pob-3119 - receive RTP RFC 3119 MP3 streams
SYNOPSIS
pob-3119 [ -s address ] [ -p port ] [ -b size ] [ -q ]
DESCRIPTION
pob-3119 receives a RTP MP3 Stream using the protocol described in RFC 3119. The incoming stream is buffered and written to standard out in
order to be fed into a MP3 decoder.
OPTIONS -s address
Specify the address to listen to (default 224.0.1.23). If the address is a multicast address, group membership is requested automat-
ically.
-p port
Specify the port to listen to.
-b size
Specify the maximal number of packet that are hold in the ring buffer (default 128).
-q Don't output any information on standard error.
EXAMPLES
pob-3119 -s 224.0.1.24 -p 8989 | mpg123 -
Receive the MP3 RTP stream sent to 224.0.1.24 on port 8989 and feed it into the MP3 decoder mpg123.

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 param-
eter.
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.
