Hi ankitgalaxy1994,

Actually, it's related to your camera resolution capability. WebRTC choosing resolution automatically according to your camera. Btw, you can define some changes for mediaConstraints.

var mediaConstraints = {

video: {

width: { min: 480, ideal: 1280, max: 1920 },

height: { min: 360, ideal: 720, max: 1080 }

},

audio: true

}

I hope, I could help you.

After setting video constraints screen sharing doesn't work.

Hi Shreeyansh,

You need to configure media constraints according to your requirements.

As I know, screen share using a 1080p resolution. So if you use 720p for ideal, it's normal that it won't work. You shouldn't use 720p resolution as an "ideal" parameter for screen sharing.
