I can add that hardware video decoding in Firefox worked on this system a while ago, then it stopped working. Unfortunately, I don't know the exact moment when it broke, so I can't tell what changed.
I have tested nvidia-vaapi-driver 0.0.9 and 0.0.10, neither works. 0.0.9 seems to not support the 535.43.16 driver as vainfo
doesn't show any supported video formats.
set widget.dmabuf.force-enabled=true and try again?
Thanks, that did the trick.
Playing a video on Youtube in Firefox 119.0.1 does not use hardware-accelerated decoding. This is confirmed by
nvidia-smi
, as it shows Type "G" for thefirefox
process.Example video: https://www.youtube.com/watch?v=mvkXCvZ2ivI Video codec: VP9
Environment:
Firefox command line:
about:config:
Note: Although AV1 is enabled, I can confirm that it is not used for the video I'm playing (see the link above). This can be seen in "Stats for nerds" on Youtube.

:vainfo
:I tested the same video in
mpv
(withyt-dlp
), which is able to use NVDEC to accelerate decoding.mpv
is able to use hardware decoding on that video (again, the codec used was VP9).Operating System: Kubuntu 22.04 KDE Plasma Version: 5.24.7 KDE Frameworks Version: 5.92.0 Qt Version: 5.15.3 Kernel Version: 6.2.0-1016-lowlatency (64-bit) Graphics Platform: X11 Processors: 16 × 12th Gen Intel® Core™ i7-12700K Memory: 31.1 GiB of RAM Graphics Processor: NVIDIA GeForce RTX 2080 Ti/PCIe/SSE2 Nvidia driver: 535.43.16 (from here) Nvidia VAAPI driver: 0.0.11
