Yes indeed I messed-up for a moment.

The opengl* family seems to be working nicely. However -hwdec=vaapi
does not seems to be working for me:

I am guessing VAProfileH264High is not compatible with VAProfileH264Main

Make sense, but it made the symptoms go away :)

What do you mean ? What's broken about fglrx and vaapi in debian ?
