Icecast Streaming Server

  • Icecast Server
Icecast is an Internet audio broadcasting system based on Mpeg audio technology. It allows almost anyone to broadcast an audio stream to as many people as their bandwidth can support. It is developed and distributed under the GNU General Public License. Sources are available on

http://www.icecast.org/

The development platform for icecast is Linux 2.2, but it could also be successfully compiled and installed at OS X and Windows 95/98/NT.

Icecast receives streams from the encoder and servers to the recipients through TCP connections. Typical URL might look like http://laika.linux.tm:8000/laika.

  • Aliases / Relaying
Starting from version 1.3 Icecast offer dynamic relaying (aliasing) of streams. To relay a stream from another server, one has to add an alias for that server.

If one wants to relay the broadcast originating from one machine (for example stream laika.linux.tm:8000/laika), trough another icecast server, a line in the config file icecast.conf is needed: 

alias laika http://laika.linux.tm:8000/laika

What happens is that when a listener connects to relaying server and requests the /laika stream, then the icecast server connects as a client to laika.linux.tm, and then feeds the stream to the listener. All subsequent requests for /laika will use the same feed (i.e only one connect will be made to my machine). Icecast will automatically shut the link down when no one is listening. I.e no bandwidth will be wasted.
