I'm a bit confused now. Fabian noticed that Fedora's avidemux 2.5.3
package already did unbundle ffmpeg. Is this untrue? Or did I
misunderstand you two?

We would be happy to share the work and take your patches for using
the system libraries for the Debian package. Besides, have you by
chance already asked upstream to comment on your patches? If yes, what
was the response?

That's great to hear! Maybe we (i.e., in Debian) should, directly look
at packaging the 2.6 development branch.

Yes, that would probably be helpful for preparing the Debian package.
Do you use some VCS for your packaging work? In case you are
interested in our current packaging branch, it is at
http://anonscm.debian.org/gitweb/?p=pkg-multimedia/avidemux.git
