Code Revised based on suggestion solution but still not working. Videos are uploading as 0 bytes. I have an app where a user should be able to record a video from their phone and when 'Use Video' is selected it uploads the video to our PHP Server. The file is uploading successfully and based on the size shown it is not empty. However when I go to play the video in the app or even directly through the browser it won't play. There's no issue with the playback code as I've hardcoded links to other videos on other sites and it works fine. Code is below, any help is much appreciated.
// Finished recording a video
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
print("Got a video")
if let pickedVideo:URL = (info[UIImagePickerControllerMediaURL] as? URL) {
// Save video to the main photo album
let selectorToCall = #selector(CameraVideoViewController.videoWasSavedSuccessfully(_:didFinishSavingWithError:context:))
UISaveVideoAtPathToSavedPhotosAlbum(pickedVideo.relativePath, self, selectorToCall, nil)
imageSelected = true
uuid = UUID().uuidString
if imageSelected == true {
saveFileName = "video-\(uuid).mp4"
}
// Save the video to the app directory so we can play it later
let videoData = try? Data(contentsOf: pickedVideo)
let paths = NSSearchPathForDirectoriesInDomains(
FileManager.SearchPathDirectory.documentDirectory, FileManager.SearchPathDomainMask.userDomainMask, true)
let documentsDirectory: URL = URL(fileURLWithPath: paths[0])
let dataPath = documentsDirectory.appendingPathComponent(saveFileName)
try! videoData?.write(to: dataPath, options: [])
print("Saved to " + dataPath.absoluteString)
imagePicker.dismiss(animated: true, completion: {
// Anything you want to happen when the user saves an video
self.encodeVideo(dataPath: dataPath)
self.uploadVideo(videoData!)
})
} }
// MP4 Conversion of video
