video imagePickerController cancel not working - swift

Question

I am using custom CropViewController open source imagePicker for photos, and for video I'm trying to use default imagePicker provided by Swift itself since CropViewController doesn't have video option.
After I pick a video from photo library, three buttons shown at the bottom (cancel, play, select). Play button and select button works perfectly but cancel won't work.
Here is my code to trigger imagePickerController for both photo and video.
#objc func videoPresentPicker() {
let picker = UIImagePickerController()
picker.delegate = self
picker.sourceType = .photoLibrary
picker.mediaTypes = [kUTTypeMovie as String]
picker.allowsEditing = true
self.present(picker, animated: true, completion: nil)
}
#objc func photoPresentPicker() {
self.croppingStyle = .default
let picker = UIImagePickerController()
picker.delegate = self
picker.sourceType = .photoLibrary
picker.allowsEditing = false
self.present(picker, animated: true, completion: nil)
}
I am truly appreciated for you help. I have been struggling for few days and finally reaching out for some helps...
Update
extension ChatViewController: CropViewControllerDelegate, UIImagePickerControllerDelegate, UINavigationControllerDelegate {
internal func imagePickerControllerDidCancel(_ picker: UIImagePickerController) {
dismiss(animated: true, completion: nil)
}
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
if let videoUrl = info[UIImagePickerController.InfoKey.mediaURL] as? NSURL {
let data = NSData(contentsOf: videoUrl as URL)!
print("File size before compression: \(Double(data.length / 1048576)) mb")
let compressedURL = NSURL.fileURL(withPath: NSTemporaryDirectory() + NSUUID().uuidString + ".m4v")
self.compressVideo(inputURL: videoUrl as URL, outputURL: compressedURL) { (exportSession) in
guard let session = exportSession else {
return
}
switch session.status {
case .unknown:
break
case .waiting:
break
case .exporting:
break
case .completed:
guard let compressedData = NSData(contentsOf: compressedURL) else {
return
}
print("File size after compression: \(Double(compressedData.length / 1048576)) mb")
case .failed:
break
case .cancelled:
break
#unknown default:
break
}
}
} else {
guard let image = (info[UIImagePickerController.InfoKey.originalImage] as? UIImage) else { return }
let cropController = CropViewController(croppingStyle: croppingStyle, image: image)
cropController.delegate = self
imageView.image = image
picker.dismiss(animated: true, completion: {
self.present(cropController, animated: true, completion: nil)
if self.inputTextField.isFirstResponder == true {
self.handleKeyboardWillShow()
}
})
}
transparentView.alpha = 0
self.tableView.frame = CGRect(x: 0, y: 0, width: 0, height: 0)
dismiss(animated: true, completion: nil)
}

Just implement this function
func imagePickerControllerDidCancel(_ picker: UIImagePickerController) {
dismiss(animated:true, completion: nil)
}
