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
