Ambient light for YouTube: free Ambilight-style glow right in your browser
TL;DR
Ambient light for YouTube is an open-source browser extension that uses WebGL to analyse video colours in real time and project a glow around the player — an Ambilight-style effect with no extra hardware.
Highlights
| Feature | Details |
|---|---|
| Real-time glow | Uses WebGL to read video colours and render a smooth glow around the frame. |
| Ultrawide-friendly | Detects and crops black bars, scaling video to fill the screen. |
| Deep customisation | Tune blur, spread, debanding and an FPS limit. |
| Open source | Available for Chrome and Firefox. |
How to put it to work
- Great for an entertainment setup, or for watching long talks in a dark room with less eye strain.
- On low-end machines or laptops on battery, cap the effect’s FPS to reduce GPU load.
- For frontend developers: a nice real-world example of browser-side video processing with WebGL.
