As noted elsewhere - I think you actually need to go into the video
display profile details and update them. You will need a combination
of vaapi (decoder) and opengl-hw (renderer).

If you are still getting that VAAPI error message then there is
something wrong. Are you running under Wayland? The only thing I can
think of is the "Decoder device for VAAPI hardware decoding' that is
under settings->video->playback->advanced playback settings. The code
will default to /dev/dri/renderD128
