NAME
     multicat - Multicast equivalent of Netcat

SYNOPSIS
     multicat  [-i  <RT  priority>] [-t <ttl>] [-f] [-p <PCR PID>] [-s <chunks>]
     [-n <chunks>] [-k <start time>] [-d <duration>] [-a] [-r  <file  duration>]
     [-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 net-
     work streams (unicast and multicast, IPv4 and  IPv6),  files,  directories,
     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 and
     directories, the said clock is stored to an auxiliary file (example.aux ac-
     companies example.ts) while recording. Other inputs are considered  "live",
     and  the input clock is simply derived from the reception time of the pack-
     ets.

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

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

OPTIONS
     -a Append to existing destination file (risky)

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

     -f     Output packets as fast as possible

     -h     Show summary of options

     -i <RT priority>
	    Real time priority

     -k <time>
	    Start at the given position (in 27 MHz units, negative  =  from  the
	    end)

     -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

     -r <duration>
	    In	directory  mode,  rotate  file	after  this  duration  (default:
	    97200000000 ticks = 1 hour)

     -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

     -X     Pass-thought all packets to stdout
