[Intel-gfx] acceleration works in Brave browser

[Grant]

Hardware acceleration doesn't seem to be working in Chrome but is
working in the Brave browser (which is based on Chrome) but only on
YouTube (with the h264ify browser extension).  I'm using one of these
which I believe is Bay Trail:

I've tried 6 or so streaming services but nothing accelerates besides
YouTube even though chrome://media-internals reports the h264 codec is
in use.  Does anyone know why this is happening?
