My goal is to enable screen sharing in the middle of a video or audio call using webrtc web application .

Well I found that I can use MediaStreamTrack.applyConstraints() to change video property but is it possible to change the video source ? further more how can I add video to an existing audio stream .

I need this to work on chrome only for now .

localStream.stop();

peerconnection.removeStream(localStream);

I was able to find the solution by following steps

remove the current stream

add new stream

create new offer

Note that removeStream is deprecated and no longer in the spec, and not implemented in all browsers. E.g. this won't work in Firefox. stream.stop() is also deprecated in favor of stream.getTracks().forEach(track => track.stop())
