* Update libavif (v1.0.0-main) * Update libavif for improved compression and speed * v1.0.0 deprecates usage of min and max-quantizers; we use `quality` and `qualityAlpha` instead * Renamed `maxSpeed` to `MAX_EFFORT` for better readability * Update libavif (v1.0.1-main) * Refactor variable names for clarity * Update libaom (v3.7.0) * Add checks for API return values * Rename variables for readability Changes `cqlevel` to `quality`, and `cqAlphaLevel` to `qualityAlpha` * Minor patches in logic * Minor patches in lossless calculation * Add chroma subsampling options to AVIF * Add skeleton for sharp downsampling param * Try to use libsharpyuv * Encoder working, decoder isnt * Make sure sharpyuv is disabled for decoder * Add AVIF_LOCAL flags for sharp yuv * Get AVIF sharp YUV working * Clean up AVIF makefiles * AVIF: Make sharpyuv conditional on subsample * AVIF: Flags to speed up sharpyuv build * AVIF: Minor refactoring in enc.cpp * AVIF: Minor refactoring & renaming * AVIF: Use smart pointers to prevent memory leaks * AVIF: Minor refactoring * AVIF: Revert defaultoptions logic change --------- Co-authored-by: Surma <surma@surma.dev> Co-authored-by: Jake Archibald <jaffathecake@gmail.com>
AVIF encoder
- Source: https://github.com/AOMediaCodec/libavif
- Version: v0.5.4
Example
Run example.js
API
Uint8Array encode(std::string image_in, int image_width, int image_height, AvifOptions opts)
Encodes the given image with given dimension to AVIF. Options looks like this:
struct AvifOptions {
// 0 = lossless
// 63 = worst quality
int minQuantizer;
int maxQuantizer;
// [0 - 6]
// Creates 2^n tiles in that dimension
int tileRowsLog2;
int tileColsLog2;
// 0 = slowest
// 10 = fastest
int speed;
// 0 = 4:2:0
// 1 = 4:2:2
// 2 = 4:4:4
int subsample;
