I'm getting a variety of errors when I call prepareToPlay on the MPMusicPlayerController. Sometimes they happen, sometimes they don't. I'm trying to play songs from the Apple Music service. When I don't get the errors, it plays just fine. I have iOS v13.5.1 on my iPhone Xs and I'm using Xcode 11.5. This is my code: let applicationMusicPlayer = MPMusicPlayerController.applicationMusicPlayer applicationMusicPlayer.setQueue(with: [trackID]) applicationMusicPlayer.prepareToPlay(completionHandler:{ error in if let error = error { print(error.localizedDescription) return } DispatchQueue.main.async{ applicationMusicPlayer.play() } } These are the various errors I'm getting: [SDKPlayback] Failed to prepareToPlay error: Error Domain=MPMusicPlayerControllerErrorDomain Code=2 "Queue was interrupted by another queue" UserInfo={NSDebugDescription=Queue was interrupted by another queue} [SDKPlayback] Failed to prepareToPlay error: Error Domain=MPMusicPlayerControllerErrorDomain Code=9 "Preparing queue timed out" UserInfo={NSDebugDescription=Preparing queue timed out} [SDKPlayback] Failed to prepareToPlay error: Error Domain=MPMusicPlayerControllerErrorDomain Code=6 "Failed to prepare to play" UserInfo={NSDebugDescription=Failed to prepare to play} [SDKPlayback] applicationQueuePlayer _establishConnectionIfNeeded timeout [ping did not pong]

Is there a way to disable the default video controls (play/pause/scrubber/etc) on the new SwiftUI VideoPlayer in iOS14, so I could create a custom one?

Just wondering if anyone else is having issues with currentPlaybackRate in release version of iOS 15.4? In my particular case this is using MPMusicPlayerController.applicationQueuePlayer. I've always had issues controlling this property reliably but from what I can see it is now completely non-operational in 15.4. I've isolated this behavior in a trivial project, and will file a radar, but hoping others may have some insight first. FWIW- This is my trivial test case: class ViewController: UIViewController {     lazy var player: MPMusicPlayerApplicationController = {         let player = MPMusicPlayerController.applicationQueuePlayer         player.repeatMode = .none         player.shuffleMode = .off         player.beginGeneratingPlaybackNotifications()         return player     }()     override func viewDidLoad() {         super.viewDidLoad()         NotificationCenter.default.addObserver(forName: .MPMusicPlayerControllerPlaybackStateDidChange, object: nil, queue: .main) { [weak self] notification in             guard let notificationPlayer = notification.object as? MPMusicPlayerApplicationController,                   notificationPlayer === self?.player else {                 return             }                          debugPrint("Player state now: \(notificationPlayer.playbackState)")         }     }     @IBAction func goAction(_ sender: Any) {         guard let item = MPMediaQuery.songs().items?.randomElement() else {             debugPrint("Unable to access media items")             return         }         debugPrint("Now playing item: \(item.title ?? "")")         player.setQueue(with: [item.playbackStoreID])         player.prepareToPlay() { error in             guard error == nil else {                 debugPrint("Player error: \(error!.localizedDescription)")                 return             }             DispatchQueue.main.async { [weak self] in                 self?.player.play()             }         }     } @IBAction func slowAction(_ sender: Any) {         debugPrint("Setting currentPlaybackRate to 0.5")         player.currentPlaybackRate = 0.5         checkPlaybackRate()     } @IBAction func fastAction(_ sender: Any) {         debugPrint("Setting currentPlaybackRate to 1.5")         player.currentPlaybackRate = 1.5         checkPlaybackRate()     } func checkPlaybackRate(afterSeconds delay: TimeInterval = 1.0) {         DispatchQueue.main.asyncAfter(deadline: .now() + delay) {             debugPrint("After \(delay) seconds currentPlaybackRate now: \(self.player.currentPlaybackRate)")         }     } } Typical console output: "Now playing item: I Know You Know" "Player state now: MPMusicPlaybackState(rawValue: 2)" "Player state now: MPMusicPlaybackState(rawValue: 1)" "Setting currentPlaybackRate to 1.5" "After 1.0 seconds currentPlaybackRate now: 1.0" "Setting currentPlaybackRate to 0.5" "After 1.0 seconds currentPlaybackRate now: 1.0"

Hey there, we're using a CDN with HTTP referer checks in place for streaming media. When streaming with Airplay, what is the referer set on the HTTP header? For instance, for Google Chromecast, it's: https://www.gstatic.com/

We noticed iOS 16 doesn't seem to support these commands anymore: MPRemoteCommandCenter.shared().likeCommand MPRemoteCommandCenter.shared().dislikeCommand MPRemoteCommandCenter.shared().bookmarkCommand Or is there another way to show a menu in lieu of the previous button on the lock screen?

Hi I have this piece of code in my app that is supposed to open up a file from Music(old iTunes) app and play. But I get 'Attempted to register account monitor for types client is not authorized to access "com.apple.account.iTunesStore". Any suggests how to fix this. What entitlements do I need to set? Code and error logs are below code-block ``` func showiPOD() {           let mediaPicker: MPMediaPickerController = MPMediaPickerController.self(mediaTypes:MPMediaType.anyAudio)     mediaPicker.delegate = self as MPMediaPickerControllerDelegate     mediaPicker.allowsPickingMultipleItems = false     mediaPicker.showsCloudItems = true //show from iCloud as well.. needs to be tested     self.present(mediaPicker, animated: true, completion: nil)   } 2023-01-24 09:31:22.018992-0800 Smart Practice[526:16253] [Entitlements] MSVEntitlementUtilities - Process Smart Practice PID[526] - Group: (null) - Entitlement: com.apple.accounts.appleaccount.fullaccess - Entitled: NO - Error: (null) 2023-01-24 09:31:22.022520-0800 Smart Practice[526:16253] [core] Attempted to register account monitor for types client is not authorized to access: {(   "com.apple.account.iTunesStore" )} ```language code-block

I'm developing a media player for Mac (AppKit, not Catalyst) that plays local and remote content. I have AirPlay working with AVPlayer (with an AVRoutePickerView assigning the route), but while I get the metadata that I've set for the MPNowPlayingInfoCenter on the AirPlay device (a TV in this case), I don't get any album art (but I do in the macOS now playing menu bar/control centre applet). It looks like this: (imgur link because I can't get it to upload in the forum): https://i.imgur.com/2JBIYCw.jpg My code for setting the metadata:         NSImage *artwork = [currentTrack coverImage];         CGSize artworkSize = [artwork size];         MPMediaItemArtwork *mpArtwork = [[MPMediaItemArtwork alloc] initWithBoundsSize:artworkSize requestHandler:^NSImage * _Nonnull(CGSize size) {             return artwork;         }];         [songInfo setObject: mpArtwork forKey:MPMediaItemPropertyArtwork]; I noticed that it doesn't resize, but it seems at least macOS doesn't care. I tried modifying the code to resize the artwork in the callback, but that also doesn't change anything. I noticed in the logs that I get a message about a missing entitlement: 2023-01-29 14:00:37.889346-0400 Submariner[42682:9794531] [Entitlements] MSVEntitlementUtilities - Process Submariner PID[42682] - Group: (null) - Entitlement: com.apple.mediaremote.external-artwork-validation - Entitled: NO - Error: (null) ...however, this seems to be a private entitlement and the only reference I can find to it is WebKit. Using it makes LaunchServices very angry at me, and I presume it's a red herring.

Hi, I’m looking at using MusicKit in my watchOS app however I don’t seem to have any method of being able to play the audio though the recommended use of MPMusicPlayerController since it isn’t available on watchOS. This method works fine for iOS and iPadOS but not watchOS which seems bizarre considering we have full access to MusicKit but no way to actually play any audio. I’m trying to build an app that includes Apple Music through MusicKit but don’t have any way to actually play the audio. Is there a technical reason for this and if so is there any other way to play audio from MusicKit on watchOS. The docs for MPMusicPlayerController can be found here: https://developer.apple.com/documentation/mediaplayer/mpmusicplayercontroller

I'm using applicationQueuePlayer in my application. I set Queue for it and it plays music. It was working fine in the app installed on my phone, but after phone was updated to iOS 16.4 it stopped working (see errors below). When I remove app from phone and recompiled and re-installed it to that phone, player started working normally. But when I replaced container via Xcodes Device and Simulators to previously saved - it stopped working again. Re-installing it on top of existing didn't fix it. It was only working if removed from phone completely and then installed from Xcode "from scratched". This started happening after phone update to 16.4. When I installed app "from scratch" - it was working fine, but when 16.4.1 was release couple of days ago and I installed it on a phone, it again broke the applicationQueuePlayer in my app. Same thing - removing app from phone and installing from scratch from Xcode makes it work, but restoring old container via Devices and Simulators breaks it again. I presume it has something to do with entitlements, but can't find any notes or info. Please help!

Using quicktime play mp4 file, an error occurred and the document "XX. mp4" could not be opened. An unknown error occurred (-12842), and with Safari browser, only the first keyframe can be played and the video will become stuck. Both Chrome and Firefox can play [normally]

I have a song playlist whose element is MPMediaItem, and I want to share this song playlist, so my original plan was to use persistentID as the identification of the song, but I found that persistentID does not seem to be able to cross devices, use MPMediaQuery persistentID to query the result is empty. So my question is? In this case, what should I do to share this playlist, so that other users can find the corresponding song to play after getting the playlist.

I'm trying to configure the "Now Playing" information for my app on iOS. Using MPNowPlayingInfoCenter/MPRemoteCommandCenter is pretty straightforward for this. The issue I'm having is that the audio I'm playing is generated "on the fly" and I do not know the exact duration in seconds. I am able to synthesize an NSProgress to display the progress of the playback but the units are not in seconds. So if I use the NSProgress units with MPNowPlayingInfoCenter the "Now Playing" shows the units in seconds but it appears to be jumpy (because again my progress units are not in seconds but an approximation of the percent completed). [playInfo setObject:@(self.progress.totalUnitCount) forKey:MPMediaItemPropertyPlaybackDuration]; [playInfo setObject:@(self.progress.completedUnitCount) forKey:MPNowPlayingInfoPropertyElapsedPlaybackTime]; I see there is a MPNowPlayingInfoPropertyPlaybackProgress which looks like it would be perfect. I tried setting that instead of MPMediaItemPropertyPlaybackDuration/MPNowPlayingInfoPropertyElapsedPlaybackTime but it appears to have no effect in the "Now Playing" UI. I also tried setting MPNowPlayingInfoPropertyIsLiveStream to YES but that just makes the "Now Playing" UI display "Live" instead of the progress value. Is there a way I can show a progress bar without the units being displayed in seconds? Thanks in advance.

I have an idea for an iOS App that involves creating alarms and "undismissable" notifications. Currently, iOS has multiple system features like silent/ring mode, focus mode, security protections, and other system features that would limit the functionality of an app with this purpose. Basically, think of a system Amber Alert or how the iOS Alarm app works. Regardless of these system settings, the user will be notified of the importance of the alarm immediately. What I'm trying to develop are really two separate things. First an alarm app without a snooze (or a set snooze limit) where you must prove that you're awake. Second, integrate a web API service for volunteer first responders that notify them to respond to an emergency via an iOS app. These are not features that would limit a user's privacy, their experience using iOS, and, quite frankly, be something that is so difficult to implement. If anyone can direct me to any system APIs that would be available to use for the start of this app or make me aware of any "blockers" that would absolutely prevent me from developing this in iOS, I would really appreciate it. My research has not been very in depth and there are differences in opinions on approaches and possibilities. If you are an engineer at Apple and this turns out to be impossible or impractical with current versions of iOS, it would be great to have the ability to be able to do something of this nature in the future.

However, control center symbols stays as pause regardless of what I do in the app. Am I missing anything?
