A proper implementation should need no or at least no more than
maybe 4 lines in MPlayer, ffmpeg.c or whichever other application.
It should be handled completely transparently by the decoder,
either with hardware-acceleration flags or (probably easier
for now and with less bike-shedding) as a separate codec,
like the way mp3 and mp3float exists currently.
Besides the naming conventions not matching, I don't think
a patch that not only needs each application using libavcodec
to be changed for no good reason at all but also does not even
make any of the code at all available via libavcodec is not
even remotely acceptable.
