Firefox HEVC playback with HW acceleration, does it actually works ?
Hello all, Recently Firefox 137 was announces with the addition of HEVC playback with hardware acceleration support for Linux. I am using Firefox 137 installed via DNF on Fedora 41, but if I try to play HEVC video for example from my Jellyfin, it will have to transcode, if I go try this test sample it straight up not play, so what's up with that ? Playing content with mpv will work just fine. Firefox also reports HEVC decoding as supported. Same result with both my desktop with AMD iGPU and dGPU, as well as my laptop with just Intel iGPU.
