About Signaling Type

The Unity Render Streaming package provides three different signaling types as examples.

  • Http Signaling
  • WebSocket Signaling

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

Render Streaming backend

If it starts with http, Http Signaling is used. If it starts with ws, WebSocket Signaling is used.

# launch server for WebSocket
webserver.exe

# launch server for HTTP
webserver.exe -t http

Http Signaling

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.

WebSocket Signaling

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.
