I think the best place for information on .mp4 is
They have a opensource implementation of a .mp4 fileparser. .mp4 differ a
lot from .mpg, but is very similar to the .mov format (A couple of atoms
differ). If you can make use of mpeg4ip's library for parsing .mp4 files, I
suggest you use it. I thought I would lose all my hair writing a good parser
for a system (Unfortunaly I cant give you that source, but my knowledge I
If you have any questions about the format, just ask =)
Oh, btw.. I think they have samplefiles as well, if they don¹t, I have lots.
The next step on the MPEG4 path would then be to implement the AAC and CELP
