| .SH "DESCRIPTION" |
| .LP |
| \fBMP4GetRtpPacketTransmitOffset\fR 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. |
