+      <doc xml:space="preserve" filename="../subprojects/gst-editing-services/ges/ges-asset.c">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) {
+     gst_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>

+      <doc xml:space="preserve" filename="../subprojects/gst-editing-services/ges/ges-base-effect.c">A #GESBaseEffect is some operation that applies an effect to the data
+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)
+{

+This will take any time effects placed on the clip into account (see
+#GESBaseEffect for what time effects are supported, and how to
+declare them in GES).
+
+When @timeline_time is above the #GESTimelineElement:start of @clip,
+this will return the internal time at which the content that appears at
+@timeline_time in the output of the timeline is created in @child. For
+example, if @timeline_time corresponds to the current seek position,
+this would let you know which part of a media file is being read.
+
+This will be done assuming the clip has an indefinite end, so the
+internal time may be beyond the current out-point of the child, or even
+its #GESTimelineElement:max-duration.
+
+If, instead, @timeline_time is below the current
+#GESTimelineElement:start of @clip, this will return what you would
+need to set the #GESTimelineElement:in-point of @child to if you set
+the #GESTimelineElement:start of @clip to @timeline_time and wanted
+to keep the content of @child currently found at the current
+#GESTimelineElement:start of @clip at the same timeline position. If
+this would be negative, the conversion fails. This is useful for
+determining what #GESTimelineElement:in-point would result from a

+
+Note that whilst a clip has no time effects, this second return is
+equivalent to finding the internal time at which the content that
+appears at @timeline_time in the timeline can be found in @child if it
+had indefinite extent in both directions. However, with non-linear time
+effects this second return will be more distinct.

+This will take any time effects placed on the clip into account (see
+#GESBaseEffect for what time effects are supported, and how to
+declare them in GES).
+
+When @internal_time is above the #GESTimelineElement:in-point of
+@child, this will return the timeline time at which the internal
+content found at @internal_time appears in the output of the timeline's
+track. For example, this would let you know where in the timeline a
+particular scene in a media file would appear.
+
+This will be done assuming the clip has an indefinite end, so the
+timeline time may be beyond the end of the clip, or even breaking its
+#GESClip:duration-limit.
+
+If, instead, @internal_time is below the current
+#GESTimelineElement:in-point of @child, this will return what you would
+need to set the #GESTimelineElement:start of @clip to if you set the
+#GESTimelineElement:in-point of @child to @internal_time and wanted to
+keep the content of @child currently found at the current
+#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

+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>

+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>

+      <doc xml:space="preserve" filename="../subprojects/gst-editing-services/ges/ges-group.c">A #GESGroup controls one or more #GESContainer-s (usually #GESClip-s,
+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
+have its images shown first. The other layer will only have its image
+shown if the higher priority layer has no content at the given
+playtime, or is transparent in some way. Audio content in separate
+layers will simply play in addition.</doc>

+it, that is data that is unimportant to its function within GES, but
+may hold some useful information. In particular,
+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>

+The #GESProject class offers a higher level API to handle #GESAsset-s.

+
+## 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

+
+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.
+
+NOTE: if you know what you are doing and want to be in full control of the
+timeline layout, you can disable the edit APIs with
+#ges_timeline_disable_edit_apis.
+
+## 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>

+        <doc xml:space="preserve" filename="../subprojects/gst-editing-services/ges/ges-timeline.c">This will be emitted whenever the timeline needs to determine which
+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>

+      <doc xml:space="preserve" filename="../subprojects/gst-editing-services/ges/ges-timeline-element.c">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>

+properties of the element have any meaning. In particular, unless
+this is set to %TRUE, the #GESTimelineElement:in-point and
+#GESTimelineElement:max-duration can not be set to any value other
+than the default 0 and #GST_CLOCK_TIME_NONE, respectively.
+
+If an element has some *internal* *timed* source #GstElement that it
+reads stream data from as part of its function in a #GESTrack, then
+you'll likely want to set this to %TRUE to allow the
+#GESTimelineElement:in-point and #GESTimelineElement:max-duration to
+be set.
+
+The default value is determined by the #GESTrackElementClass
+@default_has_internal_source class property. For most
+#GESSourceClass-es, this will be %TRUE, with the exception of those
+that have a potentially *static* source, such as #GESImageSourceClass
+and #GESTitleSourceClass. Otherwise, this will usually be %FALSE.
+
+For most #GESOperation-s you will likely want to leave this set to
+%FALSE. The exception may be for an operation that reads some stream
+data from some private internal source as part of manipulating the
+input data from the usual linked upstream #GESTrackElement.
+
+For example, you may want to set this to %TRUE for a
+#GES_TRACK_TYPE_VIDEO operation that wraps a #textoverlay that reads
+from a subtitle file and places its text on top of the received video
+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
+time at which the subtitle file runs out of data.

+Note that GES can not support track elements that have both internal
+content and manipulate the timing of their data streams (time

+      <doc xml:space="preserve" filename="../subprojects/gstreamer/gst/gstbin.c">#GstBin is an element that can contain other #GstElement, allowing them to be
+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.
+
+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 to 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.
+

+      <doc xml:space="preserve" filename="../subprojects/gstreamer/gst/gstbuffer.c">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.
+
+``` C
+  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>

+
+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 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

+      <doc xml:space="preserve" filename="../subprojects/gstreamer/gst/gstbus.c">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 #GMainLoop.
+
+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 #GMainLoop 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>

+      <doc xml:space="preserve" filename="../subprojects/gstreamer/gst/gstcaps.c">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:
+
+``` C
+  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 fields 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 until 1.20 the #GstCaps / #GstStructure serialization into string
+had limited support for nested #GstCaps / #GstStructure fields. It could only
+support one level of nesting. Using more levels would lead to unexpected
+behavior when using serialization features, such as gst_caps_to_string() or
+gst_value_serialize() and their counterparts.</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>

+      <doc xml:space="preserve" filename="../subprojects/gstreamer/gst/gstclock.c">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
+#GST_EVENT_SEGMENT 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
+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 they are 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 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>

+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 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>

+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; When naming your category, please follow the following conventions to ensure

+&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>

+      <doc xml:space="preserve" filename="../subprojects/gstreamer/gst/gstelement.c">GstElement is the abstract base class needed to construct an element that
+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>

+      <doc xml:space="preserve" filename="../subprojects/gstreamer/gst/gstevent.c">The event class provides factory methods to construct events for sending
+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.

+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
+value to convert the buffer timestamps into the stream time. This is

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

+The idea here is to create hierarchical element graphs. The bin element

+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>

+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;

+      <doc xml:space="preserve" filename="../subprojects/gstreamer/gst/gstmemory.c">GstMemory is a lightweight refcounted object that wraps a region of memory.
+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>

+from a different location. This is useful if such a redirection cannot be
+handled inside a source element, for example when HTTP 302/303 redirects
+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.
+
+The specified location string is copied. However, ownership over the tag
+list and structure are transferred to the message.</doc>

+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>

+      <doc xml:space="preserve" filename="../subprojects/gstreamer/gst/gstobject.c">#GstObject provides a root for the object hierarchy tree filed in by the
+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);
+

+      <doc xml:space="preserve" filename="../subprojects/gstreamer/gst/gstpad.c">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

+Furthermore, some downstream events have to be serialized with data flow,

+#GST_EVENT_IS_UPSTREAM, #GST_EVENT_IS_DOWNSTREAM, and

+This function is installed on a source pad with

+
+Any @offset larger or equal than the length will make the function return

+      <doc xml:space="preserve" filename="../subprojects/gstreamer/gst/gstpadtemplate.c">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_request_pad_simple()
+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;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;my_template);
+  }

+      <doc xml:space="preserve" filename="../subprojects/gstreamer/gst/gstpipeline.c">A #GstPipeline is a special #GstBin used as the toplevel container for
+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
+should be retrieved with gst_pipeline_get_bus(). This #GstBus should then
+be used to receive #GstMessage from the elements in the pipeline. Listening
+to the #GstBus is necessary for retrieving error messages from the
+#GstPipeline and otherwise the #GstPipeline might stop without any
+indication, why. Furthermore, the #GstPipeline posts messages even if
+nobody listens on the #GstBus, which will pile up and use up memory.
+
+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

+readable and/or writable. It is possible to make this wait be controlled
+by specifying %TRUE for the @controllable flag when creating the set (or
+later calling gst_poll_set_controllable()).
+
+New file descriptors are added to the set using gst_poll_add_fd(), and
+removed using gst_poll_remove_fd(). Controlling which file descriptors
+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,
+gst_poll_fd_has_error() to see if it has generated an error,

+      <doc xml:space="preserve" filename="../subprojects/gstreamer/gst/gstpreset.c">This interface offers methods to query and manipulate parameter preset sets.
+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>

+      <doc xml:space="preserve" filename="../subprojects/gstreamer/gst/gstpromise.c">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>

+      <doc xml:space="preserve" filename="../subprojects/gstreamer/gst/gstsegment.h">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>

+      <doc xml:space="preserve" filename="../subprojects/gstreamer/gst/gstsegment.c">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>

+      <doc xml:space="preserve" filename="../subprojects/gstreamer/gst/gststructure.c">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 semicolon `;`
+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"
+```
+
+Since 1.20, nested structures and caps can be specified using brackets (`[`
+and `]`), for example:
+
+```
+a-struct, nested=[nested-struct, nested=true]
+```
+
+&gt; *note*: gst_structure_to_string() won't use that syntax for backward
+&gt; compatibility reason, gst_structure_serialize() has been added for
+&gt; that purpose.</doc>

+
+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);
+

+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>

+
+It has to be used for non-mappable dma-buf only, i.e. when the underlying
+memory is not mappable to user space. Or when the mapped memory contains
+non meaningful data. It can be the case for protected content or when the
+user wants explicitly avoid any software post processing.
+
+In these cases all elements between the exported and the importer has to work
+in passthrough mode. This is done by adding this caps feature.
+
+When the memory is mappable for read and write requests then it is assumes
+to be a fast path and so this caps feature should not be used. Though
+according to the dma-buf protocol, while it is mapped it prevents the
+exporter to migrate the buffer.
+
+This caps feature should not serve at all the purpose of selecting the
+@GST_ALLOCATOR_DMABUF allocator during caps negotiation.
+When the exporter is the upstream element from the importer point of view,
+the exporter should try to map the dma buffer at runtime (preferably during
+decide_allocation phase). When it succeeds for #GST_MAP_READWRITE this caps
+feature should not be used. This allows scalers, color converts and any image
+processing filters to work directly on the dma buffer.
+In this case the importer element should check all incoming memory using
+gst_is_dmabuf_memory().</doc>

+      <doc xml:space="preserve" filename="../subprojects/gst-plugins-base/gst-libs/gst/app/gstappsink.c">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>

+      <doc xml:space="preserve" filename="../subprojects/gst-plugins-base/gst-libs/gst/app/gstappsrc.c">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", "max-buffers" and "max-time" properties control 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>

+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>

+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

+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>

+      <doc xml:space="preserve" filename="../subprojects/gst-plugins-base/gst-libs/gst/audio/gstaudiodecoder.c">This base class is for audio decoders turning encoded data into
+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>

+      <doc xml:space="preserve" filename="../subprojects/gst-plugins-base/gst-libs/gst/audio/gstaudioencoder.c">This base class is for audio encoders turning raw audio samples into
+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>

+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

+      <doc xml:space="preserve" filename="../subprojects/gst-plugins-bad/gst-libs/gst/audio/gstnonstreamaudiodecoder.c">This base class is for decoders which do not operate on a streaming model.
+That is: they load the encoded media at once, as part of an initialization,
+and afterwards can decode samples (sometimes referred to as "rendering the
+samples").
+
+This sets it apart from GstAudioDecoder, which is a base class for
+streaming audio decoders.
+
+The base class is conceptually a mix between decoder and parser. This is
+unavoidable, since virtually no format that isn't streaming based has a
+clear distinction between parsing and decoding. As a result, this class
+also handles seeking.
+
+Non-streaming audio formats tend to have some characteristics unknown to
+more "regular" bitstreams. These include subsongs and looping.
+
+Subsongs are a set of songs-within-a-song. An analogy would be a multitrack
+recording, where each track is its own song. The first subsong is typically
+the "main" one. Subsongs were popular for video games to enable context-
+aware music; for example, subsong `#0` would be the "main" song, `#1` would be
+an alternate song playing when a fight started, `#2` would be heard during
+conversations etc. The base class is designed to always have at least one
+subsong. If the subclass doesn't provide any, the base class creates a
+"pseudo" subsong, which is actually the whole song.
+Downstream is informed about the subsong using a table of contents (TOC),
+but only if there are at least 2 subsongs.
+
+Looping refers to jumps within the song, typically backwards to the loop
+start (although bi-directional looping is possible). The loop is defined
+by a chronological start and end; once the playback position reaches the
+loop end, it jumps back to the loop start.
+Depending on the subclass, looping may not be possible at all, or it
+may only be possible to enable/disable it (that is, either no looping, or
+an infinite amount of loops), or it may allow for defining a finite number
+of times the loop is repeated.
+Looping can affect output in two ways. Either, the playback position is
+reset to the start of the loop, similar to what happens after a seek event.
+Or, it is not reset, so the pipeline sees playback steadily moving forwards,
+the playback position monotonically increasing. However, seeking must
+always happen within the confines of the defined subsong duration; for
+example, if a subsong is 2 minutes long, steady playback is at 5 minutes
+(because infinite looping is enabled), then seeking will still place the
+position within the 2 minute period.
+Loop count 0 means no looping. Loop count -1 means infinite looping.
+Nonzero positive values indicate how often a loop shall occur.
+
+If the initial subsong and loop count are set to values the subclass does
+not support, the subclass has a chance to correct these values.
+@get_property then reports the corrected versions.
+
+The base class operates as follows:
+* Unloaded mode
+  - Initial values are set. If a current subsong has already been
+    defined (for example over the command line with gst-launch), then
+    the subsong index is copied over to current_subsong .
+    Same goes for the num-loops and output-mode properties.
+    Media is NOT loaded yet.
+  - Once the sinkpad is activated, the process continues. The sinkpad is
+    activated in push mode, and the class accumulates the incoming media
+    data in an adapter inside the sinkpad's chain function until either an
+    EOS event is received from upstream, or the number of bytes reported
+    by upstream is reached. Then it loads the media, and starts the decoder
+    output task.
+  - If upstream cannot respond to the size query (in bytes) of @load_from_buffer
+    fails, an error is reported, and the pipeline stops.
+  - If there are no errors, @load_from_buffer is called to load the media. The
+    subclass must at least call gst_nonstream_audio_decoder_set_output_format()
+    there, and is free to make use of the initial subsong, output mode, and
+    position. If the actual output mode or position differs from the initial
+    value,it must set the initial value to the actual one (for example, if
+    the actual starting position is always 0, set *initial_position to 0).
+    If loading is unsuccessful, an error is reported, and the pipeline
+    stops. Otherwise, the base class calls @get_current_subsong to retrieve
+    the actual current subsong, @get_subsong_duration to report the current
+    subsong's duration in a duration event and message, and @get_subsong_tags
+    to send tags downstream in an event (these functions are optional; if
+    set to NULL, the associated operation is skipped). Afterwards, the base
+    class switches to loaded mode, and starts the decoder output task.
+
+* Loaded mode&lt;/title&gt;
+  - Inside the decoder output task, the base class repeatedly calls @decode,
+    which returns a buffer with decoded, ready-to-play samples. If the
+    subclass reached the end of playback, @decode returns FALSE, otherwise
+    TRUE.
+  - Upon reaching a loop end, subclass either ignores that, or loops back
+    to the beginning of the loop. In the latter case, if the output mode is set
+    to LOOPING, the subclass must call gst_nonstream_audio_decoder_handle_loop()
+    *after* the playback position moved to the start of the loop. In
+    STEADY mode, the subclass must *not* call this function.
+    Since many decoders only provide a callback for when the looping occurs,
+    and that looping occurs inside the decoding operation itself, the following
+    mechanism for subclass is suggested: set a flag inside such a callback.
+    Then, in the next @decode call, before doing the decoding, check this flag.
+    If it is set, gst_nonstream_audio_decoder_handle_loop() is called, and the
+    flag is cleared.
+    (This function call is necessary in LOOPING mode because it updates the
+    current segment and makes sure the next buffer that is sent downstream
+    has its DISCONT flag set.)
+  - When the current subsong is switched, @set_current_subsong is called.
+    If it fails, a warning is reported, and nothing else is done. Otherwise,
+    it calls @get_subsong_duration to get the new current subsongs's
+    duration, @get_subsong_tags to get its tags, reports a new duration
+    (i.e. it sends a duration event downstream and generates a duration
+    message), updates the current segment, and sends the subsong's tags in
+    an event downstream. (If @set_current_subsong has been set to NULL by
+    the subclass, attempts to set a current subsong are ignored; likewise,
+    if @get_subsong_duration is NULL, no duration is reported, and if
+    @get_subsong_tags is NULL, no tags are sent downstream.)
+  - When an attempt is made to switch the output mode, it is checked against
+    the bitmask returned by @get_supported_output_modes. If the proposed
+    new output mode is supported, the current segment is updated
+    (it is open-ended in STEADY mode, and covers the (sub)song length in
+    LOOPING mode), and the subclass' @set_output_mode function is called
+    unless it is set to NULL. Subclasses should reset internal loop counters
+    in this function.
+
+The relationship between (sub)song duration, output mode, and number of loops
+is defined this way (this is all done by the base class automatically):
+
+* Segments have their duration and stop values set to GST_CLOCK_TIME_NONE in
+  STEADY mode, and to the duration of the (sub)song in LOOPING mode.
+
+* The duration that is returned to a DURATION query is always the duration
+  of the (sub)song, regardless of number of loops or output mode. The same
+  goes for DURATION messages and tags.
+
+* If the number of loops is &gt;0 or -1, durations of TOC entries are set to
+  the duration of the respective subsong in LOOPING mode and to G_MAXINT64 in
+  STEADY mode. If the number of loops is 0, entry durations are set to the
+  subsong duration regardless of the output mode.</doc>

+
+This is useful for when the subclass wishes to adjust one or more output
+parameters to whatever downstream is supporting. For example, the output
+sample rate is often a freely adjustable value in module players.
+
+This function tries to find a value inside the srcpad peer's caps for
+@format, @sample_rate, @num_chnanels . Any of these can be NULL; they
+(and the corresponding downstream caps) are then skipped while retrieving
+information. Non-fixated caps are fixated first; the value closest to
+their present value is then chosen. For example, if the variables pointed
+to by the arguments are GST_AUDIO_FORMAT_16, 48000 Hz, and 2 channels,
+and the downstream caps are:
+
+"audio/x-raw, format={S16LE,S32LE}, rate=[1,32000], channels=[1,MAX]"
+
+Then @format and @channels stay the same, while @sample_rate is set to 32000 Hz.
+This way, the initial values the the variables pointed to by the arguments
+are set to can be used as default output values. Note that if no downstream
+caps can be retrieved, then this function does nothing, therefore it is
+necessary to ensure that @format, @sample_rate, and @channels have valid
+initial values.
+
+Decoder lock is not held by this function, so it can be called from within
+any of the class vfuncs.</doc>

+      <doc xml:space="preserve" filename="../subprojects/gst-plugins-bad/gst-libs/gst/audio/gstnonstreamaudiodecoder.h">Subclasses can override any of the available optional virtual methods or not, as
+needed. At minimum, @load_from_buffer (or @load_from_custom), @get_supported_output_modes,
+and @decode need to be overridden.
+
+All functions are called with a locked decoder mutex.
+
+&gt; If GST_ELEMENT_ERROR, GST_ELEMENT_WARNING, or GST_ELEMENT_INFO are called from
+&gt; inside one of these functions, it is strongly recommended to unlock the decoder mutex
+&gt; before and re-lock it after these macros to prevent potential deadlocks in case the
+&gt; application does something with the element when it receives an ERROR/WARNING/INFO
+&gt; message. Same goes for gst_element_post_message() calls and non-serialized events.
+
+By default, this class works by reading media data from the sinkpad, and then commencing
+playback. Some decoders cannot be given data from a memory block, so the usual way of
+reading all upstream data and passing it to @load_from_buffer doesn't work then. In this case,
+set the value of loads_from_sinkpad to FALSE. This changes the way this class operates;
+it does not require a sinkpad to exist anymore, and will call @load_from_custom instead.
+One example of a decoder where this makes sense is UADE (Unix Amiga Delitracker Emulator).
+For some formats (such as TFMX), it needs to do the file loading by itself.
+Since most decoders can read input data from a memory block, the default value of
+loads_from_sinkpad is TRUE.</doc>

+      <doc xml:space="preserve" filename="../subprojects/gstreamer/libs/gst/base/gstadapter.c">This class is for elements that receive buffers in an undesired size.
+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>

+Control is given to the subclass when all pads have data.
+
+ * Base class for mixers and muxers. Subclasses should at least implement
+   the #GstAggregatorClass::aggregate virtual method.
+
+ * Installs a #GstPadChainFunction, a #GstPadEventFullFunction and a
+   #GstPadQueryFunction to queue all serialized data packets per sink pad.
+   Subclasses should not overwrite those, but instead implement
+   #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.
+   In addition, if the gap event was flagged with GST_GAP_FLAG_MISSING_DATA,
+   a custom meta is added to the resulting gap buffer (GstAggregatorMissingDataMeta).
+
+ * Subclasses must use (a subclass of) #GstAggregatorPad for both their
+   sink and source pads.
+   See gst_element_class_add_static_pad_template_with_gtype().
+
+This class used to live in gst-plugins-bad and was moved to core.</doc>

+      <doc xml:space="preserve" filename="../subprojects/gstreamer/libs/gst/base/gstbaseparse.c">This base class is for parser elements that process data and splits it
+into separate audio/video/whatever frames.
+
+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>

+      <doc xml:space="preserve" filename="../subprojects/gstreamer/libs/gst/base/gstbasesink.c">#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;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>

+      <doc xml:space="preserve" filename="../subprojects/gstreamer/libs/gst/base/gstbasesrc.c">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;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>

+      <doc xml:space="preserve" filename="../subprojects/gstreamer/libs/gst/base/gstbasetransform.c">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>

+
+  * 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.

+#GstElement&lt;!-- --&gt;s that have multiple source pads and need to combine
+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
+default GST_FORMAT_BYTES format of #GstBaseSrc.
+
+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.

+      <doc xml:space="preserve" filename="../subprojects/gstreamer/libs/gst/check/gstharness.c">#GstHarness is meant to make writing unit test for GStreamer much easier.
+It can be thought of as a way of treating a #GstElement as a black box,
+deterministically feeding it data, and controlling what data it outputs.
+
+The basic structure of #GstHarness is two "floating" #GstPads that connect
+to the harnessed #GstElement src and sink #GstPads like so:
+
+|[
+          __________________________
+ _____   |  _____            _____  |   _____
+|     |  | |     |          |     | |  |     |
+| src |--+-| sink|  Element | src |-+--| sink|
+|_____|  | |_____|          |_____| |  |_____|
+         |__________________________|
+
+]|
+
+With this, you can now simulate any environment the #GstElement might find
+itself in. By specifying the #GstCaps of the harness #GstPads, using
+functions like gst_harness_set_src_caps() or gst_harness_set_sink_caps_str(),
+you can test how the #GstElement interacts with different caps sets.
+
+Your harnessed #GstElement can of course also be a bin, and using
+gst_harness_new_parse() supporting standard gst-launch syntax, you can
+easily test a whole pipeline instead of just one element.
+
+You can then go on to push #GstBuffers and #GstEvents on to the srcpad,
+using functions like gst_harness_push() and gst_harness_push_event(), and
+then pull them out to examine them with gst_harness_pull() and
+gst_harness_pull_event().
+
+## A simple buffer-in buffer-out example
+
+|[&lt;!-- language="C" --&gt;
+  #include &lt;gst/gst.h&gt;
+  #include &lt;gst/check/gstharness.h&gt;
+  GstHarness *h;
+  GstBuffer *in_buf;
+  GstBuffer *out_buf;
+
+  // attach the harness to the src and sink pad of GstQueue
+  h = gst_harness_new ("queue");
+
+  // we must specify a caps before pushing buffers
+  gst_harness_set_src_caps_str (h, "mycaps");
+
+  // create a buffer of size 42
+  in_buf = gst_harness_create_buffer (h, 42);
+
+  // push the buffer into the queue
+  gst_harness_push (h, in_buf);
+
+  // pull the buffer from the queue
+  out_buf = gst_harness_pull (h);
+
+  // validate the buffer in is the same as buffer out
+  fail_unless (in_buf == out_buf);
+
+  // cleanup
+  gst_buffer_unref (out_buf);
+  gst_harness_teardown (h);
+
+  ]|
+
+Another main feature of the #GstHarness is its integration with the
+#GstTestClock. Operating the #GstTestClock can be very challenging, but
+#GstHarness simplifies some of the most desired actions a lot, like wanting
+to manually advance the clock while at the same time releasing a #GstClockID
+that is waiting, with functions like gst_harness_crank_single_clock_wait().
+
+#GstHarness also supports sub-harnesses, as a way of generating and
+validating data. A sub-harness is another #GstHarness that is managed by
+the "parent" harness, and can either be created by using the standard
+gst_harness_new type functions directly on the (GstHarness *)-&gt;src_harness,
+or using the much more convenient gst_harness_add_src() or
+gst_harness_add_sink_parse(). If you have a decoder-element you want to test,
+(like vp8dec) it can be very useful to add a src-harness with both a
+src-element (videotestsrc) and an encoder (vp8enc) to feed the decoder data
+with different configurations, by simply doing:
+
+|[&lt;!-- language="C" --&gt;
+  GstHarness * h = gst_harness_new ("vp8dec");
+  gst_harness_add_src_parse (h, "videotestsrc is-live=1 ! vp8enc", TRUE);
+]|
+
+and then feeding it data with:
+
+|[&lt;!-- language="C" --&gt;
+gst_harness_push_from_src (h);

+#GstClock allows for setting up single shot or periodic clock notifications
+as well as waiting for these notifications synchronously (using
+gst_clock_id_wait()) or asynchronously (using gst_clock_id_wait_async() or
+gst_clock_id_wait_async()). This is used by many GStreamer elements,
+among them #GstBaseSrc and #GstBaseSink.
+
+#GstTestClock keeps track of these clock notifications. By calling
+gst_test_clock_wait_for_next_pending_id() or
+gst_test_clock_wait_for_multiple_pending_ids() a unit tests may wait for the
+next one or several clock notifications to be requested. Additionally unit
+tests may release blocked waits in a controlled fashion by calling
+gst_test_clock_process_next_clock_id(). This way a unit test can control the
+inaccuracy (jitter) of clock notifications, since the test can decide to
+release blocked waits when the clock time has advanced exactly to, or past,
+the requested clock notification time.
+
+There are also interfaces for determining if a notification belongs to a
+#GstTestClock or not, as well as getting the number of requested clock
+notifications so far.
+
+N.B.: When a unit test waits for a certain amount of clock notifications to
+be requested in gst_test_clock_wait_for_next_pending_id() or
+gst_test_clock_wait_for_multiple_pending_ids() then these functions may block
+for a long time. If they block forever then the expected clock notifications
+were never requested from #GstTestClock, and so the assumptions in the code
+of the unit test are wrong. The unit test case runner in gstcheck is
+expected to catch these cases either by the default test case timeout or the
+one set for the unit test by calling tcase_set_timeout\(\).
+
+The sample code below assumes that the element under test will delay a
+buffer pushed on the source pad by some latency until it arrives on the sink
+pad. Moreover it is assumed that the element will at some point call
+gst_clock_id_wait() to synchronously wait for a specific time. The first
+buffer sent will arrive exactly on time only delayed by the latency. The
+second buffer will arrive a little late (7ms) due to simulated jitter in the
+clock notification.

+of the limitation on OpenGL context, this object is not thread safe unless
+specified and must only be activated in a single thread.
+
+Environment variables:
+- `GST_GL_API`: select which OpenGL API to create and OpenGL context for.
+                Depending on the platform, the available values are
+                'opengl', 'opengl3' (core profile), and 'gles2'.  See the
+                the #GstGLAPI enumeration for more details.
+- `GST_GL_PLATFORM`: select which OpenGL platform to create an OpenGL
+                     context with.  Depending on the platform and the
+                     dependencies available build-time, the available values
+                     are, 'glx', 'egl', 'cgl', 'wgl', and 'eagl'
+- `GST_GL_CONFIG`: select the configuration used for creating the OpenGL
+                   context and OpenGL surface.  Written out as a GstStructure
+                   that has been serialized to string.  e.g.
+                   `GST_GL_CONFIG="gst-gl-context-config,red-size=8,green-size=8,blue-size=8,alpha-size=8,depth-size=16"`.
+                   Not all platforms will support the same level of
+                   functionality.</doc>

+Elements are required to make use of #GstContext to share and propagate
+a #GstGLDisplay.
+
+There are a number of environment variables that influence the choice of
+platform and window system specific functionality.
+- GST_GL_WINDOW influences the window system to use.  Common values are
+  'x11', 'wayland', 'win32' or 'cocoa'.
+- GST_GL_PLATFORM influences the OpenGL platform to use.  Common values are
+  'egl', 'glx', 'wgl' or 'cgl'.
+- GST_GL_API influences the OpenGL API requested by the OpenGL platform.
+  Common values are 'opengl', 'opengl3' and 'gles2'.
+
+&gt; Certain window systems require a special function to be called to
+&gt; initialize threading support.  As this GStreamer GL library does not preclude
+&gt; concurrent access to the windowing system, it is strongly advised that
+&gt; applications ensure that threading support has been initialized before any
+&gt; other toolkit/library functionality is accessed.  Failure to do so could
+&gt; result in sudden application abortion during execution.  The most notably
+&gt; example of such a function is X11's XInitThreads\().</doc>

+
+The %GstMpegtsSection object is the representation of MPEG-TS Section (SI or
+PSI).
+
+Various elements can post those on the bus via %GstMessage of type
+%GST_MESSAGE_ELEMENT. The gst_message_parse_mpegts_section() function
+provides access to the section.
+
+Applications (or other elements) can create them either by using one of the
+`gst_mpegts_section_from_*` functions, or by providing the raw SI data via
+gst_mpegts_section_new().
+
+Elements outputting MPEG-TS streams can also create sections using the
+various convenience functions and then get the packetized data (to be
+inserted in MPEG-TS packets) using gst_mpegts_section_packetize().
+
+For more details, refer to the ITU H.222.0 or ISO/IEC 13818-1 specifications
+and other specifications mentioned in the documentation.
+
+# Supported base MPEG-TS sections
+These are the sections for which parsing and packetizing code exists.

+A new clock is created with gst_net_client_clock_new() or

+This clock will poll the time provider and will update its calibration

+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
+GstPtpClock::internal-clock property will become non-NULL. You can

+The blocking mode just requires calling gst_discoverer_discover_uri()

+
+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()).

+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>

+')'.
+
+The description should return a pipeline with a single depayloader named

+all possible, complete RTP caps that are going to be supported. At least
+the payload type, clock-rate and encoding-name need to be specified.

+      <doc xml:space="preserve" filename="../subprojects/gst-plugins-base/gst-libs/gst/tag/gsttagdemux.c">Provides a base class for demuxing tags at the beginning or end of a
+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>

+      <doc xml:space="preserve" filename="../subprojects/gst-plugins-base/gst-libs/gst/tag/tags.c">Helper function for tag-reading plugins to create a #GstSample suitable to
+add to a #GstTagList as an image tag (such as #GST_TAG_IMAGE or
+#GST_TAG_PREVIEW_IMAGE) from the encoded image data and an (optional) image
+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>

+related 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&#8217;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 &#8216;0000&#8217; 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>

+      <doc xml:space="preserve" filename="../subprojects/gst-plugins-base/gst-libs/gst/video/gstvideodecoder.c">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.
+  * When the subclass enables the subframe mode with `gst_video_decoder_set_subframe_mode`,
+    the base class will provide to the subclass the same input frame with
+    different input buffers to the subclass @handle_frame
+    callback. During this call, the subclass needs to take
+    ownership of the input_buffer as @GstVideoCodecFrame.input_buffer
+    will have been changed before the next subframe buffer is received.
+    The subclass will call `gst_video_decoder_have_last_subframe`
+    when a new input frame can be created by the base class.
+    Every subframe will share the same @GstVideoCodecFrame.output_buffer
+    to write the decoding result. The subclass is responsible to protect
+    its access.
+
+  * If codec processing results in decoded data, the subclass should call
+    @gst_video_decoder_finish_frame to have decoded data pushed
+    downstream. In subframe mode
+    the subclass should call @gst_video_decoder_finish_subframe until the
+    last subframe where it should call @gst_video_decoder_finish_frame.
+    The subclass can detect the last subframe using GST_VIDEO_BUFFER_FLAG_MARKER
+    on buffers or using its own logic to collect the subframes.
+    In case of decoding failure, the subclass must call
+    @gst_video_decoder_drop_frame or @gst_video_decoder_drop_subframe,
+    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>

+
+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

+The subclass can signal via @flags how the frames until the next sync point

+    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

+      <doc xml:space="preserve" filename="../subprojects/gst-plugins-base/gst-libs/gst/video/gstvideoencoder.c">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>

+The purpose of this function is to make it easy for you to get to the video
+pixels in a generic way, without you having to worry too much about details
+such as whether the video data is allocated in one contiguous memory chunk
+or multiple memory chunks (e.g. one for each plane); or if custom strides
+and custom plane offsets are used or not (as signalled by GstVideoMeta on
+each buffer). This function will just fill the #GstVideoFrame structure
+with the right values and if you use the accessor macros everything will
+just work and you can access the data easily. It also maps the underlying
+memory chunks for you.</doc>

+      <doc xml:space="preserve" filename="../subprojects/gst-plugins-base/gst-libs/gst/video/videooverlay.c">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>
