During the get-orig-source mechanism we could add a file to the 
original tarball which contains the SVN revision as a string, e.g. 
svn-revision. We can then patch version.sh to look out for this file 
and parse its content, if it exists.

Since libswscale is an unversioned redirect from the ffmpeg SVN, I 
believe it is clear (i.e. unambigous) to reflect only the ffmpeg SVN 
revision. There is only one possible libswscale revision that can be 
assigned to one specific ffmpeg SVN revision.

Alright, we should start the work in experimental though. While we are 
at it, we can add an epoch to the Debian package to keep the ubuntu 
interdiff small and clean up some of the ancient replaces and 
conflicts fields. Maybe we should even switch from SVN to GIT as 
upstream did recently, although I don't have any experience with git yet.

I didn't know we were aiming at dropping libfaad? What's wrong with 
libfaad, apart from being GPLed?

You betcha! ;)
