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.
