How to access webcam with Javascript [duplicate]

I google'd quite a while about this topic, without any satisfying result. Actually my basic question is: Is there any possible way to access a webcam with Javascript ?

Maybe with HTML5 ? <video> element ?

What are options as developer to access the computers webcam anyway?

Can JavaScript access webcam?

We can access the user device Webcam and microphone using an ECMAScript object navigator. mediaDevices. getUserMedia(constraints). So, the getUserMedia() function by default seek user permission to use your Webcam.

How do you trigger a webcam?

To open up your webcam or camera, select the Start button, then select All apps, and then select Camera in the list of apps. If you have multiple cameras, you can switch between them by selecting Change Camera at the top right once the Camera app is opened.

How do I access my camera in HTML?

With navigator. getUserMedia() , we can finally tap into webcam and microphone input without a plugin. Camera access is now a call away, not an install away.
