I am using libva-mesa-driver 12.0.2. 

This is the error i get on Weston when i try to use vaapisink.

gst-play-1.0 --videosink vaapisink Videos/sintel_trailer-48 0p.mp4 Press 
'k' to see a list of keyboard shortcuts. Now playing 
/home/toliz/Videos/sintel_trailer-480p.mp4 libva info: VA-API version

Can you explain me how to perf the pipeline and how to pinpoint that it is a
driver issue?
