ffmpeg can do lots of different conversion but faad just does aac. So
faad is small lightweight but can only convert files - it cannot handle
http.  LMS can strip AAC from simple http stream which is why LMS can
play AAC stream such as somafm but AFAICT LMS cannot strip AAC out of 
mp4 streams over http.

LMS rules deal with audio formats and not transport mechanism so
changing mp4 rules means ffmpeg will do all AAC/MP4 conversion and not
faad.  Main loss of functionality is seeking - as currently setup ffmpeg
rules cannot seek to a specific point in a file
