Ouch. No, haven't tried yet... I was so happy that vaapi did work to 
some point using debian wheezy out-of-the-box, that I did not try to 
compile myself. I hope to find the courage to try that soon...

Thanks for checking.

And apologies for another bunch of stupid questions:

Is this a hardware limitation? Is it the same on ivybridge? vdpauinfo 
outputs such limits. Could something like this be added to vainfo, too?

That's nice.

Thanks again!
