Oh OK, I guess it's early days but cabac was one thing that seemed OK.

There are many issued on Tonga using vaapi - but then I suppose
gstreamer and ffmpeg are not really set up for it yet.

eg. worse first = gpu vm fault/lock with gstreamer but not ffmpeg.

to provoke do

gst-launch-1.0 videotestsrc ! video/x-raw, format=NV12, width=1920, 
height=1080, framerate=60/1 ! vaapih264enc | fakesink

then flip away/back to another desktop soon will lock.

Maybe I am too early eg. other patches needed? or does what you say
above mean that vaapienc shouldn't even be enabled for older chips?
