ICEcast, Stream and Track Names, Configuration File

30 Section 3

SHOUTcast Radio DNAS application.

UNIX, LINUX, FreeBSD and MAC OSX:

1.Download the SHOUTcast DNAS application version appropriate to your system by proceeding to this link.

2.Unzip the distribution and un-tar the archive.

3.Use a text editor to configure the sc_serv.conf file

4.Note that the user you run the server as requires read access to the config file, and write access for the files you define for file storage and log storage.

Configuration File

Like Steamcast, the SHOUTcast Radio Server configuration file contains several options that can be changed. See the SHOUTcast website for details.

ICEcast

Icecast is a free streaming media project maintained by the Xiph.org Foundation. It also refers specifically to the server program which is part of the project. The main website for information and download is: http://www.icecast.org. Kerry Cox offers an excellent online “book” devoted to Icecast at: http://www.gnuware.com/icecast/.

Icecast was created by Jack Moffitt and Barath Raghavan to provide an open source audio streaming server that anyone could modify, use, and tinker with.Version 2 was started in 2001, a ground-up rewrite aimed at multi-format support and scalability.

The Icecast server is capable of streaming MP3 and AAC over the SHOUTcast protocol. (AAC is only supported in version 2.2.0 and newer.) It runs on both Linux and Windows.

Icecast is generally regarded as being the most sophisticated and capable of the streaming servers, especially for users who want to use Linux and are comfortable with command-line interfaces. It supports detailed reporting of audience statistics. For simple in-house distri- bution applications, Icecast might be over-the-top. But for serious public Internet radio station-like streaming, this might be just what you need.

As of the writing of this manual, we have not yet tested Icecast in our lab, but there is no reason why it shouldn’t work.

Configuration File

Like Steamcast and SHOUTcast, the icecast.conf configuration file contains several op- tions that can be changed. Icecast2 uses an XML configuration approach. See the ICEcast website or the online book referenced above for details.

Stream and Track Names

The iPort sends the LW channel text name to the server, which uses it as the Stream name. The same text is sent as the Track name. However, this is only sent one time, so your source audio application can update the Track name via a direct and independent connection to the server.
