I cannot make firefox 103 use hardware video acceleration on linux. When I set media.ffmpeg.vaapi.enabled to true it responds by setting gfx.blacklist.vaapi to 4 and gfx.blacklist.vaapi.failureid to FEATURE_FAILURE_VAAPI_TEST_FAILED and decodes video using CPU only. Nvidia GeForce GT 1030 - good for anything up to 8-bit H.265, Nvidia video drivers 470.129.06 (recommended), VDPAU and VAAPI are installed, chromium, vlc and mpv have no issues with hw accel on this system. Any ideas?
