Setup Icecast with PHP

Setting up multiple audio streams using Icecast in PHP requires a combination of server-side and client-side code. Below, I’ll provide a simple example of how you can set up a basic Icecast server with multiple streams and a PHP script to stream audio from the microphone using the Icecast source client, ices.

Step 1: Install Icecast

First, make sure you have Icecast installed on your server. You can follow the official Icecast documentation for installation: Icecast Installation

Step 2: Configure Icecast

Edit the Icecast configuration file (usually located at /etc/icecast2/icecast.xml on Linux systems) to include multiple mount points:

<!-- /etc/icecast2/icecast.xml -->
<icecast>
  <!-- Other Icecast configuration settings -->

  <mount>
    <mount-name>/stream1</mount-name>
    <username>source</username>
    <password>hackme</password>
    <max-listeners>10</max-listeners>
    <!-- Other mount-specific settings -->
  </mount>

  <mount>
    <mount-name>/stream2</mount-name>
    <username>source</username>
    <password>hackme</password>
    <max-listeners>10</max-listeners>
    <!-- Other mount-specific settings -->
  </mount>

  <!-- Add more mount points as needed -->

  <!-- Other Icecast configuration settings -->
</icecast>

Step 3: Install Ices

Ices is the source client for Icecast. Install it on your server:

sudo apt-get install ices2

Step 4: Create a PHP script to stream audio from the microphone

Create a PHP script (stream_mic.php) to execute the ices command and stream audio from the microphone:

<?php
// stream_mic.php

$stream1Command = "ices /path/to/ices-config-stream1.xml";
$stream2Command = "ices /path/to/ices-config-stream2.xml";

// Execute commands in the background
exec($stream1Command . " > /dev/null 2>&1 &");
exec($stream2Command . " > /dev/null 2>&1 &");

echo "Audio streams started.";
?>

Step 5: Create Ices Configuration Files

Create separate Ices configuration files (ices-config-stream1.xml and ices-config-stream2.xml) for each stream:

<!-- ices-config-stream1.xml -->
<ices>
  <background>1</background>
  <consolelog>0</consolelog>

  <stream>
    <metadata>
      <name>Stream 1</name>
      <genre>Various</genre>
      <description>First audio stream from the microphone</description>
    </metadata>
    <input>
      <module>oss</module>
      <device>/dev/dsp</device>
      <samplerate>44100</samplerate>
      <channels>2</channels>
      <type>mp3</type>
    </input>
    <instance>
      <hostname>localhost</hostname>
      <port>8000</port>
      <password>hackme</password>
      <mount>/stream1</mount>
    </instance>
  </stream>
</ices>

Create a similar configuration file for the second stream (ices-config-stream2.xml) with appropriate settings.

Step 6: Run the PHP script

Run the PHP script to start streaming audio from the microphone to multiple Icecast streams:

php stream_mic.php

Ensure that the Icecast server is running, and you should be able to listen to the streams at:

• http://your-server:8000/stream1
• http://your-server:8000/stream2

Adjust the configuration files and PHP script as needed based on your requirements and server setup.
