Missing avformat module

I realize this type of thing has been covered in other threads, however obviously my problem is different - and it is stubborn enough to where I just cannot figure out what is wrong.

I'm trying to run with the latest packages Debian Multimedia/testing. I can never get "melt -query producers" to show avformat, even though /usr/lib/mlt/libmltavformat.so exists and there are no broken links (ldd) with any executable or shared library that I can find.

ffmpeg, melt, kdenlive, etc. - all coming from the same repository (again, Debian Multimedia / testing).

I've tried removing melt, ffmpeg, kdenlive, libavformat52, etc. - then looking for leftover shared libraries, could find none, reinstalled, etc.

I'll get the basics out of the way first. Any hints or suggestions would be most appreciated!
