I am trying to emulate the functionality in Snapchat that lets the user switch cameras while video recording is in progress.
When I remove the capture session's old input and add a new one my AVCaptureMovieFileOutput instance automatically stops recording.
How does Snapchat accomplish this?
My camera switching code is pretty ordinary but here it is nevertheless:
do{
self.camera = getCamera(position: (self.front ? AVCaptureDevicePosition.back : AVCaptureDevicePosition.front))
self.input = try AVCaptureDeviceInput.init(device: self.camera)
}
catch{
...
}
captureSession?.beginConfiguration()
captureSession?.removeInput(captureSession?.inputs[0] as! AVCaptureInput!)
captureSession?.addInput(self.input)
captureSession?.commitConfiguration()
The only answers I could find on Stack Overflow were regarding switching the cameras, but none addressed the fact that the recording stopped.
