## Project history and usage

ab-av1 is a Rust command-line tool for AV1-oriented video encoding workflows. 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.
