[Mp4-tech] MPEG4 header

[mayank agarwal]

Hi all,
 I have the following doubts regarding MPEG-4 header
1.What is the standard header bit sequence of MPEG4
visual simple profile.
2.Is header for MPEG-4 video or H.263 is same or
different.
3.Is header in encoded bit stream of MPEG-4 same for
frame based encoding and packet based encoding.
4.What is the standard bit sequence of header of H263.
How to convert the frame based encoding in MPEG4 to
packet based encoding according to RTP rfc 3016 format
Is there any document or code sequence available which
tells how to do that.
        Many thanks in advance.
                                  Regards,
                                  Mayank
