Example 1 with WebRTCSessionDescription

use of im.actor.runtime.webrtc.WebRTCSessionDescription in project actor-platform by actorapp.

the class PeerConnectionActor method onOffer.

    // Ignore if we are not waiting for handshake
    if (state != PeerConnectionState.WAITING_HANDSHAKE) {
        return;

    if (this.sessionId != -1) {
        return;
    }
    //
    // Stages
    // 1. Set Remote Description
    // 2. Create Answer
    // 3. Set Local Description
    // 4. Send Answer
    // 5. Enter READY mode
    //
    isReady = false;
