| virtual function for retrieving the GstVaapiDisplay created by the downstream sink element. The implementation of that virtual function is required for all Gstreamer/VAAPI sink elements. |
GstVaapiDisplay * gst_vaapi_video_sink_get_display (GstVaapiVideoSink *sink);
Returns the GstVaapiDisplay created by the VA-API sink element.
|
a GstElement |
Returns : |
the GstVaapiDisplay created by the sink element |
GstVaapiVideoSink * gst_vaapi_video_sink_lookup (GstElement *element);
Traverses the whole downstream elements chain and finds a suitable GstVaapiDisplay. This is a helper function for intermediate VA-API elements that don't create a GstVaapiDisplay but require one. e.g. the `vaapiconvert' element.
|
a GstElement |
Returns : |
the GstVaapiDisplay created by a downstream sink
element, or NULL if none was found |
