Title:
  [regression] MPV fails to use hardware acceleration (vaapi) on Intel
  graphics, starting in mpv 0.27 (bionic)

Status in mpv package in Ubuntu:
  Fix Committed

Bug description:
  MPV fails to use hardware acceleration (vaapi) on Intel graphics,
  starting in mpv 0.27 (bionic).

  It's appears the required /etc/mpv/mpv.conf is present, but the line
  "hwdec=auto" is failing to try vaapi. It bails when it finds Nvidia
  CUDA doesn't work, and just decides to use software instead.

  This is related to an issue that's come up before (bug 1728514 ?). The
  simple fix should be to use hwdec=vaapi instead. That will re-enable
  acceleration on Intel GPUs and also fix Nvidia GPUs failing to display
  video in some cases (they will get software playback instead of broken
  CUDA options).
