Most of these demuxers and decoders are provided in better form by libav, while the mplayer builtin ones are essentially unmaintained. The only legimitate use case for not using the libav ones was working around libav bugs or bugs related to the way mplayer uses libav. Instead of trying to keep dead code alive, development effort should go into improving libav or the mplayer libav glue code. Note that the libav demuxer have been preferred over the mplayer builtin ones for a while in mplayer2. There were some exceptions: playing DVDs with dvdnav or playing network sources. (That's because some stream modules and network.c requested explicit file formats, such as DEMUXER_TYPE_MPEG_PS, which mapped to builtin demuxers.) With this commit, they are switched to use libav. One caveat is that the requested format is not passed to libavformat, instead we rely on the auto probing to select the correct libav demuxer (see code in demux_open_stream()).
