AVIF: Creating a new image format in the open
summary
AVIF is the browser-backed image format based on the AV1 codec that promises much smaller files and wider color: a claim of ~50% smaller than JPEG shows up in testing. Implementation includes a Rust-based MP4 parser integrated into Firefox, coordination with libavif/Chrome, use of libyuv for YUV→RGB, CICP and ICC handling, and fixes for the CLAP privacy corner case. Work faces early rollbacks for color and container quirks but ultimately ships (Firefox 93) after interoperability patches.
