Specifies the hint track to which the operation applies.
packetIndex
Specifies the packet to which the operation applies.

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