There are wrappers to use VA-API as VDPAU (libvdpau-va-gl1) and have
it working with MPlayer.
Though for the normal use-cases (and at least if power draw is not
a major concern) hardware acceleration is just an unnecessary pain.
It's often slower (limited to e.g. 60 FPS when the CPU can easily do
300, which has some impact on seek performance for example), has
really pathetic error concealment, lacks many of the encoder bug
workarounds needed especially for MPEG-4 ASP content etc.
