We do not disagree at all on this point. I'm not saying that we should just upload ffmpeg as is, obviously it would be stupid to upload ffmpeg if it broke things. But we should welcome anyone who wants to do the work to make it possible to install libav and ffmpeg at the same time, or any other reasonable solution. And since this is a very political issue, we do need to speak carefully and clearly. That's why I object to the statement "Uploading ffmpeg would be a bad idea". It is very broad, and wrong from some legitimate Debian-specific points of view. > Furthermore, currently libav and ffmpeg share the same library name space > without being binary compatible - they are just not drop-in replacements for > each other.

I don't! I'm specifically interested in the ffmpeg command line util, I don't really need all the libraries. That wouldn't be hard to package. As for libraries, how about putting the ffmpeg versions into /usr/include/ffmpeg and /usr/lib/ffmpeg? Then if someone wants to build against them, they can add -I/usr/include/ffmpeg and -L/usr/lib/ffmpeg. For most projects that use the libav* libraries, there probably wouldn't be any difference between using the ffmpeg or libav versions, so it would be silly to make all packages for both. And of course, I'm not telling anyone that they should do the work here. I am saying we should welcome anyone who wants to do it.
