 //video
        self.session = AVCaptureSession()
        guard
            let videoDeviceInput = try? AVCaptureDeviceInput(device: device!),
            self.session!.canAddInput(videoDeviceInput)
            else { return }
        self.session!.addInput(videoDeviceInput)

  //audio
        guard
            let audioDeviceInput = try? AVCaptureDeviceInput(device: mic!),
            self.session!.canAddInput(audioDeviceInput)
            else { return }
        self.session!.addInput(audioDeviceInput)
