What are the steps to reproduce?

1. Install sharp@0.23.0 or sharp@0.23.1
2. Download sample image as input.gif
3. Save below code to test.js and run node test.js

'use strict';
const fs = require('fs');
const sharp = require('sharp');
const sharpPkg = require('sharp/package.json');
const os = require('os');

const FIXTURE_PATH = 'input.gif';

const suites = [{
  label: 'with sharp(filename)',
  test: async () => {
    await sharp(FIXTURE_PATH, { failOnError: false }).metadata();
  },
}, {
  label: 'with sharp(buffer)',
  test: async () => {
    await sharp(fs.readFileSync(FIXTURE_PATH, { failOnError: false })).png().toBuffer();
  },
}];

(async () => {
  console.log('%s %s', os.platform(), os.arch());
  console.log('using sharp %s. sharp.versions: ', sharpPkg.version, sharp.versions);

  for (const suite of suites) {
    console.log('Trying %s', suite.label);

    try {
      await suite.test();
      console.log('PASSED %s', suite.label);
    } catch (e) {
      console.error('FAILED %s', suite.label);
      console.error(e);
    }
  }
})().catch(console.error);

What is the expected behaviour?

Transformation should work.

Are you able to provide a standalone code sample, without other dependencies, that demonstrates this problem?

Yes, See upper section. Also Screencast is available: https://asciinema.org/a/AZ7Z3wDn2Ro8oEcwq1pZE0gPe

Are you able to provide a sample image that helps explain the problem?

Yes. https://test-mooyoul.s3-accelerate.amazonaws.com/public/sharp-gif-regression/input.gif

Oh, Thanks for the keyword. I owe you so many things 🙏I really like sharp. Thank you for making this cool software!

@mooyoul I think the Samsung firmware is misusing JPEG markers for some kind of metadata but I’ve not looked into it. There’s a lot of evidence of the problem out on the web e.g. https://www.google.com/search?q=“Invalid+SOS+parameters”+samsung
