How to fix this VA-API error?

[Ralf Mardorf]

I'm seeing this on Arch Linux, too.

[rocketmouse at archlinux ~]$ vainfo 
libva error: /usr/lib/dri/iHD_drv_video.so init failed

Without doing any research my guess is, that it could be related to the
issue, that the intel driver isn't supported since years.
