## Historique du projet et usages

libilbc is a packaging-focused standalone copy of the Internet Low Bit Rate Codec implementation from the WebRTC project. 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.

### Historique du projet

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.

### Historique d'adoption

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.

### Modes d'utilisation

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.

### Pourquoi les passionnés de paquets s'y intéressent

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.

### Chronologie

- 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.
