Easily Play/Pause videos in any UIView subclass especially UITableViewCell subclass

AutoVideoPlayer

Play/pause videos automatically in UITableview when an UITableViewCell is in focus, videos can be easily embedded in any UITableViewCell subclass. Can be easily extended to support UICollectionView

• Easily implement video player in any UITableView subclass
• Automatic video play when video view is visible and option to easily pause/play any video
• Mute/Unmute videos
• Videos are cached in memory and will be removed when there is memory pressure
• The scroll of UITableView is super smooth since video assets are downloaded on background thread and played only when assets are completely downloaded ensuring the main thead is never blocked
• Option to provide different bit rate for videos
• Works when the app comes again from background

It can also be used to play videos in any subclass of UIView.

Usage

Adopt ASAutoPlayVideoLayerContainer protocol in your UITableviewCell subclass like below.

var videoLayer: AVPlayerLayer = AVPlayerLayer()
    
var videoURL: String? {
    didSet {
        if let videoURL = videoURL {
            ASVideoPlayerController.sharedVideoPlayer.setupVideoFor(url: videoURL)
        }
        videoLayer.isHidden = videoURL == nil
    }
}

Implement following method to return the visible height of the UITableViewCell

func visibleVideoHeight() -> CGFloat {
  //return visible height of the Video Player layer
}

ViewController Code

Put following code in viewDidLoad

NotificationCenter.default.addObserver(self,
                                       selector: #selector(self.appEnteredFromBackground),
                                       name: NSNotification.Name.UIApplicationWillEnterForeground, object: nil)

Add following code to play/pause when view appears/disappears

override func viewDidAppear(_ animated: Bool) {
    super.viewDidAppear(animated)
    pausePlayeVideos()
}

Add following methods

@objc func appEnteredFromBackground() {
    ASVideoPlayerController.sharedVideoPlayer.pausePlayeVideosFor(tableView: tableView, appEnteredFromBackground: true)
}

func pausePlayeVideos(){
    ASVideoPlayerController.sharedVideoPlayer.pausePlayeVideosFor(tableView: tableView)
}

Add following code in UITableView delegate and datasource methods

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    //if cell adopts ASAutoPlayVideoLayerContainer protocol then
    //set videoURL if you want to show video or else nil
}

func tableView(_ tableView: UITableView, didEndDisplaying cell: UITableViewCell, forRowAt indexPath: IndexPath) {
    if let videoCell = cell as? ASAutoPlayVideoLayerContainer, videoCell.videoURL != nil {
        ASVideoPlayerController.sharedVideoPlayer.removeLayerFor(cell: videoCell)
    }
}

Add following code to pause/play videos when scroll stops

func scrollViewDidEndDragging(_ scrollView: UIScrollView, willDecelerate decelerate: Bool) {
    if !decelerate {
        pausePlayeVideos()
    }
}
func scrollViewDidEndDecelerating(_ scrollView: UIScrollView) {
    pausePlayeVideos()
}
