NAME¶

pob-fec - receive FEC MP3 streams

SYNOPSIS¶

pob-fec [ -s address ] [ -p port ] [ -b size ] [ -q ]

DESCRIPTION¶

pob-fec receives a FEC MP3 stream using a custom 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. For example, a group if 8 ADUs can be encoded into 16 packets. Any 8 received packets of these 16 packets is sufficient to recover the original 8 ADUs. The incoming MP3 stream is decoded, buffered and written to stdout.

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 automatically.

-p port

Specify the port to listen to.

-b size

Specify the number of ADU groups that are hold in the buffer (default 16).

-q

Don't output any information on standard error.

EXAMPLES¶

pob-fec -s 224.0.1.24 -p 8989 | mpg123 -

Receive the MP3 FEC stream sent to 224.0.1.24 on port 8989 and feed it into the MP3 decoder mpg123.
