Its official README describes fast VMAF sampling, automatic CRF calculation, and FFmpeg/SVT-AV1/VMAF integration, while also supporting other FFmpeg encoders such as libx265 and libx264. ### Project history The GitHub repository was created in January 2022 and the package metadata identifies Alex Butler as the author. The project follows the pattern of small media CLIs that turn a complicated FFmpeg quality-search workflow into a repeatable command. ### Adoption history The supplied package-manager metadata lists ab-av1 in Homebrew, MacPorts, Nix, Scoop, and zypper, which points to cross-platform adoption among users who want reproducible video-encoding tooling without hand-maintaining local scripts. ### How it is used The README documents subcommands such as auto-encode, crf-search, sample-encode, encode, vmaf, and xpsnr. Typical use is to sample an input, choose a CRF that meets a target VMAF or XPSNR quality threshold, then run FFmpeg with the selected settings. ### Why package nerds care Package maintainers care about ab-av1 because it wraps heavyweight multimedia dependencies into one CLI contract: FFmpeg in PATH, SVT-AV1/libvmaf support, and a Rust binary with release artifacts for multiple platforms. ### Timeline - 2022: GitHub repository created. - 2026: v0.11.4 published on GitHub releases. ### Related projects - FFmpeg provides the encoding and probing substrate used by ab-av1. - SVT-AV1, libvmaf, libx265, and libx264 are encoder or quality-analysis components referenced by the official README. ### Sources - Official README, Cargo.toml, GitHub repository metadata, GitHub releases, and source_facts.package-manager. ## Security Notes narrow executable package without higher-risk signals. - **Geiger risk:** green / low - narrow executable package without higher-risk signals ## Source Database Details - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** ab-av1 - **Version Scheme:** 0 - **Revision:** 0 - **Head Version:** HEAD - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** head, stable ## Other Package-Manager Records - Nix - ab-av1: normalized package name match | nixpkgs package indexes: pkgs/by-name/ab/ab-av1/package.nix from https://api.github.com/repos/NixOS/nixpkgs/git/trees/master?recursive=1 - zypper - ab-av1 - 0.11.0-1.2: normalized package name match | openSUSE Tumbleweed package metadata: ab-av1 from https://download.opensuse.org/tumbleweed/repo/oss/repodata/be8d3611d25469107f32075a1697e69ec57a2b850b42348a658cc671ad5ec2b50760d02c3e59524d50da9a11d5be799bdaffba2e166e8ca8858512e3c0bd665d-primary.xml.zst | An AV1 video encoding wrapper | https://github.com/alexheretic/ab-av1 - MacPorts - ab-av1: normalized package name match | MacPorts ports tree: multimedia/ab-av1/Portfile from https://api.github.com/repos/macports/macports-ports/git/trees/master?recursive=1 - Scoop - extras/ab-av1: normalized package name match | Scoop official bucket manifest trees: bucket/ab-av1.json from https://api.github.com/repos/ScoopInstaller/Extras/git/trees/master?recursive=1 ## Related links - [Source-control packages](https://www.automicvault.com/pkg/source-control-tools/) - Belongs to a source-control command family. - [Terminal utility packages](https://www.automicvault.com/pkg/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Networking and protocol packages](https://www.automicvault.com/pkg/networking-protocol-tools/) - Matched network, protocol, or remote-service metadata. - [Media and graphics packages](https://www.automicvault.com/pkg/media-graphics-tools/) - Matched media, image, audio, video, or graphics metadata. - [ffmpeg](https://www.automicvault.com/pkg/brew/ffmpeg/) - Runtime dependency declared by Homebrew. - [rust](https://www.automicvault.com/pkg/brew/rust/) - Build dependency declared by Homebrew. - [av1an](https://www.automicvault.com/pkg/brew/av1an/) - Shares av.db curated category or tags: av1, cli, encoding, media, video. - [aom](https://www.automicvault.com/pkg/brew/aom/) - Shares av.db curated category or tags: av1, cli, media, video. - [dav1d](https://www.automicvault.com/pkg/brew/dav1d/) - Shares av.db curated category or tags: av1, cli, media, video. - [ffmpegthumbnailer](https://www.automicvault.com/pkg/brew/ffmpegthumbnailer/) - Shares av.db curated category or tags: cli, ffmpeg, media, video. - [ffms2](https://www.automicvault.com/pkg/brew/ffms2/) - Shares av.db curated category or tags: cli, ffmpeg, media, video. - [handbrake](https://www.automicvault.com/pkg/brew/handbrake/) - Shares av.db curated category or tags: cli, encoding, media, video. - [kvazaar](https://www.automicvault.com/pkg/brew/kvazaar/) - Shares av.db curated category or tags: cli, media, video-encoding. - [mjpegtools](https://www.automicvault.com/pkg/brew/mjpegtools/) - Shares av.db curated category or tags: cli, encoding, media, video. - [video-compare](https://www.automicvault.com/pkg/brew/video-compare/) - Both packages work with overlapping file formats or content types.
