Thanks, Jan!

My Comet Lake is 0x9b41, so it looks like intel-media-driver should work
with it. That leads me to wonder how I can determine which VA driver is
actually in use. I'm guessing it might be "VDPAU driver: va_gl", but I am
unsure what that means other than that VA is there (which I also know from
video performance). I now have all three Intel VA drivers installed. and
added the patch to include Comet Lake cards into libva-intel-driver.
