履歴

プロジェクトの歴史と使われ方

libdca is VideoLAN's free C library for decoding DTS Coherent Acoustics streams. It began as libdts/dcadec, was based on a52dec, and became a small but recognizable codec package in Unix multimedia stacks.

プロジェクトの歴史

VideoLAN's project page says the code was written by Gildas Bazin, based on a52dec, and released under the GPL. The repository README preserves the older libdts naming, describes goals of portability, reusability, precision, and speed, and notes that VLC was the primary project using it in the early README text.

The NEWS file records dcadec 0.0.1 on 8 February 2004 as the first public release, followed by libdca/libdts releases through 0.0.7. Version 0.0.3 in April 2007 changed the library name to libdca from libdts, and later 2018 and 2020 releases were mostly build-system and maintenance fixes.

採用の歴史

libdca's adoption came through DVD and media-player ecosystems that needed DTS Coherent Acoustics decoding. VideoLAN documents the standard's use in DVD, DTS audio CD, and radio broadcasting, and the library naturally fit VLC and other package-manager multimedia dependency sets.

使われ方

The library is linked by media software for DTS/DCA decoding, while dcadec acts as a test and proof-of-concept decoder. The README documents decoding raw DTS Coherent Acoustics streams and multiplexed MPEG program streams, plus output options for downmixing, performance testing, and conformance testing.

パッケージ好きにとっての重要性

libdca is a compact codec-library package with a naming story, standards tie-in, GPL licensing, VideoLAN ownership, and command-line tools. It is the sort of package that reveals how codec support historically entered Unix distributions as small libraries around bigger media players.

タイムライン

  • 2004: dcadec 0.0.1 was released as the first public release of libdca, then known as libdts.
  • 2004: libdca 0.0.2 added high-frequency vector-quantization support and packaging work.
  • 2007: libdca 0.0.3 changed the library name from libdts to libdca.
  • 2007: libdca 0.0.5 fixed a header typo after shared-library and build-system fixes.
  • 2018: libdca 0.0.6 shipped mostly build-system bug fixes.
  • 2020: libdca 0.0.7 shipped build-system fixes and a potential out-of-bound access fix.

Related projects

  • a52dec is the direct codebase ancestor named by VideoLAN. VLC media player is the early user named by upstream, and DTS Coherent Acoustics / ETSI TS 102 114 is the codec standard behind the package.
