"# vainfo

libva info: va_getDriverName() returns 0

I had this problem on mythbuntu. Turns out I only installed the vainfo
package. You also need to install the i965 driver to go along with it.

I do not know the package name for that in CentOS. For Ubuntu
derivatives, these are the two packages to make vaapi work: vainfo
i965-va-driver
