Allow plain gst_buffer_map() interface to work with gstreamer-vaapi video buffers, i.e. expose the underlying GstVaapiSurfaceProxy to the caller. This is the only sensible enough thing to do in this mode as the underlying surface pixels need to be extracted through an explicit call to the gst_video_frame_map() function instead. A possible use-case of this is to implement a "handoff" signal handler to fakesink or identity element for further processing. |
