Animated GIF to WEBP using a Sharp stream is not animated anymore #2362
Description
The installation went well, and I managed to make it work with a file or an URL for the input and a file for the output, but i don't manage to find a way to get it animated when using a stream for the output.
@deftomat Sorry for bothering you, but I think you might have a quick answer 👼
Are you using the latest version? Is the version currently in use as reported by npm ls sharp the same as the latest version as reported by npm view sharp dist-tags.latest?
Yes
What are the steps to reproduce?
const app = new Koa();
const router = new Router();
const agent = require('superagent');
const sharp = require('sharp');
router.get('/:spec/i.:extension', ctx => {
let sharpStream = sharp() // WORKING BUT NOT ANIMATED
let sharpStream = sharp({ animated: true }) // Error [ERR_STREAM_DESTROYED]: Cannot call write after a stream was destroyed
let sharpStream = sharp({ pages: -1 }) // Error [ERR_STREAM_DESTROYED]: Cannot call write after a stream was destroyed
let sharpStream = sharp(undefined, { pages: -1 }) // Error: Unsupported input 'undefined' of type undefined when also providing options of type object
let sharpStream = sharp(undefined, { animated: true }) // Error: Unsupported input 'undefined' of type undefined when also providing options of type object
sharpStream = sharpStream.toFormat('webp', {
quality,
pages: -1, // doesn't change anything
animated: true, // doesn't change anything
});
ctx.set('Content-Type', 'image/webp');
ctx.body = agent.get(url).pipe(sharpStream);
ctx.status = 200;
});What is the expected behaviour?
The output stream webp image should be animated.
Are you able to provide a minimal, standalone code sample, without other dependencies, that demonstrates this problem?
Kind of, please see below.
Are you able to provide a sample image that helps explain the problem?
I used this image.
