The first and foremost question is, is there someone who wants
to work on merging the rockbox fixed point decoders back into ffmpeg?
if yes and this person or group wants a seperate ML for it then we
can create one. if not we dont need a new ML. If we do need one then
i have no strong oppinion about doing it like i suggested
or like you suggest.
Also any develper from rockbox who would want to maintain or improve these
fixed point decoders in ffmpeg-svn would of course get svn write access
This would be a huge advantage for all applications using libavcodec as
they would without any modifications benefit from the faster decoders
on fpu-less cpus.

There will always be a question for which you do not know the correct awnser.
