-----------------------------------------+-----------------------
 When starting playback on Fedora 26 on VAAPI capable
 hardware, the vaapi libraries fail to initialize
 properly, and we fall back to software decode.

 Switching back to Xorg, rather than Wayland and vaapi
 works correctly again.

 Under Wayland:
 {{{
 libva info: VA-API version 0.40.0
 libva info: va_getDriverName() returns -1
 libva error: va_getDriverName() failed with unknown libva
 error,driver_name=(null)

 }}}

 Under Xorg:
