Let me tell my story...I have ffmpeg and mpv with the VAAPI patch active, and I use mpv constantly for videos (even with GLSL shaders and using Vulkan's video output). So far no problems on an old AMD RX 580. First, I was able to solve my problem with acceleration in Firefox using this about:config option media.ffmpeg.vaapi.enabled = true Once I enabled it, in about:support I saw h264 hardware decoding support (but not h265 and my card is capable). VP8 and VP9 support is something my old RX 580 doesn't have, so I can't test the 4k video you posted. > > I have not noticed taht playing youtube run on my CPU.

In any case, my best experience is with ffmpeg+mpv, in this case VAAPI works perfectly even with my custom mpv configuration which is quite demanding (several GLSL including one that simulates FSR, I have tested it with resolutions up to 2160p60 in h264 and h265, and no problems with acceleration). -- "Dios en su Cielo, todo bien en la Tierra" ***********************************************
