I'm using a playback profile with filters, OSD fading and deinterlacing
disabled, avsync2 enabled and mythavtest for playback (on a 1920x1080 at 50
display)
With VAAPI video and audio looks OK (although with -v playback you can see
frames being dropped), intel_gpu_top shows 90-98%
With VAAPI2 only a few video frames are shown every few seconds,
intel_gpu_top shows low gpu utilization.
