This is the demuxer library from the ffmpeg project. It supports most

Lucas told me yesterday that this affects ~80 other packages as well, is
that correct? Can we expect to see this patch in squeeze, or shall I
move the breaks as outlined above?
CC'ing the release list for input, since we are in freeze now.
