Hello,
I'm new here and happy to have found this site!
I'm currently trying to code in java, I guess it doesn't matter what language I use, and I have a raw aac stream and want to wrap it into an mp4 type... How do I even begin to understand what it implies to do such task? Is it just a heather on the raw data or what? what does it imply to do such thing?
Thanks for the help!
Moto!

Sorry, can't really help you. I guess the basic idea (as I understand it) is to segment the raw bitstream into access units (those are the frames I guess, but I'm not sure) and add a header to each acess unit. The first access unit probably gets additional info about the MP4 file.
I guess you won't get around reading the MPEG-4 standard(s). Maybe the faac open source code can help you.
