Till now we’ve seen Chrome and Edge displaying Media Control Overlays for YouTube Videos when media keys are pressed, Google Chrome now introduced “Global Media Controls UI” in Canary version 77 and it can be enabled and seen from the toolbar. The Global Media Controls (GMC), unlike to overlays neither require media keys usage nor disappear immediately, can be seen anytime when YouTube videos are playing by clicking toolbar icon.

We’ve covered Chromium browsers showing YouTube video info in an overlay, Microsoft worked with Google to bring this feature to Chromium on Windows. Behind the scenes, YouTube website via Media Session API provides metadata about video title, artist name, and company information to Chrome/Edge browser which then will be displayed in an overlay.
Today Google added a flag Chrome Canary to enable Global Media Controls UI on Windows, Mac, and Linux. If you enable this flag, a play icon will appear on the toolbar when media controllable sessions are active, clicking the icon displays media controls UI that shows Play/Pause, Previous, next controls along with video info as we mentioned above.
