GPUImageMovie: how to show the first frame of the video after playback is completed?

Here's how I'm setting the playback:

movie = GPUImageMovie(url: url)
movie.playAtActualSpeed = true
movie.delegate = self
movie.addTarget(self)
movie.startProcessing()

After the playback is completed, GPUImageView shows the last frame of the video file. How to change it to the first frame?

We can use AVPlayerItem and let AVPlayer to handle playback for us:

func configure(url: URL) {
    // player is AVPlayer instance declated as property
    let playerItem = AVPlayerItem(url: url)
    player.replaceCurrentItem(with: playerItem)
    NotificationCenter.default.addObserver(self, selector: #selector(playerDidFinishPlaying(_:)), name: NSNotification.Name.AVPlayerItemDidPlayToEndTime, object: playerItem)

    movie = GPUImageMovie(playerItem: playerItem)
    movie.playAtActualSpeed = true
    movie.addTarget(self)
    movie.startProcessing()
}

func playerDidFinishPlaying(_ notification: Notification) {
    guard player.currentItem == notification.object as? AVPlayerItem else { return }
    player.seek(to: kCMTimeZero)
}
