## プロジェクトの歴史と使われ方

dav1d is VideoLAN's small, fast, cross-platform AV1 decoder, written in C and assembly and designed for broad embedding.

### プロジェクトの歴史

The dav1d README describes a decoder focused on speed and correctness, created to overcome the early lack of AV1 hardware decoding. It identifies the VideoLAN GitLab repository as canonical and notes partial funding by the Alliance for Open Media.

### 採用の歴史

The project became package-manager-relevant because AV1 needed a fast software decoder on desktops, mobile systems, and other platforms before hardware support was universal. Its roadmap highlights portability, SIMD work, and architecture-specific optimization.

### 使われ方

Package users install the command-line tool and library when they need AV1 decoding support, tests, benchmarks, or downstream multimedia software linked against a permissively licensed decoder.

### パッケージ好きにとっての重要性

dav1d is significant because it made AV1 decoding practical as a small system package: fast enough for real playback, permissively licensed, and maintained by a media-toolchain community.

### タイムライン

- 2018: dav1d development begins in the early AV1 software-decoder era.
- 2023: 1.x releases continue with new SIMD and API work.
- 2025: 1.5.x releases focus on maintenance and architecture optimizations.

### Related projects

- Related projects include AV1, Alliance for Open Media, VideoLAN, VLC, FFmpeg, libaom, and platform SIMD toolchains.
