In the ffmpeg source it appears to be in libavformat/mov.c and movenc.c, but 
the info actually included will vary with what's being stuffed into the 
container.

Sidestepping the question, there are decent write-ups at
https://atomicparsley.sourceforge.net/mpeg-4files.html
https://www.cimarronsystems.com/wp-content/uploads/2017/04/Elements-of-the-H.264-VideoAAC-Audio-MP4-Movie-v2_0.pdf

And while it's old, you could grab a copy of AtomicParsley and see what's in 
various test files.
