NAME

       darkice.cfg - configuration file for darkice

DESCRIPTION

The configuration file consists of sections, with key = value pairs separated with spaces
and/or tabs inside each secion:

[section1]
# this is a whole line comment
key = value
an ugly key name = long value # this end is a comment too

[section2]
# this is a whole line comment in section 2
key = value
an ugly key name = long value # this end is a comment too

A proper DarkIce configuration file contains the following sections:
[general]
[input]
[icecast-0] ... [icecast-7]
[icecast2-0] ... [icecast2-7]
[shoutcast-0] ... [shoutcast-7]
[file-0] ... [file-7]

The order of the sections is not important. Sections [general] and [input] are required,
and at least one of [icecast-x], [icecast2-x], [shoutcast-x] or [file-x] is needed.

In particular, the following sections and values are recognized:

[general]

This section describes general operational parameters (required).

Required values:

duration
Time for DarkIce to run, in seconds. If 0, run forever.

bufferSecs
Data read from the sound card is buffered before sent to the encoder. Each buffer
will be able to hold this many seconds of samples.

Optional values:

reconnect
Try to reconnect to the server(s) if the connection is broken during streaming,
"yes" or "no". (optional parameter, defaults to "yes")

realtime
Use POSIX realtime scheduling, "yes" or "no". (optional parameter, defaults to
"yes")

rtprio Scheduling priority for the realtime threads. (optional parameter, defaults to 4)

[input]

This section describes the input (required).

Required values:

device Specify the device to record from, which can be an OSS DSP device, an ALSA source,
PulseAudio source or you can use Jack audio. - OSS DSP audio device to record from
(e.g. /dev/dsp) - ALSA DSP device name (e.g. hwplug:0,0) - for PulseAudio use
"pulseaudio" - the string 'jack', to have an unconnected Jack port, or
'jack_auto' to automatically make Jack connect to the first source.

sampleRate
The sample rate to record with, samples per second (e.g. 44100 for 44.1kHz CD-
quality audio, 22050 for 22kHz or 11025 for 11kHz)

A sample configuration file follows. This file makes DarkIce stream for 1 minute (60
seconds) from the audio device /dev/dsp at 22.05kHz, 16 bit stereo. It will build up a
connection to the IceCast server yp.yourserver.com on port 8000 with the password
"hackme". The stream will be encoded to 96 kb/s mp3 with quality 0.8, and will be
reachable at http://yp.yourserver.com:8000/live96 to mp3 players. The encoding session
will be stored by IceCast in the file /tmp/server-dump.mp3 on the server side, and also by
DarkIce in the file /tmp/encoder-dump.mp3 on the encoder side.

[general]

The following sample configuration file simply encodes the 16 bit stereo 44.1 kHz sound
card input into Ogg Vorbis at average bit rate 96 kb/s for 60 seconds, and saves it in the
local file at /tmp/save.ogg.

[general]
duration = 60

fileName = /tmp/save.ogg

A bit more complicated sample follows. This one makes DarkIce stream for 1 hour (3600
seconds) from the audio device /dev/dsp at 44.1kHz, 16 bit stereo.

It will build up a connection to an IceCast server yp.your-ice-server.com on port 8000
with the password "ice-hackme". The sound for this stream will be cut at 10500 Hz from
above. The stream will be encoded to average bit rate 96 kb/s mp3 and resampled to
22.05kHz and 1 channel (mono). The stream will be reachable at http://yp.your-ice-
server.com:8000/live96 to mp3 players. The encoding session will be stored by IceCast in
the file /tmp/live96.mp3 on the server side.

It will also connect to a ShoutCast server at yp.your-shout-server.com on port 8001 with
the password "shout-hackme" This stream will be encoded to constant bit rate 128 kb/s mp3
with quality 0.8, and will be reachable at http://yp.your-shout-server.com:8000 to mp3
players.
