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.
