Question

我在IOS原生应用中配置了WebRTC，但遇到了一个问题：当我说话时，我听到了自己。我试图关闭所有RTCEAGLVideoView，我仍然听到自己。只有当我评论下一个代码的和平时，我才会听到自己的声音：

            let audioTrack = pcFactory?.audioTrack(withTrackId: "localAudioTrack")
            localStream?.addAudioTrack(audioTrack!)

另外，我尝试过使用audioTrack？.isEnabled = false，它可以工作，但是当我这样做时，对话的对话网站听不到我的声音。

那么，有没有办法在本地静音音轨，但是要让它为远程RTCMediaStream取消静音？谢谢。我的PeerConnection设置如下所示：

     init(peerId:String, sender:RtcDataSender, isPublisher:Bool, isVideo:Bool = true, isAudio:Bool = true) {
        super.init()
        self.audio = isAudio
        self.video = isVideo
        self.rtcDataSender = sender
        self.peerId = peerId
        let decoderFactory = ARDVideoDecoderFactory.init()
        let encoderFactory = ARDVideoEncoderFactory.init()
        rtcDictionaryFactory = RtcDictionaryFactory()
//        pcFactory = RTCPeerConnectionFactory.init(encoderFactory: encoderFactory, decoderFactory: decoderFactory)
        pcFactory = RTCPeerConnectionFactory.init()

        let config = RTCConfiguration.init()
        config.iceServers = servers
        let constraints:[String:String] = ["OfferToReceiveAudio":"\(isAudio)", "OfferToReceiveVideo":"\(isVideo)"]
        let constraintsConnection:[String:String] = ["kRTCMediaConstraintsMinWidth"     : "640",
                                                     "kRTCMediaConstraintsMinHeight"    : "480",
                                                     "kRTCMediaConstraintsMinFrameRate" : "15",
                                                     "kRTCMediaConstraintsMaxWidth"     : "1280",
                                                     "kRTCMediaConstraintsMaxHeight"    : "720",
                                                     "kRTCMediaConstraintsMaxFrameRate" : "30"]
        let mediaConnectionConstraints = RTCMediaConstraints.init(mandatoryConstraints: constraintsConnection, optionalConstraints: nil)
        rtcMediaConstaints = RTCMediaConstraints.init(mandatoryConstraints: constraints, optionalConstraints: nil)
        peerConnection = pcFactory?.peerConnection(with: config, constraints: rtcMediaConstaints!, delegate: self)
        if (isPublisher) {
            localStream = pcFactory?.mediaStream(withStreamId: "localStream")
            if isVideo {
                let track = self.createLocalVideoTrack()
                localStream?.addVideoTrack(track!)
            }
            if isAudio {
                let audioTrack = pcFactory?.audioTrack(withTrackId: "localAudioTrack")
                localStream?.addAudioTrack(audioTrack!)
                audioTrack?.isEnabled = false
//                audioTrack?.isEnabled = false
//                audioTrack?.source.volume = 0
            }
            rtcDataSender?.localStreamAdded(peerId: peerId, stream: localStream!, isVideo: isVideo)
            peerConnection?.add(localStream!)
            if isVideo {
                didCreateCapturer(capturer: capturer!)
            }
        }
    }

WebRTC IOS听到自我音轨回声
