Guix,

The following patches add the VA-API back end for Intel GEN chips as well as libva-utils (which provides vainfo amongst many other things). I've tested them on my Ivy Bridge laptop and they work wonderfully.

However.

libva (I guess) searches for the back end in mesa's store output by default:

--8<---------------cut here---------------start------------->8---

vainfo libva info: VA-API version 1.4.1

libva info: va_getDriverName() returns 0

libva info: Trying to open /gnu/store/clhrbkacyrclwzkzdj2ql8y572whwjzi-mesa-19.1.1/lib/dri/i965_drv_video.so

libva info: va_openDriver() returns -1
vaInitialize failed with error code -1 (unknown libva error),exit
--8<---------------cut here---------------end--------------->8---

I don't know enough about libva or mesa to know how all this can be made to compose nicely.

I just tested and enjoyed VA-API acceleration by (icky icky boo boo) copying intel-vaapi-driver's library to the mesa store directory, so I need help in more ways than one.

Kind regards,

T G-R
