Looks like your last step is the easiest to do so perhaps I will try and 
get lucky and start there but...  having looked over the entire file, 
where are you suggesting the change?

By adding a line in this?

         $ffmpeg_pid = open(DATA,
             "$ffmpeg -y -i ".shell_escape($filename)
             .' -s '.shell_escape("${width}x$height")
             .' -r 24 -f flv -ac 2 -ar 11025'
             .' -ab '.shell_escape("${abitrate}k")
             .' -b '.shell_escape("${vbitrate}k")
             .' /dev/stdout 2>/dev/null |'
             );


Like this:

         $ffmpeg_pid = open(DATA,
             "$ffmpeg -y -i ".shell_escape($filename)
             .' -s '.shell_escape("${width}x$height")
             .' -r 24 -f flv -ac 2 -ar 11025'
             .' -acodec mp3
             .' -ab '.shell_escape("${abitrate}k")
             .' -b '.shell_escape("${vbitrate}k")
             .' /dev/stdout 2>/dev/null |'
             );

???

Please excuse me if I have the wrong place.
