Any info about Linux drivers & OpenCL support?

Will hardware acceleration work in Firefox? It may require installing FFmpeg.

1. Install FFmpeg
2. Install ~/.config/firefox.conf
3. Install the enhanced-h264ify extension
4. Go to about:config and set media.ffmpeg.vaapi.enabled to True
5. Restart Firefox

The Intel Arc Graphics support AV1. I’m not sure about VP9. So it may require installing the enhanced-h264ify extension to block VP8 and VP9.

[ ]  Block 60fps video
[ ]  Block h264
[x]  Block VP8
[x]  Block VP9
[ ]  Block AV1
[ ]  Disable Loudness Normalization

Will LIBVA_DRIVER_NAME be determined automatically or require setting in ~/.config/firefox.conf? Adjust LD_LIBRARY_PATH accordingly to where FFmpeg libs reside.

export FONTCONFIG_PATH=/usr/share/defaults/fonts
export LD_LIBRARY_PATH=/usr/local/lib
# export LIBVA_DRIVER_NAME=???

if [[ $XDG_SESSION_TYPE == wayland ]]
then
    export EGL_PLATFORM=wayland
    export MOZ_ENABLE_WAYLAND=1
else
    export MOZ_DISABLE_WAYLAND=1
    export MOZ_X11_EGL=1
fi

export MOZ_ACCELERATED=1
export MOZ_DISABLE_RDD_SANDBOX=1
export MOZ_USE_XINPUT2=1
export MOZ_WEBRENDER=1

Good luck and blessing Intel engineers with Arc Graphics. Hoping that all goes well.

I am not so sure if it’s on their priority list right now.

the sandbox is still broken?
i don’t have it disabled and my acceleration works just fine. i also have media.rdd-ffvpx.enabled set to true.

Thank you for sharing regarding Intel graphics (disabling not needed). Setting MOZ_DISABLE_RDD_SANDBOX=1 is required for the NVDEC back-end VA-API driver. It is mentioned in the README from nvidia-vaapi-driver.
