The first thing would be to get working vainfo. What kind of GPU does Amazon
provide? VAAPI works well on Intel GPUs and some other GPU using the gallium

vainfo should work without an X server running, just it warns about it.

If vainfo doesn't work, which is the most basic libva tool, gstreamer-vaapi
won't work either.
