Thanks for the testing.

As intel-vaapi doesn't support GM965, IMO it makes sense that the above
error is returned on GM965/GL960.

AFAIK, GM965 has no support of libva/intel-vaapi. (The previous version
doesn't support it).

If the HW accelerated decoding/encoding is expected, you can use the
system on the Sandybridge or later. (The Ivy bridge is OK).

Thanks.
