Glad to hear that you've got vaapi working. Did you check that vdpau
did not regress ?
I'm wondering if it's going to be better if you gradually re-factor
the existing code. The current "1. add 'new' implementation (incl.
variables we don't want/need until halfway through), 2. remove 'old'
implementation" approach does not seem too appealing imho.
Others might disagree with my suggestion, though :)
