AVPlayerViewController has the functionality to keep playing the audio when the app is backgrounded or the device is locked. Obviously picture in picture improves this when the app is backgrounded but we lose the functionality when the device is locked as it stops the audio. The user can hit play on the lock-screen to continue playing but doesn't seem to be ideal. Is there any way around this or is the expected behaviour?

I implemented a custom player and used AVPictureInPictureController. pip button is coming and also calling startPictureInPicture() in action. controller.isPictureInPicturePossible is returning true. AVPictureInPictureController delegates are not receiving the call. Any help? func pictureInPictureControllerWillStartPictureInPicture(_ pictureInPictureController: AVPictureInPictureController) {     print("PIP will start") } Have enabled Picture in picture in background mode capability set AVAudioSession category to playback in appdelegate set AVAudioSession.sharedInstance().setActive(true) as true

Due to legal restrictions I need to prevent my app's users from skipping and fast-forwarding the content that is played by AVPlayerViewController. I use playerViewController(:willResumePlaybackAfterUserNavigatedFrom:to:) and playerViewController(:timeToSeekAfterUserNavigatedFrom:to:) delegate methods to control the skipping behaviour. However, those delegate methods are only triggered for skip +/- 10, but not for fast-forwarding/rewinding.  Is there a way to prevent fast-forwarding in addition to skipping in AVPlayerViewController? Here is an example of the code I use: class ViewController: UIViewController {   override func viewDidAppear(_ animated: Bool) {     super.viewDidAppear(animated)     setUpPlayerViewController()   }   private func setUpPlayerViewController() {     let playerViewController = AVPlayerViewController()     playerViewController.delegate = self guard let url = URL(string: "https://devstreaming-cdn.apple.com/videos/streaming/examples/img_bipbop_adv_example_ts/master.m3u8") else {       debugPrint("URL is not found")       return     }     let playerItem = AVPlayerItem(url: url)     let player = AVPlayer(playerItem: playerItem)     playerViewController.player = player     present(playerViewController, animated: true) {       playerViewController.player?.play()     }   } } extension ViewController: AVPlayerViewControllerDelegate {   public func playerViewController(_ playerViewController: AVPlayerViewController, willResumePlaybackAfterUserNavigatedFrom oldTime: CMTime, to targetTime: CMTime) { // Triggered on skip +/- 10, but not on fast-forwarding/rewinding     print("playerViewController(_:willResumePlaybackAfterUserNavigatedFrom:to:)")   }   public func playerViewController(_ playerViewController: AVPlayerViewController, timeToSeekAfterUserNavigatedFrom oldTime: CMTime, to targetTime: CMTime) -> CMTime {     // Triggered on skip +/- 10, but not on fast-forwarding/rewinding     print("playerViewController(_:timeToSeekAfterUserNavigatedFrom:to:)")     return targetTime   } }

I have a music app that can play in the background, using AVQueuePlayer. I'm in the process of adding support for CloudKit sync of the CoreData store, switching from NSPersistentContainer to NSPersistentCloudKitContainer. The initial sync can be fairly large (10,000+ records), depending on how much the user has used the app. The issue I'm seeing is this: ✅ When the app is in the foreground, CloudKit sync uses a lot of CPU, nearly 100% for a long time (this is expected during the initial sync). ✅ If I AM NOT playing music, when I put the app in the background, CloudKit sync eventually stops syncing until I bring the app to the foreground again (this is also expected). ❌ If I AM playing music, when I put the app in the background, CloudKit never stops syncing, which leads the system to terminate the app after a certain amount of time due to high CPU usage. Is there any way to pause the CloudKit sync when the app is in the background or is there any way to mitigate this?

I know that if you want background audio from AVPlayer you need to detatch your AVPlayer from either your AVPlayerViewController or your AVPlayerLayer in addition to having your AVAudioSession configured correctly. I have that all squared away and background audio is fine until we introduce AVPictureInPictureController or use the PiP behavior baked into AVPlayerViewController. If you want PiP to behave as expected when you put your app into the background by switching to another app or going to the homescreen you can't perform the detachment operation otherwise the PiP display fails. On an iPad if PiP is active and you lock your device you continue to get background audio playback. However on an iPhone if PiP is active and you lock the device the audio pauses. However if PiP is inactive and you lock the device the audio will pause and you have to manually tap play on the lockscreen controls. This is the same between iPad and iPhone devices. My questions are: Is there a way to keep background-audio playback going when PiP is inactive and the device is locked (iPhone and iPad) Is there a way to keep background-audio playback going when PiP is active and the device is locked? (iPhone)

I am trying to support video playback for remote video files in iOS. It works for a regular video, but has a problem with slow motion videos: the slow motion effect is lost. I.e. A slow motion plays back like a regular speed rate video. Here is what I am doing:         AVURLAsset *asset = [AVURLAsset URLAssetWithURL:url options:nil];         [asset.resourceLoader setDelegate:self.urlDelegate                                     queue:[self.urlDelegate getDispatchQueue]];         AVPlayerItem *playerItem = [AVPlayerItem playerItemWithAsset:asset];         AVPlayer *player = [AVPlayer playerWithPlayerItem:playerItem];         AVPlayerViewController *controller = [[AVPlayerViewController alloc] init];         controller.player = player;         [player play];         [self presentViewController:controller animated:false completion:^{ <snipped>         }]; Note, the url points to a QuickTime (.MOV) video file on a HTTP(s) server. Again, the above code plays a slow motion video just like a regular video without any slow motions. Is it because AVURLAsset does not support slow motion video? What are I missing to let AVPlayer plays slow motion? I am targeting iOS 12 and above. Thanks!

We have QR-scanner feature implemented on web view (WKWebView). If it's dark we want to light our QR-code using flashlight in iPhone. In general, this feature works, but without flashlight. But have that problems: If we turn on torch then camera preview disappears. If turn off torch then camera preview appears. Do you have any idea why it's so? And how can we sort it out? Thanks

Hi I've made an AVplayer() but when I build it for some reason I press play and then the video player crashes and the debugger says "Hit maximum timestamp count, will start dropping events" do you have any fix for this?

AVPlayer was working on a previous version of XCode, but when XCode updated yesterday, the AVPlayer stopped working in the simulator. Here is the error message: [connection] nw_connection_add_timestamp_locked_on_nw_queue [C2] Hit maximum timestamp count, will start dropping events

Is it still possible to tutor a QuickTime movie with hyperlinks? I'm building a website and I know at one point you could author a QuickTime movie that supported links inside the video - either to other timestamps in the video or to other web pages. I don't want to use a custom player, I'd prefer to use the system level. I've seen a really amazing example of this on the mobile version of the memory alpha (Star Trek nerds!) website. There is a movie that plays at the top of pages that is fully interactive. Is that still supported? Is it possible to author that way? I'm not making anything insanely complicate, I just thought it would be a nice way to build a website with tools I'm more comfortable working in.

Hi, In my SwiftUI app, I'm using AVPlayer and a UIViewRepresentable view to play back a video from a network server. There are many videos on the server, so I have a LazyHStack for the video thumbnails. Only one video is shown on screen at a time. When the user scrolls between videos, I will create a new AVPlayerItem and replace the current player item in the AVPlayer. The problem is: the first video plays back without any problems. But when the user scrolls over to the next video, the new video would play for 1 second and then freezes while the audio track continues. The video track would resume after a few seconds. One note is that if I drag the video view a bit without fully scrolling to another video, the video track will resume after I released the drag. So it seems maybe somehow the AVPlayerLayer was not rendering? Related code pieces: struct PlayerView: UIViewRepresentable { let player: Player let width: CGFloat let height: CGFloat @Binding var updateCount: Int func makeUIView(context: Context) -> UIView { print("\(#function)") let playerLayer = AVPlayerLayer(player: player) let view = UIView() view.frame = CGRectMake(0, 0, width, height) playerLayer.frame = view.bounds view.layer.addSublayer(playerLayer) return view } func updateUIView(_ uiView: UIView, context: Context) { print("\(#function)") guard let playerLayer = uiView.layer.sublayers?.first as? AVPlayerLayer else { return } uiView.frame = CGRectMake(0, 0, width, height) if updateCount > 0 { playerLayer.player = player playerLayer.frame = uiView.bounds } } } updateCount was added to force updateUIView called when the parent View increases the updateCount. But it seems not helping much. My question: Is there any known issue about replacing the current item in AVPlayer in SwiftUI app? Here is my code of replacing the current item: let asset = AVURLAsset(url: url) asset.resourceLoader.setDelegate(urlDelegate, queue: urlDelegate.resourceLoaderQueue) let assetKeys = ["playable", "hasProtectedContent"] let playerItem = AVPlayerItem(asset: asset, automaticallyLoadedAssetKeys: assetKeys) player.replaceCurrentItem(with: playerItem) Note that I have a custom delegate to handle the resource loader for the URLAsset. This delegate is the same for all videos. They always plays well when selected first time (i.e. without replacing another video). One more data point: I have an ObjC version of the same design, and it worked without problems.

I am learning SwiftUI, I want to observe an AVPlayer status so I know when the videos is paused or not. My current approach is more less like this: I have VideosView that holds a list of a videos (in ZStack cards). VideoViews has a VideosViewModel. in VideosView i am calling in onAppear VideosViewModel.getItems... struct ItemModel: Identifiable, Codable, Hashable, Equatable { var id: String var author: String // video owner var url: URL? // url to the video var player: AVPlayer? // AVPlayer created based on self.url... mutating func setPlayer(_ avPlayer: AVPlayer) { self.player = avPlayer } } // vm class FeedViewModel: ObservableObject { @Published private(set) var items: [ItemModel] = [] func getItems() async { do { // fetch data from the API let data = try await dataService.fetchFeeds() // download and attach videos downloadFeedVideos(data) } catch { // .... } } private func downloadFeedVideos(_ feeds: [ItemModel]) { for index in feeds.indices { var item = feeds[index] if let videoURL = item.url { self.downloadQueue.queueDownloadIfFileNotExists( videoURL, DownloadOperation( session: URLSession.shared, downloadTaskURL: videoURL, completionHandler: { [weak self] (localURL, response, error) in guard let tempUrl = localURL else { return } let saveResult = self?.fileManagerService.saveInTemp(tempUrl, fileName: videoURL.lastPathComponent) switch saveResult { case .success(let savedURL): DispatchQueue.main.async { // maybe this is a wrong place to have it? item.setPlayer(AVPlayer(url: savedURL)) self?.items.append(item) if self?.items.count ?? 0 > 1 { // once first video is downloaded, use all device cores to fetch next videos // all newest iOS devices has 6 cores self?.downloadQueue.setMaxConcurrentOperationCount(.max) } } case .none: break case .failure(_): EventTracking().track("Video download fail", [ "id": item.id, "ulr": videoURL.absoluteString.decodeURL() ]) } }), { fileCacheURL in // file already downloaded DispatchQueue.main.async { item.setPlayer(AVPlayer(url: fileCacheURL)) self.items.append(item) } }) } } } } I found this article with some pseudo-code of how to track video playback state but I'm not sure how to implement it in my code.... https://developer.apple.com/documentation/avfoundation/media_playback/observing_playback_state

I want to use AVPlayerViewController to display the video but it should be in auto-play mode. Previously I was using AVPlayer for that and listening to the .AVPlayerItemDidPlayToEndTime notification but I wonder if there is a better way? eg. using AVPlayerLooper for instance so I don't have to use that .AVPlayerItemDidPlayToEndTime anymore I wrote something like this but it is not working - I have a black screen with video controls - probably because AVPlayerViewController does not have any playable content... struct VideoPlayerQueuedView: UIViewControllerRepresentable { let videoUrl: URL func makeUIViewController(context: Context) -> AVPlayerViewController { let queuePlayer = AVQueuePlayer() let playerViewController = AVPlayerViewController() // Create an AVPlayerItem from the videoUrl let playerItem = AVPlayerItem(url: videoUrl) // Create an AVPlayerLooper with the queuePlayer and the playerItem as the template item let playerLooper = AVPlayerLooper(player: queuePlayer, templateItem: playerItem) // Set the player property of AVPlayerViewController playerViewController.player = queuePlayer return playerViewController } func updateUIViewController(_ uiViewController: AVPlayerViewController, context: Context) { // Update the video player if needed } }

Can we use picture in picture for non-video application?
