  "github_readme_excerpt": "# libavif\n\nThis library aims to be a friendly, portable C implementation of the AV1 Image\nFile Format, as described here:\n\n\u003chttps://aomediacodec.github.io/av1-avif/\u003e\n\nIt can encode and decode all AV1 supported YUV formats and bit depths (with\nalpha). In addition to the library, encoder and decoder command line tools are\nalso provided (`avifenc` and `avifdec`).\n\nIt is recommended that you check out/use\n[tagged releases](https://github.com/AOMediaCodec/libavif/releases) instead of\njust using the main branch. We will regularly create new versions as bug fixes\nand features are added.\n\n## Command line tool usage\n\n```sh\navifenc -q 75 input.[jpg|png|y4m] output.avif\navifdec output.avif decoded.png\n```\n\nSee `avifenc --help` for all options.\n\n## API usage\n\nPlease see the examples in the \"examples\" directory. If you\u0027re already building\n`libavif`, enable the CMake option `AVIF_BUILD_EXAMPLES` in order to build and\nrun the examples too.\n\n## Installation\n\n`libavif` is a package in most major OSs.\n\n### Windows\n\n```sh\nvcpkg install libavif\n```\nYou can also download the official windows binaries on the\n[release](https://github.com/AOMediaCodec/libavif/releases) page.\n\n### macOS\n\nHomebrew:\n```sh\nbrew install libavif\n```\nMacPorts:\n```sh\nsudo port install libavif\n```\n\n### Linux\n\nDebian-based distributions:\n```sh\nsudo apt install libavif-dev\n```\nRed Hat-based distributions:\n```sh\nsudo yum -y install libavif\n```\n\n### MinGW\n\nFor the \"default\" MSYS2 UCRT64 environment:\n```sh\npacman -S mingw-w64-ucrt-x86_64-libavif\n```\n\n## Build Notes\n\nBuilding libavif requires [CMake](https://cmake.org/).\nSee [Build Command Lines](#build-command-lines) below for example command lines.\n\n### Controlling Dependencies\n\nCMake flags like `AVIF_CODEC_AOM`, `AVIF_LIBYUV`, etc. allow enabling or\ndisabling dependencies. They can take three possible values:\n* `OFF`: the dependency is disabled.\n* `SYSTEM`: the dependency is expected to be installed on the system.\n* `LOCAL`: the dependency is built locally.

Includes both the C library (for embedding in applications) and CLI tools (avifenc/avifdec) for batch conversions. It\u0027s the reference implementation with broad format support and ties to the AOM codec ecosystem."
