Firefox was able to use VA-API on Intel (at least - I don’t have Radeon hardware to hand)
to accelerate H.264 decode.
Intel doesn't use Gallium (Mesa) for VA-API. You need a separate
driver package for it, which we currently don't ship and the version
being reviewed will not have these codecs enabled.
And we ship gstreamer1-vaapi which lets any GStreamer using
application (Totem, for example) use hardware acceleration.
Hmm, I forgot about that. FFmpeg doesn't have it because ffmpeg does
stupid things when the codec is available but doesn't work. GStreamer
is probably more intelligent about failing over.
