It identifies the VideoLAN GitLab repository as canonical and notes partial funding by the Alliance for Open Media. ### 采用历史 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. ### 使用方式 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. ### 为什么软件包爱好者会关心 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. ### 时间线 - 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. ### 来源 - - - ## 安全说明 narrow executable package without higher-risk signals. - **Geiger 风险:** 绿色 / 低 -
