## プロジェクトの歴史と使われ方

Icecast is Xiph.Org's free streaming media server, historically associated with internet radio and open audio formats. The Homebrew formula packages the server daemon that receives source-client streams and serves them to listeners over network mountpoints.

### プロジェクトの歴史

Icecast's public news archive shows active releases and community use in early 1999, including Icecast 1.1.4 and live broadcast notes. It became part of the Xiph.Org multimedia stack, aligned with the foundation's goal of open protocols and software for internet media.

Icecast 2 was a major rewrite for the 2000s streaming world. The 2.0.0 announcement says it followed years of development and alpha testing and supported Ogg Vorbis and MP3 streaming. Later documentation describes Icecast as versatile server software for internet radio, private jukeboxes, and other multimedia streams.

### 採用の歴史

Icecast spread because it solved a practical hosting problem: a station or broadcaster could run a server, point one or more source clients at mountpoints, and publish streams without proprietary broadcast infrastructure. Xiph's public directory still centers on Icecast streams, reinforcing its role as infrastructure for internet radio discovery.

Package-manager adoption is broad because the server is a classic Unix daemon with a single XML configuration file and a long-lived operational model. The input metadata lists packages across Homebrew, Alpine, Fedora, MacPorts, Nix, Scoop, and openSUSE.

### 使われ方

Users run `icecast` as a streaming server, configure passwords and mount behavior in `icecast.xml`, then connect source clients that publish audio or video streams. Icecast creates mountpoints as sources connect, and listeners access those mountpoints over HTTP.

The FAQ warns users to start from the default config and change only the passwords before adding more settings, which fits the server's long history of copy-pasted and overgrown configurations.

### パッケージ好きにとっての重要性

Icecast is package-nerd significant because it is one of the canonical open-source internet-radio daemons. Installing it from a package manager turns a general-purpose machine into a streaming relay with a familiar service/config file shape.

It also anchors several nearby packages and concepts: source clients, Xiph codecs, public stream directories, and the old but durable vocabulary of mounts, listeners, and internet radio servers.

### タイムライン

- 1999: Icecast news posts document active 1.x releases and broadcasts.
- 2004: Icecast 2.0.0 was announced after years of development and alpha testing.
- 2014: Icecast 2.4.1 documentation describes Ogg Vorbis and MP3 streaming plus Unix and Windows support.
- 2016: The Xiph GitLab project for the server was created.
- 2025: GitLab tags include the 2.5.0 release line.

### Related projects

- Xiph.Org projects such as Vorbis, Opus, FLAC, and Theora are part of the same open multimedia ecosystem.
- IceS is the related Xiph source-client project for feeding streams into Icecast.
- dir.xiph.org is the public Icecast stream directory.
