The official project page describes it as a codec for resolutions from QCIF to HDTV, progressive or interlaced, using wavelets, motion compensation, and arithmetic coding. ### プロジェクトの歴史 The SourceForge project was registered in February 2004 and organized its downloads around the Dirac codec, DirectShow filter builds, ffmpeg2dirac sources and binaries, old integration patches, and sample video. Its licenses are listed as MPL 1.1, GPLv2, and LGPLv2, matching the multi-license style of codec libraries and tools from that period. ### 採用の歴史 Dirac's adoption footprint is clearest in its SourceForge file tree and historical integration patches for projects such as FFmpeg, MPlayer, and transcode. Those artifacts show how codec projects of the 2000s often spread through patches, filters, command-line encoders and decoders, and downstream multimedia packages before settling into older repository maintenance. ### 使われ方 The Homebrew formula exposes many conversion helpers plus `dirac_encoder`, `dirac_decoder`, and `dirac_instrumentation`. In package-manager terms, Dirac is used as a codec library and toolset rather than as an application with user-level configuration. ### パッケージ好きにとっての重要性 Dirac matters historically as an open video-codec package from the SourceForge era, with a visible trail of codec sources, DirectShow components, FFmpeg and MPlayer patches, and format-conversion utilities. It is the kind of multimedia package that persists in package managers because older media workflows and build dependencies may still expect it. ### タイムライン - 2004: SourceForge project registered. - 2009: SourceForge files list dated Dirac codec and DirectShow filter folders. - 2011: ffmpeg2dirac Windows binary appears in the SourceForge download list. - 2015: SourceForge activity feed records old integration patch file releases. - 2017: SourceForge activity feed shows later bug reports against the project. ### Related projects - Official SourceForge file listings include ffmpeg2dirac, a Dirac DirectShow filter, old FFmpeg and MPlayer patches, transcode patches, and sample video assets. ### ソース - - - ## セキュリティノート broad file, network, media, or database tool signal. -
