Signaling Protocol

The Unity Render Streaming package provides two different signaling protocols as examples.

  • HttpSignaling
  • WebSocketSignaling

In the example, the schema given to URL Signaling is used to determine which protocol to use.

Render Streaming backend

If it starts with http, HttpSignaling is used. If it starts with ws, WebSocketSignaling is used.

HttpSignaling

Signaling is handled by HTTP Request. The signalling server is polled at specified intervals to obtain the Offer and Candidate of the difference from the last time.

WebSocketSignaling

Signaling is handled by WebSocket. When the signaling server receives the Offer or Candidate, the server distributes it to the connected clients.

Warning

WebSocket does not work in iOS Safari on servers that use self-signed certificates. If you want to verify the behavior of WebSocket signaling in iOS Safari, use a certificate issued by a trusted certification authority. Or try signaling with HTTP.
