[FFmpeg-user] mp4 interleaving

I’d like to use mp4box for swapping the audio in some mp4 files, generated 
earlier with ffmpeg (h.264+aac). 

I am however not sure, whether the resulting container will be interleaved in a 
suitable way for, say, offline playback on a computer or a set-top box. The same 
interleaving structure would be fine, as ffmpeg did originally, but I don’t have 
a clue, how ffmpeg does it by default. What I'm most afraid is seeking problems 
and audio sync problems. 

So I wonder how ffmpeg interleaves an mp4 output ? (chunk size, whatever..)

Thanks in advance, Peter
