Is WebRTC available in the Console versions of the Unity SDK? If so, which consoles are supported? (PS4/5, XBOne, Switch, etc). Thanks.
Unless I missed something WebRTC is an external library that has nothing to do with Unity by itself. Whether it works on consoles is something you can research independently of Unity. If anything the console vendors or tech will either allow it or not. If they promote their own video streaming service you may be legally forced to use their tech.
