I think I have a doable solution: Let's have the avidemux source
package build depend on
libav-source, and have avidemux's build system apply its patches on
that source. This way
we have have the code duplication only in the binary code, but no
longer have to binNMU
avidemux in case changes happen in Libav.

Fabian, what do you think about this solution?
