About Icecast 2

Icecast is a streaming media server which currently supports Ogg (Vorbis and Theora), Opus, WebM and MP3 audio streams.
It can be used to create an Internet radio station or a privately running jukebox and many things in between. It is very versatile in that new formats can be added relatively easily and supports open standards for communication and interaction.

Icecast is distributed under the GNU GPL, version 2.

Icecast Release 2.5 beta1

We are pleased to announce Icecast 2.5 beta1 (2.4.99.1). This is a beta release and not recommended for production use. A summary of the changes is listed below, for details please refer to the ChangeLog.

Downloads

• Source: icecast-2.5-beta1.tar.gz
• Windows icecast_win32_2.5-beta1.exe

New features

• replaces old style items
• triggers
• replaces and offers more functionality
• additional stream metadata exposed
• additional stats XML output (e.g. listeners, used by e.g. licensing services, may need ?omode=legacy)

Known issues

• HTTP PUT implementation currently doesn’t support chunked encoding yet.
• HTTP PUT with “Expect: 100-Continue” receives first a “100” and soon after a “200”, instead of the “200” at the end of transmission.
• Caution should be exercised when using <on-connect> or <on-disconnect>, as there is a small chance of stream file descriptors being mixed up with script file descriptors, if the FD numbers go above 1024. This will be further addressed in the final release.
• Login problems for admin if mount has auth defined (fixed in git for next beta)
• JSON exposes listener details if queried with mount (fixed in git for next beta)

Known issues

• HTTP PUT implementation currently doesn’t support chunked encoding yet.
• HTTP PUT with “Expect: 100-Continue” receives first a “100” and soon after a “200”, instead of the “200” at the end of transmission.
• Caution should be exercised when using <on-connect> or <on-disconnect>, as there is a small chance of stream file descriptors being mixed up with script file descriptors, if the FD numbers go above 1024. This will be further addressed in the next Icecast release.
• Don’t use comments inside <http-headers> as it will prevent processing of further <header> tags.
• Webinterface shows Login when using just stream_auth.
