[3gpp] Transcoding mp4a to mp3

Hello,


I would like to transcode some mp4a track from a 3gpp file to mp3.
But I would like to do it in real time : extracting an Acess Unit from the 3gpp file and give it to the transcoder, and so on until the end of the track.

I already have the tools to extract the headers (ftyp and moov boxes) and the AUs from the mdat box.

I don't know if such a library exists ... I hope yes !


Do you have an idea ?
Thanks in advance.


Cheers.
