Hello everyone! Im new to this forum and i have a question about playing mp3 files on our Homepage on apple devices: We have a service section with the latest News, Traffic and Weather on our Site. The problem is, that the mp3 Files can be played, but the player shows 0:00 and is not able to go to the middle or end of the file. This is ONLY on Iphone in our app and on Safari. I am recording the mp3 with ffmpeg. The strange thing is, that there is no Bitrate shown in FIle details, and also no length. The File is auto Recorded with a script.

I am trying to get the playbackStoreID via the MPMediaPickerController so I can play songs in my app. For many songs I can see and select I am getting a value of "0" for the playbackStoreID on the returned MPMediaItem. Now if I use the "Music" app I can play those songs, but since the playbackStoreID is "0" I cannot successful get them in the queue for a MPMusicPlayerController.applicationQueuePlayer What's the deal? How do I get a proper ID that I can use to get those songs played? If I cannot, how can I hide those songs from the MPMediaPickerController so a user does not think they can play those songs in my app?

Hi, is there a way to display the animated cover art in an app? Not every album has a cover art but for the ones that have one I would like to display them instead of the artwork. Thank you :)

I have some depth map files in TIFF format that I am trying to extract data from programmatically. I see that I can import TIFF format images with NSImage, and from there, can get the raw pixel data. But how do I convert this to real distances? Any help would be appreciated, thanks!

I have a page that needs to display a large PNG image (1024 x 100247 ) Everything works fine in Chrome and Edge, but failed in safari. this is test image : https://storage-staging.passton.jp/images/2024/03/11/E0R6G8FKd3B3iLPO.png is there any limit in safari ?

Hello! I'm trying to find my own window or SCWindow in a SCDisplay. This is so I can automatically change the SCDisplay to record when I drag a window from a display to another. Is there any way to check the windows that are contained in every SCDisplay? Thank you in advance!

I'm trying to accomplish creating a new playlist on device that appears in AppleMusic, and adding into the playlist a selection of MP3s within a small IOS app. Now the MP3's are either a stream of bytes, or a flat file already stored on the device (the app itself generates these - they aren't downloaded, they are created in app, and then stored on the local device) in it's local storage space. The idea is that created tracks can show up in a specific play list on the device. Now, there appears to be some conflict as to what framework I need to use. I've found MPMediaPlayer, which appears to allow me to create a playlist using the GetPlaylist call, although the documentation on this seems pretty sparse and there's not a lot of examples I can find on how to use this? It looks like a UUID is passed in, but there is no documentation on what this UUID is or where it comes from? If I want to create a new Playlist, I presume I need to generate a UUID, and then store that locally in order to be able to access that playlist again later, yes? There's an AddItem call which looks like it's how you add a track to a playlist, but there's no documentation on how you generate an entry. The documentation for this function talks about a Product ID, without describing what the product ID is, or where it needs to come from. Is this a GUID? Is it a name/description? Does it have to be unique? I'm assuming this Product ID refers to that which is being added to the playlist, but the documentation is sadly lacking in terms of explaining what the product ID refers to. Is it a media Item, or is that what is created when whatever entity the Product ID is referring to is added to the playlist? I'm assuming I can create a NSURL of the file that is stored that is actually the MP3 sample, but what I do with that in order to actually add it as a playlist entry is unknown. I'm sure there is a mechanism to do this, it's just not clear what that is. There's a lack of understanding or explanation of what the process is here, and some illumination would be helpful.

I need to duck the audio coming from ApplicationMusicPlayer while playing a local file using AVAudioPlayer. I've tried using the duckOthers option as follows, but it doesn't work: let appAudioSession = AVAudioSession.sharedInstance() do { try appAudioSession.setCategory(.playAndRecord, mode: .default, options: .duckOthers) Maybe this is because there's one session for the entire app, and ApplicationMusicPlayer is using it? This is a fairly critical problem for my application, since Music content is always much louder than locally recorded content. Any insight appreciated.

if balloon == yellow1_balloon { soundFile = "Sounds/newblop.wav" playSound() balloon.isHidden = true poppedImages.isHidden = false poppedImages.animationImages = ["popyellow-1","popyellow-2","popyellow-3","popyellow-4","popyellow-5","popyellow-6","popyellow-7"] .compactMap({ name in UIImage(named: name) }) let x:CGFloat = yellow1_balloon.frame.origin.x let y:CGFloat = yellow1_balloon.frame.origin.y poppedImages.frame.origin.x = x poppedImages.frame.origin.y = y poppedImages.animationDuration = 1.0 poppedImages.animationRepeatCount = 1 poppedImages.startAnimating() score = score + 10 scoreLbl.text = String(score) return } x,y cordinates are always the same a when yellow1_balloon is first created and not where it ends up after being touched.

I would like to save the depth map from ARDepthData as .tiff, but notice my output tiff distances are incorrect. Objects that are close are reported to be slightly farther away, and walls that are around 4 meters away from me have a recorded value of 2 meters. I am using this code to write the tiff: import UIKit # Save method extension CVPixelBuffer { func saveDepthMapToTIFF(to path: URL) { let ciImage = CIImage(cvPixelBuffer: self) let context = CIContext() do { try context.writeTIFFRepresentation( of: ciImage, to: path, format: .Lf, colorSpace: CGColorSpaceCreateDeviceGray() ) } catch { print("Failed to write TIFF: \(error)") } } } # Calling the save arFrame.sceneDepth?.depthMap.saveDepthMapToTIFF(to: depthMapPath) I am reading the file like this in Python import tifffile depth_map = tifffile.imread("test.tiff") plt.imshow(depth_map) plt.colorbar() which creates this image: The farthest parts of the room should be around 4 meters, not 2. The dark blue spot on the lower right is closer than half a meter away. Notably the depth map contains distances from the camera plane to each region, not the distance from the camera sensor to the region. Even correcting for this though, the depth map remains about the same. Is there an issue with how I am saving the depth image? Is there a scale factor or format error?

I am using ReplayKit's RPScreenRecorder to record my app. When I use it in a mixed immersive space, nothing is actually recorded. The video is entirely blank. Is this a feature or a bug? I am trying to record everything the user sees, including passthrough. Is there another way to do this?

I filed FB13689023 for this since it is clearly unexpected. Non Apple Music library tracks are not returned on macOS using MusicLibraryRequest. I tried querying by artist where I only get Apple Music tracks, and by id where I don't get the track. On iPhone and iPad I was able to get both AM and non-AM tracks, that's how I got a valid id to try on macOS. Sync Library is on. The build targets My Mac (Designed for iPad). I'm using Xcode 15.3 and I'm on Sonoma (14.4). Any help is appreciated...

I'm trying to find a library item by title and artist but it returns 0 items. Example below for existing track in my library. With title filter commented out, it successfully gives me all library items for that artistName. If I add the title filter, or have only the title filter, I get 0 items. Why is that? var request = MusicLibraryRequest<MusicKit.Track>() // request.filter(matching: \.title, equalTo: "Crises (Remastered 2013)") request.filter(matching: \.artistName, equalTo: "Mike Oldfield") let response = try await request.response() I can find the track by filtering the returned tracks by artist, but I feel this might not be an ideal approach if I have a bunch of tracks to find, possibly by different artists. The reason I'm not querying by id is that I'm planning to do this sort of query for non Apple Music items and if I'm not mistaken there is no cross-device id for those (even with Sync Library on). If I have the app on multiple devices with the same Apple ID looking at the same library, I want device 2 to find the track you interacted with on device 1. If there are better ways to solve this, any ideas are welcome. Appreciate any help.

I was about to finally sign up for the Apple Music affiliate program since one of my apps does provide the MusickKit Subscription Offer. However, it looks like it was renamed and restricts usage to only artists and record labels. (https://partners.applemediaservices.com) Is this correct? Can I as an indie developer not earn commission of Apple Music that I drive from my apps?

After thoroughly scouring the internet numerous times, I came to the realization that Apple has not documented their User Authentication flow. Instead, developers are often directed to use their JavaScript solution, which proves to be insufficient and impractical for many projects. Could we please request a comprehensive documentation outlining the process of generating a Music User Token from the Developer Token? This would greatly benefit developers seeking to integrate Apple Music functionality into their projects.

Hello everyone, my name is Joshua Osagie. For 2 months now, I have been trying to build my own music application, but unfortunately, I can’t because I was thinking I would get an API from maybe Apple Music or Spotify that will grant me access to over 100 million music. Even if the API is paid for, I have been doing my research, but then it's kind of impossible. So please, if anyone has an idea on what I can do to bring this application to life, I will really appreciate it. Or if anyone could share me an idea on how to get over millions of music on my app, I will be really grateful.

I'm working on an application that aims to deliver a DJ-like experience by overlapping songs and implementing volume fading. During development, I've encountered a roadblock due to the MusicPlayerController singleton behavior in iOS, which seems to only support playback of one audio stream at a time and doesn't support overlapping of songs or fading volume between tracks. I understand that Apple Music content is protected and that playback through Apple MusicKit must respect the DRM and licensing agreements. However, I've noticed an application called "Mixonset" that seems to be able to stream songs from Apple Music, use the music player, and create an overlapping effect of songs for users. Could anyone share insights on how Mixonset might be achieving this within the constraints of the Apple MusicKit? Is there any approach that I could explore to implement similar functionality, such as overlapping songs or crossfading while adhering to Apple's guidelines and without violating any terms of service? Any advice or direction towards documentation and API capabilities that could support these features would be greatly appreciated. Thank you for your assistance.

Under Sonoma 14.4 the compression option doesn't work with PNG images. It works for JPG/HEIF. Preview can export PNG file to HEIC with compression option. What am I missing? Previously this has worked. I am trying with 0.01 and 0.9 as compression quality and the file size is the same for PNG. Is Preview using some trick to convert the image using ciContext.createCGImage? PS: Compression option of 1.0 was broken under 14.4 RC and Preview created empty file. func heifImageDataUsingDestination(at url: URL, compressionQuality : CGFloat) -> Data? { guard let imageSource = CGImageSourceCreateWithURL(url as CFURL, nil) else { return nil } guard let cgImage = CGImageSourceCreateImageAtIndex(imageSource, 0, nil) else { return nil } var mutableData = NSMutableData() guard let imageDestination = CGImageDestinationCreateWithData(mutableData, "public.heic" as CFString, 1, nil) else { return nil } let options = [ kCGImageDestinationLossyCompressionQuality: compressionQuality ] as CFDictionary CGImageDestinationAddImage(imageDestination, cgImage, options) let success = CGImageDestinationFinalize(imageDestination) if success { return mutableData as Data } return nil } func heifImageDataUsingCIContext(at url: URL, compressionQuality : CGFloat) -> Data? { guard let ciImage = CIImage(contentsOf: url) else { return nil } let context = CIContext() let colorspace = ciImage.colorSpace ?? CGColorSpaceCreateDeviceRGB() let options = [CIImageRepresentationOption(rawValue: kCGImageDestinationLossyCompressionQuality as String) : compressionQuality] return context.heifRepresentation(of: ciImage, format: .RGBA8, colorSpace: colorspace, options: options) }

Hi everyone! Are there any plans or existing alternatives to include the date a track was added to a playlist within Apple Music's API[1]? This functionality exists on Spotify[2] (with their "added_at" attribute), and it would be helpful for ordering tracks retrieved from playlists. Thank in advance for any help!
