Public bug reported: Firefox SNAP will play videos using hardware decode (e.g. VP9, H264) except for AV1 which does not work (as shown by intel_gpu_top). I have an 11 gen intel CPU/GPU which includes AV1 decode hardware. Firefox SNAP about:support media reports hardware decode for AV1, but it doesn't work. I have installed Firefox Flatpak and AV1 hardware video decode works on that.
