I can't help you with the VDPAU issue, but I assume you created a new
playback profile for VAAPI with only one entry with no resolution
conditions (or just everything larger than 0,0), correct? You should
see what vainfo reports--that might give some clues. Check the other
intel/VAAPI thread for details about the drivers and library versions
I have installed and make sure you have at least all the required
packages. Also make sure your GUI painter is set to Auto or OpenGL or
VAAPI won't work.
