This reverts commit689a25003f, with some adjustments to code that was added after that commit. I just messed up big time. We don't need this, and in fact the commit confused straight and premultiplied alpha at one point (just a simple inverted condition due to an oversight), which is why it looked like it was working. In commit2827295I wrote: Also, libva can't decide whether it accepts straight or premultiplied alpha for OSD sub-pictures [...] That was just me messing up and being severely confused by my own bugs. VA API uses premultiplied alpha, which by the way is nice and thoughtful of the VA API devs. Well, this was stupid. But in the end, I'm glad that I could actually reduce codesize by a good amount again.
