Its package value is that it turns a codec otherwise embedded in a much larger communications stack into a small system library and test utility. ### プロジェクトの歴史 The underlying iLBC codec was specified for the IETF in RFC 3951, published in December 2004, with RFC 3952 defining the RTP payload format for carrying iLBC speech. The libilbc repository packages WebRTC's implementation as a distributable library rather than requiring consumers to vendor a WebRTC source subtree. Timothy Gu took over maintainership for the standalone package in the 2.0.0 release dated November 17, 2014, updated the bundled WebRTC source, cleaned the Autotools files, and added CMake support. Version 3.0.0 on December 18, 2020 updated again to WebRTC source r32829, removed Autotools, made CMake the build system, and introduced the installed ilbc_test utility. ### 採用の歴史 Adoption is mainly through distribution packaging and projects that need the iLBC codec without a full WebRTC dependency. The README explicitly targets packagers, and Homebrew, Nix, and Arch package metadata all carry the package under the libilbc name. ### 使われ方 Typical use is linking against the C library for iLBC encode and decode support or running ilbc_test against raw 8 kHz mono PCM samples. The codec remains relevant where narrowband speech compatibility and packet-loss behavior matter more than modern wideband audio quality. ### パッケージ好きにとっての重要性 For package maintainers, libilbc is a classic extraction package: it keeps a small, ABI-versioned codec library available without forcing each downstream to track WebRTC internals. The 2020 CMake-only release also made the package easier to integrate into cross-platform build systems. ### タイムライン - 2004-12: RFC 3951 specified iLBC as an experimental Internet codec, and RFC 3952 specified its RTP payload format. - 2014-11-17: libilbc 2.0.0 moved under Timothy Gu's maintainership and refreshed the WebRTC source snapshot. - 2014-12-14: libilbc 2.0.2 fixed release-tarball and shared-library packaging details. - 2020-12-18: libilbc 3.0.0 updated to WebRTC source r32829 and made CMake the only build system. - 2020-12-31: libilbc 3.0.4 fixed a Chromium issue and upstreamed local patches to WebRTC. ### Related projects - Related projects include WebRTC, which supplies the codec implementation packaged here; the IETF iLBC RFCs that define the codec and RTP payload; and downstream multimedia or telephony packages that prefer a small standalone codec library. ### ソース - - - - - - ## セキュリティノート library-like package without higher-risk signals. - **Geiger リスク:** グリーン / 低 - library-like package without higher-risk signals ## ソースデータベース詳細 - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** libilbc - **Version Scheme:** 0 - **Revision:** 0 - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** stable ## 他のパッケージマネージャ記録 - Nix - libilbc: normalized package name match | nixpkgs package indexes: pkgs/by-name/li/libilbc/package.nix from https://api.github.com/repos/NixOS/nixpkgs/git/trees/master?recursive=1 - pacman - libilbc - 3.0.4-4: normalized package name match | Arch Linux sync databases: libilbc from https://geo.mirror.pkgbuild.com/extra/os/x86_64/extra.db.tar.gz | A friendly copy of the iLBC codec from the WebRTC project | https://github.com/TimothyGu/libilbc/ ## 関連リンク - [Source-control packages](https://www.automicvault.com/ja/pkg/source-control-tools/) - Belongs to a source-control command family. - [Terminal utility packages](https://www.automicvault.com/ja/pkg/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Networking and protocol packages](https://www.automicvault.com/ja/pkg/networking-protocol-tools/) - Matched network, protocol, or remote-service metadata. - [Media and graphics packages](https://www.automicvault.com/ja/pkg/media-graphics-tools/) - Matched media, image, audio, video, or graphics metadata. - [cmake](https://www.automicvault.com/ja/pkg/brew/cmake/) - Build dependency declared by Homebrew. - [adplug](https://www.automicvault.com/ja/pkg/brew/adplug/) - Shares av.db curated category or tags: audio, cli, library, media. - [alsa-lib](https://www.automicvault.com/ja/pkg/brew/alsa-lib/) - Shares av.db curated category or tags: audio, cli, library, media. - [chromaprint](https://www.automicvault.com/ja/pkg/brew/chromaprint/) - Shares av.db curated category or tags: audio, cli, library, media. - [fluid-synth](https://www.automicvault.com/ja/pkg/brew/fluid-synth/) - Shares av.db curated category or tags: audio, cli, library, media. - [freealut](https://www.automicvault.com/ja/pkg/brew/freealut/) - Shares av.db curated category or tags: audio, cli, library, media. - [id3lib](https://www.automicvault.com/ja/pkg/brew/id3lib/) - Shares av.db curated category or tags: audio, cli, library, media. - [libdca](https://www.automicvault.com/ja/pkg/brew/libdca/) - Shares av.db curated category or tags: audio, cli, library, media. - [libheif](https://www.automicvault.com/ja/pkg/brew/libheif/) - Shares av.db curated category or tags: cli, codec-library, library, media. - [codec2](https://www.automicvault.com/ja/pkg/brew/codec2/) - Both packages work with overlapping file formats or content types.
