| <a name="id-1.2.33.9.5"></a><h3>Usage</h3> |
| <p> |
| A playbin element can be created just like any other element using |
| <a href="/usr/share/gtk-doc/html/gstreamer-1.0GstElementFactory.html#gst-element-factory-make"><code class="function">gst_element_factory_make()</code></a>. The file/URI to play should be set via the <a class="link" href="gst-plugins-base-plugins-playbin.html#GstPlayBin--uri" title="The “uri” property"><span class="type">“uri”</span></a> |
| 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 <a href="/usr/share/gtk-doc/html/gstreamer-1.0GstPipeline.html#GstPipeline-struct"><span class="type">GstPipeline</span></a>. It will notify the application of everything |
| that's happening (errors, end of stream, tags found, state changes, etc.) |
| by posting messages on its <a href="/usr/share/gtk-doc/html/gstreamer-1.0GstBus.html#GstBus-struct"><span class="type">GstBus</span></a>. The application needs to watch the |
| bus. |
| |
| Playback can be initiated by setting the element to PLAYING state using |
| <a href="/usr/share/gtk-doc/html/gstreamer-1.0GstElement.html#gst-element-set-state"><code class="function">gst_element_set_state()</code></a>. 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 <a class="link" href="gst-plugins-base-plugins-playbin.html#GstPlayBin--uri" title="The “uri” property"><span class="type">“uri”</span></a> property should be set to the |
| new location and then playbin be set to PLAYING state again. |
| |
| Seeking can be done using <a href="/usr/share/gtk-doc/html/gstreamer-1.0GstElement.html#gst-element-seek-simple"><code class="function">gst_element_seek_simple()</code></a> or <a href="/usr/share/gtk-doc/html/gstreamer-1.0GstElement.html#gst-element-seek"><code class="function">gst_element_seek()</code></a> |
| 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 <a href="/usr/share/gtk-doc/html/gstreamer-1.0GstElement.html#gst-element-get-state"><code class="function">gst_element_get_state()</code></a> 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 <a href="/usr/share/gtk-doc/html/gstreamer-1.0GstElement.html#gst-element-query-position"><code class="function">gst_element_query_position()</code></a> and <a href="/usr/share/gtk-doc/html/gstreamer-1.0GstElement.html#gst-element-query-duration"><code class="function">gst_element_query_duration()</code></a> 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. |
| </p> |

| <div class="refsect2"> |
| <a name="id-1.2.33.9.6"></a><h3>Advanced Usage: specifying the audio and video sink</h3> |
| <p> |
| By default, if no audio sink or video sink has been specified via the |
| <a class="link" href="gst-plugins-base-plugins-playbin.html#GstPlayBin--audio-sink" title="The “audio-sink” property"><span class="type">“audio-sink”</span></a> or <a class="link" href="gst-plugins-base-plugins-playbin.html#GstPlayBin--video-sink" title="The “video-sink” property"><span class="type">“video-sink”</span></a> 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 <a href="/usr/share/gtk-doc/html/gstreamer-1.0GstElementFactory.html#gst-element-factory-make"><code class="function">gst_element_factory_make()</code></a>) and provide them to playbin using the |
| <a class="link" href="gst-plugins-base-plugins-playbin.html#GstPlayBin--audio-sink" title="The “audio-sink” property"><span class="type">“audio-sink”</span></a> or <a class="link" href="gst-plugins-base-plugins-playbin.html#GstPlayBin--video-sink" title="The “video-sink” property"><span class="type">“video-sink”</span></a> 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 <a href="/usr/share/gtk-doc/html/gstreamer-1.0GstBin.html#GstBin-struct"><span class="type">GstBin</span></a> and putting elements in there and |
| linking them, and then creating a sink <a href="/usr/share/gtk-doc/html/gstreamer-1.0GstGhostPad.html#GstGhostPad-struct"><span class="type">GstGhostPad</span></a> 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!). |

| <a name="id-1.2.33.9.7"></a><h3>Retrieving Tags and Other Meta Data</h3> |
| <p> |
| 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. |

| <a name="id-1.2.33.9.8"></a><h3>Buffering</h3> |
| 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: |

| </table> |
| </div> |
| |
| 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). |

| <div class="refsect2"> |
| <a name="id-1.2.33.9.9"></a><h3>Embedding the video window in your application</h3> |
| 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 <a href="../html/gst-plugins-base-libs-gstvideooverlay.html#GstVideoOverlay-struct"><span class="type">GstVideoOverlay</span></a> interface, which most |
| video sinks implement. See the documentation there for more details. |
| </div> |
| <hr> |
| <div class="refsect2"> |
| <a name="id-1.2.33.9.10"></a><h3>Specifying which CD/DVD device to use</h3> |
| 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] |
| </div> |
| <hr> |
| <div class="refsect2"> |
| <a name="id-1.2.33.9.11"></a><h3>Handling redirects</h3> |
| <p> |
| 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. |

| <p>This signal is emitted when a new element is added to playbin or any of |
| its sub-bins. This signal can be used to configure elements, e.g. to set |
| properties on decoders. This is functionally equivalent to connecting to |
| the deep-element-added signal, but more convenient.</p> |
| <p>This signal is usually emitted from the context of a GStreamer streaming |
| thread, so might be called at the same time as code running in the main |
| application thread.</p> |
