Explication technique
The page calls getUserMedia({video:true}) to trigger the normal permission flow. A successful stream confirms both permission and a usable video track; a rejected promise exposes the browser error name.
Permission state can change outside the page. The Permissions API may expose a camera state in some browsers, but getUserMedia remains the authoritative check for actual access.
Dépannage
No prompt appears
If access is already blocked, the browser may reject immediately. Reset the camera permission for this site.
Permission is granted but no image
Another application may be using the camera. Close it and retry.
Camera not listed
Check the device connection and operating-system privacy settings.
Insecure context warning
Camera access normally requires HTTPS or localhost.
