AVIF image serializer (muxer)

Minimal writer for AVIF header structure. This is lean, safe-Rust alternative to libavif. It creates the jungle of MPEG/HEIF/MIAF/ISO-BMFF "boxes" as appropriate for AVIF files. Supports alpha channel embedding.

Compatible with decoders in Chrome 85+, libavif v0.8.1, and Firefox 92. It's used in cavif and other encoders.

Together with rav1e, it allows pure-Rust AVIF image encoding.

Requirements

Usage

  1. Compress pixels using an AV1 encoder, such as rav1e. libaom works too.

  2. Call avif_serialize::serialize_to_vec(av1_data, None, width, height, 8)

See ravif crate sources for example usage.
