MP4 container format specification, Trying to write a low memory parser Options

[saratoga]

I've been working on making an mp4 parser for AAC files more memory efficient for targets with very little RAM. Unfortunately, just looking at source code for various parsers its somewhat difficult for me to see how the container actually works.

I've tried google but have found surprisingly little in the way of a detailed specification. Could someone recommend one to me?

That looks good, and apparently its very close to how mp4 works.

I'm still not really understanding how one walks through a chunk full of samples though. Is there header or similar on each chunk or sample that tells you about it, or do you have to parse that from the "sample table atom"?
