Mmmh, so I guess I had the wrong version of i965-va-driver, now it's
happier:
saruman [mc]$ VA_INTEL_DEBUG=1 vainfo
libva info: VA-API version 0.38.0
libva info: va_getDriverName() returns 0

but mplayer still does not play 4K realtime with that driver either :(

Strangely vlc seems to play 4K realtime:
saruman [mc]$ vlc GOPR0076.MP4

libva info: Found init function __vaDriverInit_0_38

So I guess the driver is ok, and mplayer to blame?

Thanks,
Marc
