|

|
|

* </para>
|
|
||||||
* <para>
|
|
||||||
* Along with implementing the interface, elements will need to query
|
|
||||||
* neighboor elements or send message to the application when preparing
|
|
||||||
* the context (see gst_video_context_prepare()). They also need to reply
|
|
||||||
* to the neighboors element queries, so the context can be shared without
|
|
||||||
* the application help.
|
|
||||||
* </para>
|
|

* <para>
|
|
||||||
* Elements that are guarantied to have both upstream and downstream
|

||||||
* neighboors element implementing the #GstVideoContext (like the gloverlay
|
|
||||||
* element in gst-plugins-opengl) is not required to also implement the

* interface. Relying on neighboors query shall be sufficient (see

|
|
||||||
* <para>
|
|

* The query is an application query with a structure name set to
|
|
||||||
* "prepare-video-context" and an array of supported video context types set
|
|
||||||
* in the field named "types". This query shall be send downstream and
|
|
||||||
* upstream, iterating the pads in order to find neighboors regardless of a
|
|
||||||
* static (sink to src) or a dynamic (src to sink) activation. Element should
|
|
||||||
* used the helpers method gst_video_context_prepare() (or
|
|
||||||
* gst_video_context_run_query() if no GstVideoContext interface) to
|
|
||||||
* correctly execute the query . The result is set using the query helper

|
|
||||||
* </para>
|
|
||||||
* <para>
|
|
||||||
* If the query is not handled by any neighboor, the element should ask the
|
|
||||||
* application using the "prepare-video-context" message. The application
|
|
||||||
* may then use the interface to set the video context information. If no
|
|
||||||
* context was set, the element shall create one using default configuration.

|
|
||||||
* <para>
|
|
||||||
* In the case there is no neighboor element with video context to share,
|
|
||||||
* the element will first turn toward the application, by sending a
|
|
||||||
* "prepare-video-context" message. This message is sent along with a list
|
|
||||||
* of supported display types. The application can optionally reply to this
|
|
||||||
* message by calling appropriate setter through the #GstVideoContext
|
|
||||||
* interface. If the application supports more then one video context type,
|
|
||||||
* it should choose the first one to occure in the supported list. It's
|
|
||||||
* important to remember that the message is delivered from the streaming
|
|
||||||
* thread, and appropriate locking should be considered. If the application
|
|
||||||
* does not have a video context to share, the element will simply allocate
|
|
||||||
* one base on default settings. Usually, only applications using OpenGL
|
|
||||||
* base sink, or running on special X11 display need to share a video context.
|
|
||||||
* <note>
|
|
||||||
* Applications sharing X11 Display structure should always initialize the
|
|
||||||
* X11 threading support using XInitThreads() as GStreamer will need to
|
|
||||||
* manipulate the display from a separeate threads.
