Using webrtc_ros for custom signaling server

[sjahanshahi]

I have a nodejs signaling server which is broadcasting the video from one peer to many using socketio in the cloud. I want to change the URI in the Ros_webrtc so that robot broadcast the video via this signaling server. and I want to add custom socket messages to cpp client to adjust handshakes with new events messaging. could anyone point me to where in this repository to configure WebSocket cpp code to achieve this?

thanks in advance!
