I am using MusicKit ApplicationMusicPlayer to play music in my app. Everything works fine as long as I'm not playing large playlists that contain hundreds of songs. When I to play collection of songs that is larger than around 300 I'm always getting the error message saying:
"Prepare to play failed" UserInfo={NSDebugDescription=Prepare to play failed, NSUnderlyingError=0x121d42dc0 {Error Domain=MPMusicPlayerControllerErrorDomain Code=9 "Remote call timed out" UserInfo={NSDebugDescription=Remote call timed out}}}))
It doesn't matter if songs are downloaded to the device or not.
I am aware that there is another initializer for player's queue that accepts Playlist instances but in my app users can choose to sort playlist tracks in different order than the default and that makes using that initializer not feasible for me.
I tried everything I could think of, I tried to fall back on MPMusicPlayerController and pass array of MPMusicPlayerPlayParameters to it but the result was the same.
typealias QueueEntry = ApplicationMusicPlayer.Queue.Entry
let player = ApplicationMusicPlayer.shared
let entries: [QueueEntry] = tracks
.compactMap {
guard let song = $0 as? Song else { return nil }
return QueueEntry(song)
}
Task(priority: .high) { [player] in
do {
player.queue = .init(entries, startingAt: nil)
try await player.play() // prepareToPlay failed
} catch {
print(error)
}
}
I have old ScreenCaptureKit sample downloaded on Oct 2022.
That sample worked on Oct 2022. But it does not work on Apr 2024 on Sonoma 14.4.1 M1 MacBook. It only shows black screen.
I also download updated ScreenCaptureKit sample and test it. It works on Sonoma 14.4.1 M1 MacBook. I noticed latest sample have SCContentSharingPicker and other changes.
I have my screen capture application based on old ScreenCaptureKit sample. My app only shows black screen.
Do I have to add SCContentSharingPicker and SCContentSharingPickerObserver on my application for capturing screen on Sonoma?
Old way of screen capture without SCContentSharingPicker is not supported anymore on Sonoma?
In my app I play HLS streams via AVPlayer. It works well! However, when I try to download those same HLS urls via MakeAssetDownloadTask I regularly come across the error:
Download error for identifier 21222: Error Domain=CoreMediaErrorDomain Code=-12938 "HTTP 404: File Not Found" UserInfo={NSDescription=HTTP 404: File Not Found, _NSURLErrorRelatedURLSessionTaskErrorKey=(
"BackgroundAVAssetDownloadTask <CE9B10ED-E749-49FF-9942-3F8728210B20>.<1>"
), _NSURLErrorFailingURLSessionTaskErrorKey=BackgroundAVAssetDownloadTask <CE9B10ED-E749-49FF-9942-3F8728210B20>.<1>}
I have a feeling that the AVPlayer has a way to resolve this that the MakeAssetDownloadTask lacks. I am wondering if any of you have come across this or have insight.
Thank you!
BTW this is using Xcode Version 15.3 (15E204a) and developing for visionOS 1.0.1
I am using below commad line to generate AES-128 HLS,
mediafilesegmenter -iso-fragmented --encrypt-key-file=my.key -S -f /Volumes/Samsung/pattern/vision_pro/hls/*** /Volumes/Samsung/pattern/vision_pro/***.mov
but it always generates SAMPLE-AES, even I removed -S
#EXT-X-KEY:METHOD=SAMPLE-AES,URI="enc.key",IV=0x7316166d6a85f56f3d4606eaebc3aa44
How I can generate AES-128 HLS? Thanks.
Other than the big name HLS, anything else?

Does anyone have a ready-made script/shortcut like the one shown in the video?
Is it possible to edit the Grouping of a song from the user's library using the Apple Music API?
According to what I read from the documentation, this is not possible, but this is something that I really would love, so, I better ask.
Thanks in advanced!

I have the conflict when i use replaykit. There is other app or system use the recording. I want my app can recognize them and let them use the replaykit preferentially.
I have a stream.m3u8 file with the following contents:
#EXTM3U
#EXT-X-VERSION:11
#EXT-X-DEFINE:QUERYPARAM="token"
#EXT-X-STREAM-INF:BANDWIDTH=400000,RESOLUTION=640x360
360.m3u8{$token}
#EXT-X-DEFINE:QUERYPARAM="token"
#EXT-X-STREAM-INF:BANDWIDTH=1000000,RESOLUTION=960x540
540.m3u8{$token}
#EXT-X-STREAM-INF:BANDWIDTH=2000000,RESOLUTION=1280x720
#EXT-X-DEFINE:QUERYPARAM="token"
720.m3u8{$token}
#EXT-X-STREAM-INF:BANDWIDTH=8000000,RESOLUTION=1920x1080
#EXT-X-DEFINE:QUERYPARAM="token"
1080.m3u8{$token}
#EXT-X-STREAM-INF:BANDWIDTH=16000000,RESOLUTION=3840x2160
#EXT-X-DEFINE:QUERYPARAM="token"
2160.m3u8{$token}
The requesting URL is https://example.com/stream.m3u8!?token= and I am using an iPhone 15 running iOS 17.1.
The QUERYPARAM substitution as described here is not working, because the requested URL for 540.m3u8 does not have a token appended it; I know this because I checked my apache error log.
The file is hosted on a Debian 11 server.
Have I implemented this correctly, and do I have the correct tech stack? Furthermore, what debugging tools should I be running to investigate further?
Could some tell what the relevant endpoint is for fetching all public list of a user playlist. I am able to fetch a one via the id but i want to fetch all in a single request without using authorization.
Dear Apple Developer Forum,
we have customers here complaining about not being able to play live streams (HLS FairPlay) with ou application anymore since having upgraded their phone to iOS 17.4.1.
We can't reproduce this problem in-house but the error code sent to ou analytics platform is CoreMediaErrorDomain error -12852 .
Would it be possible to get more information on this error especially the potential cause of this and if the app is not responsible how we can help our customers ?
Kind regards
Cédric
Hello,
I'm using CallKit to manage the AudioSession. When I deactivate it with the notifyOthersOnDeactivation option, interruptions don't seem to be working correctly when checking other apps. Can anyone assist me? This issue is unique to my app. Should I follow a specific timing for deactivation?
Is it possible to find IDR frame (CMSampleBuffer) in AVAsset h264 video file?
I have a camera application which aims to take images as close to simultaneously as possible from the wide and ultra-wide cameras. The AVCaptureMultiCamSession is setup with manual connections. Note: we are not using builtInDualWideCamera with constituent photo delivery enabled since some features we use are not supported in that mode.
At the moment, we are manually trying to synchronize frames between the two cameras, but we would like to use the AVCaptureDataOutputSynchronizer to improve our results.
Is it possible to synchronize the wide and ultra-wide video outputs? All examples and docs that I've found show synchronization with video and depth, metadata, or audio, but not two video outputs.
From my testing, I've found that the dataOutputSynchronizer either fires with the wide video output, or the ultra video output, but never both (at least one is nil), suggesting that they are not being synchronized.
self.outputSync = AVCaptureDataOutputSynchronizer(dataOutputs: [wideCameraOutput, ultraCameraOutput])
outputSync.setDelegate(self, queue: .main)
...
func dataOutputSynchronizer(_ synchronizer: AVCaptureDataOutputSynchronizer, didOutput synchronizedDataCollection: AVCaptureSynchronizedDataCollection) {
guard let syncWideData: AVCaptureSynchronizedSampleBufferData = synchronizedDataCollection.synchronizedData(for: self.wideCameraOutput) as? AVCaptureSynchronizedSampleBufferData,
let syncedUltraData: AVCaptureSynchronizedSampleBufferData = synchronizedDataCollection.synchronizedData(for: self.ultraCameraOutput) as? AVCaptureSynchronizedSampleBufferData else {
return;
}
// either syncWideData or syncUltraData is always nil, so the guard condition never passes.
}
Hello,
Problem
I am having the exact same issue as described here : https://forums.developer.apple.com/forums/thread/693310
From my understanding of the answers on this topic, it appears to be a problem on the Server Side.
Is it still the case or perhaps I am missing something ?

Am I missing something ? Is it a server side issue ? If so, when will it be fixed ? Otherwise, what is wrong with my approach ?
Hi,
Is it possible to get the various audio variants for a given song ID, I am unable to find any documentation for this online. In particular, could I see if Dolby Atmos is available for the track?
Here is an example of a request I am sending: https://api.music.apple.com/v1/catalog/us/songs/1168770969
