Pineview + libva

Pineview + libva

[Steven Newbury]

I'm building a HD network media player device and thought VAAPI was supposed to be supported on Pineview, am I wrong?

To answer my own question somewhat, from the list here: 
http://en.wikipedia.org/wiki/Intel_GMA

It's clear the Pineview doesn't support hw VC-1 or AVC, but does support full MPEG2,
but I guess, given the utility of MPEG2 hw accel vs h.264 there isn't too much interest
in getting that working.

I'll just have to hope there's enough performance from the CPU to cope with 720p material...

I believe libva mostly supports gen4 and up. Pineview is supposed to
be gen3. Perhaps XVMC may still work for it though.
In general don't buy hardware unless you know the driver supports your
desired features. I should have listened to myself when I got a G45
and had the hope the h264 decoding support wouldn't take too long...

Cheers,

Sander
