冰候选人委托方法调用时崩溃

Question

webrtc库调用某个内部方法并获取多余的\u错误。然后坠毁了

如果需要更多信息，请询问。

//代码

 let iceServer = RTCICEServer(uri:URL(string: resturi), username: “***”, password: “***”)

// Enable SSL globally for WebRTC in our app
let pcFactory:RTCPeerConnectionFactory = RTCPeerConnectionFactory()

let rtcConfiguration = RTCConfiguration()
rtcConfiguration.iceServers = [iceServer!]

let pair1 = RTCPair(key: "OfferToReceiveAudio", value: "true")
let pair2 = RTCPair(key: "OfferToReceiveVideo", value: "false")

let pair3 = RTCPair(key: "DtlsSrtpKeyAgreement", value: "true")

self.mediaConstraints = RTCMediaConstraints(mandatoryConstraints: [pair1!,pair2!], optionalConstraints:[pair3!])

 // Create the peer connection using the ICE server list and the current class as the delegate

    let localStream:RTCMediaStream = pcFactory.mediaStream(withLabel: “12345”)
    let audioTrack:RTCAudioTrack = pcFactory.audioTrack(withID: “123456”)
    audioTrack.delegate = self

    let status = localStream.addAudioTrack(audioTrack)

 self.peerConnection = pcFactory.peerConnection(with: rtcConfiguration, constraints: self.mediaConstraints!, delegate: self)

  let pstatus = self.peerConnection!.add(localStream)

  print(status)
  print(pstatus)

//Let’s look at how the offer is created, which initiates the call.
 self.peerConnection!.createOffer(with: self, constraints: self.mediaConstraints)

我在这里喝了一口。

public func peerConnection(_ peerConnection: RTCPeerConnection!, didCreateSessionDescription sdp: RTCSessionDescription!, error: Error!)

此代理调用时发生崩溃。

func peerConnection(_ peerConnection: RTCPeerConnection!, gotICECandidate candidate: RTCICECandidate!)

Answer 1

请检查您的iceServer是否正常运行，我使用了以下iceServer并解决了崩溃问题。或者您可以构建自己的STUN服务器。这可能是你撞车的原因之一。

let iceServer1:RTCICEServer = RTCICEServer.init(uri: URL.init(string: "stun:stun.l.google.com:19302"), username: "", password: "")

或者

let iceServer2:RTCICEServer = RTCICEServer.init(uri: URL.init(string: "turn:numb.viagenie.ca"), username: "[e-mail]", password: "muazkh")
