libavif-sys

AVIF is an image codec based on the next-generation open, royalty-free video coding format AV1.

AVIF gets compression ratios considerably better than JPEG for similar quality levels.

This crate wraps the Alliance for Open Media's libavif into an unsafe rust crate.

Minimal safe wrappers are provided by libavif and a image-compatible libavif-image.

Codec Features

This crate, by default, uses codec-dav1d for decoding and codec-rav1e for encoding, because they have the best (speed) performance. You can disable those features and instead use codec-aom.

Compiling

• cmake is required for compiling the crate.
• dav1d requires ninja/meson and nasm
• rav1e is implemented in Rust and has no other dependencies (though note that libavif itself uses it via rav1e's C-API).

Platform support

This crate is only expected to compile on Linux. Patches accepted.
