Yes, debian/rules has to do two things here: Strip the codecs out of 
the source tarball (in get-orig-source) and then strip the calling of 
these codecs out of the remaining code.

Nice instructions, but: If you set DEB_BUILD_OPTIONS on a separate 
command line, you should export them to the environment. This is why I 
suggested to set them on the same line as the calls to "fakeroot 
debian/rules" resp. "dpkg-buildpackage".

Regarding the problem with the package version remaining the same, you 
can add a new revision number by running e.g. "dch --nmu" or similar.

No, there isn't! Rebuilding the Debian packages to achieve extra 
codecs is completely unsupported. We introduced the "internalencoders" 
options just for convenience reasons.

Cheers,
Fabian
