Firefly has two ways of transcoding music.

There are two different sample transcode scripts in the /contrib directory. One is called mt-daapd-ssc.sh, and the other mt-daapd-ssc.pl.
The mt-daapd-ssc.sh script transcodes the following formats: ogg and flac. It isn’t much, but the advantage of this script is that it is easily adaptable to other more exotic formats.
The other transcode script, mt-daapd-ssc.pl, is more featureful, and transcodes just about everything: flac, aac, ogg, shn, au, apple lossless, etc. It (of course) requires perl, mplayer, ffmpeg, and alac-decoder depending on what types of media you are trying to transcode. This one makes more sense if you have a machine that can run it. It’s not as easily hackable as the .sh one.
It appears that the two builds have been set to use different transcoding methods
