Based on a recent report (https://discourse.ubuntu.com/t/problems-with-
intel-iris-xe-gpu-hardware-video-acceleration-in-22-04/34849/4), I think
Firefox is missing:

* Xwayland support: requires libva >= 2.17 in the gnome-42-2204 snap.
That's also missing from jammy-updates.

* Intel 13th gen support: The fix for bug 2004237 needs to go in the
gnome-42-2204 snap (patched iHD_drv_video.so).

Bug description:
  This is a Meta Bug for GPU accelerated video decoding on Ubuntu/Linux browsers.
  We will close this bug when both browsers will have Va-api decoding working OOTB without user interaction like in WinOS and MacOS

  August 2022 :

  * Ubuntu 22.04 : Launch firefox snap on Intel Tiger lake -> Check with
  intel_gpu_top that no codec are GPU decoded ( either VP9 , H264 or AV1
  )

     -> change media.ffmpeg.vaapi.enabled to true = VP9 and H264 decoding works
     -> AV1 hwdec does not work in Firefox or VLC , but does with MPV . We need to fix this as most youtube is AV1 now.

  * In july 2020, things are getting better :

  - Chromium :

  A patch is used on most distro packages. , more info here
  https://bugs.launchpad.net/ubuntu/+source/chromium-
  browser/+bug/1816497

  - Firefox :

  Firefox team has done a great job and now Va-api decoding in Wayland
  is possible and X11 is possible in nightly !

  Follow it here : https://bugzilla.mozilla.org/show_bug.cgi?id=1210727

  * In 2015 I opened this bug , no easy solution was available and
  battery drained when playing video in browser was crazy.
