Please use getDisplayMedia instead

getScreenStream(function(screenStream) {
    video.srcObject = screenStream;
});

function getScreenStream(callback) {
    if (navigator.getDisplayMedia) {
        navigator.getDisplayMedia({
            video: true
        }).then(screenStream => {
            callback(screenStream);
        });
    } else if (navigator.mediaDevices.getDisplayMedia) {
        navigator.mediaDevices.getDisplayMedia({
            video: true
        }).then(screenStream => {
            callback(screenStream);
        });
    } else {
        getScreenId(function(error, sourceId, screen_constraints) {
            navigator.mediaDevices.getUserMedia(screen_constraints).then(function(screenStream) {
                callback(screenStream);
            });
        });
    }
