Firefox – which has disabled SharedArrayBuffer as of January 2018 to mitigate Meltdown/Spectre.

I just tried the demo on https://ffmpegwasm.github.io/vue-app/

Using Chrome Version 92.0.4515.107 64 bits

@jaronwanderley Is is still not working ?

I have no issue and I can't reproduce the bug.

Yep, still there on https://ffmpegwasm.github.io/vue-app/ : Linux chrome Version 92.0.4515.131 64 bits:

[Deprecation] SharedArrayBuffer will require cross-origin isolation as of M92, around July 2021. See https://developer.chrome.com/blog/enabling-shared-array-buffer/ for more details.

You can try that on Linux :

• Quit any running instance of Chrome.
• Run your favorite terminal emulator.
• In the terminal, run commands like below

google-chrome --enable-features=SharedArrayBuffer

source (with mac & windows instructions as well) : https://web.dev/cross-origin-isolation-guide/

Ideally you'd have to set HTTP headers for cross origin isolation, my solution is just a fix for local development.

[cclaan]

Adding cross origin headers to the vue.config.js fixed this for me locally

const path = require('path');
const express = require('express');

module.exports = {
  publicPath: process.env.NODE_ENV === 'production'
    ? '/vue-app/'
    : '/',
  configureWebpack: {
    devServer: {
      before: app => {
        app.use('/node_modules/', express.static(path.resolve(__dirname, 'node_modules')))
      },
      headers: { "Cross-Origin-Embedder-Policy" : "require-corp",
                  "Cross-Origin-Opener-Policy" : "same-origin" }
    }
  }
};

[BrunoQuaresma]

Is it only possible to make that work by setting the require-corp and same-origin headers?
