Hi,

Steps followed:

  1. Edit /etc/default/grub to set GRUB_CMDLINE_LINUX="nvidia-drm.modeset=1" and run grub-update then restart.
  2. Clone, configure, and compile, allowing sudo access when prompted.
  3. Observe the nvidia_drv_video.so file has been successfully placed in the /usr/lib/x86_64-linux-gnu/dri directory.
  4. Observe the output of ffmpeg -hwaccels to be:
Hardware acceleration methods:
vdpau
cuda
vaapi
qsv
drm
opencl
  1. Edit /etc/environment to have:
MOZ_DISABLE_RDD_SANDBOX=1
LIBVA_DRIVER_NAME=nvidia
NVD_BACKEND=direct
  1. Restart session, observe those env variables are set.
  2. Go to about:config in firefox, and set the following variables:
media.ffmpeg.vaapi.enabled: TRUE
media.rdd-ffmpeg.enabled: already TRUE
gfx.x11-egl.force-enabled: TRUE
widget.dmabuf.force-enabled: TRUE
  1. Restart whole PC just to be sure

Observation: It doesn't use the GPU. Without even looking at nvidia-smi I'm getting 75+% CPU usage on any given YouTube video, but well, nvidia-smi does not report a Firefox process.

The output of ./test.sh: https://gist.github.com/C-Lunn/2f3b1f62b956e3100b5a0bb5f5b44a2a
mpv version 0.38
about: support: https://gist.github.com/C-Lunn/e1711ca8daad9631f46b21afc158e7b7

Any ideas? Thanks!

Are you by chance on a laptop? The gpu driver strings in your about:support indicate that you have your integrated gpu active. The nvidia card isn't active so that is why you don't see hardware decoding. You can post the output of vainfo here but it will likely tell you that you don't have your nvidia card active, but rather your integrated gpu active instead.

I was on a desktop with a Ryzen 3600X which I don't believe even has an iGPU. Life circumstances have meant I'm currently without that particular setup. I'll close it for now, but if I get in a similar situation at some point in the future I'll re-open. Cheers.

Since you're on ubuntu it may be that you're using the snap version of FF.. (it think it doesn't work with the snap version) and wayland.. it doesn't work well on wayland either but at least it should show up in nvidia-smi
