A Voice from the Other Side

The thread on debian-devel has mostly been a civil discussion. Yet I can't recall of a single valid argument that was raised there for keeping libav The only partial exception I recall "It's already in Stable. We have to keep it for as long as we support Stable anyway." which is somewhat valid, but may also be throwing good money after bad money (if libav is the worse choice of the two).

Oh: and that there's a single package (gstreamer-libav(?)) that only builds with libav and not with ffmpeg (while there are a number of other packages in the other direction).

Now, would you (or any other libav developer) kindly respond there? Or should Debian just replace libav with ffmpeg, given that no decent counter arguments were presented?
