I can confirm that this doesn't work out of the box. When running the firefox snap with MOZ_LOG="PlatformDecoderModule:5", I can see that libva tries to load drivers from $SNAP/gnome- platform/usr/lib/x86_64-linux-gnu/dri/, where it can't find any such driver. This is bug #1947180, for which I've proposed a fix in snapcraft.
Once that is fixed, the next step is to ship said VA-API drivers, either in the firefox snap itself, or in the platform snap (gnome-3-38-2004). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1947115 Title: VAAPI / HW-acceleration not working Snap-packaged Firefox To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/1947115/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
