AV1 Hardware Acceleration stopped working
AV1 Hardware Acceleration stopped working. In about:support->Media->Codec Support Information Firefox states that Harware Decode AV1 is supported but it uses only Software Decoding. AV1 worked perfeclty before in Firefox, is still working in other browsers and apps in my system.

Sorry I forgot to mention that h264/AVC and VP9 are working perfectly only the AV1 has this problem. Monitoring my GPU usage through intel_gpu_top.
I made some progress and I found out that the problem exist only on snap version of Firefox. I have also installed the flatpak version of Firefox and the AV1 HW acceleration decoding is working out of the box. So maybe the problem is that Firefox snap using outdated Mesa/VAAPI runtime and somehow is blocking the AV1 RDD inside snap sandbox?
