FFmpeg uses Git now. The SVN repository is outdated. You should switch
to the Git repository as the last SVN commit was in January 2011 (or
simply download a Git snapshot):

--disable-mmx was used for PowerPC I think. I don't think you need it
for the recent architecture. But IANAMacUser.
More importantly, if you want mp3 encoding support, you need to install
lame and build ffmpeg with --enable-libmp3lame.

Your command is telling ffmpeg that your output is a file named "mp3".
Once you recompile ffmpeg with --enable-libmp3lame the remove the
superfluous "mp3" from your command and it might work, and if not then
add "-acodec libmp3lame".
