my sid is: PAf4205a8d4d746fc491ae7a85f04cd4cc

now I got stuck within 8 minutes.

I have changed my code while connect Twilio with room and capture of video but still same issue please help me out why this happened.

captured time:

` if PlatformUtils.isSimulator {
return
}
let frontCamera = CameraSource.captureDevice(position: .front)
let backCamera = CameraSource.captureDevice(position: .back)
localAudioTrack = LocalAudioTrack()

    if (frontCamera != nil || backCamera != nil) {
        // Preview our local camera track in the local video preview view.
        camera = CameraSource(options:options,delegate: self)
        
        if let camera = camera {
            localVideoTrack = LocalVideoTrack(source: camera, enabled: true, name: "Camera")

                // Discover a simulcast format for the front camera
                let format = CaptureDeviceUtils.selectFormatBySize(device: frontCamera!,
                                                                   targetSize: CaptureDeviceUtils.kSimulcastVideoDimensions)

                // Lower the frame rate to reduce CPU load, but still produce 3 temporal layers (f, f/2, f/4)
                format.frameRate = CaptureDeviceUtils.kSimulcastVideoFrameRate

                // Apply slight cropping to reduce CPU load, and provide square-ish video
                let croppedFormat = VideoFormat.init()
                croppedFormat.dimensions = CaptureDeviceUtils.kSimulcastVideoDimensions
                camera.requestOutputFormat(croppedFormat)
            localVideoTrack!.addRenderer(localView)
            if (frontCamera != nil && backCamera != nil) {
                // We will flip camera on tap.
                let tap = UITapGestureRecognizer(target: self, action: #selector(VideoCallViewController.getFlipLocalView(gesture:)))
                localView.addGestureRecognizer(tap)
            }
            
            camera.startCapture(device: frontCamera != nil ? frontCamera! : backCamera!) { (captureDevice, videoFormat, error) in
                if let error = error {
                    
                    
                } else {
                    
                    localView.shouldMirror = (captureDevice.position == .front)
                }
            }
        }`

Twilio connect with room:

`func doConnectTwilio(twilioToken: String){
prepareLocalMedia()
let connectionOption = ConnectOptions.init(token: twilioToken) { builder in

      // builder.preferredVideoCodecs =   [TVIVideoCodec.H264.rawValue]
        //new added code
        
        if let audioTrack = self.localAudioTrack {
            builder.audioTracks = [audioTrack]
        }
        if let videoTrack = self.localVideoTrack {
            builder.videoTracks = [videoTrack]
        }
        builder.isNetworkQualityEnabled = true
        builder.isDominantSpeakerEnabled = true
        builder.roomName = self.roomID
        
        builder.networkQualityConfiguration =
        NetworkQualityConfiguration(localVerbosity: .minimal, remoteVerbosity: .minimal)
      builder.encodingParameters = EncodingParameters(audioBitrate:16, videoBitrate:1800)
        builder.preferredVideoCodecs = [Vp8Codec(simulcast: true)]
    }
    self.room = TwilioVideoSDK.connect(options: connectionOption, delegate: self)
    
}`
