We also faced the issue, any update recently ?

Hello, We tried the method in the demo, it works. I just list our code used before, could you help check this is a iOS or Xcode compatibility issue or we used wrong method. before we just used following api to make it work: {   if (@available(iOS 13.0, *)) {     if ([self.mu_captureSession canAddInput:self.front_deviceInput]) {       [self.mu_captureSession addInput:self.front_deviceInput];     }     if ([self.mu_captureSession canAddOutput:self.front_videoDataOutput]) {       [self.mu_captureSession addOutput:self.front_videoDataOutput];     }     if ([self.mu_captureSession canAddInput:self.back_deviceInput]) {       [self.mu_captureSession addInput:self.back_deviceInput];     }     if ([self.mu_captureSession canAddOutput:self.back_videoDataOutput]) {       [self.mu_captureSession addOutput:self.back_videoDataOutput];     }   } } Now on xcode 14 with iOS 16, we need use extra API AVCaptureInputPort & addConnection API to make it work (like demo code) - (void)initCaptureSession { if (@available(iOS 13.0, *)) { if ([self.mu_captureSession canAddInput:self.front_deviceInput]) { [self.mu_captureSession addInput:self.front_deviceInput]; } if ([self.mu_captureSession canAddOutput:self.front_videoDataOutput]) { [self.mu_captureSession addOutput:self.front_videoDataOutput]; } if ([self.mu_captureSession canAddInput:self.back_deviceInput]) { [self.mu_captureSession addInputWithNoConnections:self.back_deviceInput]; } if ([self.mu_captureSession canAddOutput:self.back_videoDataOutput]) { [self.mu_captureSession addOutputWithNoConnections:self.back_videoDataOutput]; AVCaptureInputPort * backCameraVideoPort = [self.back_deviceInput portsWithMediaType:AVMediaTypeVideo sourceDeviceType:self.back_device.deviceType sourceDevicePosition:self.back_device.position].firstObject; AVCaptureConnection *backCameraVideoDataOutputConnection = [AVCaptureConnection connectionWithInputPorts:@[backCameraVideoPort] output:self.back_videoDataOutput]; if([self.mu_captureSession canAddConnection:backCameraVideoDataOutputConnection]){ [self.mu_captureSession addConnection:backCameraVideoDataOutputConnection]; } } } }

The issue is already fixed by apple.

We also have same issue.
