From Local Path

VideoEditor SDK supports loading video files from the local file system such as the documents or a temporary folder, as well as the app bundle.

Retrieve bundle URL#

First we need to retrieve the URL for a file on the local system. In this example, a file within the app bundle.

Initialize the editor#

We then create a Video from this URL and pass it as videoAsset to the VideoEditViewController to instantiate the video editor. Setting the current class as the delegate of the VideoEditViewController allows us to implement export, cancellation and error handling there.


import UIKit
import VideoEditorSDK

class OpenVideoFromAppBundleSwift: Example, VideoEditViewControllerDelegate {
  override func invokeExample() {
    // Get the URL for a file on the local file system. This could be any file within the app bundle
    // or also a file within the documents or temporary folders for example. This example will use
    // a file from the app bundle.
    guard let url = Bundle.main.url(forResource: "Skater", withExtension: "mp4") else {
      fatalError("Unable to create URL for specified file.")
    }

    // Create a `Video` from the video URL.
    let video = Video(url: url)

    // Create a video editor and pass it the video. Make this class the delegate of it to handle export and cancelation.
    let videoEditViewController = VideoEditViewController(videoAsset: video)
    videoEditViewController.delegate = self

    // Present the video editor.
    videoEditViewController.modalPresentationStyle = .fullScreen
    presentingViewController?.present(videoEditViewController, animated: true, completion: nil)
  }

  // MARK: - VideoEditViewControllerDelegate

  func videoEditViewControllerShouldStart(_ videoEditViewController: VideoEditViewController, task: VideoEditorTask) -> Bool {
    // Implementing this method is optional. You can perform additional validation and interrupt the process by returning `false`.
    true
  }

  func videoEditViewControllerDidFinish(_ videoEditViewController: VideoEditViewController, result: VideoEditorResult) {
    // The user exported a new video successfully and the newly generated video is located at `result.output.url`. Dismissing the editor.
    presentingViewController?.dismiss(animated: true, completion: nil)
  }

  func videoEditViewControllerDidFail(_ videoEditViewController: VideoEditViewController, error: VideoEditorError) {
    // There was an error generating the video.
    print(error.localizedDescription)
    // Dismissing the editor.
    presentingViewController?.dismiss(animated: true, completion: nil)
  }

  func videoEditViewControllerDidCancel(_ videoEditViewController: VideoEditViewController) {
    // The user tapped on the cancel button within the editor. Dismissing the editor.
    presentingViewController?.dismiss(animated: true, completion: nil)
  }
}
