go-avif 
go-avif implements AVIF (AV1 Still Image File Format) encoder for Go using libaom, the high quality AV1 codec.
Requirements
Make sure libaom is installed. On typical Linux distro just run:
Debian (and derivatives):
sudo apt-get install libaom-devRHEL (and derivatives):
sudo dnf install libaom-develUsage
To use go-avif in your Go code:
import "github.com/Kagami/go-avif"To install go-avif in your $GOPATH:
go get github.com/Kagami/go-avifFor further details see GoDoc documentation.
Example
package main
import (
"image"
_ "image/jpeg"
"log"
"os"
"github.com/Kagami/go-avif"
)
func main() {
if len(os.Args) != 3 {
log.Fatalf("Usage: %s src.jpg dst.avif", os.Args[0])
}
srcPath := os.Args[1]
src, err := os.Open(srcPath)
if err != nil {
log.Fatalf("Can't open sorce file: %v", err)
}
dstPath := os.Args[2]
dst, err := os.Create(dstPath)
if err != nil {
log.Fatalf("Can't create destination file: %v", err)
}
img, _, err := image.Decode(src)
if err != nil {
log.Fatalf("Can't decode source file: %v", err)
}
err = avif.Encode(dst, img, nil)
if err != nil {
log.Fatalf("Can't encode source image: %v", err)
}
log.Printf("Encoded AVIF at %s", dstPath)
}CLI
go-avif comes with handy CLI utility avif. It supports encoding of JPEG and
PNG files to AVIF:
# Compile and put avif binary to $GOPATH/bin
go get github.com/Kagami/go-avif/...
# Encode JPEG to AVIF with default settings
avif -e cat.jpg -o kitty.avif
# Encode PNG with slowest speed
avif -e dog.png -o doggy.avif --best -q 15
# Lossless encoding
avif -e pig.png -o piggy.avif --lossless
# Show help
avif -hStatic 64-bit builds for Windows, macOS and Linux are available at releases page. They include latest libaom from git at the moment of build.
Display
To display resulting AVIF files take a look at software listed here. E.g. use avif.js web viewer.
