This one also uses Mplayer to convert the AC3 to WAV, then we go about the usual and convert to MP3 to WAV. I believe this still grabs FFmpeg for the codecs to transcode. I've added a line to convert AC3 5.1 to 2 channel stereo. Im not sure if it is needed, but I think AC3 is usually in 5.1 or 7.1, I may be wrong. If it is incorrect just remove "-channels 5 -af pan=2:'1:0':'0:1':'0.7:0':'0:0.7':'0.5:0.5'".
