Why not create a test program that decodes video with vdpau, then reads
the resulting video frame, and writes it to stdout? I don't think it
can be avoided to test this on real hardware.

Putting it into ffmpeg.c sounds pretty evil, though.

Ideally you could add a filter to lavfi that converts vdpau surfaces to
software surfaces, but I think this would require nasty hacks due to
how the hwaccel architecture works.
