distmp3host - daemon for distributed mp3-encoding across multiple hosts on a network




distmp3host is daemon part of distmp3, a utility for distributed mp3-encoding across multiple hosts on a network.

The daemon binds port 4600 on localhost and waits for connections. The client connects to a remote host on port 4600 and a handshake occurs.

If the handshake goes well the daemon creates two named-pipes (fifos) for the mp3-encoding program to use. It also forks one child as reading or writing from/to the fifos is a blocking system call.

The daemon passes the recieved wav data to the output-fifo (which the mp3-encoding program reads its data from).

The daemon reads the encoded mp3-data from the input-fifo (the one the mp3-encoder write it's encoded mp3 to) and sends it back to the client who writes it down in a file.

Default values are used if none specified, and those defaults are read from /etc/distmp3/distmp3.conf


-p port
The port to listen on.
-s datasize
The datachunksize to use when sending data to the distmp3host server.
-d debug
If 1 then debugmessages will be printed on stdout, else suppressed.
-df debugfile
If defined debugmessages will be printed to file debugfile
-w wavfifo
The fifo used for writing the wavfile to so the encoder can read it.
-m mp3fifo
The fifo used by the encoder to write the mp3stream to.
-e program $wavfifo $mp3fifo
The program used for encoding the wavdata into mp3.

$wavfifo will be replaced with what was specified with -w

$mp3fifo will be replaced with what was specified with -m
