Editor: Video renderer no longer available in Chrome

See original GitHub issue

Describe the bug

The editor’s video renderer relies on a global SharedArrayBuffer constructor. Previously, this was compatible with Chrome and not Firefox.

However API changes have made this condition fail in Chrome too without certain headers present. AFAIK, the video renderer is not visible in any modern browser.

To Reproduce

In Chrome (currently v102.0.5005.61), run 'SharedArrayBuffer' in window. It will evaluate to false, and the video renderer UI will not appear on https://threejs.org/editor

Expected behavior

The video renderer will be visible and functional in the editor on Chrome at least. I have to read more deeply about the new security restrictions, but hopefully this is an easy fix.

Platform:

  • Device: 2018 MacBook Pro
  • OS: MacOS 11.6
  • Browser: Chrome 102.0.5005.61
  • Three.js version: r141

Or we can just use a version without SharedArrayBuffer: https://github.com/ffmpegwasm/ffmpeg.wasm/issues/137#issuecomment-1014956114
