* <title>Usage</title>
* <para>
* A playbin element can be created just like any other element using
- * gst_element_factory_make(). The file/URI to play should be set via the "uri"
+ * gst_element_factory_make(). The file/URI to play should be set via the #GstPlayBin:uri
* property. This must be an absolute URI, relative file paths are not allowed.
* Example URIs are file:///home/joe/movie.avi or http://www.joedoe.com/foo.ogg
- * </para>
- * <para>
+ *
* Playbin is a #GstPipeline. It will notify the application of everything
* that's happening (errors, end of stream, tags found, state changes, etc.)
* by posting messages on its #GstBus. The application needs to watch the
* bus.
- * </para>
- * <para>
+ *
* Playback can be initiated by setting the element to PLAYING state using
* gst_element_set_state(). Note that the state change will take place in
* the background in a separate thread, when the function returns playback
* is probably not happening yet and any errors might not have occured yet.
* Applications using playbin should ideally be written to deal with things
* completely asynchroneous.
- * </para>
- * <para>
+ *
* When playback has finished (an EOS message has been received on the bus)
* or an error has occured (an ERROR message has been received on the bus) or
* the user wants to play a different track, playbin should be set back to
- * READY or NULL state, then the "uri" property should be set to the new
- * location and then playbin be set to PLAYING state again.
- * </para>
- * <para>
+ * READY or NULL state, then the #GstPlayBin:uri property should be set to the
+ * new location and then playbin be set to PLAYING state again.
+ *
* Seeking can be done using gst_element_seek_simple() or gst_element_seek()
* on the playbin element. Again, the seek will not be executed
* instantaneously, but will be done in a background thread. When the seek
* may wait for the seek to finish (or fail) using gst_element_get_state() with
* -1 as the timeout, but this will block the user interface and is not
* recommended at all.
- * </para>
- * <para>
+ *
* Applications may query the current position and duration of the stream
* via gst_element_query_position() and gst_element_query_duration() and
* setting the format passed to GST_FORMAT_TIME. If the query was successful,
* the duration or position will have been returned in units of nanoseconds.
* </para>

* <title>Advanced Usage: specifying the audio and video sink</title>
* <para>
* By default, if no audio sink or video sink has been specified via the
- * "audio-sink" or "video-sink" property, playbin will use the autoaudiosink
- * and autovideosink elements to find the first-best available output method.
+ * #GstPlayBin:audio-sink or #GstPlayBin:video-sink property, playbin will use
+ * the autoaudiosink and autovideosink elements to find the first-best
+ * available output method.
* This should work in most cases, but is not always desirable. Often either
* the user or application might want to specify more explicitly what to use
* for audio and video output.
- * </para>
- * <para>
+ *
* If the application wants more control over how audio or video should be
* output, it may create the audio/video sink elements itself (for example
* using gst_element_factory_make()) and provide them to playbin using the
- * "audio-sink" or "video-sink" property.
- * </para>
- * <para>
+ * #GstPlayBin:audio-sink or #GstPlayBin:video-sink property.
+ *
* GNOME-based applications, for example, will usually want to create
* gconfaudiosink and gconfvideosink elements and make playbin use those,
* so that output happens to whatever the user has configured in the GNOME
* Multimedia System Selector confinguration dialog.
- * </para>
- * <para>
+ *
* The sink elements do not necessarily need to be ready-made sinks. It is
* possible to create container elements that look like a sink to playbin,
* but in reality contain a number of custom elements linked together. This
* it to the sink pad of the first element within the bin. This can be used
* for a number of purposes, for example to force output to a particular
* format or to modify or observe the data before it is output.
- * </para>
- * <para>
+ *
* It is also possible to 'suppress' audio and/or video output by using
* 'fakesink' elements (or capture it from there using the fakesink element's
* "handoff" signal, which, nota bene, is fired from the streaming thread!).
* </para>
+ * </refsect2>
+ * <refsect2>
* <title>Retrieving Tags and Other Meta Data</title>
* <para>
* Most of the common meta data (artist, title, etc.) can be retrieved by
* watching for TAG messages on the pipeline's bus (see above).
- * </para>
- * <para>
+ *
* Other more specific meta information like width/height/framerate of video
* streams or samplerate/number of channels of audio streams can be obtained
- * using the "stream-info" property, which will return a GList of stream info
- * objects, one for each stream. These are opaque objects that can only be
- * accessed via the standard GObject property interface, ie. g_object_get().
+ * using the #GstPlayBaseBin:stream-info property, which will return a GList of
+ * stream info objects, one for each stream. These are opaque objects that can
+ * only be accessed via the standard GObject property interface, ie. g_object_get().
* Each stream info object has the following properties:
* <itemizedlist>
* <listitem>"object" (GstObject) (the decoder source pad usually)</listitem>
* <listitem>"language-code" (string) (ISO-639 language code for this stream, mostly used for audio/subtitle streams)</listitem>
* <listitem>"codec" (string) (format this stream was encoded in)</listitem>
* </itemizedlist>
- * Stream information from the stream-info properties is best queried once
+ * Stream information from the #GstPlayBaseBin:stream-info property is best queried once
* playbin has changed into PAUSED or PLAYING state (which can be detected
- * via a state-changed message on the bus where old_state=READY and
+ * via a state-changed message on the #GstBus where old_state=READY and
* new_state=PAUSED), since before that the list might not be complete yet or
* not contain all available information (like language-codes).
* </para>
- * <title>Buffering status</title>
- * <para>
- * Playbin handles buffering automatically. When playbin is buffering, it
- * will post BUFFERING messages on the bus with a percentage value that
- * shows the progress of the buffering. Applications may want to show this
- * information to the user in some form or another. Here is how to extract
- * the percentage information from the message:
- * </para>
- * <para>

+ * </refsect2>
+ * <refsect2>
+ * <title>Buffering</title>
+ * Playbin handles buffering automatically for the most part, but applications
+ * need to handle parts of the buffering process as well. Whenever playbin is
+ * buffering, it will post BUFFERING messages on the bus with a percentage
+ * value that shows the progress of the buffering process. Applications need
+ * to set playbin to PLAYING or PAUSED state in response to these messages.
+ * They may also want to convey the buffering progress to the user in some
+ * way. Here is how to extract the percentage information from the message
+ * (requires GStreamer >= 0.10.11):
+ * |[
* switch (GST_MESSAGE_TYPE (msg)) {
* case GST_MESSAGE_BUFFERING: {
* gint percent = 0;
- * gst_structure_get_int (msg->structure, "buffer-percent", &percent);
+ * gst_message_parse_buffering (msg, &percent);
* g_print ("Buffering (%%u percent done)", percent);
* break;
* }
* ...
* }
- * </programlisting>
- * Note that application should keep the pipeline in the PAUSED state when a
- * GST_MESSAGE_BUFFERING message is received with a buffer-percent < 100.
- * </para>
+ * ]|
+ * Note that applications should keep/set the pipeline in the PAUSED state when
+ * a BUFFERING message is received with a buffer percent value < 100 and set
+ * the pipeline back to PLAYING state when a BUFFERING message with a value
+ * of 100 percent is received (if PLAYING is the desired state, that is).

* <title>Embedding the video window in your application</title>
- * <para>
* By default, playbin (or rather the video sinks used) will create their own
* window. Applications will usually want to force output to a window of their
- * own, however. This can be done using the GstXOverlay interface, which most
+ * own, however. This can be done using the #GstXOverlay interface, which most
* video sinks implement. See the documentation there for more details.
- * </para>
+ * </refsect2>
+ * <refsect2>
* <title>Specifying which CD/DVD device to use</title>
- * <para>
* The device to use for CDs/DVDs needs to be set on the source element
* playbin creates before it is opened. The only way to do this at the moment
* is to connect to playbin's "notify::source" signal, which will be emitted
* property and set it appropriately. In future ways might be added to specify
* the device as part of the URI, but at the time of writing this is not
* possible yet.
- * </para>
+ * </refsect2>
+ * <refsect2>
* <title>Examples</title>
- * <para>
- * Here is a simple pipeline to play back a video or audio file:
- * <programlisting>

* gst-launch -v playbin uri=file:///path/to/somefile.avi
