NAME

       poc-fec - send FEC MP3 streams

SYNOPSIS

       poc-fec [ -s address ] [ -p port ] [ -t ttl ] [ -q ] [ -k fec_k ] [ -n fec_n ] files...

DESCRIPTION

       poc-fec  is  a streaming server sending mp3 data using a custom FEC protocol. The streamed
       MP3 frames are first decomposed in autonomous data units (ADUs). These  ADUs  are  grouped
       into  ADU groups, which are encoded redundantly using a FEC method by Luigi Rizzo. A group
       of k ADUs is encoded as n data packets. Any k of these n data  packets  is  sufficient  to
       recover  the  original  k ADUs. It sends the files in the order given on the command-line.
       Use the filename - to stream from standard input. Normally, the FEC protocol  is  used  to
       stream to multicast groups.

OPTIONS

       -s address
              Specify the address to send to (default 224.0.1.23).

       -p port
              Specify the port to send to (default 1500).

       -t ttl Specify the TTL parameter to be set on outgoing parameters (default 1).

       -q     Don't output any information on standard error.

       -k fec_k
              Specify the number of ADUs that will be encoded as an ADU group (default 20).

       -n fec_n
              Specify  the number of packets that the ADU groups will be encoded to (default 25).
              This number must be greater than the fec_k parameter.

EXAMPLES

       poc-fec -s 224.0.1.24 -p 8989 -t 2 -k 16 -n 32 bla.mp3
              Send the file bla.mp3 using the RTP RFC fec protocol to the address  224.0.1.24  on
              port  8989,  and  set the TTL to 2. MP3 frames of bla.mp3 are converted to ADUs and
              grouped in ADU groups of 16 ADUs. These 16 ADUs are encoded  into  32  packets  and
              streamed. A client will have to receive at least 16 packets to recover the original
              ADUs.
