VipsJpeg: Invalid SOS parameters for sequential JPEG

[pathouse]

i'm running into this error when trying to export a jpeg image

from what i can tell govips has no problem loading the jpeg but then it fails to export that same image

i put together a small example repo here that reproduces the problem: https://github.com/pathouse/jpeg-govips

package main

import (
	"io/ioutil"
	"os"
	"fmt"
	"github.com/davidbyttow/govips/v2/vips"
)

func main() {
	img, err := vips.NewImageFromFile("example.jpg")
	if err != nil {
		fmt.Println("error: ", err)
		os.Exit(1)
	}
	imgBytes, _, err := img.ExportJpeg(vips.NewJpegExportParams())
	if err != nil {
		fmt.Println("error: ", err)
		os.Exit(1)
	}
	ioutil.WriteFile("out.jpg", imgBytes, 0644)
}

some searching around the web suggests this is an issue w/ jpegs produced by samsung phones
(lovell/sharp#1578) and that the work around may be ignoring this error?

wondering how i can accomplish that in govips

if there's a code change required i'm happy to try to take that on if you're able to point me in the right direction

edit: full stack trace as well

You can try FailOnError in vips.ImportParams, example code:

NumPages: intMinusOne, is used to make sure GIF images are loaded correctly

package main

import (
	"os"

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

var (
	boolFalse   vips.BoolParameter
	intMinusOne vips.IntParameter
)

func main() {
	vips.LoggingSettings(nil, vips.LogLevelError)
	vips.Startup(nil)
	defer vips.Shutdown()
	boolFalse.Set(false)
	intMinusOne.Set(-1)

	img, err := vips.LoadImageFromFile("invalid.jpg", &vips.ImportParams{
		FailOnError: boolFalse,
		NumPages:    intMinusOne,
	})
	if err != nil {
		panic(err)
	}

	imageBytes, _, _ := img.ExportWebp(&vips.WebpExportParams{
		Quality: 75,
	})

	_ = os.WriteFile("input_webp.webp", imageBytes, 0644)

}

ah thank you @n0vad3v this did indeed resolve the error when i updated my example repo 👍
