I'm proposing to demote ffmpeg (and all of it's source packages!)
and packages containing/rdepending ffmpeg to multiverse.
The packages rdepending or containing ffmpeg are gem, gnusound,, motion, opencv, smilutil gst-ffmpeg, and vlc and must be
moved also to multiverse.

In the case of vlc it currently uses a bundled ffmpeg version as
libpostproc-dev is currently already in multiverse and vlc can't build-
depend on it because of that. Demoting it to multiverse will solve this
obviously ;)

This is for the following reason:
We currently use the ffmpeg from Debian but this is somewhat stripped
from "funny" formats (AAC for example, libfaad2 is in multiverse). When
ffmpeg is in multiverse we could use Marillat's version [1] of ffmpeg
which supports these formats. In fact even our version contains support
for some suspect formats (mpeg video encoding as an example).

Using Marillat's version would give us also another advantage (which
could be added to our current package too obviously):

Our current ffmpeg package ships only -dev packages for libavcodec
and libpostproc. These contain the static .a archives and no package
with shared .so libraries is available from our ffmpeg package. This
yields to the following problem: when updating ffmpeg all packages using
it need to be recompiled to use the advantages of the updated ffmpeg and
(more important) _every_ binary which links against libavcodec gets 2-3
mb bigger! for example for transcode this makes a real difference as it
contains many binaries linking against libavcodec. The compressed size
of the binary is ~14 MB instead of ~2 MB, the installed size is ~40 MB
instead of ~5 MB. Using Marillat's version also helps in this case.
Shipping only static libraries is also generally discouraged [2]

Do you have any comments on this or can we do it right now?

Thanks and Bye
