That is not a nice bug.

I'll have to think about the best way to handle this. I guess we will
have to revert the ABI breaking commit, identify the packages which are
broken (including ffmpeg itself like in this bug), add some Breaks for
them, and finally binNMU them. Alternatively we could force an ABI
transition and rebuild everything, but I'm not sure if I want to do
that (especially since we'll have to do another in a few months anyway).

Antoni, you should be able to fix your specific problem by upgrading all
the ffmpeg related packages (libav* etc) to 3.4.
