NAME

       multicat - Multicast equivalent of Netcat

SYNOPSIS

       multicat  [-i  <RT  priority>] [-t <ttl>] [-p <PCR PID>] [-s <chunks>] [-n <chunks>] [-d <time>] [-a] [-S <SSRC IP>] [-u] [-U] [-m <payload
       size>] <input item> <output item>

DESCRIPTION

       Multicat is a 1 input/1 output application. Inputs and outputs can be network streams (unicast and multicast), files, character devices	or
       FIFOs. It is thought to be a multicast equivalent of the popular netcat tool.

       Multicat  tries	to  rebuild  the internal clock of the input stream; but it wants to remain agnostic of what is transported, so in case of
       files the said clock is stored to an auxiliary file (example.aux accompanies example.ts)  while	recording.  Other  inputs  are	considered
       "live", and the input clock is simply derived from the reception time of the packets.

ITEMS

       Item format <file path | device path | FIFO path | network host>

       Host format [<connect addr>[:<connect port>]][@[<bind addr][:<bind port>]]

OPTIONS

       -a Append to existing destination file (risky)

       -d <time>
	      Exit after a definite time (in 27 MHz units)

       -i <RT priority>
	      Real time priority

       -h     Show summary of options

       -m <payload size>
	      Size of the payload chunk, excluding optional RTP header (default 1316)

       -n <chunks>
	      Exit after playing N chunks of payload

       -p <PCR PID>
	      PCR PID

       -s <chunks>
	      Skip the first N chunks of payload

       -S <SSRC IP>
	      Overwrite or create RTP SSRC

       -t <ttl>
	      TTL of the packets send by multicat

       -u     Source has no RTP header

       -U     Destination has no RTP header
