Getting crash when ice candidate delegate method called
Please help what is the issue.???
webrtc library calling some internal method and getting excess_bad. and crashed
If needed any more information plz ask.
//code
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)
I am getting sip here.
public func peerConnection(_ peerConnection: RTCPeerConnection!, didCreateSessionDescription sdp: RTCSessionDescription!, error: Error!)
getting crash when this delegate called.
func peerConnection(_ peerConnection: RTCPeerConnection!, gotICECandidate candidate: RTCICECandidate!)

Please check your iceServer is Running fine or not, I have used Following iceServers and resolved the crash. Or you can build your own STUN server . It may be one of reason you are getting the crash.
let iceServer1:RTCICEServer = RTCICEServer.init(uri: URL.init(string: "stun:stun.l.google.com:19302"), username: "", password: "")
OR
let iceServer2:RTCICEServer = RTCICEServer.init(uri: URL.init(string: "turn:numb.viagenie.ca"), username: "webrtc@live.com", password: "muazkh")
