Hey, try this and let me know if it isn't working. It's working well for me. I did it in different way of course, but it's easier to send it like this.

open func startRecordingVideo() {
    if cameraOutputMode != .stillImage {
        let videoOutput = _getMovieOutput()
        // setup video mirroring
        for connection in videoOutput.connections {
            for port in connection.inputPorts {
                
                if port.mediaType == AVMediaType.video {
                    let videoConnection = connection as AVCaptureConnection
                    if videoConnection.isVideoMirroringSupported {
                        videoConnection.isVideoMirrored = (cameraDevice == CameraDevice.front && shouldFlipFrontCameraImage)
                    }
                }
            }
        }
        
//            let specs = [kCMMetadataFormatDescriptionMetadataSpecificationKey_Identifier as String: AVMetadataIdentifier.quickTimeMetadataLocationISO6709,
//                         kCMMetadataFormatDescriptionMetadataSpecificationKey_DataType as String: kCMMetadataDataType_QuickTimeMetadataLocation_ISO6709 as String] as [String : Any]
//            
//            var locationMetadataDesc: CMFormatDescription?
//            CMMetadataFormatDescriptionCreateWithMetadataSpecifications(kCFAllocatorDefault, kCMMetadataFormatType_Boxed, [specs] as CFArray, &locationMetadataDesc)
//            
//            // Create the metadata input and add it to the session.
//            guard let captureSession = captureSession, let locationMetadata = locationMetadataDesc else {
//                return
//            }
//            
//            let newLocationMetadataInput = AVCaptureMetadataInput(formatDescription: locationMetadata, clock: CMClockGetHostTimeClock())
//            captureSession.addInputWithNoConnections(newLocationMetadataInput)
//            
//            // Connect the location metadata input to the movie file output.
//            let inputPort = newLocationMetadataInput.ports[0]
//            captureSession.add(AVCaptureConnection(inputPorts: [inputPort], output: videoOutput))
        
        _updateIlluminationMode(flashMode)
        
        videoOutput.startRecording(to: _tempFilePath(), recordingDelegate: self)
    } else {
        _show(NSLocalizedString("Capture session output still image", comment:""), message: NSLocalizedString("I can only take pictures", comment:""))
    }
}
