Cédric Schieli submitted a patch that fixes VAAPI on Myth... See here:
 "This was definitely a Myth issue. A simple fix has been submited
(#12140). My Baytrail FE is now rock solid while hardware decoding MPEG2
and H.264 media (50% cpu usage instead of 90% before)."

I can confirm that the Patch does stop the segfaults... However I like the
De-Interlacing MUCH better in OpenGL High Quality than VAAPI.
