What distro?
Are you running wayland?
Tried xorg?

https://code.mythtv.org/trac/ticket/13104
https://bugzilla.redhat.com/show_bug.cgi?id=1491186
https://github.com/01org/libva/issues/79

Essentially with the latest wayland / vaapi / libva that's in f26,
vaapi fails to initialize when using X based connections to wayland.

Unfortunately making it work is going to require adding wayland support.

The workaround is to use xorg rather than wayland :(
