ui('Tutorials: Streaming with Icecast and IDJC', 'tutorials-icecast-nav')
</script>
<h4>Aims</h4>
<p>In this section I'm going to walk you through the procedure of setting up an Iceccast server
and then sending a live stream to it with IDJC. In addition I will demonstrate the connection of
a listener to show that everything really does work.</p>
<p>The advice below is for demonstration purposes only. Not covered are best practices of locking
down an Icecast server for serious use. For that and other non IDJC related matters there are the
<a href="http://icecast.imux.net/">Icecast forums</a> and the Icecast documentation itself.</p>
<h4>Setting up Icecast</h4>
<h5>Why local?</h5>
<p>Everything in this tutorial will be demonstrated on the same machine and while not as impressive as
sending a stream half way across your house, by making this tutorial single machine specific I can
not only leave multi-machine as an exercise to the reader but also not have to worry about anyone's
local network specifics or how many machines they have reasonable access to.</p>
<h5>Installing Icecast</h5>
<ul><li>
<p>Ubuntu</p>
<pre class="reduced">sudo apt-get install icecast2</pre>
</li><li>
<p>Debian</p>
<pre class="reduced">sudo -c "apt-get install icecast2"</pre>
</li></ul>
<h5>The configuration file</h5>
<p>Take a look in your /etc/<span style="color:red;" title="It could just be icecast. Ubuntu uses plain 
icecast for storing Icecast version 1 configuration files. IDJC does not support Icecast 1.">icecast2</span>/
directory and you should find a file called icecast.xml. This file is and will be referred to as the
Icecast server configuration file. In it are the settings for the various different Icecast options.
Here below are the typical contents.</p>
<pre class="big-code" title="icecast.xml"><icecast>

first connects, thereby significantly reducing the startup

it also significantly increases latency between the source

might want to disable this. --></span>

<p>What we should do now is copy and paste this file into a text editor or start editing a copy of your original
file. Hint: use your own file in preference to mine. Launch a text editor like gedit to do this.</p>
<p>Next, select Save As in the text editor's menu, choose the file name icecast.xml, and save it in your home directory.</p>
<h5>Attempting to run</h5>
<pre>$ icecast2 -c icecast.xml
FATAL: could not open error logging (/var/log/icecast2/error.log): No such file or directory
FATAL: could not open access logging (/var/log/icecast2/access.log): No such file or directory
FATAL: Could not start logging
</pre>
<p>Fix this by editing icecast.xml and change the logdir setting to /tmp which will solve the problem of
inadequate write permissions and try again. Leave Icecast running for the time being.</p>
<h4>Configuring IDJC</h4>
<p>Start the Jack sound server as follows.</p>
<pre>$ jackd -d dummy -r 44100</pre>
<p>This is done so that any media player, even one that does not support Jack Audio Connection Kit can be
used for playing the stream on this machine.</p>
<p>Run IDJC and click the Output button in the bottom left hand corner. Click Configuration so the
configuration section is visible.</p>
<p>Click Connection, then New.</p>
<p>For Server type you want Icecast 2 Master, for Hostname, localhost, port number should be 8000, mount point
can be what you like but choose /listen, login name needs to be source and the password will be the default
password, which is <span style="color:red;" title="Obviously a server exposed to the Internet should never 
be configured to use its default password">hackme</span>. Click Ok to add the server to the list.</p>
<p>Click Format. Select the Sample rate drop down box and choose 44100. Select MP3 and the top drop down box.
Choose 128, Quality 5, and Joint Stereo. </p>
<p>Click Individual Controls so the controls section is visible and click the button that says
localhost:8000/listen.</p>
<p>If the button stays in you have made the connection.</p>
<h4>Streaming some audio</h4>
<p>Click the down pointing arrow on the left media player and using the file selector add a track to the
playlist. Click play. Make sure the crossfader is set all the way to the left. Make sure Stream is on and DJ is off.
You should be able to see the Str Peak meter is active.</p>
<p>If you can't hear anything right now it's because DJ is off and/or you are running a dummy Jack soundcard,
which is what you want for the sake of this test.</p>
<h4>Join the stream as a listener</h4>
<pre>$ mplayer http://localhost:8000/listen</pre>
<p>After a brief moment audio should start to play and within thirty seconds the listener count in the main IDJC
window should have risen to 1. It's possible to add more listeners up to the maximum number currently
specified in the Icecast configuration file.</p>
