I just got hit by this bug completely randomly. I did not wanted hardware acceleration, I just wanted to play some video and got black screen. It just happened that previously I had installed ubuntu-restricted-extras which automatically installs this vaapi thing. After I uninstalled ubuntu-restricted-extras i got my picture back.
