YouTube Ambient Mode, everywhere on Windows.
YouTube's Ambient Mode is great, but it's trapped inside a web browser. The moment you fullscreen, open VLC, play PC games, or listen to music, the glow disappears. Oblyus brings native ambient lighting to your entire desktop.
The problem with browser extensions
Why browser-based solutions fall short compared to a native Windows compositor.
Trapped in the web tab
- ✕Only works while viewing youtube.com inside an active browser tab.
- ✕Zero support for VLC, PotPlayer, MPV, or offline movie files.
- ✕Does not react to desktop music players like Spotify or Apple Music.
- ✕Heavy DOM manipulation and canvas sampling increases CPU/battery drain.
System-wide native immersion
- ✓Works over any video player, fullscreen stream, or game on Windows 10 & 11.
- ✓Smart letterbox detection ignores 2.39:1 widescreen black bars.
- ✓Music Mode pulses with the beat of whatever your PC plays.
- ✓Native DirectX DirectComposition hardware overlay at only 0.3% CPU.
Profiles that adapt to whatever you open
You shouldn't have to toggle settings every time you switch tasks. Oblyus detects the frontmost application and changes its lighting behavior seamlessly:
Frequently Asked Questions
Why do I need Oblyus if YouTube already has Ambient Mode?
YouTube's built-in Ambient Mode only functions inside a browser window on youtube.com. When you go into true fullscreen, watch movies in desktop players like VLC or MPC-HC, play games, or stream on other platforms, YouTube's effect does not exist. Oblyus brings that exact cinematic glow to your entire Windows operating system.
How does Oblyus compare to Chrome ambient light extensions?
Browser extensions run inside Chrome's JavaScript sandbox, which can cause frame drops on 4K 60fps video and high CPU usage. Oblyus is a native, statically compiled C++ application utilizing Windows DirectComposition and DXGI desktop duplication at 0.3% CPU, with zero browser overhead.
Does it work with widescreen movies with black bars?
Yes. Oblyus features built-in letterbox boundary detection. When you watch 2.39:1 widescreen films or videos, it detects the black borders and samples the true cinematic picture inside, ensuring vibrant colors glow around your monitor.
Can it switch modes automatically when I open Spotify or a video?
Yes. Oblyus features App Profiles. You can configure it to automatically use Ambient mode when VLC or your browser opens, and switch to Music mode when Spotify or Apple Music is active.
