After updating to 18.3 my iPad 7th generation has no sound and will not play videos

Hey everyone😊, I am building an app that includes a live camera feed preview. That's all I need to do along side identifying the images with createML's image classification. I don't need to capture images at all. I've seen some very complicated tutorials. I just want to use a couple of lines of code.

Hey, I have a complex CIFilter chain I'm trying to debug to improve processing time. Is there any documentation on what all the colours mean and the naming, e.g. sRGB Linear_to_workspace? Thanks Alex

I set both the AVCapturePhotoOutput and the AVCapturePhotoSettings with maxPhotoDimensions = .init(width: 8064, height: 6048), but still get the 12mp photo.

I've got a web app built with MusicKit that displays a list of songs. I have player controls for play, pause, skip next, skip, previous, toggle shuffle and set repeat mode. All of these work by using music. The play button, when nothing is playing and nothing is in the queue, will enqueue all the tracks and start playing with the below, for example: await music.setQueue({ songs, startPlaying: true }); I've implemented a progress slider based on feedback from the "playbackProgressDidChange" listener. Now, how in the world can I set the volume? This seems like it should be simple, but I am at a complete loss here. The docs say: "The volume of audio playback, which is set directly on the HTMLMediaElement as the HTMLMediaElement.volume property. This value ranges between 0, which would be muting the audio, and 1, which would be the loudest possible." Given that all my controls work off the music instance, I don't understand how I can do that. In this video from WWDC 2022, music web components are touched on briefly. These are also documented very sparsely. The volume docs are here. For the life of me, I can't even get the volume web component to display in the UI. It appears that MusicKit Web is hobbled compared to the native implementation, but surely adjusting volume shouldn't be that hard right? I'd appreciate any insight on how to do this, including how to get web components to work (in a Next JS app). Thanks.

ApplicationMusicPlayer with queue created from playlist crashes with random occurrence shortly after skipping back or forth using controls embedded in the notification, with the error on console log: applicationController: xpc service connection interrupted. I've noticed that the issue occurs more frequently the shorter is time between skipping entries. Since ApplicationMusicPlayer is run on a remote process, the main app does not crash, but the music stops playing without any exception, and the playback control turns uninitiated. Here is how I'm initiating the queue: let entries = playlist .with(.entries).entries! .map { ApplicationMusicPlayer.Queue.Entry($0) } ApplicationMusicPlayer.shared.queue = .init( entries, startingAt: entries.last ) Please give me some tips on how to solve this. EDIT: The issue does not occur when navigating quickly through the station.

I'm building a camera app that does some post processing after the photo has been taken. With 12MP the processing is pretty good, but larger images 24MP is very slow. I created a very simple example to demonstrate the issue, which is loading an image and the rendering it to data. let context = CIContext() let imageUrl = Bundle.main.url(forResource: "12mp", withExtension: "jpg")! let data = try! Data(contentsOf: imageUrl) let ciImage = CIImage(data: data)! let start = CFAbsoluteTimeGetCurrent() let data = context.jpegRepresentation(of: ciImage, colorSpace: context.workingColorSpace!) print(data?.count) print("Resize Completed: " + String(CFAbsoluteTimeGetCurrent() - start)) Running this code on an iPhone 16 Pro with different images produces these benchmarks: 12MP => 0.03s 24MP => 1.22s 48MP => 2.98s I understand that processing time will increase with resolution but it doesn't seem linear. I have tried setting different CiContext options such as .useSoftwareRenderer: false but it has made no difference. From profiling the process it looks like the JPEG decoding is the bottle neck. This is for a 48MP Image: Is there any way this can be improved?

Hi, I have been working on a project that enables users to listen to their favorite music using a streaming service, which so far was Spotify. The app had a programmable 3D/2D interface with the ability to connect to devices in your home and have them react to music. As of September 2024, Spotify decomissioned their Audio Analysis API. I have seen other posts mention playing Apple Music through AVFoundation, which would break DRM and so it’s not supported. However, the Spotify Audio Analysis API does not allow for a full frequency reconstruction. It is entirely temporal data on beats, kicks, loudness, and timbre changes, which themselves are operators on the spectral data from the FFT. It would be very useful for the developer community if we get the ability to do this and it will probably Apple Music among developers and those who use their apps a lot more. Would love to hear your thoughts about this and Happy New Year!

I see in most of the old sample codes from Apple that when using AVAssetWriter to append audio, video, and metadata samples in a real time camera recording setup, calls to .append(sampleBuffer) are either synchronised using an NSLock or all the samples are sent to the asset writer on the same dispatch queue thereby preventing concurrent writes. However I can't find any documentation that calls to assetWriterInput.append(sampleBuffer) for different media samples such as Audio and Video should not be done concurrently. Is it not valid for these methods to be executed in parallel for instance? `videoSamplesAssetWriterInput.append(videoSampleBuffer)` from DispatchQueue 1 `audioSamplesAssetWriterInput.append(audioSampleBuffer)` from DispatchQueue 2

I'm trying to load Music Kit on the server with solid js. I can confirm that my implementation has been sufficient to return authentication tokens and for MusicKit.isAuthorized to return true. My issue is that if I reload the page, it only succeeds intermittently (perhaps 25% of the time?). My question is - what is wrong with my implementation? Removing the async keyword ensures it loads every time but playing and queuing music no longer works. I'm currently assuming this is an SSR issue but the docs haven't explicitly specified this isn't possible. I have the following boilerplate: export default createHandler( () => ( <StartServer document={({ assets, children, scripts }) => { return ( <html lang="en"> <head> <meta name="apple-music-developer-token" content={authResult.token} /> <meta name="apple-music-app-name" content="app name" /> <meta name="apple-music-app-build" content="1978.4.1" /> {assets} <script src="https://js-cdn.music.apple.com/musickit/v3/musickit.js" async /> </head> <body> <div id="app">{children}</div> {scripts} </body> </html> ) }} /> )) When I first load my app, I'll encounter: musickit.js:13 Uncaught TypeError: Cannot read properties of undefined (reading 'node') at musickit.js:13:10194 at musickit.js:13:140 at musickit.js:13:209 The intermittence signals an issue relating to the async keyword. An expansion on this issue can be found here.

Hi, I am trying to enable the default MIDINetworkSession in a Catalyst app on MacOS like this: MIDINetworkSession.default().isEnabled = true MIDINetworkSession.default().connectionPolicy = .anyone In the AppSandbox I have both incoming and outgoing network connections enabled. And I also added the NSLocalNetworkUsageDescription key to the info.plist. Bonjour services are also added to the info.plist: NSBonjourServices _apple-midi._udp. Nevertheless the session stays disabled. Running the same code works just fine on iOS. Is there any special setup I need to make on MacOS to enable the MIDINetworkSession? Thanks!

for a while i had one photo widget (no special app, just the standard apple one) and it was set to shuffle to an album of pics of my bf. no problems at all. a few weeks later i added one to shuffle through an album of pics of my cat, and that one worked fine, but it made the one of my bf stop working, and it just showed a blank white widget, no error message or anything. so i removed the one of my cat hoping the one of my bf would go back to working, and it didn’t. i only have the widgets for find my, my bank, and then apps on my home screen otherwise.

What is the purpose of AdjustmentsSecondary.data included in the PHAssetResource for a cleaned-up image? When using creationRequest.addResource, what should be set for the PHAssetResourceType? If I set the PHAssetResourceType as follows to create an asset, it appears correctly in the camera roll. However, when attempting to edit the image in the Photos app, the app crashes: IMG_5332.HEIC → .photo FullSizeRender.HEIC → .fullSizePhoto Adjustments.plist → .adjustmentData AdjustmentsSecondary.data → .adjustmentData

Hi everyone, I wanted to bring up a question about Core Audio and its potential for future updates or improvements, specifically regarding latency optimization. As someone who relies on Core Audio for real-time audio processing, any enhancements in this area would be incredibly beneficial for professionals in the industry. Does anyone know if Apple has shared any plans or updates regarding Core Audio’s performance, particularly for low-latency applications? I’d appreciate any insights or advice from the community! Thanks so much! Best, Michael

Hello! I am building a video camera app and trying to implement Apple log for iPhone 15 Pro and 16 Pro. I am not seeing a lot of documentation on it and notice the amount of apps that use it on the app is rather limited. Less an 5 to be exact. Is Apple Log recording a feature that is accessible to developers? Here is a link to documentation: https://developer.apple.com/documentation/avfoundation/avcapturecolorspace/applelog

We integrate with FCP X using a custom share destination and the Apple Script interface. This has been working fine until the the recent version 11 update of FCP X. With this update we are no longer receiving the open event when the export has completed. We get the apple event to creat the Asset and the file is exported to the location we set in the response. There is just no open event after that. I suspect something is wrong with our scripting support but I have no idea what or how to troubleshoot. This works fine in 10.8.1 and below.

Can some one please answer me How Can I update the cookies of the previously set m3u8 video in AVPlayer without creating the new AVURLAsset and replacing the AVPlayer current Item with it

Here we are focusing to change the cookie at every 120 seconds while playing , in apple avplayer we can't modify cookie after initialisation due to that we followed the approach to using " Resource loader delegate " to pass cookie as a header value . What I notice is that the playlist file (.m3u8) gets downloaded correctly. Then video file (.m4a) some chunks also gets downloaded. I know that the .ts file is downloaded because I can see the GET request completing on the web server with status 200. I also set a breakpoint at the following line: loadingRequest.dataRequest?.respond(with: data) immediately got error from avplayer status as "The operation could not be completed. An unknown error occurred (-12881) From core media" Need confirmation on why I am unable to load HLS using resource loader. is it possible to update cookie value while paying continuously on avplayer. override func viewDidLoad() { super.viewDidLoad() // Do any additional setup after loading the view. let urlString = "localhost://demo.unified-streaming.com/k8s/features/stable/video/tears-of-steel/tears-of-steel.ism/.m3u8" guard let url = URL(string: urlString) else { print("Invalid URL") return } //Create cookie to prepare for player asset let cookie = HTTPCookie(properties: [ .name: "dazn-token", .value: "cookie value", .domain: url.host() ??
