Memory overflow when convert large size jpeg to avif #444

Closed Hanmo123 closed 2 months ago

Hanmo123 commented 2 months ago

I tried to convert a image(from Hasselblad x2d, 100 million pixels, about 65MB, you can download here) to avif using codes below:

package main

import (
    "os"

    "github.com/davidbyttow/govips/v2/vips"
)

func main() {
    vips.Startup(nil)
    defer vips.Shutdown()

    image1, _ := vips.NewImageFromFile("thomas-x2d-xcd-25v-1.jpg")
    ep := vips.NewAvifExportParams()
    imageBytes, _, _ := image1.ExportAvif(ep)
    os.WriteFile("output.avif", imageBytes, 0644)
}

it takes more than 13GB memory and finally OOM: image

why i suppose it is abnormal:

import sharp from 'sharp';
sharp('thomas-x2d-xcd-25v-1.jpg').jpeg().toFile('output.avif')

Hey @Hanmo123. Thanks for the issue report. I believe it's probably not a memory leak but instead just has to do with how slow golang's garbage collector works. Try running short-running goroutines that handle the images for instance, or use the gc-functions in the golang standard library.
