Comment (by jamal):

 Can you try using -vn in the command line?
 Something like
 {{{
 ffmpeg -i testfile.m4b -map_metadata 0:s:0 -vn -codec:a libmp3lame -q:a 4
 done.mp3
 }}}
 And see if it stops buffering all the audio in memory until conversion is
 completed (Which would fix the out-of-memory crash)
