/* The following tables map FourCCs to codec names (as defined by libavcodec).
* However, this includes only names that are not defined by libavformat's
* RIFF tag tables, or which are mapped differently (for unknown reasons).
* These mappings were extracted from the codecs.conf file when it was removed,
* and these mappings have been maintained for years, meaning they are well
* tested and possibly make some files work. Or they could just be bugs.
*
* Note that demux_lavf does not use these tables, and always uses the native
* libavformat mappings.
*
* Note about internal mplayer FourCCs:
*
* These are made-up FourCCs which don't actually show up in files, but which
* were used by the original MPlayer to identify codecs. Since we don't quite
* know/care if there are still some uses of them left, they're still here.
