How to playback recorded video? - swift

Question

This is an example of the type of video file i'm trying to play:
file:///private/var/mobile/Containers/Data/Application/7725BCCA-B709-48FB-8FE3-DBC9F4B679C0/tmp/9AD6A48E-6A25-4114-88D3-474A0E1C762F.mp4
I think it's recording but when I try to play the recorded video it's just a blank screen.
func startRecording() {
print("start")
if movieOutput.isRecording == false {
let connection = movieOutput.connection(withMediaType: AVMediaTypeVideo)
if (connection?.isVideoOrientationSupported)! {
connection?.videoOrientation = currentVideoOrientation()
}
if (connection?.isVideoStabilizationSupported)! {
connection?.preferredVideoStabilizationMode = AVCaptureVideoStabilizationMode.auto
}
print(AVCaptureDevice.authorizationStatus(forMediaType: AVMediaTypeVideo))
let device = activeInput.device
if (device?.isSmoothAutoFocusSupported)! {
do {
try device?.lockForConfiguration()
device?.isSmoothAutoFocusEnabled = false
device?.unlockForConfiguration()
} catch {
print("Error setting configuration: \(error)")
}
}
outputURL = tempURL()
movieOutput.startRecording(toOutputFileURL: outputURL, recordingDelegate: self)
} else {
print("stop")
stopRecording()
}
}
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
if segue.identifier == "showPreview" {
let previewVC = segue.destination as! ProfilePhotoPreviewViewController
previewVC.image = self.image
} else if segue.identifier == "showVideoPreview" {
let vc = segue.destination as! ProfilePhotoPreviewViewController
vc.videoURL = videoRecorded
}
}
}
extension TakePhotoViewController: AVCaptureFileOutputRecordingDelegate {
func capture(_ captureOutput: AVCaptureFileOutput!, didStartRecordingToOutputFileAt fileURL: URL!, fromConnections connections: [Any]!) {
}
func capture(_ captureOutput: AVCaptureFileOutput!, didFinishRecordingToOutputFileAt outputFileURL: URL!, fromConnections connections: [Any]!, error: Error!) {
if (error != nil) {
print("Error recording movie: \(error!.localizedDescription)")
} else {
videoRecorded = outputURL! as URL
print(videoRecorded)
print("recorded")
performSegue(withIdentifier: "showVideoPreview", sender: nil)
}
}
}

This code works right here, I had the same problem as you. And I had to add the "mov" file path extension at the end of my file path. See below:
func recordVideo() {
let recordingDelegate: AVCaptureFileOutputRecordingDelegate! = self
let videoFileOutput = AVCaptureMovieFileOutput()
videoOutput = videoFileOutput
self.captureSession.addOutput(videoFileOutput)
let documentsURL = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask)[0]
let filePath = documentsURL.appendingPathComponent("introVideo").appendingPathExtension("mov")
videoFileOutput.startRecording(toOutputFileURL: filePath, recordingDelegate: recordingDelegate)
}
And then I took that url and passed it to my VideoPlayerController as so:
func capture(_ captureOutput: AVCaptureFileOutput!, didFinishRecordingToOutputFileAt outputFileURL: URL!, fromConnections connections: [Any]!, error: Error!) {
if error == nil {
let videoVC = PlayVideoController()
videoVC.url = outputFileURL!
self.navigationController?.pushViewController(videoVC, animated: true)
}
return
}
and then here is my code on VideoPlayerController to play the video that was just recorded:
class PlayVideoController: UIViewController {
var url: URL!
var player: AVPlayer!
var avPlayerLayer: AVPlayerLayer!
override func viewWillAppear(_ animated: Bool) {
if url != nil {
print(url)
player = AVPlayer(url: url)
let playerLayer = AVPlayerLayer(player: player)
self.view.layer.addSublayer(playerLayer)
playerLayer.frame = self.view.frame
player.play()
}
}
}
Hope this helps!
