No, though once in a while there tends to be one that works with one but
not the other, in both directions.
Primary candidates for removal are IMO demux_nuv.c (possibly with
corresponding decoder) and demux_mpc.c definitely with corresponding
decoder, because it does not work with ffmpeg decoder and when muxed
into AVI will create a format that (although I find it more sane) is
very different from what lavf creates and not playable with ffmpeg
decoder either.
