Good to hear that the mp4 reader is coming along. As far as audio is
concerned, have you looked into faad2 available at
http://www.audiocoding.com. If I am not mistaken, 3ivx and Winamp use
it for decoding aac audio on Windows and I believe Winamp also uses it
to encode aac audio into mp4 files. There is also an aac
implementation in the Helix(Real) source tree but I am uncertain if
their license is compatible witht he one used but Haiku but it might
be possible to make a binary only dist. of the decoder.

You can find any relevant information regarding Helix at

Ok I might have a look at the audiocoding one. I looked at it once before and I thought it needed licencing.


Real Programs don't use shared text.  Otherwise, how can they use
functions for scratch space after they are finished calling them?

This is from the top of the faad2 readme.... Looks like it's GPLed. Not sure how that impacts the media kit:
