Hello, We are using HLS for our streaming iOS and tvOS applications. We have DRM protection on our applications but we want add another secure layer which is CDN token. We want to add that CDN token data on header or query parameters. Any of two are applicable at our CDN side. There is a problem at client side. We want to send that token knowledge and refresh at given a time. We add token data using at initial state let asset = AVURLAsset(url: url, options: ["AVURLAssetHTTPHeaderFieldsKey": headers]) and add interceptor with asset.resourceLoader.setDelegate. It works seamlessly. We use AVAssetResourceLoaderDelegate and we can intercept just master playlist and playlists via func resourceLoader(_ resourceLoader: AVAssetResourceLoader, shouldWaitForLoadingOfRequestedResource loadingRequest: AVAssetResourceLoadingRequest) -> Bool and we can refresh CDN token data at only playlists. That token data can be at query params or header. It does not matter. For example, #EXTM3U #EXT-X-VERSION:3 #EXTINF:10.0 https://chunk1?cdntoken=A.ts #EXTINF:10.0 https://chunk2?cdntoken=A.ts #EXTINF:10.0 https://chunk3?cdntoken=A.ts #EXTINF:10.0 assume that it is our .m3u8 file for given live video playlist. It has three chunks with cdn token data in query params. If we give that chunks to AVPlayer. It is going to play chunks in order. When we change new cdn token at query params, it effects our chunk Urls and our player stalls. It is because our cdn adds new cdn token knowledge to chunk's Url. It means that our new .m3u8 is going to be like that for next playlist; #EXT-X-VERSION:3 #EXTINF:10.0 https://chunk4?cdntoken=B.ts #EXTINF:10.0 https://chunk5?cdntoken=B.ts #EXTINF:10.0 https://chunk6?cdntoken=B.ts #EXTINF:10.0 Cdn token data is converted to B from A at cdn side and it sends new playlist like that. That's why, our player is going to stall. Is there any way not to player stall with edited chunk url? When we change new cdn token at header. It does not change chunks url like at the first question but AVPlayer does not allow to intercept chunk Urls which means that before callin https://chunk1?cdntoken=A.ts url, i want to intercept and add new cdn token data to header. Is there any way to intercept chunk Urls like intercepting playlist? Thanks for answers in advance

Problem Description This HLS video https://lf3-vod-cdn-tos.douyinstatic.com/obj/vodsass/hls/main.m3u8 starts with noise at 22 seconds play directly on MacOS 12.6.6 Safari，and it also appears on iOS (16.5.1) safari. But there is no noise when playing with MSE on Mac by the third-party open source web playe such as hls.js on Safari. Test tool hls.js test demo: https://hlsjs.video-dev.org/demo/

Hi I'm developing a full-duplex iPhone voice chat application and I'd like to intercept bluetooth headset button events to perform certain actions in my app while maintaining a full-duplex audio. I'm using the MediaPlay to intercept remote bluetooth AVRCP MPRemoteCommandEvent play/pause events as well setting AVAudioSession to use the BluetoothA2DP category, however, when I do this, I can't seem to use the bluetooth microphone as an audio input. Specifically, when I query AVAudioSession for available inputs, bluetooth is not returned. I'm guessing this is because A2DP is a half-duplex protocol, but my understanding is that AVRCP events are only available with A2DP. The other bluetooth profile choice is HSP (AVAudioSession category Bluetooth), which works for full-duplex audio, but does not appear to provide a way to intercept the various AT commands from this profile unless I'm in an actual telephone call. For example, when I use HSP and press a button on my headset, I see in the logs the AT+CHUP command being sent from the headset to the phone. Two questions: Is there a way to use a bluetooth microphone while using A2DP for output at the same time? If the above can't be done, is there a way to intercept the HSP AT control commands from a headset without being in a telephone call? Thanks.

I'm getting the following error in Xcode and I can't figure out how to fix it. Cannot load underlying module for 'MediaPlayer' I've searched Google and have come across lots of other people with similar issues whereby they're importing something and it's producing this error alongside it. https://stackoverflow.com/questions/76256875/cannot-load-underlying-module-for-scenekit https://developer.apple.com/forums/thread/115059 https://stackoverflow.com/questions/32673866/cocoapods-cannot-load-underlying-module-for-x The error is being shown inline with this bit of code: import SwiftUI import MusicKit import MediaPlayer <-- this line here I can build and run the project without issue and it disappears. But will quickly reappear again a short while later and it's very annoying. How can I resolve this please?

We are using AVPlayerViewController to display/play video. Till iOS 15 video player options are visible but for iOS 16 it's not visible. Do we require to make changes for iOS 16 to display video player options?

I have noticed changes Apple Music made to my library, take in particular a changed album edition that is reflected in how the title is listed. I can see the new title in the Music app in two different devices. On one device MPMediaQuery returns the album with the new title. The other device (an iPad with less memory, in case that matters) is still returning the old edition. Is there anything I can do to make sure the data returned is up to date and matches what is seen in the Music app?

I imported the MediaPlayer framework and used MPMusicPlayerPlayParameters in my SwiftUI project. While the app is launching, If the app is built by Xcode 14.3.1 or a newer version, it instantly crashes on a simulator or on a real device. This problem persists on iOS 16.0 to 16.4. (I haven't tried iOS 15 or below) I also tried to build and run the app with Xcode 15 - beta 4 however it still crashes. Because of this reason, I archive and submit to App Store with Xcode 14.2. (the built made by Xcode 14.2 works perfectly!!) Here is the error message: dyld[17235]: Symbol not found: _$sSo27MPMusicPlayerPlayParametersCSe05MediaB0Mc Referenced from: <77FEF170-9C51-3580-8F8B-2ADD2F1B3FD1> /Users/[UserName]/Library/Developer/CoreSimulator/Devices/72CE26D8-4DD4-4319-B0C7-DE52D6645875/data/Containers/Bundle/Application/C808623F-5372-40F0-907F-E86E12AE6EDD/[AppName].app/[AppName] Expected in: <06F636E1-695C-34F1-809D-7CA24F67AFE9> /Library/Developer/CoreSimulator/Volumes/iOS_20B72/Library/Developer/CoreSimulator/Profiles/Runtimes/iOS 16.1.simruntime/Contents/Resources/RuntimeRoot/System/Library/Frameworks/MediaPlayer.framework/MediaPlayer I believe this is Apple related issue however if there is any way that can fix the issue, please let me know.

If I disable playback controls for an AVPlayer (showsPlaybackControls), some feature of MPNowPlayingInfoCenter no longer working. (play/pause, skip forward and backward). I need custom video and audio controls on my AVPlayer in my app, that's why I disabled the iOS playback controls. But I also need the features of the MPNowPlayingInfoCenter. Is there another solution to achieve this?

Hi Team, I am trying to play audio by using AVPlayer from the background that I have fetch data from api after first content play and start next content taken from api. Firstly I play audio from the foreground state than put my app in background after few minutes first audio completed and I try to initiate AVPlayer using next audio content from background but the audio is not playing. Same audio playing in next mode fine when app is in foreground state.

Hi, I am currently using the third-party audio library to play audio in my app. It's worth noting that my app deals exclusively with network audio, so the audio that is stored on the network. I deal with Shoutcast streams and just remote MP3 files. Is there a way to do this with native APple APIs? My motivation is that I want to adopt Share Play, lock screen player support and other native goodies. I use Swift UI.P.S. Sorry for random tags, I am blind and the interface for choosing tags cannot be used with VoiceOver

As of the latest builds of both iOS 16.6 and iOS 17.0, playing albums from a users library using ApplicationMusicPlayer plays the songs on that album out of order. This is a dealbreaker for my app, and I’ve had to revert back to the Media Player framework for reliable behavior. If I fetch an album from a MusicLibraryRequest and load it into the queue using the API introduced in 16.4, init(album:startingAt:)., it starts at track 1 but then plays the rest of the tracks in random order. This happens whether skipping tracks or letting them play through. The shuffleMode of the player is .off. The issue does not occur with albums fetched from the Apple Music catalog and loaded using that same API, nor does it occur for MPMediaItemCollections loaded into an applicationQueuePlayer via a queue descriptor. I've submitted this issue as FB12495051 and provided a sysdiagnose. Please let me know if I can provide any other information.

hi I am having a issue with sound on a network video stream, the stream is loaded by a m3u,. during playback there is no audio from the device, however when using headphones / airplay audio works correctly. the other peculiar thing is the device simulator works fine. this maybe related to airplay working, but I don't know. this is the view handling the playback. Im not sure where the issue is. I can also play the videos fine when embedding the avplayer in its own view. but that looks messy when you have to dismiss a second window when closing the video. #if os(iOS) import SwiftUI import AVKit import MediaPlayer struct iOSVideoLibraryView: View { @ObservedObject var videoLibrary: VideoLibrary @State private var isPlayerDismissed = false let LiveStreams = [GridItem(.flexible()), GridItem(.flexible()), GridItem(.flexible())] let VODStreams = [GridItem(.flexible()), GridItem(.flexible()), GridItem(.flexible()), GridItem(.flexible())] var body: some View { NavigationView { ScrollView { LazyVGrid(columns: LiveStreams, spacing: 20) { ForEach(videoLibrary.videos, id: \.title) { video in if video.type == "LIVE" { Button(action: { isPlayerDismissed = false // Reset the dismissal flag presentVideoPlayer(videoURL: video.referenceURL) }) { VStack { Image(systemName: "play.circle.fill") .font(.system(size: 30)) // icon .foregroundColor(.blue) Text(video.title) .frame(width: 100, height: 50) // title bounds .font(Font.caption) .background(Color.blue) .foregroundColor(.white) .cornerRadius(3) } .frame(width: 70) // main button container .padding() .background(Color.blue.opacity(0.2)) .cornerRadius(10) } } else { // Handle non-LIVE videos } } } .padding() } .navigationBarTitle("Live Streams") } } private func presentVideoPlayer(videoURL: URL) { let playerViewController = CustomAVPlayerViewController() let player = AVPlayer(url: videoURL) playerViewController.player = player player.isMuted = false player.play() DispatchQueue.main.async { playerViewController.modalPresentationStyle = .fullScreen UIApplication.shared.windows.first?.rootViewController?.present(playerViewController, animated: true, completion: nil) } } } class PlayerManager: NSObject, AVPictureInPictureControllerDelegate { static let shared = PlayerManager() func pictureInPictureControllerWillStartPictureInPicture(_ pictureInPictureController: AVPictureInPictureController) { // Perform any necessary actions when picture-in-picture starts } func pictureInPictureControllerDidStopPictureInPicture(_ pictureInPictureController: AVPictureInPictureController) { // Perform any necessary actions when picture-in-picture stops } func pictureInPictureController(_ pictureInPictureController: AVPictureInPictureController, failedToStartPictureInPictureWithError error: Error) { // Perform any necessary actions when picture-in-picture fails to start } } class CustomAVPlayerViewController: AVPlayerViewController { let playerManager = PlayerManager.shared let customPlayer = AVPlayer() override func viewDidAppear(_ animated: Bool) { super.viewDidAppear(animated) if AVPictureInPictureController.isPictureInPictureSupported() { if let playerItem = customPlayer.currentItem { let playerLayer = AVPlayerLayer(player: customPlayer) playerLayer.videoGravity = .resizeAspectFill let pictureInPictureController = AVPictureInPictureController(playerLayer: playerLayer) pictureInPictureController?.delegate = playerManager if let pictureInPictureController = pictureInPictureController, pictureInPictureController.isPictureInPicturePossible { pictureInPictureController.startPictureInPicture() } } } } override func viewDidLoad() { super.viewDidLoad() customPlayer.addObserver(self, forKeyPath: "currentItem", options: .new, context: nil) } override func viewDidDisappear(_ animated: Bool) { super.viewDidDisappear(animated) customPlayer.removeObserver(self, forKeyPath: "currentItem") } override func observeValue(forKeyPath keyPath: String?, of object: Any?, change: [NSKeyValueChangeKey : Any]?, context: UnsafeMutableRawPointer?) { if keyPath == "currentItem" { if let playerItem = customPlayer.currentItem { // Handle player item change } } } } #endif

Hey there Apple Music team! I'm excited to dig into the sessions coming up this week, and what I've seen so far from the developer documentation diffs looks great: audio quality, artist images, and a way to interface with a user's music library in MusicKit. Love it! The thing at the very top of my WWDC wishlist this year was macOS/Mac Catalyst support for the ApplicationMusicPlayer class. I just got finished installing Ventura and Xcode 14, and sadly it looks like the support story is the same as on Big Sur. No API availability on macOS, and an available Mac Catalyst API that ultimately results in the same error from a feedback I submitted on Big Sur: FB9851840 The connection to service named com.apple.Music.MPMusicPlayerApplicationControllerInternal was invalidated: failed at lookup with error 3 - No such process. Is that the end of the story on Ventura, or is there a chance support might be added in a later beta? Is there any additional detail at all that can be shared? I field several requests a week asking if/when my app is coming to the Mac, and I would really love to be able to make that happen. If there is anything at all I can do to test and help overcome the engineering challenges alluded to in the past, I am ready, willing, and able! In any case, thanks for the great work, and I'm looking forward to spending time with the new stuff this summer.

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!

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 } }

I am simply trying to visualize m3u8 files from my Amazon S3 server while they are playing on my AVPlayer. The basic context of my AVPlayer is that I first create AVURLAsset and attach the cookies required to access it and then subsequently create the AVPlayerItem. I then setup the AVPlayer, play it, and then setup an observer so that I can handle some logic when the audio file is done playing. I just want to be able to get the power data of the streamed file in real time or close to real time. I looked into audioTapProcessor but it does not appear to work with streamed files. I then looked into AVAudioEngine but that also does not work well with streams. Is there any solution to this?

Hello, Here is an issue I encountered recently. Does anybody have feedback on this? Issue encountered AVAudioFile throws when opening WAV files and MPEG-DASH files with .mp3 extension, works fine with many other tested combinations of formats and extension (for example, an AIFF file with .mp3 extension is read by AVAudioFile without error). The Music app, AVAudioFile and ExtAudioFile all fail on the same files. However, previewing an audio file in Finder (select the file and hit the space bar) works regardless of the file extension. Why do I consider this an issue? AVAudioFile seems to rely on extension sometimes but not always to guess the audio format of the file, which leads to unexpected errors. I would expect AVAudioFile to deal properly with wrong extensions for all supported audio formats. ⚠️ This behaviour can cause real trouble in iOS and macOS applications using audio files coming from the user, which often have unreliable extensions. I published some code to easily reproduce the issue: https://github.com/ThomasHezard/AVAudioFileFormatIssue Thank you everybody, have a great day 😎
