[Libva] Combining libva with OpenGL code

[Paul A. Steckler]

Is there a principled way to combine libva and with OpenGL code, when running
in an X11 window?

Say, for example, I want to decode a video in an X window, and draw
some things either
over or beside that video in the same window.

If there's sample code on how to do this, that would be very helpful.
