RTPPLAY(1)

NAME
rtpplay - play back RTP sessions recorded by rtpdump

SYNOPSIS
rtpplay [-hTv] [-b time] [-e time] [-f infile] [-p profile] [-s port] address/port[/ttl]

DESCRIPTION
rtpplay reads RTP session data recorded by “rtpdump -F dump”, from standard input and resends the traffic to the given address/port, optionally with a time-to-live value of ttl.

The options are as follows:

-b time
    Skip the first time seconds of input.

-e time
    Only use the first time seconds of input.

-f infile
    Read input from the given infile instead of from standard input.

-h  Print a short usage summary and exit.

-p profile
    Use the specified profile of payload type to frequency mapping. By default, rtpplay uses the frequency profile specified in RFC 1890. For example, A-law PCM audio will be a single channel with a sample rate of 8 kHz. The profile file consists of lines containing two numeric values: the numeric payload type and the sample rate. This is silently ignored if -T is used.

-s port
    Send packets from the specified port. By default, packets are sent from a random port.

-T  Time the outgoing RTP packets according to the original arrival time. By default, the RTP timestamps are used for timing instead. This smooths jitter and restores the packet sequence. RTCP packets are always sent with their original arrival timing, which may change the relative order of RTP and RTCP packets.

-v  Print the packets to standard output as they are sent out. By default, rtpplay operates silently.
