DESCRIPTION

32       MP4GetRtpPacketTransmitOffset  returns  the  transmit  offset of an RTP
33       packet. This offset may be set by some hinters to smooth out the packet
34       transmission  times  and reduce network burstiness. A transmitter would
35       need to apply this offset to the calculated transmission time based  on
36       the hint start time.
