I cloned a project about real-time image processing on a web browser from this link: Then I could not allow my browser to access my camera. I got this javascript alert:
To ignore Chrome’s secure origin policy, follow these steps.
Navigate to chrome://flags/#unsafely-treat-insecure-origin-as-secure in Chrome.
Find and enable the Insecure origins treated as secure section (see below).
Add any addresses you want to ignore the secure origin policy for. Remember to include the port number too (if required).
Save and restart Chrome.
I found solution from below link.Hope it will help to someone
