Introduction to libavif

Project Introduction

Kunpeng Image Library (KIL) uses methods such as vector optimization, algorithm optimization, and workflow optimization to improve the image encoding performance of libavif.

libavif is an image library based on the AV1 codec to process AVIF images. AVIF is known for its advanced compression algorithm, which provides extremely small file sizes while retaining high-quality details. It is especially suitable for scenarios that require high image quality with limited bandwidth or storage, such as cover images on mobile devices or online video platforms.
