[Libva] test/decode sample shows blank window

[Paul A. Steckler]

Yes, I mean the mpeg2vldemo program.

In fact, I had the master branch checked out from
github.com/gbeauchesne/libva.git, which
appears to differ from the "official" repository.

I checked out the repo at anongit.freedesktop.org/git/libva.When I run
mpeg2vldemo with that
code, it reports the VA API version as 0.37.0.

And I get the same behavior as with the other code. But, yes, when
kill the cinnamon window
manager in Linux Mint, I see the image of what appears to be a baby!

What causes this behavior?
