I know this mail isn't helpful but reading above and remembering how
nice vdpau worked (already) many years ago and remembering how
people said at the time that vaapi is much superior over vdpau I still
wonder if we (FFmpeg) shouldn't have fought vaapi much stronger...

Sorry for the rant, Carl Eugen
