Ok, that README.Debian file is quite old. The removal of such codecs is
not documented, apart from the changelog. I'll ask the maintainer.

Moreover I realized that marillat packages built from ffmpeg have
different names from official ones. Therefore they do not get replaced.

Video support can be enable by self-recompiling ffmpeg.
It can be done by following this procedure:

1. create the orig tarball according to
http://svn.debian.org/wsvn/pkg-multimedia/unstable/ffmpeg/README?op=file

2. Apply
http://ftp.debian.org/debian/pool/main/f/ffmpeg-free/ffmpeg-free_0.cvs20070307-6.diff.gz


3. Replace "ffmpeg-free" with "ffmpeg" inside debian/changelog and
debian/control (ehm, the right way would be adding a new entry in the
changelog)

4. Build the package (e.g. with dpkg-buildpackage)

Then you can install the new package and get video support in wengophone
(no recompilation of wengophone needed).

Leaving the bug open until proper documentation is done.
