This sounds rather complicated to me.

Indeed, if we have to play with libavcodec files and build, why not just take a version of this
library, hack it to generate a libwineavcodec.so which contains all the typical codecs
we want to be supported in wine and finally generate an rpm which contain the shared lib + the headers.

This way if I want one day to break all the video (and soon audio) wrapper, noone will have
to update the lib. The update will be done from time to time when syncing with ffmpeg sources.
And finally, when the time comes when ffmpeg people provide and maintain a shared lib with a
stable API, we will have just to drop ours and take theirs. :-)

The problem is to find a place to host it and find a victim to do the package and maintain it. (You? :-))

Bye,
