RTPSEND(1)		     General Commands Manual		      RTPSEND(1)

NAME
     rtpsend -- generate RTP packets from textual description

SYNOPSIS
     rtpsend [-ahlv] [-f infile] [-s port] address/port[/ttl]

DESCRIPTION
     rtpsend  sends  a	stream of RTP and RTCP packets with configurable parame-
     ters.  The packets are sent to the given address/port,  optionally  with  a
     time-to-live  value  of  ttl.  This is intended to test the RTP features of
     the receiving end.

     By default, rtpsend reads the packets from standard input.  The RTP or RTCP
     headers are expected in a format written by rtpdump(1) -F ascii.

     Within the input, each entry starts with a time value, in seconds, relative
     to the beginning.	The time value must appear at the beginning of	a  line,
     without  white space.  Within an RTP or RTCP packet description, parameters
     may appear in any order, without white space around the equal sign.   Lines
     are  continued  with  initial  white space on the next line.  Comment lines
     start with `#'.  Strings are enclosed in quotation marks.	RTP and RTCP en-
     tries look like this:

     <time> RTP
	v=<version>
	p=<padding>
	x=<extension>
	m=<marker>
	pt=<payload type>
	ts=<time stamp>
	seq=<sequence number>
	ssrc=<SSRC>
	cc=<CSRC count>
	csrc=<CSRC>
	data=<hex payload>
	ext_type=<type of extension>
	ext_len=<length of extension header>
	ext_data=<hex extension data>
	len=<packet size in bytes(including header)>

     <time> RTCP (SDES v=<version>
		   (src=<source> cname="..." name="...")
		   (src=<source> ...)
		 )
		 (SR v=<version>
		   ssrc=<SSRC of data source>
		   p=<padding>
		   count=<number of sources>
		   len=<length>
		   ntp=<NTP timestamp>
		   psent=<packet sent>
		   osent=<octets sent>
		     (ssrc=<SSRC of source>
		      fraction=<loss fraction>
		      lost=<number lost>
		      last_seq=<last sequence number>
		      jit=<jitter>
		      lsr=<last SR received>
		      dlsr=<delay since last SR>
		     )
		 )

     The options are as follows:

     -a      Include a router alert IP option in RTCP packets.	This is used  by
	     the YESSIR resource reservation protoccol.

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

     -h      Display a short usage summary and exit.

     -l      Send the same sequence of packets again and again.  This only works
	     if  the  input  is read from a regular file instead of the standard
	     input.  See the -f option.

     -s port
	     Send the packets from the given port.  By default, rtpsend  chooses
	     a random port.
