I had a quick look at the source code and found that calls to these
libraries ar made in src/vamps/k9ffmpeg.cpp like this one:
FormatHandle=dlopen("libavformat.so",RTLD_LAZY);
So in order to avoid the error, one should install the four involved
lib*-dev packages (actually, libavformat-dev and libswscale-dev will bring
in the two others).
I suspect this is probably not following the standard debian practices,
in which case, this bug shoud be reported upstream. Let me know what route
should be followed.
