DESCRIPTION

30       MP4SetRtpTimestampStart  sets  the RTP timestamp start of the specified
31       hint track. Typically this is a random value that is  chosen  when  the
32       first  RTP packet is constructed by the MP4 library. However the  value
33       can be set explicitly for the hint track and stored. Typically this  is
34       used if it is desired that timestamps start at zero.

36       See IETF RFC 1889 for details regarding RTP timestamps and RTCP.
