+      <doc xml:space="preserve">The Assets in the GStreamer Editing Services represent the resources
+that can be used. You can create assets for any type that implements the #GESExtractable
+interface, for example #GESClips, #GESFormatter, and #GESTrackElement do implement it.
+This means that assets will represent for example a #GESUriClips, #GESBaseEffect etc,
+and then you can extract objects of those types with the appropriate parameters from the asset
+using the #ges_asset_extract method:
+
+|[
+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));
+
+]|
+
+In that example, the advantages of having a #GESAsset are that you can know what effects
+you are working with and let your user know about the avalaible ones, you can add metadata
+to the #GESAsset through the #GESMetaContainer interface and you have a model for your
+custom effects. Note that #GESAsset management is making easier thanks to the #GESProject class.
+
+Each asset is represented by a pair of @extractable_type and @id (string). Actually the @extractable_type
+is the type that implements the #GESExtractable interface, that means that for example for a #GESUriClip,
+the type that implements the #GESExtractable interface is #GESClip.
+The identifier represents different things depending on the @extractable_type and you should check
+the documentation of each type to know what the ID of #GESAsset actually represents for that type. By default,
+we only have one #GESAsset per type, and the @id is the name of the type, but this behaviour is overriden
+to be more useful. For example, for GESTransitionClips, the ID is the vtype of the transition
+you will extract from it (ie crossfade, box-wipe-rc etc..) For #GESEffect the ID is the
+@bin-description property of the extracted objects (ie the gst-launch style description of the bin that
+will be used).
+
+Each and every #GESAsset is cached into GES, and you can query those with the #ges_list_assets function.
+Also the system will automatically register #GESAssets for #GESFormatters and #GESTransitionClips
+and standard effects (actually not implemented yet) and you can simply query those calling:
+|[
+   GList *formatter_assets, *tmp;
+
+   //  List all  the transitions
+   formatter_assets = ges_list_assets (GES_TYPE_FORMATTER);
+
+   // Print some infos about the formatter GESAsset
+   for (tmp = formatter_assets; tmp; tmp = tmp-&gt;next) {
+     g_print ("Name of the formatter: %s, file extension it produces: %s",
+       ges_meta_container_get_string (GES_META_CONTAINER (tmp-&gt;data), GES_META_FORMATTER_NAME),
+       ges_meta_container_get_string (GES_META_CONTAINER (tmp-&gt;data), GES_META_FORMATTER_EXTENSION));
+   }
+
+   g_list_free (transition_assets);
+
+]|
+
+You can request the creation of #GESAssets using either #ges_asset_request_async or
+#ges_asset_request_async. All the #GESAssets are cached and thus any asset that has already
+been created can be requested again without overhead.</doc>

+      <doc xml:space="preserve">#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.
+
+## Notes
+
+A #GstBin internally intercepts every #GstMessage posted by its children and
+implements the following default behaviour for each of them:
+
+* GST_MESSAGE_EOS: This message is only posted by sinks in the PLAYING
+state. If all sinks posted the EOS message, this bin will post and EOS
+message upwards.
+
+* GST_MESSAGE_SEGMENT_START: Just collected and never forwarded upwards.
+The messages are used to decide when all elements have completed playback
+of their segment.
+
+* GST_MESSAGE_SEGMENT_DONE: Is posted by #GstBin when all elements that posted
+a SEGMENT_START have posted a SEGMENT_DONE.
+
+* GST_MESSAGE_DURATION_CHANGED: Is posted by an element that detected a change
+in the stream duration. The default bin behaviour is to clear any
+cached duration values so that the next duration query will perform
+a full duration recalculation. 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.
+
+* GST_MESSAGE_CLOCK_LOST: This message is posted by an element when it
+can no longer provide a clock. The default bin behaviour is to
+check if the lost clock was the one provided by the bin. If so and
+the bin is currently in the PLAYING state, the message is forwarded to
+the bin parent.
+This message is also generated when a clock provider is removed from
+the bin. If this message is received by the application, it should
+PAUSE the pipeline and set it back to PLAYING to force a new clock
+distribution.
+
+* GST_MESSAGE_CLOCK_PROVIDE: This message is generated when an element
+can provide a clock. This mostly happens when a new clock
+provider is added to the bin. The default behaviour of the bin is to
+mark the currently selected clock as dirty, which will perform a clock
+recalculation the next time the bin is asked to provide a clock.
+This message is never sent tot the application but is forwarded to
+the parent of the bin.
+
+* OTHERS: posted upwards.
+
+A #GstBin implements the following default behaviour for answering to a
+#GstQuery:
+
+* GST_QUERY_DURATION:If the query has been asked before with the same format
+and the bin is a toplevel bin (ie. has no parent),
+use the cached previous value. If no previous value was cached, the
+query is sent to all sink elements in the bin and the MAXIMUM of all
+values is returned. If the bin is a toplevel bin the value is cached.

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

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

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

+Every #GstPipeline has one bus.

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

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

+Used when there is no explicit precedence of one caps over the other. e.g.
+tee's sink pad getcaps function, it will probe its src pad peers' for their
+caps and intersect them with this mode.
+
+@GST_CAPS_INTERSECT_FIRST is useful when an element wants to preserve
+another element's caps priority order when intersecting with its own caps.
+Example: If caps1 is [A, B, C] and caps2 is [E, B, D, A], the result
+would be [A, B], maintaining the first caps priority on the intersection.</doc>

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

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

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

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

+a threadsafe way.
+
+Various GStreamer objects provide access to their internal structures using
+an iterator.
+
+Note that if calling a GstIterator function results in your code receiving
+a refcounted object (with, say, g_value_get_object()), the refcount for that
+object will not be increased. Your code is responsible for taking a reference
+if it wants to continue using it later.
+
+The basic use pattern of an iterator is as follows:
+|[&lt;!-- language="C" --&gt;
+  GstIterator *it = _get_iterator(object);
+  GValue item = G_VALUE_INIT;
+  done = FALSE;
+  while (!done) {

+      case GST_ITERATOR_OK:

+        g_value_reset (&amp;amp;item);
+        break;
+      case GST_ITERATOR_RESYNC:

+        gst_iterator_resync (it);

+      <doc xml:space="preserve">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>

+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">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

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

+request a buffer at the specified @offset and @length. If this function
+returns #GST_FLOW_OK, the result buffer will be stored in @buffer. The
+contents of @buffer is invalid for any other return value.
+
+This function is installed on a source pad with
+gst_pad_set_getrange_function() and can only be called on source pads after
+they are successfully activated with gst_pad_activate_mode() with the
+#GST_PAD_MODE_PULL.
+
+@offset and @length are always given in byte units. @offset must normally be a value
+between 0 and the length in bytes of the data available on @pad. The
+length (duration in bytes) can be retrieved with a #GST_QUERY_DURATION or with a
+#GST_QUERY_SEEKING.
+
+Any @offset larger or equal than the length will make the function return
+#GST_FLOW_EOS, which corresponds to EOS. In this case @buffer does not
+contain a valid buffer.
+
+The buffer size of @buffer will only be smaller than @length when @offset is
+near the end of the stream. In all other cases, the size of @buffer must be
+exactly the requested size.
+
+It is allowed to call this function with a 0 @length and valid @offset, in
+which case @buffer will contain a 0-sized buffer and the function returns
+#GST_FLOW_OK.
+
+When this function is called with a -1 @offset, the sequentially next buffer
+of length @length in the stream is returned.
+
+When this function is called with a -1 @length, a buffer with a default
+optimal length is returned in @buffer. The length might depend on the value

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

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

+      <doc xml:space="preserve">A #GstPoll keeps track of file descriptors much like fd_set (used with
+select()) or a struct pollfd array (used with poll()). Once created with
+gst_poll_new(), the set can be used to wait for file descriptors to be
+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() and gst_poll_fd_ctl_write().
+
+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,
+gst_poll_fd_can_read() to see if it is possible to read from the file
+descriptor, and gst_poll_fd_can_write() to see if it is possible to

+      <doc xml:space="preserve">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 concidered as "app presets".</doc>

+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">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 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">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">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.
+
+Be aware that the current #GstCaps / #GstStructure serialization into string
+has limited support for nested #GstCaps / #GstStructure fields. It can only
+support one level of nesting. Using more levels will lead to unexpected
+behavior when using serialization features, such as gst_caps_to_string() or
+gst_value_serialize() and their counterparts.</doc>

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

+      <doc xml:space="preserve">#GstTask is used by #GstElement and #GstPad to provide the data passing
+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>

+        <doc xml:space="preserve">Create a new Task that will repeatedly call the provided @func
+with @user_data as a parameter. Typically the task will run in
+a new thread.
+
+The function cannot be changed after the task has been created. You
+must create a new #GstTask to change the function.
+
+This function will not yet create and start a thread. Use gst_task_start() or
+gst_task_pause() to create and start the GThread.
+
+Before the task can be used, a #GRecMutex must be configured using the
+gst_task_set_lock() function. This lock will always be acquired while
+@func is called.</doc>

+#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>

+      <doc xml:space="preserve">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

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

+a (subclass of) #GstAudioAggregatorConvertPad to use the default

+To allow for the output caps to change, the mechanism is the same as

+
+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

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

+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 implicitely means that this is a stereo stream with a front left and front right
+channel.</doc>

+      <doc xml:space="preserve">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.
+
+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">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>

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

+      <doc xml:space="preserve">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>

+      <doc xml:space="preserve">Manages a set of pads with the purpose of aggregating their buffers.
+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.
+
+ * 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.
+
+ * Same goes for EOS events, which should not be pushed directly by the
+   subclass, it should instead return GST_FLOW_EOS in its aggregate
+   implementation.
+
+ * Note that the aggregator logic regarding gap event handling is to turn
+   these into gap buffers with matching PTS and duration. It will also
+   flag these buffers with GST_BUFFER_FLAG_GAP and GST_BUFFER_FLAG_DROPPABLE
+   to ease their identification and subsequent processing.
+
+ * Subclasses must use (a subclass of) #GstAggregatorPad for both their
+   sink and source pads.
+   See gst_element_class_add_static_pad_template_with_gtype().
+
+This class used to live in gst-plugins-bad and was moved to core.</doc>

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

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

+      <doc xml:space="preserve">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 immediatelly from the gst_flow_combiner_update_flow() function.</doc>

+however, this function will use the specified function @func to obtain the
+data needed by the typefind functions, rather than operating on a given
+source pad. This is useful mostly for elements like tag demuxers which
+strip off data at the beginning and/or end of a file and want to typefind
+the stripped data stream before adding their own source pad (the specified
+callback can then call the upstream peer pad with offsets adjusted for the
+tag size, for example).
+
+When @extension is not %NULL, this function will first try the typefind
+functions for the given extension, which might speed up the typefinding
+in many cases.

+
+A new clock is created with gst_net_client_clock_new() or
+gst_ntp_clock_new(), which takes the address and port of the remote time
+provider along with a name and an initial time.
+
+This clock will poll the time provider and will update its calibration
+parameters based on the local and remote observations.
+
+The "round-trip" property limits the maximum round trip packets can take.
+
+Various parameters of the clock can be configured with the parent #GstClock
+"timeout", "window-size" and "window-threshold" object properties.
+
+A #GstNetClientClock and #GstNtpClock is typically set on a #GstPipeline with
+gst_pipeline_use_clock().

+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
+check this with gst_clock_wait_for_sync(), the GstClock::synced signal and

+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()).

+      <doc xml:space="preserve">Provides a base class for audio RTP payloaders for frame or sample based
+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>

+GST_BUFFER_PTS this can result in RTP timestamps that also don't increment
+with the amount of data in the payloaded packet. To circumvent this it is
+possible to set the perfect rtptime option enabled. When this option is
+enabled the payloader will increment the RTP timestamps based on
+GST_BUFFER_OFFSET which relates to the amount of data in each packet
+rather than the GST_BUFFER_PTS of each buffer and therefore the RTP
+timestamps will more closely correlate with the amount of data in each
+buffer. Currently GstRTPBasePayload is limited to handling perfect RTP
+timestamps for audio streams.</doc>

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

+
+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 #GST_TYPE_TAG_IMAGE_TYPE 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

+      <doc xml:space="preserve">The Navigation interface is used for creating and injecting navigation 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>

+frames.
+
+The GstVideoDecoder base class and derived subclasses should cooperate as
+follows:
+
+## Configuration
+
+  * Initially, GstVideoDecoder calls @start when the decoder element
+    is activated, which allows the subclass to perform any global setup.
+
+  * GstVideoDecoder calls @set_format to inform the subclass of caps
+    describing input video data that it is about to receive, including
+    possibly configuration data.
+    While unlikely, it might be called more than once, if changing input
+    parameters require reconfiguration.
+
+  * Incoming data buffers are processed as needed, described in Data
+    Processing below.
+
+  * GstVideoDecoder calls @stop at end of all processing.
+
+## Data processing
+
+    * The base class gathers input data, and optionally allows subclass
+      to parse this into subsequently manageable chunks, typically
+      corresponding to and referred to as 'frames'.
+
+    * Each input frame is provided in turn to the subclass' @handle_frame
+      callback.
+      The ownership of the frame is given to the @handle_frame callback.
+
+    * If codec processing results in decoded data, the subclass should call
+      @gst_video_decoder_finish_frame to have decoded data pushed.
+      downstream. Otherwise, the subclass must call
+      @gst_video_decoder_drop_frame, to allow the base class to do timestamp
+      and offset tracking, and possibly to requeue the frame for a later
+      attempt in the case of reverse playback.
+
+## Shutdown phase
+
+  * The GstVideoDecoder class calls @stop to inform the subclass that data
+    parsing will be stopped.
+
+## Additional Notes
+
+  * Seeking/Flushing
+
+    * When the pipeline is seeked or otherwise flushed, the subclass is
+      informed via a call to its @reset callback, with the hard parameter
+      set to true. This indicates the subclass should drop any internal data
+      queues and timestamps and prepare for a fresh set of buffers to arrive
+      for parsing and decoding.
+
+  * End Of Stream
+
+    * At end-of-stream, the subclass @parse function may be called some final
+      times with the at_eos parameter set to true, indicating that the element
+      should not expect any more data to be arriving, and it should parse and
+      remaining frames and call gst_video_decoder_have_frame() if possible.
+
+The subclass is responsible for providing pad template caps for
+source and sink pads. The pads need to be named "sink" and "src". It also
+needs to provide information about the ouptput 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>

+  * GstVideoEncoder calls @set_format to inform subclass of the format

+      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>

+      <doc xml:space="preserve">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 #plasink 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).

+  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 #GstOverlayComposition 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>
