The mp3 (or mpegaudio) decoder.

This question makes no sense to me, I suspect "nonfree" 
means something something completely different for you 
than for the FFmpeg developers.

The --enable-nonfree option of configure allows you 
to compile external libraries that are only available 
under a software license that is not compatible with 
the GPL. It is mostly needed for aac encoders like 
libfaac. It has no meaning for any internal parts 
of FFmpeg, FFmpeg does not contain any code that is 
not licensed under GPL or LGPL.
(The mp3 decoder is an internal part of FFmpeg.)
