My swift code below goal is to record a 5 second video automatically and save it to the photo gallery when the code is built. In func fileOut I assume that is where you save the video to the photo gallery. I dont know what to put in fileOutput. But fileOutPut is required in my code to run. I think I have all the code to do this but I might be missing something else.
import AVFoundation;import UIKit
class ViewController: UIViewController, AVCaptureFileOutputRecordingDelegate {
func fileOutput(_ output: AVCaptureFileOutput, didFinishRecordingTo outputFileURL: URL, from connections: [AVCaptureConnection], error: Error?) {
}
var captureSession = AVCaptureSession()
var sessionOutput = AVCaptureStillImageOutput()
var movieOutput = AVCaptureMovieFileOutput()
var previewLayer = AVCaptureVideoPreviewLayer()
@IBOutlet var cameraView: UIView!
override func viewWillAppear(_ animated: Bool) {
self.cameraView = self.view
let devices = AVCaptureDevice.devices(for: AVMediaType.video)
for device in devices {
if device.position == AVCaptureDevice.Position.front{
do{
let input = try AVCaptureDeviceInput(device: device )
if captureSession.canAddInput(input){
captureSession.addInput(input)
sessionOutput.outputSettings = [AVVideoCodecKey : AVVideoCodecType.jpeg]
if captureSession.canAddOutput(sessionOutput){
captureSession.addOutput(sessionOutput)
previewLayer = AVCaptureVideoPreviewLayer(session: captureSession)
previewLayer.videoGravity = AVLayerVideoGravity.resizeAspectFill
previewLayer.connection!.videoOrientation = AVCaptureVideoOrientation.portrait
cameraView.layer.addSublayer(previewLayer)
previewLayer.position = CGPoint(x: self.cameraView.frame.width / 2, y: self.cameraView.frame.height / 2)
previewLayer.bounds = cameraView.frame
}
captureSession.addOutput(movieOutput)
captureSession.startRunning()
let paths = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask)
let documentURL = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).first!
let fileURL = documentURL.appendingPathComponent("tempImage.jpg")
try? FileManager.default.removeItem(at: fileURL)
movieOutput.startRecording(to: fileURL, recordingDelegate: self)
let deadlineTime = DispatchTime.now() + .seconds(1)
DispatchQueue.main.asyncAfter(deadline: deadlineTime) {
print("test")
self.movieOutput.stopRecording()
}
}
}
catch{
print("Error")
}
}
}
}
func captureOutput(captureOutput: AVCaptureFileOutput!, didFinishRecordingToOutputFileAtURL outputFileURL: NSURL!, fromConnections connections: [AnyObject]!, error: NSError!) {
print("FINISHED \(error)")
// save video to camera roll
if error == nil {
UISaveVideoAtPathToSavedPhotosAlbum(outputFileURL.path!, nil, nil, nil)
}
}
}
