Here's an (incomplete?) list:
- It's horribly bloated. The libfaad2 directory in MPlayer, which is a
CVS snapshot taken from FAAD2 on 20040712 is 2.5M!
- It's slow. Audio decoding should never take 30% CPU (and more!) on a
500MHz class machine.
- The license is now GPL-incompatible since they added an extra
"advertising clause". This only applies to the latest CVS snapshots,
but it means that we have to fork or drop FAAD2 in the long run.

Now that would sure be most welcome.. Does anybody have specs?
