Description Gwenole Beauchesne 2015-02-02 12:19:04 UTC 
Add support for video/x-raw(memory:EGLImage) outputs from vaapidecode or vaapipostproc so that simple downstream elements could directly provide a bufferpool of EGLImage, or absorb EGLImage from VA decoders or video processors.
Comment 1 Julien Isorce 2015-04-10 10:42:53 UTC 
Just to let you know I have started it though I cannot continue because it requires that the backend provides vaCreateSurface2 (http://cgit.freedesktop.org/libva/tree/va/va.c#n864). And libva's vdpau-driver does not provide it. Note that I have a nvidia card.

Or someone needs to implement vaCreateSurface2 in va state tracker in gallium: http://cgit.freedesktop.org/mesa/mesa/tree/src/gallium/state_trackers/va/context.c#n39
but first the decoding needs to be fixed: https://bugs.freedesktop.org/show_bug.cgi?id=89969

This might be interesting:

gl: implement GstGLMemoryEGL (bug #760916)

This is not implemented and merged in Mesa.

This is now fixed and merged in Mesa.

Yep it will be useful.

I have no plan to continue on this issue for now. Since in the end I used vaAcquireBufferHandle -> eglimage /dmabuf for my needs.
But still this feature would be great.
