Verwenden SimpleWebRTC mit Signalling server zu erreichen Ihr Ziel zu verwenden. Weitere Informationen finden Sie unter main site
Sie benötigen nodejs, um den Signalisierungsserver auszuführen, oder Sie können simplewebrtc signalling server zu Testzwecken verwenden.
Bildschirmsharing funktioniert jedoch nur auf HTTPS.
