カスタムオーディオドライバの作成

Swift

セッションイベントによるオーディオコントロール

最後に、Vonage セッションのデリゲート・メソッドを使用して、着信音を処理します。動画を公開した後 doPublish メソッドが着信音開始のトリガーとなる。自己加入ストリームが接続すると subscriberDidConnectToStream メソッドは着信音を停止します。

extension VonageVideoManager: OTPublisherDelegate {
    func publisher(_ publisher: OTPublisherKit, streamCreated stream: OTStream) {
        print("Publishing")
        // play the ringtone for 10 seconds , it is fun...
        // doSubscribe method will stop it later
        DispatchQueue.main.asyncAfter(deadline: .now() + 10) {
            self.doSubscribe(stream)
        }
    }
    
    func publisher(_ publisher: OTPublisherKit, streamDestroyed stream: OTStream) {
        print("publisher \(publisher) streamDestroyed \(stream)")
        
        if let subStream = subscriber?.stream, subStream.streamId == stream.streamId {
            cleanupSubscriber()
        }
        
        cleanupPublisher()
    }
    
    func publisher(_ publisher: OTPublisherKit, didFailWithError error: OTError) {
        print("publisher didFailWithError \(error)")
        cleanupPublisher()
    }
}

extension VonageVideoManager: OTSubscriberDelegate {
    
    func subscriberDidConnect(toStream subscriberKit: OTSubscriberKit) {
        print("subscriberDidConnectToStream (\(subscriber?.stream?.connection.connectionId ?? ""))")
        
        // Stop ringtone from playing, as the subscriber will connect shortly
        myAudioDevice?.stopRingtone()
        guard let view = self.subscriber?.view else { return }
        subView = AnyView(Wrap(view))
    }
    
    func subscriber(_ subscriber: OTSubscriberKit, didFailWithError error: OTError) {
        print("Subscriber failed: \(error.localizedDescription)")
    }
}
