| * SECTION:element-playbin |
| * @title: playbin |
| * |
| * Playbin provides a stand-alone everything-in-one abstraction for an |
| * audio and/or video player. |
| * |
| * Playbin can handle both audio and video files and features |
| * |
| * * automatic file type recognition and based on that automatic |
| * selection and usage of the right audio/video/subtitle demuxers/decoders |
| * * visualisations for audio files |
| * * subtitle support for video files. Subtitles can be store in external |
| * files. |
| * * stream selection between different video/audio/subtitles streams |
| * * meta info (tag) extraction |
| * * easy access to the last video sample |
| * * buffering when playing streams over a network |
| * * volume control with mute option |
| * |
| * ## Usage |
| * |
| * 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 #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 |
| * |
| * 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. |
| * |
| * 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. |
| * |
| * 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 #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 |
| * call returns the seek will most likely still be in process. An application |
| * 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. |
| * |
| * 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. |
| * |
| * ## Advanced Usage: specifying the audio and video sink |
| * |
| * By default, if no audio sink or video sink has been specified via the |
| * #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. |
| * |
| * 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 |
| * #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 configuration dialog. |
| * |
| * 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 |
| * can be achieved by creating a #GstBin and putting elements in there and |
| * linking them, and then creating a sink #GstGhostPad for the bin and pointing |
| * 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. |
| * |
| * 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!). |
| * |
| * ## Retrieving Tags and Other Meta Data |
| * |
| * Most of the common meta data (artist, title, etc.) can be retrieved by |
| * watching for TAG messages on the pipeline's bus (see above). |
| * |
| * Other more specific meta information like width/height/framerate of video |
| * streams or samplerate/number of channels of audio streams can be obtained |
| * from the negotiated caps on the sink pads of the sinks. |
| * |
| * ## Buffering |
| * 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: |
| * |[ |
| * switch (GST_MESSAGE_TYPE (msg)) { |
| * case GST_MESSAGE_BUFFERING: { |
| * gint percent = 0; |
| * gst_message_parse_buffering (msg, &percent); |
| * g_print ("Buffering (%u percent done)", percent); |
| * break; |
| * } |
| * ... |
| * } |
| * ]| |
| * |
| * 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). |
| * |
| * ## Embedding the video window in your application |
| * 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 #GstVideoOverlay interface, which most |
| * video sinks implement. See the documentation there for more details. |
| * |
| * ## Specifying which CD/DVD device to use |
| * The device to use for CDs/DVDs needs to be set on the source element |
| * playbin creates before it is opened. The most generic way of doing this |
| * is to connect to playbin's "source-setup" (or "notify::source") signal, |
| * which will be emitted by playbin when it has created the source element |
| * for a particular URI. In the signal callback you can check if the source |
| * element has a "device" property and set it appropriately. In some cases |
| * the device can also be set as part of the URI, but it depends on the |
| * elements involved if this will work or not. For example, for DVD menu |
| * playback, the following syntax might work (if the resindvd plugin is used): |
| * dvd://[/path/to/device] |
| * |
| * ## Handling redirects |
| * |
| * Some elements may post 'redirect' messages on the bus to tell the |
| * application to open another location. These are element messages containing |
| * a structure named 'redirect' along with a 'new-location' field of string |
| * type. The new location may be a relative or an absolute URI. Examples |
| * for such redirects can be found in many quicktime movie trailers. |
| * |
| * ## Examples |
| * |[ |
| * gst-launch-1.0 -v playbin uri=file:///path/to/somefile.mp4 |
| * ]| |
| * This will play back the given AVI video file, given that the video and |
| * audio decoders required to decode the content are installed. Since no |
| * special audio sink or video sink is supplied (via playbin's audio-sink or |
| * video-sink properties) playbin will try to find a suitable audio and |
| * video sink automatically using the autoaudiosink and autovideosink elements. |
| * |[ |
| * gst-launch-1.0 -v playbin uri=cdda://4 |
| * ]| |
| * This will play back track 4 on an audio CD in your disc drive (assuming |
| * the drive is detected automatically by the plugin). |
| * |[ |
| * gst-launch-1.0 -v playbin uri=dvd:// |
| * ]| |
| * This will play back the DVD in your disc drive (assuming |
| * the drive is detected automatically by the plugin). |
