Shoutcast

Icecast is a free, open source streaming media server that supports audio and video formats, including Ogg (Vorbis, Theora), Opus, WebM, and MP3. It enables the creation of Internet radio stations, private jukeboxes, or other streaming setups, and is versatile, new formats can be added relatively easily thanks to its support for open-standard communication and interaction. Components include the server program itself, libshout (a library for communicating with Icecast servers), and IceS (a source client that sends audio data, either from disk or live captures, to the server). Icecast operates in a client-server model, where source clients originate streams, and the Icecast server relays them to listeners, with support for multiple mountpoints so different streams can coexist on one server. It provides a built-in administration interface and stats pages (HTML, XML, and JSON), exposing runtime information such as active connections, cumulative counters, listener numbers, etc.
