The lavcac3enc filter depends on internal FFmpeg implementation details that are not part of the FFmpeg API. This means that even backwards-compatible FFmpeg changes can break it at any moment. The git version doesn't compile such filters by default (the MPlayer svn repo does, and occasionally breaks as a result). You can still enable those filters by using the --ffmpeg-source-dir=PATH_TO_FFMPEG_SOURCE_DIR option. For example if you have the build repo in /home/james321/src/mplayer-build then you can add either
in the mplayer_options file, depending on whether you have enabled FFmpeg-mt support or not. This should create an MPlayer binary that supports lavcac3enc. Note that it's disabled by default for a reason; if you encounter other problems later then it's worth testing whether removing this option helps.
