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.
