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
