Disable hardware video decoding for VP9 only?

Is it possible to disable hardware decoding for VP9 exclusively. Watching a 4K video on YouTube results in anywhere from 10% to 50% of frames dropped, which is not a great experience. If I disable video decoding entirely I get 0% dropped frames, but with 20% cpu overhead, therefore I'd like to disable it for VP9, but keep it for H264.

There are two vp9 enabled prefs on the about:config page, you can leave the latter for WebRTC set to true.

  • media.mediasource.vp9.enabled = false
  • media.peerconnection.video.vp9_enabled = true
