Class HTTPConnector

Use HTTPConnector to negotiate a new RTCPeerConnection connection with the server using WHIP (WebRTC HTTP Ingest Protocol) or WHEP (WebRTC HTTP Egress Protocol).

Example

// Listener channel (no initial 'stream' parameter), listen to a stream without sending data
const connection = new HTTPConnector({endPoint, streamName});
// we get the media stream from server
connection.onOpen = stream => videoElement.srcObject = stream;

// Streamer channel (with initial 'stream' parameter), sends and receives media streams
const connection = new HTTPConnector({endPoint, streamName}, {stream: await navigator.mediaDevices.getUserMedia()});
// the media stream here is our local camera as passed in the above constructor
connection.onOpen = stream => {}
