This is a giant patch that doesnt even begin to describe what it does.
So, whats it good for? We can already do transcoding of video from QSV
decoder to QSV encoder all in GPU memory without 600+ lines of new
code. Admittedly it currently has a few issues, but those could be
fixed, but why do we need 600 new lines of code?
