It can be done, but not directly using MPlayer or MEncoder. The simplest
(universally reliable) way is a two-step process:

1. Dump the audio from the stream into a WAV file:
mplayer stream.dump -vo null -vc dummy -ao pcm:fast:file=filename.wav

2. Transcode the WAV file into an MP3 file using an external tool, such
as LAME:
lame <your preferred MP3 encoding options> filename.wav filename.mp3


Alternately, if you'd rather not use multiple tools for a single task,
you can try FFmpeg:

ffmpeg -i stream.dump <your preferred MP3 encoding options> filename.mp3

This will not necessarily be capable of handling all files which MPlayer
can play, but it should be able to deal with most types of file.
