--- Description ---
See review D24062 for the patch.
Hardware video decoding how-to:
0. (optional, hybrid VP9 on Skylake) Build libva-intel-driver with HYBRID=on
then export LIBVA_DRIVER_NAME=i965
1. Start a Wayland compositor e.g., Sway
2. Enable native Wayland support: export MOZ_ENABLE_WAYLAND=1
3. Enable WebRender: export MOZ_WEBRENDER=1 or gfx.webrender.all=true in
about:config
4. Enable VAAPI: widget.wayland-dmabuf-vaapi.enabled=true in about:config
5. Disable bundled FFmpeg: media.ffvpx.enabled=false in about:config
6. Play a H.264 or VP9 video e.g., https://www.youtube.com/embed/hVvEISFw9w0
?. Diagnose via export MOZ_LOG=PlatformDecoderModule:5 (look for "VA-API"
string)
On X11 just run Firefox within a Wayland compositor nested on top of
xorg-server e.g.,
$ cat /tmp/sway.conf
exec firefox https://www.youtube.com/embed/hVvEISFw9w0
$ MOZ_LOG=PlatformDecoderModule:5 sway -c /tmp/sway.conf |& fgrep VA-API
