Ahem, XBMC uses libavfilter. XBMC would like to have buffersink filter
merged into libav. We would also like all the other new changes in
libavfilter merged into libav as well (wherever possible). See [1] on
what it's like to support both libav and ffmpeg.

I already mentioned this in #libav-devel and was told Anton is working
on it. Not trolling here, just saying.

I have also been burned by debian-multimedia.org package conflicts, and at the same time I think that the debian-multimedia.org packages are a valuable resource.  I think it is a good idea to make debian-multimedia.org more distinct from Debian itself, and also, it is a good idea to try to get as much of the debian-multimedia.org packages into Debian as possible.  So I support the DPL's statement on that specific topic.
