I have struggled for a few days but still can't find the way. Anybody could help me out? Is there any references you can tell me? Thanks a lot.

Abstract 
ISO/IEC 14496-14:2003 specifies the MP4 file format as derived from
ISO/IEC 14496-12 and ISO/IEC 15444-12, the ISO base media file format.
It revises and completely replaces Clause 13 of ISO/IEC 14496-1, in
which the file format was previously specified.
The MP4 file format defines the storage of MPEG-4 content in files. It
is a flexible format, permitting a wide variety of usages, such as
editing, display, interchange and streaming.
