It provides the library API plus the `avifenc` and `avifdec` command-line tools used to encode, decode, inspect, and test AVIF images. ### 项目历史 The project was created around the AVIF specification, which maps AV1 image payloads into an ISO base media file format container. The repository copyright text names Joe Drago in 2019, and the codebase grew into an AOMedia-hosted implementation with codec back ends for libaom, dav1d, libgav1, rav1e, and SVT-AV1. The changelog shows the project moving from fast-moving 0.x releases into a 1.0.0 release on 2023-08-24, where the maintainers stated the ABI would be more stable from that point. Later releases added gain-map work, image-sequence handling, stricter parsing, and build/dependency refinements. ### 采用历史 libavif became the practical Unix package for AVIF batch conversion because it ships simple tools and a small C API. Its README documents package-manager installation across Homebrew, MacPorts, Debian-style systems, Red Hat-style systems, MSYS2, and Windows via vcpkg or release binaries. ### 使用方式 Users commonly run `avifenc` to convert JPEG, PNG, or Y4M input to AVIF and `avifdec` to decode AVIF output back to common image formats. Developers link the library when they need AVIF support without embedding the full details of AV1 codec selection, metadata handling, tiling, alpha, gain maps, and color conversion. ### 为什么软件包爱好者会关心 libavif is the tiny command-line face of a much larger codec ecosystem. Package maintainers care about it because optional codec dependencies change feature coverage, performance, binary size, and patent-policy comfort while the same `avifenc` and `avifdec` commands appear in scripts and image pipelines. ### 时间线 - 2019: Repository license text records Joe Drago copyright for libavif. - 2020: Version 0.8.0 adds image sequence encoding and related codec-layer refactoring. - 2023: Version 1.0.0 marks a more stable ABI. - 2024: Version 1.1.0 adds experimental gain-map API work. - 2025: Version 1.2.0 installs `avifgainmaputil` and turns on gain-map API support. - 2026: Version 1.4.2 requires C11 for compilation while keeping public headers C99. ### Related projects - AV1 Image File Format, libaom, dav1d, libgav1, rav1e, SVT-AV1, libyuv, libjpeg, libpng, and image conversion pipelines are the main adjacent projects. ### 来源 - - - ## 安全说明 library-like package without higher-risk signals. -
