/etc/environment:

NVD_BACKEND=direct
MOZ_DISABLE_RDD_SANDBOX=1
LIBVA_DRIVER_NAME=nvidia

And firefox MOZ_DISABLE_RDD_SANDBOX=1 LIBVA_DRIVER_NAME=nvidia firefox running a 4K video runs on software decoding. Any idea what i am doing wrong?

EDIT: Using X11

Solved this by adding this to the /etc/environment file:

LIBVA_DEVICE=/dev/dri/card0 LIBVA_DISPLAY=drm

also added myself to the group vglusers which was the owner of /dev/dri/card0 (Dont know if this is needed)
