I think the patches by Mark Thompson have a better chance of getting
in. However he isn't really interested in h264 encoding (he wrote on
IRC that the encoder provides the bare minimum, or so). Would you be
potentially interested in porting over your patch to the vaapi
infrastructure he is going to add, once his patches are in?
