pseudo-live
-sources. It only makes sense to implement the #GstBaseSrcClass.get_times()
-function if the source is a live source. The #GstBaseSrcClass.get_times()
-function should return timestamps starting from 0, as if it were a non-live
-source. The base class will make sure that the timestamps are transformed
-into the current running_time. The base source will then wait for the
-calculated running_time before pushing out the buffer.
-
-For live sources, the base class will by default report a latency of 0.
-For pseudo live sources, the base class will by default measure the difference
-between the first buffer timestamp and the start time of get_times and will
-report this value as the latency.
-Subclasses should override the query function when this behaviour is not
-acceptable.
-
-There is only support in #GstBaseSrc for exactly one source pad, which
-should be named "src". A source implementation (subclass of #GstBaseSrc)
-should install a pad template in its class_init function, like so:
-|[&lt;!-- language="C" --&gt;
-static void
-my_element_class_init (GstMyElementClass *klass)
-{
-  GstElementClass *gstelement_class = GST_ELEMENT_CLASS (klass);
-  // srctemplate should be a #GstStaticPadTemplate with direction
-  // %GST_PAD_SRC and name "src"
-  gst_element_class_add_static_pad_template (gstelement_class, &amp;amp;srctemplate);
-
-  gst_element_class_set_static_metadata (gstelement_class,
-     "Source name",
-     "Source",
-     "My Source element",
-     "The author &lt;my.sink@my.email&gt;");
-}
-]|
-
-## Controlled shutdown of live sources in applications
-
-Applications that record from a live source may want to stop recording
-in a controlled way, so that the recording is stopped, but the data
-already in the pipeline is processed to the end (remember that many live
-sources would go on recording forever otherwise). For that to happen the
-application needs to make the source stop recording and send an EOS
-event down the pipeline. The application would then wait for an
-EOS message posted on the pipeline's bus to know when all data has
-been processed and the pipeline can safely be stopped.
-
-An application may send an EOS event to a source element to make it
-perform the EOS logic (send EOS event downstream or post a
-%GST_MESSAGE_SEGMENT_DONE on the bus). This can typically be done
-with the gst_element_send_event() function on the element or its parent bin.
-
-After the EOS has been sent to the element, the application should wait for
-an EOS message to be posted on the pipeline's bus. Once this EOS message is
-received, it may safely shut down the entire pipeline.</doc>

-           line="24">This base class is for filter elements that process data. Elements
-that are suitable for implementation using #GstBaseTransform are ones
-where the size and caps of the output is known entirely from the input
-caps and buffer sizes. These include elements that directly transform
-one buffer into another, modify the contents of a buffer in-place, as
-well as elements that collate multiple input buffers into one output buffer,
-or that expand one input buffer into multiple output buffers. See below
-for more concrete use cases.
-
-It provides for:
-
-* one sinkpad and one srcpad
-* Possible formats on sink and source pad implemented
-  with custom transform_caps function. By default uses
-  same format on sink and source.
-
-* Handles state changes
-* Does flushing
-* Push mode
-* Pull mode if the sub-class transform can operate on arbitrary data
-
-# Use Cases
-
-## Passthrough mode
-
-  * Element has no interest in modifying the buffer. It may want to inspect it,
-    in which case the element should have a transform_ip function. If there
-    is no transform_ip function in passthrough mode, the buffer is pushed
-    intact.
-
-  * The #GstBaseTransformClass.passthrough_on_same_caps variable
-    will automatically set/unset passthrough based on whether the
-    element negotiates the same caps on both pads.
-
-  * #GstBaseTransformClass.passthrough_on_same_caps on an element that
-    doesn't implement a transform_caps function is useful for elements that
-    only inspect data (such as level)
-
-  * Example elements
-
-    * Level
-    * Videoscale, audioconvert, videoconvert, audioresample in certain modes.
-
-## Modifications in-place - input buffer and output buffer are the same thing.
-
-* The element must implement a transform_ip function.
-* Output buffer size must &lt;= input buffer size
-* If the always_in_place flag is set, non-writable buffers will be copied
-  and passed to the transform_ip function, otherwise a new buffer will be
-  created and the transform function called.
-
-* Incoming writable buffers will be passed to the transform_ip function
-  immediately.
-* only implementing transform_ip and not transform implies always_in_place = %TRUE
-
-  * Example elements:
-    * Volume
-    * Audioconvert in certain modes (signed/unsigned conversion)
-    * videoconvert in certain modes (endianness swapping)
-
-## Modifications only to the caps/metadata of a buffer
-
-* The element does not require writable data, but non-writable buffers
-  should be subbuffered so that the meta-information can be replaced.
-
-* Elements wishing to operate in this mode should replace the
-  prepare_output_buffer method to create subbuffers of the input buffer
-  and set always_in_place to %TRUE
-
-* Example elements
-  * Capsfilter when setting caps on outgoing buffers that have
-    none.
-  * identity when it is going to re-timestamp buffers by
-    datarate.
-
-## Normal mode
-  * always_in_place flag is not set, or there is no transform_ip function
-  * Element will receive an input buffer and output buffer to operate on.
-  * Output buffer is allocated by calling the prepare_output_buffer function.
-  * Example elements:
-    * Videoscale, videoconvert, audioconvert when doing
-    scaling/conversions
-
-## Special output buffer allocations
-  * Elements which need to do special allocation of their output buffers
-    beyond allocating output buffers via the negotiated allocator or
-    buffer pool should implement the prepare_output_buffer method.
-
-  * Example elements:
-    * efence
-
-# Sub-class settable flags on GstBaseTransform
-
-* passthrough
-
-  * Implies that in the current configuration, the sub-class is not interested in modifying the buffers.
-  * Elements which are always in passthrough mode whenever the same caps has been negotiated on both pads can set the class variable passthrough_on_same_caps to have this behaviour automatically.
-
-* always_in_place
-  * Determines whether a non-writable buffer will be copied before passing
-    to the transform_ip function.
-
-  * Implied %TRUE if no transform function is implemented.
-  * Implied %FALSE if ONLY transform function is implemented.</doc>

-is given to the manager of this object when all pads have data.
-
-  * Collectpads are created with gst_collect_pads_new(). A callback should then
-    be installed with gst_collect_pads_set_function ().
-
-  * Pads are added to the collection with gst_collect_pads_add_pad()/
-    gst_collect_pads_remove_pad(). The pad has to be a sinkpad. When added,
-    the chain, event and query functions of the pad are overridden. The
-    element_private of the pad is used to store private information for the
-    collectpads.
-
-  * For each pad, data is queued in the _chain function or by
-    performing a pull_range.
-
-  * When data is queued on all pads in waiting mode, the callback function is called.
-
-  * Data can be dequeued from the pad with the gst_collect_pads_pop() method.
-    One can peek at the data with the gst_collect_pads_peek() function.
-    These functions will return %NULL if the pad received an EOS event. When all
-    pads return %NULL from a gst_collect_pads_peek(), the element can emit an EOS
-    event itself.
-
-  * Data can also be dequeued in byte units using the gst_collect_pads_available(),
-    gst_collect_pads_read_buffer() and gst_collect_pads_flush() calls.
-
-  * Elements should call gst_collect_pads_start() and gst_collect_pads_stop() in
-    their state change functions to start and stop the processing of the collectpads.
-    The gst_collect_pads_stop() call should be called before calling the parent
-    element state change function in the PAUSED_TO_READY state change to ensure
-    no pad is blocked and the element can finish streaming.
-
-  * gst_collect_pads_set_waiting() sets a pad to waiting or non-waiting mode.
-    CollectPads element is not waiting for data to be collected on non-waiting pads.
-    Thus these pads may but need not have data when the callback is called.
-    All pads are in waiting mode by default.</doc>

-the different #GstFlowReturn for those pads.
-
-#GstFlowCombiner works by using the last #GstFlowReturn for all #GstPad
-it has in its list and computes the combined return value and provides
-it to the caller.
-
-To add a new pad to the #GstFlowCombiner use gst_flow_combiner_add_pad().
-The new #GstPad is stored with a default value of %GST_FLOW_OK.
-
-In case you want a #GstPad to be removed, use gst_flow_combiner_remove_pad().
-
-Please be aware that this struct isn't thread safe as its designed to be
- used by demuxers, those usually will have a single thread operating it.
-
-These functions will take refs on the passed #GstPad&lt;!-- --&gt;s.
-
-Aside from reducing the user's code size, the main advantage of using this
-helper struct is to follow the standard rules for #GstFlowReturn combination.
-These rules are:
-
-* %GST_FLOW_EOS: only if all returns are EOS too
-* %GST_FLOW_NOT_LINKED: only if all returns are NOT_LINKED too
-* %GST_FLOW_ERROR or below: if at least one returns an error return
-* %GST_FLOW_NOT_NEGOTIATED: if at least one returns a not-negotiated return
-* %GST_FLOW_FLUSHING: if at least one returns flushing
-* %GST_FLOW_OK: otherwise
-
-%GST_FLOW_ERROR or below, GST_FLOW_NOT_NEGOTIATED and GST_FLOW_FLUSHING are
-returned immediately from the gst_flow_combiner_update_flow() function.</doc>

-
-Subclasses usually operate in a format that is different from the

-
-Classes extending this base class will usually be scheduled
-in a push based mode. If the peer accepts to operate without
-offsets and within the limits of the allowed block size, this
-class can operate in getrange based mode automatically. To make
-this possible, the subclass should implement and override the
-SCHEDULING query.
-
-The subclass should extend the methods from the baseclass in
-addition to the ::create method.
-
-Seeking, flushing, scheduling and sync is all handled by this

-Note that in contrast with other uses of #GDestroyNotify
-functions, @clear_func is expected to clear the contents of

-implements a #GstClock that synchronizes its time to a remote NTPv4 server.
-
-A new clock is created with gst_net_client_clock_new() or
-gst_ntp_clock_new(), which takes the address and port of the remote time
-provider along with a name and an initial time.
-
-This clock will poll the time provider and will update its calibration
-parameters based on the local and remote observations.
-
-The "round-trip" property limits the maximum round trip packets can take.
-
-Various parameters of the clock can be configured with the parent #GstClock
-"timeout", "window-size" and "window-threshold" object properties.
-
-A #GstNetClientClock and #GstNtpClock is typically set on a #GstPipeline with
-gst_pipeline_use_clock().
-
-If you set a #GstBus on the clock via the "bus" object property, it will
-send @GST_MESSAGE_ELEMENT messages with an attached #GstStructure containing
-statistics about clock accuracy and network traffic.</doc>

-mode, that allows a GStreamer pipeline to synchronize to a PTP network
-clock in some specific domain.
-
-The PTP subsystem can be initialized with gst_ptp_init(), which then starts
-a helper process to do the actual communication via the PTP ports. This is
-required as PTP listens on ports &lt; 1024 and thus requires special
-privileges. Once this helper process is started, the main process will
-synchronize to all PTP domains that are detected on the selected
-interfaces.
-
-gst_ptp_clock_new() then allows to create a GstClock that provides the PTP
-time from a master clock inside a specific PTP domain. This clock will only
-return valid timestamps once the timestamps in the PTP domain are known. To
-check this, you can use gst_clock_wait_for_sync(), the GstClock::synced
-signal and gst_clock_is_synced().
-
-To gather statistics about the PTP clock synchronization,
-gst_ptp_statistics_callback_add() can be used. This gives the application
-the possibility to collect all kinds of statistics from the clock
-synchronization.</doc>

-If gst_ptp_init() was not called before, this will call gst_ptp_init() with
-default parameters.
-
-This clock only returns valid timestamps after it received the first
-times from the PTP master clock on the network. Once this happens the

-
-It provides two APIs, allowing usage in blocking or non-blocking mode.
-
-The blocking mode just requires calling gst_discoverer_discover_uri()
-with the URI one wishes to discover.
-
-The non-blocking mode requires a running #GMainLoop iterating a
-#GMainContext, where one connects to the various signals, appends the
-URIs to be processed (through gst_discoverer_discover_uri_async()) and then
-asks for the discovery to begin (through gst_discoverer_start()).
-By default this will use the GLib default main context unless you have
-set a custom context using g_main_context_push_thread_default().
-
-All the information is returned in a #GstDiscovererInfo structure.</doc>

-The #GstDiscovererStreamInfo represents the topology of the stream. Siblings

-
-Encoding profiles describe the media types and settings one wishes to use
-for an encoding process. The top-level profiles are commonly
-#GstEncodingContainerProfile(s) (which contains a user-readable name and
-description along with which container format to use). These, in turn,
-reference one or more #GstEncodingProfile(s) which indicate which encoding
-format should be used on each individual streams.
-
-#GstEncodingProfile(s) can be provided to the 'encodebin' element, which
-will take care of selecting and setting up the required elements to produce
-an output stream conforming to the specifications of the profile.
-
-Unlike other systems, the encoding profiles do not specify which #GstElement
-to use for the various encoding and muxing steps, but instead relies on
-specifying the format one wishes to use.
-
-Encoding profiles can be created at runtime by the application or loaded
-from (and saved to) file using the #GstEncodingTarget API.
-
-## Defining a GstEncodingProfile as a string
-
-### Serialized encoding profile formats
-
-#### Using encoders and muxer element factory name:
-
-```
-  muxer_factory_name:video_encoder_factory_name:audio_encoder_factory_name
-```
-
-For example to encode a stream into a WebM container, with an OGG audio
-stream and a VP8 video stream, the serialized #GstEncodingProfile looks
-like:
-
-```
-  webmmux:vp8enc:vorbisenc
-```
-
-#### Define the encoding profile in a generic way using caps:
-
-```
-  muxer_source_caps:video_encoder_source_caps:audio_encoder_source_caps
-```
-
-For example to encode a stream into a WebM container, with an OGG audio
-stream and a VP8 video stream, the serialized #GstEncodingProfile looks
-like:
-
-```
-  video/webm:video/x-vp8:audio/x-vorbis
-```
-
-It is possible to mix caps and element type names so you can specify a specific
-video encoder while using caps for other encoders/muxer.
-
-### Advanced encoding format serialization features:
-
-You can also set the preset name of the encoding profile using the
-caps+preset_name syntax as in:
-
-```
-  video/webm:video/x-vp8+youtube-preset:audio/x-vorbis
-```
-
-Moreover, you can set extra properties `presence`, `single-segment` and
-`variable-framerate` * of an * encoding profile using the `|presence=` syntax
-as in:
-
-```
-  video/webm:video/x-vp8|presence=1,variable-framerate=true|single-segment=true:audio/x-vorbis
-```
-
-This field allows specifies the maximum number of times a
-#GstEncodingProfile can be used inside an encodebin. If 0, it is not a
-mandatory stream and can be used as many times as necessary.
-
-You can also use the `restriction_caps-&gt;encoded_format_caps` syntax to
-specify the restriction caps to be set on a #GstEncodingProfile
-
-It corresponds to the restriction #GstCaps to apply before the encoder that
-will be used in the profile. The fields present in restriction caps are
-properties of the raw stream (that is, before encoding), such as height and
-width for video and depth and sampling rate for audio. This property does
-not make sense for muxers. See #gst_encoding_profile_get_restriction for
-more details.
-
-To force a video stream to be encoded with a Full HD resolution (using WebM
-as the container format, VP8 as the video codec and Vorbis as the audio
-codec), you should use:
-
-```
-  "video/webm:video/x-raw,width=1920,height=1080-&gt;video/x-vp8:audio/x-vorbis"
-```
-
-&gt; NOTE: Make sure to enclose into quotes to avoid '&gt;' to be reinterpreted by
-&gt; the shell.
-
-In the case you are using encoder types, the following is also possible:
-
-```
-  "matroskamux:x264enc,width=1920,height=1080:audio/x-vorbis"
-```
-
-## Some serialized encoding formats examples:
-
-MP3 audio and H264 in MP4:
-
-```
-  video/quicktime,variant=iso:video/x-h264:audio/mpeg,mpegversion=1,layer=3
-```
-
-Vorbis and theora in OGG:
-
-```
-  application/ogg:video/x-theora:audio/x-vorbis
-```
-
-AC3 and H264 in MPEG-TS:
-
-```
-  video/mpegts:video/x-h264:audio/x-ac3
-```
-
-## Loading a profile from encoding targets
-
-Anywhere where you have to use a string to define a #GstEncodingProfile,
-you can use load it from a #GstEncodingTarget using the following syntaxes:
-
-```
-  target_name[/profilename/category]
-```
-
-or
-
-```
-  /path/to/target.gep:profilename
-```

-Encoding Targets are basically a higher level of abstraction to define formats
-for specific target types. Those can define several GstEncodingProfiles with
-different names, for example one for transcoding in full HD, another one for
-low res, etc.. which are defined in the same encoding target.

-Basically if you want to encode a stream to send it to, say, youtube you should

-
-Using this API, applications can request the installation of missing
-GStreamer plugins. These may be missing decoders/demuxers or
-encoders/muxers for a certain format, sources or sinks for a certain URI
-protocol (e.g. 'http'), or certain elements known by their element
-factory name ('audioresample').
-
-Whether plugin installation is supported or not depends on the operating
-system and/or distribution in question. The vendor of the operating
-system needs to make sure the necessary hooks and mechanisms are in
-place for plugin installation to work. See below for more detailed
-information.
-
-From the application perspective, plugin installation is usually
-triggered either
-
--   when the application itself has found that it wants or needs to
-    install a certain element
--   when the application has been notified by an element (such as
-    playbin or decodebin) that one or more plugins are missing *and* the
-    application has decided that it wants to install one or more of
-    those missing plugins
-
-The install functions in this section all take one or more 'detail
-strings'. These detail strings contain information about the type of
-plugin that needs to be installed (decoder, encoder, source, sink, or
-named element), and some additional information such GStreamer version
-used and a human-readable description of the component to install for
-user dialogs.
-
-Applications should not concern themselves with the composition of the
-string itself. They should regard the string as if it was a shared
-secret between GStreamer and the plugin installer application.
-
-Detail strings can be obtained using the function
-gst_missing_plugin_message_get_installer_detail() on a
-missing-plugin message. Such a message will either have been found by
-the application on a pipeline's #GstBus, or the application will have
-created it itself using gst_missing_element_message_new(),
-gst_missing_decoder_message_new(),
-gst_missing_encoder_message_new(),
-gst_missing_uri_sink_message_new(), or
-gst_missing_uri_source_message_new().
-
-For each GStreamer element/plugin/component that should be installed,
-the application needs one of those 'installer detail' string mentioned
-in the previous section. This string can be obtained, as already
-mentioned above, from a missing-plugin message using the function
-gst_missing_plugin_message_get_installer_detail(). The
-missing-plugin message is either posted by another element and then
-found on the bus by the application, or the application has created it
-itself as described above.
-
-The application will then call gst_install_plugins_async(), passing a
-NULL-terminated array of installer detail strings, and a function that
-should be called when the installation of the plugins has finished
-(successfully or not). Optionally, a #GstInstallPluginsContext created
-with gst_install_plugins_context_new() may be passed as well. This
-way additional optional arguments like the application window's XID can
-be passed to the external installer application.
-
-gst_install_plugins_async() will return almost immediately, with the
-return code indicating whether plugin installation was started or not.
-If the necessary hooks for plugin installation are in place and an
-external installer application has in fact been called, the passed in
-function will be called with a result code as soon as the external
-installer has finished. If the result code indicates that new plugins
-have been installed, the application will want to call
-gst_update_registry() so the run-time plugin registry is updated and
-the new plugins are made available to the application.
-
-&gt; A Gtk/GLib main loop must be running in order for the result function
-&gt; to be called when the external installer has finished. If this is not
-&gt; the case, make sure to regularly call in your code:
-&gt;
-&gt; g_main_context_iteration (NULL,FALSE);
-
-## 1. Installer hook
-
-When GStreamer applications initiate plugin installation via
-gst_install_plugins_async() or gst_install_plugins_sync(), a
-pre-defined helper application will be called.
-
-The exact path of the helper application to be called is set at compile
-time, usually by the build system based on the install prefix.
-For a normal package build into the `/usr` prefix, this will usually
-default to `/usr/libexec/gst-install-plugins-helper` or
-`/usr/lib/gst-install-plugins-helper`.
-
-Vendors/distros who want to support GStreamer plugin installation should
-either provide such a helper script/application or use the meson option
-`-Dinstall_plugins_helper'=/path/to/installer` to make GStreamer call an
-installer of their own directly.
-
-It is strongly recommended that vendors provide a small helper
-application as interlocutor to the real installer though, even more so
-if command line argument munging is required to transform the command
-line arguments passed by GStreamer to the helper application into
-arguments that are understood by the real installer.
-
-The helper application path defined at compile time can be overridden at
-runtime by setting the GST_INSTALL_PLUGINS_HELPER environment
-variable. This can be useful for testing/debugging purposes.
-
-## 2. Arguments passed to the install helper
-
-GStreamer will pass the following arguments to the install helper (this
-is in addition to the path of the executable itself, which is by
-convention argv[0]):
-
--   none to many optional arguments in the form of `--foo-bar=val`.
-    Example: `--transient-for=XID` where XID is the X Window ID of the
-    main window of the calling application (so the installer can make
-    itself transient to that window). Unknown optional arguments should
-    be ignored by the installer.
-
--   one 'installer detail string' argument for each plugin to be
-    installed; these strings will have a `gstreamer` prefix; the exact
-    format of the detail string is explained below
-
-## 3. Detail string describing the missing plugin
-
-The string is in UTF-8 encoding and is made up of several fields,
-separated by '|' characters (but neither the first nor the last
-character is a '|'). The fields are:
-
--   plugin system identifier, ie. "gstreamer"
-    This identifier determines the format of the rest of the detail
-    string. Automatic plugin installers should not process detail
-    strings with unknown identifiers. This allows other plugin-based
-    libraries to use the same mechanism for their automatic plugin
-    installation needs, or for the format to be changed should it turn
-    out to be insufficient.
--   plugin system version, e.g. "1.0"
-    This is required so that when there is GStreamer-2.0 at some point
-    in future, the different major versions can still co-exist and use
-    the same plugin install mechanism in the same way.
--   application identifier, e.g. "totem"
-    This may also be in the form of "pid/12345" if the program name
-    can't be obtained for some reason.
--   human-readable localised description of the required component, e.g.
-    "Vorbis audio decoder"
--   identifier string for the required component (see below for details
-    about how to map this to the package/plugin that needs installing),
-    e.g.
-    -   urisource-$(PROTOCOL_REQUIRED), e.g. urisource-http or
-        urisource-mms
-    -   element-$(ELEMENT_REQUIRED), e.g. element-videoconvert
-    -   decoder-$(CAPS_REQUIRED), e.g. (do read below for more
-        details!):
-        -   decoder-audio/x-vorbis
-        -   decoder-application/ogg
-        -   decoder-audio/mpeg, mpegversion=(int)4
-        -   decoder-video/mpeg, systemstream=(boolean)true,
-            mpegversion=(int)2
-    -   encoder-$(CAPS_REQUIRED), e.g. encoder-audio/x-vorbis
--   optional further fields not yet specified
-
-An entire ID string might then look like this, for example: `
-gstreamer|1.0|totem|Vorbis audio decoder|decoder-audio/x-vorbis`
-
-Plugin installers parsing this ID string should expect further fields
-also separated by '|' symbols and either ignore them, warn the user, or
-error out when encountering them.
-
-Those unfamiliar with the GStreamer 'caps' system should note a few
-things about the caps string used in the above decoder/encoder case:
-
--   the first part ("video/mpeg") of the caps string is a GStreamer
-    media type and *not* a MIME type. Wherever possible, the GStreamer
-    media type will be the same as the corresponding MIME type, but
-    often it is not.
--   a caps string may or may not have additional comma-separated fields
-    of various types (as seen in the examples above)
--   the caps string of a 'required' component (as above) will always
-    have fields with fixed values, whereas an introspected string (see
-    below) may have fields with non-fixed values. Compare for example:
-    -   `audio/mpeg, mpegversion=(int)4` vs.
-        `audio/mpeg, mpegversion=(int){2, 4}`
-    -   `video/mpeg, mpegversion=(int)2` vs.
-        `video/mpeg, systemstream=(boolean){ true, false}, mpegversion=(int)[1, 2]`

-## 4. Exit codes the installer should return
-
-The installer should return one of the following exit codes when it
-exits:
-
--   0 if all of the requested plugins could be installed
-    (#GST_INSTALL_PLUGINS_SUCCESS)
--   1 if no appropriate installation candidate for any of the requested
-    plugins could be found. Only return this if nothing has been
-    installed (#GST_INSTALL_PLUGINS_NOT_FOUND)
--   2 if an error occurred during the installation. The application will
-    assume that the user will already have seen an error message by the
-    installer in this case and will usually not show another one
-    (#GST_INSTALL_PLUGINS_ERROR)
--   3 if some of the requested plugins could be installed, but not all
-    (#GST_INSTALL_PLUGINS_PARTIAL_SUCCESS)
--   4 if the user aborted the installation
-    (#GST_INSTALL_PLUGINS_USER_ABORT)
-
-## 5. How to map the required detail string to packages
-
-It is up to the vendor to find mechanism to map required components from
-the detail string to the actual packages/plugins to install. This could
-be a hardcoded list of mappings, for example, or be part of the
-packaging system metadata.
-
-GStreamer plugin files can be introspected for this information. The
-`gst-inspect` utility has a special command line option that will output
-information similar to what is required. For example `
-$ gst-inspect-1.0 --print-plugin-auto-install-info /path/to/libgstvorbis.so
-should output something along the lines of
-`decoder-audio/x-vorbis`, `element-vorbisdec` `element-vorbisenc`
-`element-vorbisparse`, `element-vorbistag`, `encoder-audio/x-vorbis`
-
-Note that in the encoder and decoder case the introspected caps can be
-more complex with additional fields, e.g.
-`audio/mpeg,mpegversion=(int){2,4}`, so they will not always exactly
-match the caps wanted by the application. It is up to the installer to
-deal with this (either by doing proper caps intersection using the
-GStreamer #GstCaps API, or by only taking into account the media type).
-
-Another potential source of problems are plugins such as ladspa or
-libvisual where the list of elements depends on the installed
-ladspa/libvisual plugins at the time. This is also up to the
-distribution to handle (but usually not relevant for playback
-applications).</doc>

-
-Missing-plugin messages are posted on the bus by elements like decodebin
-or playbin if they can't find an appropriate source element or decoder
-element. The application can use these messages for two things:
-
-  * concise error/problem reporting to the user mentioning what exactly
-    is missing, see gst_missing_plugin_message_get_description()
-
-  * initiate installation of missing plugins, see
-    gst_missing_plugin_message_get_installer_detail() and
-    gst_install_plugins_async()
-
-Applications may also create missing-plugin messages themselves to install
-required elements that are missing, using the install mechanism mentioned
-above.</doc>

-audio codecs (constant bitrate)
-
-This class derives from GstRTPBasePayload. It can be used for payloading
-audio codecs. It will only work with constant bitrate codecs. It supports
-both frame based and sample based codecs. It takes care of packing up the
-audio data into RTP packets and filling up the headers accordingly. The
-payloading is done based on the maximum MTU (mtu) and the maximum time per
-packet (max-ptime). The general idea is to divide large data buffers into
-smaller RTP packets. The RTP packet size is the minimum of either the MTU,
-max-ptime (if set) or available data. The RTP packet size is always larger or
-equal to min-ptime (if set). If min-ptime is not set, any residual data is
-sent in a last RTP packet. In the case of frame based codecs, the resulting
-RTP packets always contain full frames.
-
-## Usage
-
-To use this base class, your child element needs to call either
-gst_rtp_base_audio_payload_set_frame_based() or
-gst_rtp_base_audio_payload_set_sample_based(). This is usually done in the
-element's `_init()` function. Then, the child element must call either
-gst_rtp_base_audio_payload_set_frame_options(),
-gst_rtp_base_audio_payload_set_sample_options() or
-gst_rtp_base_audio_payload_set_samplebits_options. Since
-GstRTPBaseAudioPayload derives from GstRTPBasePayload, the child element
-must set any variables or call/override any functions required by that base
-class. The child element does not need to override any other functions
-specific to GstRTPBaseAudioPayload.</doc>

-stream and handles things like typefinding, querying, seeking, and
-different modes of operation (chain-based, pull_range-based, and providing
-downstream elements with random access if upstream supports that). The tag
-is stripped from the output, and all offsets are adjusted for the tag
-sizes, so that to the downstream element the stream will appear as if
-there was no tag at all. Also, once the tag has been parsed, GstTagDemux
-will try to determine the media type of the resulting stream and add a
-source pad with the appropriate caps in order to facilitate auto-plugging.
-
-## Deriving from GstTagDemux
-
-Subclasses have to do four things:
-
- * In their base init function, they must add a pad template for the sink
-   pad to the element class, describing the media type they can parse in
-   the caps of the pad template.
- * In their class init function, they must override
-   GST_TAG_DEMUX_CLASS(demux_klass)-&gt;identify_tag with their own identify
-   function.
- * In their class init function, they must override
- GST_TAG_DEMUX_CLASS(demux_klass)-&gt;parse_tag with their own parse
- function.
- * In their class init function, they must also set
-   GST_TAG_DEMUX_CLASS(demux_klass)-&gt;min_start_size and/or
- GST_TAG_DEMUX_CLASS(demux_klass)-&gt;min_end_size to the minimum size required
- for the identify function to decide whether the stream has a supported tag
- or not. A class parsing ID3v1 tags, for example, would set min_end_size to
- 128 bytes.</doc>

-type.
-
-Background: cover art and other images in tags are usually stored as a
-blob of binary image data, often accompanied by a MIME type or some other
-content type string (e.g. 'png', 'jpeg', 'jpg'). Sometimes there is also an
-'image type' to indicate what kind of image this is (e.g. front cover,
-back cover, artist, etc.). The image data may also be an URI to the image
-rather than the image itself.
-
-In GStreamer, image tags are #GstSample&lt;!-- --&gt;s containing the raw image
-data, with the sample caps describing the content type of the image
-(e.g. image/jpeg, image/png, text/uri-list). The sample info may contain
-an additional 'image-type' field of #GstTagImageType to describe
-the type of image (front cover, back cover etc.). #GST_TAG_PREVIEW_IMAGE
-tags should not carry an image type, their type is already indicated via
-the special tag name.
-
-This function will do various checks and typefind the encoded image
-data (we can't trust the declared mime type).</doc>

-events such as mouse button presses, cursor motion and key presses. The associated
-library also provides methods for parsing received events, and for sending and
-receiving navigation related bus events. One main usecase is DVD menu navigation.
-
-The main parts of the API are:
-
-* The GstNavigation interface, implemented by elements which provide an application
-  with the ability to create and inject navigation events into the pipeline.
-* GstNavigation event handling API. GstNavigation events are created in response to
-  calls on a GstNavigation interface implementation, and sent in the pipeline. Upstream
-  elements can use the navigation event API functions to parse the contents of received
-  messages.
-
-* GstNavigation message handling API. GstNavigation messages may be sent on the message
-  bus to inform applications of navigation related changes in the pipeline, such as the
-  mouse moving over a clickable region, or the set of available angles changing.
-
-The GstNavigation message functions provide functions for creating and parsing
-custom bus messages for signaling GstNavigation changes.</doc>

-
-Notes:
-
-1) AFD 0 is undefined for ATSC and SMPTE ST2016-1, indicating that AFD data is not available:
-If Bar Data is not present, AFD '0000' indicates that exact information
-is not available and the active image should be assumed to be the same as the coded frame. AFD '0000'.
-AFD '0000' accompanied by Bar Data signals that the active image’s aspect ratio is narrower than 16:9,
-but is not 4:3 or 14:9. As the exact aspect ratio cannot be conveyed by AFD alone, wherever possible,
-AFD ‘0000’ should be accompanied by Bar Data to define the exact vertical or horizontal extent
-of the active image.
-2) AFD 0 is reserved for DVB/ETSI
-3) values 1, 5, 6, 7, and 12 are reserved for both ATSC and DVB/ETSI
-4) values 2 and 3 are not recommended for ATSC, but are valid for DVB/ETSI</doc>

-           line="25">This base class is for video decoders turning encoded data into raw video
-frames.
-
-The GstVideoDecoder base class and derived subclasses should cooperate as
-follows:
-
-## Configuration
-
-  * Initially, GstVideoDecoder calls @start when the decoder element
-    is activated, which allows the subclass to perform any global setup.
-
-  * GstVideoDecoder calls @set_format to inform the subclass of caps
-    describing input video data that it is about to receive, including
-    possibly configuration data.
-    While unlikely, it might be called more than once, if changing input
-    parameters require reconfiguration.
-
-  * Incoming data buffers are processed as needed, described in Data
-    Processing below.
-
-  * GstVideoDecoder calls @stop at end of all processing.
-
-## Data processing
-
-  * The base class gathers input data, and optionally allows subclass
-    to parse this into subsequently manageable chunks, typically
-    corresponding to and referred to as 'frames'.
-
-  * Each input frame is provided in turn to the subclass' @handle_frame
-    callback.
-    The ownership of the frame is given to the @handle_frame callback.
-
-  * If codec processing results in decoded data, the subclass should call
-    @gst_video_decoder_finish_frame to have decoded data pushed.
-    downstream. Otherwise, the subclass must call
-    @gst_video_decoder_drop_frame, to allow the base class to do timestamp
-    and offset tracking, and possibly to requeue the frame for a later
-    attempt in the case of reverse playback.
-
-## Shutdown phase
-
-  * The GstVideoDecoder class calls @stop to inform the subclass that data
-    parsing will be stopped.
-
-## Additional Notes
-
-  * Seeking/Flushing
-
-    * When the pipeline is seeked or otherwise flushed, the subclass is
-      informed via a call to its @reset callback, with the hard parameter
-      set to true. This indicates the subclass should drop any internal data
-      queues and timestamps and prepare for a fresh set of buffers to arrive
-      for parsing and decoding.
-
-  * End Of Stream
-
-    * At end-of-stream, the subclass @parse function may be called some final
-      times with the at_eos parameter set to true, indicating that the element
-      should not expect any more data to be arriving, and it should parse and
-      remaining frames and call gst_video_decoder_have_frame() if possible.
-
-The subclass is responsible for providing pad template caps for
-source and sink pads. The pads need to be named "sink" and "src". It also
-needs to provide information about the output caps, when they are known.
-This may be when the base class calls the subclass' @set_format function,
-though it might be during decoding, before calling
-@gst_video_decoder_finish_frame. This is done via
-@gst_video_decoder_set_output_state
-
-The subclass is also responsible for providing (presentation) timestamps
-(likely based on corresponding input ones).  If that is not applicable
-or possible, the base class provides limited framerate based interpolation.
-
-Similarly, the base class provides some limited (legacy) seeking support
-if specifically requested by the subclass, as full-fledged support
-should rather be left to upstream demuxer, parser or alike.  This simple
-approach caters for seeking and duration reporting using estimated input
-bitrates. To enable it, a subclass should call
-@gst_video_decoder_set_estimate_rate to enable handling of incoming
-byte-streams.
-
-The base class provides some support for reverse playback, in particular
-in case incoming data is not packetized or upstream does not provide
-fragments on keyframe boundaries.  However, the subclass should then be
-prepared for the parsing and frame processing stage to occur separately
-(in normal forward processing, the latter immediately follows the former),
-The subclass also needs to ensure the parsing stage properly marks
-keyframes, unless it knows the upstream elements will do so properly for
-incoming data.
-
-The bare minimum that a functional subclass needs to implement is:
-
-  * Provide pad templates
-  * Inform the base class of output caps via
-     @gst_video_decoder_set_output_state
-
-  * Parse input data, if it is not considered packetized from upstream
-     Data will be provided to @parse which should invoke
-     @gst_video_decoder_add_to_frame and @gst_video_decoder_have_frame to
-     separate the data belonging to each video frame.
-
-  * Accept data in @handle_frame and provide decoded results to
-     @gst_video_decoder_finish_frame, or call @gst_video_decoder_drop_frame.</doc>

-a new sync should be requested from upstream, and that @frame was the frame
-when the subclass noticed that a new sync point is required. A reason for
-the subclass to do this could be missing reference frames, for example.
-
-The base class will then request a new sync point from upstream as long as
-the time that passed since the last one is exceeding
-#GstVideoDecoder:min-force-key-unit-interval.
-
-The subclass can signal via @flags how the frames until the next sync point
-should be handled:
-
-  * If %GST_VIDEO_DECODER_REQUEST_SYNC_POINT_DISCARD_INPUT is selected then
-    all following input frames until the next sync point are discarded.
-    This can be useful if the lack of a sync point will prevent all further
-    decoding and the decoder implementation is not very robust in handling
-    missing references frames.
-  * If %GST_VIDEO_DECODER_REQUEST_SYNC_POINT_CORRUPT_OUTPUT is selected
-    then all output frames following @frame are marked as corrupted via
-    %GST_BUFFER_FLAG_CORRUPTED. Corrupted frames can be automatically
-    dropped by the base class, see #GstVideoDecoder:discard-corrupted-frames.
-    Subclasses can manually mark frames as corrupted via %GST_VIDEO_CODEC_FRAME_FLAG_CORRUPTED

-           line="25">This base class is for video encoders turning raw video into
-encoded video data.
-
-GstVideoEncoder and subclass should cooperate as follows.
-
-## Configuration
-
-  * Initially, GstVideoEncoder calls @start when the encoder element
-    is activated, which allows subclass to perform any global setup.
-  * GstVideoEncoder calls @set_format to inform subclass of the format
-    of input video data that it is about to receive.  Subclass should
-    setup for encoding and configure base class as appropriate
-    (e.g. latency). While unlikely, it might be called more than once,
-    if changing input parameters require reconfiguration.  Baseclass
-    will ensure that processing of current configuration is finished.
-  * GstVideoEncoder calls @stop at end of all processing.
-
-## Data processing
-
-    * Base class collects input data and metadata into a frame and hands
-      this to subclass' @handle_frame.
-
-    * If codec processing results in encoded data, subclass should call
-      @gst_video_encoder_finish_frame to have encoded data pushed
-      downstream.
-
-    * If implemented, baseclass calls subclass @pre_push just prior to
-      pushing to allow subclasses to modify some metadata on the buffer.
-      If it returns GST_FLOW_OK, the buffer is pushed downstream.
-
-    * GstVideoEncoderClass will handle both srcpad and sinkpad events.
-      Sink events will be passed to subclass if @event callback has been
-      provided.
-
-## Shutdown phase
-
-  * GstVideoEncoder class calls @stop to inform the subclass that data
-    parsing will be stopped.
-
-Subclass is responsible for providing pad template caps for
-source and sink pads. The pads need to be named "sink" and "src". It should
-also be able to provide fixed src pad caps in @getcaps by the time it calls
-@gst_video_encoder_finish_frame.
-
-Things that subclass need to take care of:
-
-  * Provide pad templates
-  * Provide source pad caps before pushing the first buffer
-  * Accept data in @handle_frame and provide encoded results to
-     @gst_video_encoder_finish_frame.
-
-
-The #GstVideoEncoder:qos property will enable the Quality-of-Service
-features of the encoder which gather statistics about the real-time
-performance of the downstream elements. If enabled, subclasses can
-use gst_video_encoder_get_max_encode_time() to check if input frames
-are already late and drop them right away to give a chance to the
-pipeline to catch up.</doc>

-should be a multiple of pack_lines.
-
-Subsampled formats will use the horizontally and vertically cosited

-
-This meta can also be used by downstream elements to specifiy their
-buffer layout requirements for upstream. Upstream should try to
-fit those requirements, if possible, in order to prevent buffer copies.
-
-This is done by passing a custom #GstStructure to
-gst_query_add_allocation_meta() when handling the ALLOCATION query.
-This structure should be named 'video-meta' and can have the following
-fields:
-- padding-top (uint): extra pixels on the top
-- padding-bottom (uint): extra pixels on the bottom
-- padding-left (uint): extra pixels on the left side
-- padding-right (uint): extra pixels on the right side
-The padding fields have the same semantic as #GstVideoMeta.alignment
-and so represent the paddings requested on produced video buffers.</doc>

-           line="20">The #GstVideoOverlay interface is used for 2 main purposes :
-
-* To get a grab on the Window where the video sink element is going to render.
-  This is achieved by either being informed about the Window identifier that
-  the video sink element generated, or by forcing the video sink element to use
-  a specific Window identifier for rendering.
-* To force a redrawing of the latest video frame the video sink element
-  displayed on the Window. Indeed if the #GstPipeline is in #GST_STATE_PAUSED
-  state, moving the Window around will damage its content. Application
-  developers will want to handle the Expose events themselves and force the
-  video sink element to refresh the Window's content.
-
-Using the Window created by the video sink is probably the simplest scenario,
-in some cases, though, it might not be flexible enough for application
-developers if they need to catch events such as mouse moves and button
-clicks.
-
-Setting a specific Window identifier on the video sink element is the most
-flexible solution but it has some issues. Indeed the application needs to set
-its Window identifier at the right time to avoid internal Window creation
-from the video sink element. To solve this issue a #GstMessage is posted on
-the bus to inform the application that it should set the Window identifier
-immediately. Here is an example on how to do that correctly:
-|[
-static GstBusSyncReply
-create_window (GstBus * bus, GstMessage * message, GstPipeline * pipeline)
-{
- // ignore anything but 'prepare-window-handle' element messages
- if (!gst_is_video_overlay_prepare_window_handle_message (message))
-   return GST_BUS_PASS;
-
- win = XCreateSimpleWindow (disp, root, 0, 0, 320, 240, 0, 0, 0);
-
- XSetWindowBackgroundPixmap (disp, win, None);
-
- XMapRaised (disp, win);
-
- XSync (disp, FALSE);
-
- gst_video_overlay_set_window_handle (GST_VIDEO_OVERLAY (GST_MESSAGE_SRC (message)),
-     win);
-
- gst_message_unref (message);
-
- return GST_BUS_DROP;
-}
-...
-int
-main (int argc, char **argv)
-{
-...
- bus = gst_pipeline_get_bus (GST_PIPELINE (pipeline));
- gst_bus_set_sync_handler (bus, (GstBusSyncHandler) create_window, pipeline,
-        NULL);
-...
-}
-]|
-
-## Two basic usage scenarios
-
-There are two basic usage scenarios: in the simplest case, the application
-uses #playbin or #playsink or knows exactly what particular element is used
-for video output, which is usually the case when the application creates
-the videosink to use (e.g. #xvimagesink, #ximagesink, etc.) itself; in this
-case, the application can just create the videosink element, create and
-realize the window to render the video on and then
-call gst_video_overlay_set_window_handle() directly with the XID or native
-window handle, before starting up the pipeline.
-As #playbin and #playsink implement the video overlay interface and proxy
-it transparently to the actual video sink even if it is created later, this
-case also applies when using these elements.
-
-In the other and more common case, the application does not know in advance
-what GStreamer video sink element will be used for video output. This is
-usually the case when an element such as #autovideosink is used.
-In this case, the video sink element itself is created
-asynchronously from a GStreamer streaming thread some time after the
-pipeline has been started up. When that happens, however, the video sink
-will need to know right then whether to render onto an already existing
-application window or whether to create its own window. This is when it
-posts a prepare-window-handle message, and that is also why this message needs
-to be handled in a sync bus handler which will be called from the streaming
-thread directly (because the video sink will need an answer right then).
-
-As response to the prepare-window-handle element message in the bus sync
-handler, the application may use gst_video_overlay_set_window_handle() to tell
-the video sink to render onto an existing window surface. At this point the
-application should already have obtained the window handle / XID, so it
-just needs to set it. It is generally not advisable to call any GUI toolkit
-functions or window system functions from the streaming thread in which the
-prepare-window-handle message is handled, because most GUI toolkits and
-windowing systems are not thread-safe at all and a lot of care would be
-required to co-ordinate the toolkit and window system calls of the
-different threads (Gtk+ users please note: prior to Gtk+ 2.18
-`GDK_WINDOW_XID` was just a simple structure access, so generally fine to do
-within the bus sync handler; this macro was changed to a function call in
-Gtk+ 2.18 and later, which is likely to cause problems when called from a
-sync handler; see below for a better approach without `GDK_WINDOW_XID`
-used in the callback).

-
-An overlay composition describes one or more overlay rectangles to be
-blended on top of a video buffer.
-
-This API serves two main purposes:
-
-* it can be used to attach overlay information (subtitles or logos)
-  to non-raw video buffers such as GL/VAAPI/VDPAU surfaces. The actual
-  blending of the overlay can then be done by e.g. the video sink that
-  processes these non-raw buffers.
-
-* it can also be used to blend overlay rectangles on top of raw video
-  buffers, thus consolidating blending functionality for raw video in
-  one place.
-
-Together, this allows existing overlay elements to easily handle raw
-and non-raw video as input in without major changes (once the overlays
-have been put into a #GstVideoOverlayComposition object anyway) - for raw
-video the overlay can just use the blending function to blend the data
-on top of the video, and for surface buffers it can just attach them to
-the buffer and let the sink render the overlays.</doc>
