I am capturing a screenshot with SCScreenshotManager's captureImageWithFilter. The resulting PNG has the same resolution as the PNG taken from Command-Shift-3 (4112x2658) but is 10x larger (14.4MB vs 1.35MB). My SCStreamConfiguration uses the SCDisplay's width and height and sets the color space to kCGColorSpaceSRGB. I currently save to file by initializing a NSBitmapImageRep using initWithCGImage, then representing as PNG with representationUsingType NSBitmapImageFileTypePNG, then writeToFile:atomically. Is there some configuration or compression I can use to bring down the PNG size to be more closely in-line with a Command-Shift-3 screenshot. Thanks!

When I receive the InterruptionBegan notification (the interruption type is AVAudioSessionInterruptionTypeBegan) , I pause playing music. When I receive the InterruptionEnded notification (the interruption type is AVAudioSessionInterruptionTypeEnded), I resume playing music. however, sometimes i has got the error code: AVAudioSessionErrorCodeCannotInterruptOthers (560557684) If some malicious app to take up the audio, which leads to the third party app music playback recovery fails, an error AVAudioSessionErrorCodeCannotInterruptOthers. In this case, can we know which apps are maliciously hogging the audio?

Doing some testing around player behaviour when a license expires in Safari on MacOS. I had the following outcomes: On Safari 17.4.1 on an intel based Mac running Ventura, playback stopped when the license expired. On Safari 17.4.1 on an M3 running Sonoma, playback stalled briefly, and then continued to play unlimited. On Safari 16.5.2 on an M2 running Ventura, playback stalled briefly, and then continued to play unlimited. When playback stalled briefly, was at the time the license expired. I parsed the license and everything is set correctly for a lease license type: { "version" : 1, "payloadLength" : 1072, "iv" : "0H9NCXLQeh1ziYpmJXsnwQ==", "assetId" : "䙁㉌䉃\u0000\u0000\u0000", "hdcp" : "TYPE_0_REQUIRED", "contentKeyDuration" : { "leaseDurationSeconds" : 300, "rentalDurationSeconds" : 0, "persistenceAllowed" : false }, "keyType" : "Lease" } I cannot find any information relating to this behaviour. Per the docs for FPS, a lease license type: If the content key is not renewed, the Apple device stops the playback when the lease expires. Which is what is observed on the intel based macbook.

This code to write UIImage data as heic works in iOS simulator with iOS < 17.5 import AVFoundation import UIKit extension UIImage { public var heic: Data? { heic() } public func heic(compressionQuality: CGFloat = 1) -> Data? { let mutableData = NSMutableData() guard let destination = CGImageDestinationCreateWithData(mutableData, AVFileType.heic as CFString, 1, nil), let cgImage = cgImage else { return nil } let options: NSDictionary = [ kCGImageDestinationLossyCompressionQuality: compressionQuality, kCGImagePropertyOrientation: cgImageOrientation.rawValue, ] CGImageDestinationAddImage(destination, cgImage, options) guard CGImageDestinationFinalize(destination) else { return nil } return mutableData as Data } public var isHeicSupported: Bool { (CGImageDestinationCopyTypeIdentifiers() as! [String]).contains("public.heic") } var cgImageOrientation: CGImagePropertyOrientation { .init(imageOrientation) } } extension CGImagePropertyOrientation { init(_ uiOrientation: UIImage.Orientation) { switch uiOrientation { case .up: self = .up case .upMirrored: self = .upMirrored case .down: self = .down case .downMirrored: self = .downMirrored case .left: self = .left case .leftMirrored: self = .leftMirrored case .right: self = .right case .rightMirrored: self = .rightMirrored @unknown default: fatalError() } } } But with iOS 17.5 simulator it seems to be broken. The call of CGImageDestinationFinalize writes this error into the console: writeImageAtIndex:962: *** CMPhotoCompressionSessionAddImage: err = kCMPhotoError_UnsupportedOperation [-16994] (codec: 'hvc1') On physical devices it still seems to work. Is there any known workaround for the iOS simulator?

So i meant to make a shared album but made a shared library. That being said, I deleted the shared album but my family can not remove it from the phones

I have an app that has the camera continuously running, as it is doing its own AI, have zero need for Apple'video effects, and am seeing a 200% performance hit after updating to Sonoma. The video effects are the "heaviest stack trace" when profiling my app with Instruments CPU profiler (see below). Is forcing your software onto developers not something Microsoft would do?

Hello everyone, I have been receiving this same crash report for the past month whenever I try and export a Final Cut Pro project. The FCP video will get to about 88% completion of export, then the application crashes and I get the attached report. Any leads on how to fix this would be greatly appreciated! Thank you. -Lauren

The above is the extra_data in the lhvC box in the 3D format of Apple's Vision Pro, which only contains sps/pps; I can know that 0xa1 is sps nultype, 0x00 01 is the number of sps, and 0x00 17 is the length. But what is the 0x01 f0 00 fc c3 02 at the beginning, and I can't find the corresponding definition.

Since iOS 12 it has become difficult to detect the end of playback using the system music player. In earlier iOS versions, the now playing item would be set nil and you would receive a notification that the player stopped. In iOS 12 and later, nowPlayingItem still contains the current song and the only notification you get is MPMusicPlayerControllerPlaybackStateDidChangeNotification with the playbackState set to MPMusicPlaybackStatePaused. Pressing pause in my car (or any remote access) generates the same conditions making it difficult to correctly detect the difference. It would be nice if they added a notification that playback was done (similar to the other players). Any suggestions?

I'm using the systemMusicPlayer to play music and want to update the playback time using addObserver forKeyPath. [self setMusicPlayer: [MPMusicPlayerController systemMusicPlayer]]; I've tried these two methods: [self addObserver:self forKeyPath:@"musicPlayer.currentPlaybackTime" options:NSKeyValueObservingOptionNew | NSKeyValueObservingOptionInitial context:&musicPlayer]; [self.musicPlayer addObserver:self forKeyPath:@"currentPlaybackTime" options:NSKeyValueObservingOptionNew | NSKeyValueObservingOptionInitial context:&musicPlayer]; I do get the initial values for currentPlaybackTime in: -(void)observeValueForKeyPath:(NSString *)keyPath ofObject:(id)object change:(NSDictionary *)change context:(void *)context but I never get any calls when the player is playing the song (the whole point). If I set the currentPlaybackTime to a specific value (locating manually using a slider), I get calls with the values I set (useless since I know what I am setting them to). How are we supposed to track the playback time without just polling it constantly?

Hi everyone, I am having a problem on AVPlayer when I try to play some videos. The video starts for a few seconds, but immediately after I see a black screen and in the console there is the following error: <__NSArrayM 0x14dbf9f30>( { StreamPlaylistError = "-12314"; comment = "have audio audio-aacl-54 in STREAMINF without EXT-X-MEDIA audio group"; date = "2024-05-13 20:46:19 +0000"; domain = CoreMediaErrorDomain; status = "-12642"; uri = "http://127.0.0.1:8080/master.m3u8"; }, { "c-conn-type" = 1; "c-severity" = 2; comment = "Playlist parse error"; "cs-guid" = "871C1871-D566-4A3A-8465-2C58FDC18A19"; date = "2024-05-13 20:46:19 +0000"; domain = CoreMediaErrorDomain; status = "-12642"; uri = "http://127.0.0.1:8080/master.m3u8"; } )

I connect two AVAudioNodes by using - (void)connectMIDI:(AVAudioNode *)sourceNode to:(AVAudioNode *)destinationNode format:(AVAudioFormat * __nullable)format eventListBlock:(AUMIDIEventListBlock __nullable)tapBlock and add a AUMIDIEventListBlock tap block to it to capture the MIDI events. Both AUAudioUnits of the AVAudioNodes involved in this connection are set to use MIDI 1.0 UMP events: [[avAudioUnit AUAudioUnit] setHostMIDIProtocol:(kMIDIProtocol_1_0)]; But all the MIDI voice channel events received are automatically converted to UMP MIDI 2.0 format. Is there something else I need to set so that the tap receives MIDI 1.0 UMPs? (Note: My app can handle MIDI 2.0, so it is not really a problem. So this question is mainly to find out if I forgot to set the protocol somewhere...). Thanks!!

I'm trying to cast the screen from an iOS device to an Android device. I'm leveraging ReplayKit on iOS to capture the screen and VideoToolbox for compressing the captured video data into H.264 format using CMSampleBuffers. Both iOS and Android are configured for H.264 compression and decompression. While screen casting works flawlessly within the same platform (iOS to iOS or Android to Android), I'm encountering an error ("not in avi mode") on the Android receiver when casting from iOS. My research suggests that the underlying container formats for H.264 might differ between iOS and Android. Data transmission over the TCP socket seems to be functioning correctly. My question is: Is there a way to ensure a common container format for H.264 compression and decompression across iOS and Android platforms? Here's a breakdown of the iOS sender details: Device: iPhone 13 mini running iOS 17 Development Environment: Xcode 15 with a minimum deployment target of iOS 16 Screen Capture: ReplayKit for capturing the screen and obtaining CMSampleBuffers Video Compression: VideoToolbox for H.264 compression Compression Properties: kVTCompressionPropertyKey_ConstantBitRate: 6144000 (bitrate) kVTCompressionPropertyKey_ProfileLevel: kVTProfileLevel_H264_Main_AutoLevel (profile and level) kVTCompressionPropertyKey_MaxKeyFrameInterval: 60 (maximum keyframe interval) kVTCompressionPropertyKey_RealTime: true (real-time encoding) kVTCompressionPropertyKey_Quality: 1 (lowest quality) NAL Unit Handling: Custom header is added to NAL units Android Receiver Details: Device: RedMi 7A running Android 10 Video Decoding: MediaCodec API for receiving and decoding the H.264 stream

I have generated FCPXML, but i can't figure out issue: <?xml version="1.0"?> <fcpxml version="1.11"> <resources> <format id="r1" name="FFVideoFormat3840x2160p2997" frameDuration="1001/30000s" width="3840" height="2160" colorSpace="1-1-1 (Rec. 709)"/> <asset id="video0" name="11a(1-5).mp4" start="0s" hasVideo="1" videoSources="1" duration="6.81s"> <media-rep kind="original-media" src="file:///Volumes/Dropbox/RealMedia Dropbox/Real Media/Media/Test/Test AE videos, City, testOLOLO/video/11a(1-5).mp4"/> </asset> <asset id="video1" name="12(4)r8 mute.mp4" start="0s" hasVideo="1" videoSources="1" duration="9.94s"> <media-rep kind="original-media" src="file:///Volumes/Dropbox/RealMedia Dropbox/Real Media/Media/Test/Test AE videos, City, testOLOLO/video/12(4)r8 mute.mp4"/> </asset> <asset id="video2" name="13 mute.mp4" start="0s" hasVideo="1" videoSources="1" duration="6.51s"> <media-rep kind="original-media" src="file:///Volumes/Dropbox/RealMedia Dropbox/Real Media/Media/Test/Test AE videos, City, testOLOLO/video/13 mute.mp4"/> </asset> <asset id="video3" name="13x (8,14,24,29,38).mp4" start="0s" hasVideo="1" videoSources="1" duration="45.55s"> <media-rep kind="original-media" src="file:///Volumes/Dropbox/RealMedia Dropbox/Real Media/Media/Test/Test AE videos, City, testOLOLO/video/13x (8,14,24,29,38).mp4"/> </asset> </resources> <library> <event name="Untitled"> <project name="Untitled Project" uid="28B2D4F3-05C4-44E7-8D0B-70A326135EDD" modDate="2024-04-17 15:44:26 -0400"> <sequence format="r1" duration="4802798/30000s" tcStart="0s" tcFormat="NDF" audioLayout="stereo" audioRate="48k"> <spine> <asset-clip ref="video0" offset="0/10000s" name="11a(1-5).mp4" duration="0/10000s" format="r1" tcFormat="NDF"/> <asset-clip ref="video1" offset="12119/10000s" name="12(4)r8 mute.mp4" duration="0/10000s" format="r1" tcFormat="NDF"/> <asset-clip ref="video2" offset="22784/10000s" name="13 mute.mp4" duration="0/10000s" format="r1" tcFormat="NDF"/> <asset-clip ref="video3" offset="34544/10000s" name="13x (8,14,24,29,38).mp4" duration="0/10000s" format="r1" tcFormat="NDF"/> </spine> </sequence> </project> </event> </library> </fcpxml> Any ideas?

Is there any update for iOS17 in FairPlay? So far I have found no relevant information. iOS 16 is fine

Hi, I am developing iOS mobile camera. I noticed one issue related to the user privacy. when AVCaptureVideoStabilizationModeStandard is set to AVCaptureConnection which sessionPreset is 1920x1080Preset, after using system API to take a photo, the FOV of the photo will be bigger than preview stream and it will show more content especially in iPhone 15 pro max rear camera. I think this inconsistency will cause the user privacy issue. Can you show me the solution if I don't want to turn the StabilizationMode OFF? I tried other devices, this issue is ok but in iPhone 15pm this issue is very obvious. Any suggestions are appreciated.
