Starting with Sonoma 14.2 it is not possible any longer to connect canon cameras to an app via USB using Canon's EDSDK framework. This has been working fine up to Sonoma 14.1. The app using the EDSDK is not crashing, but the SDK is not reporting back any connected cameras any longer. The camera is connected and can be seen in the system report as well as in e.g. gphoto2 and even in the EOS Utility Software. It seems that 14.2 introduced some breaking change to the access to cameras from within apps. I've tried upgrading to the newest EDSDK version and checked with and without App Sandbox. There is no way to find the camera any longer on 14.2.

Since upgrade to iOS17 WebRTC playback have problems on going fullscreen - video element is rapidly changing its dimensions while taking full screen size and animation seems very glitchy. I'm observing this issue on every webrtc players available, so I think the problem is in the mobile safari. Is there any way to prevent resizing of video on fullscreen?

Hi, I'm trying to play multiple video/audio file with AVPlayer using AVMutableComposition. Each video/audio file can process simultaneously so I set each video/audio in individual tracks. I use only local file. let second = CMTime(seconds: 1, preferredTimescale: 1000) let duration = CMTimeRange(start: .zero, duration: second) var currentTime = CMTime.zero for _ in 0...4 { let mutableTrack = composition.addMutableTrack( withMediaType: .audio, preferredTrackID: kCMPersistentTrackID_Invalid ) try mutableTrack?.insertTimeRange( duration, of: audioAssetTrack, at: currentTime ) currentTime = currentTime + second } When I set many audio tracks (maybe more than 5), the first part sounds a little different from original when it starts. It seems like audio's front part is skipped. But when I set only two tracks, AVPlayer plays as same as original file. avPlayer.play() How can I fix it? Why do audio tracks affect that don't have any playing parts when start? Please let me know.

I was watching a video when I noticed a periodical popping sound. Thought it was a problem with the video, but the issue persists on all other videos or sound tracks. Gets very annoying! Quite disappointed to find this flaw in a brand new Mac Book Pro.

I'm involved in development on an iOS app for home security and alarm systems. There is recently a lot of negative feedback from customers about how low the notification sounds are since iOS17. Much of the feedback centers around the inability to control the volume of the notification sounds. My question is: if our app uses custom notification sounds, are these impacted by the volume changes made in iOS 17? I know previous versions of iOS allow you to control "Ringtone and Alert" volume in settings (with a volume slider). Is this same control still available for custom notification sounds within our app?

I was play a pcm(24kHz 16bit) file with AudioQueue, and it mix with other sound( 192kHz 24bit) named sound2. Setting for AVAudioSession as: category (AVAudioSessionCategoryPlayback), options (AVAudioSessionCategoryOptionMixWithOthers|AVAudioSessionCategoryOptionDuckOthers) when playing pcm the sound2 should pushed volume lower as setting. BUT, there has a absolutly mute keep 0.5 second when the sound2 become low, and after a 0.5s mute the pushed lower sound came out. It only become in sound2 situation(192kHz, 24bit). if the sound2's quality lower everything is OK.

Hello, I'm currently investigating the possibility of accessing my photos stored on my iCloud via a dedicated API, in order to create a photo portfolio. However, after extensive research, I haven't found any documentation or public API allowing such access. I wonder if there are any future plans to make such an API available to third-party developers. I would be grateful if you could provide me with information regarding the possibility of accessing an API for Apple Photos or any other solution you might suggest. Thank you for your attention and assistance. Yours sincerely Owen

I wish to parse the bitstream of HEVC video with alpha (specific video format reference WWDC2019: https://developer.apple.com/videos/play/wwdc2019/506). Taking the 'puppets_with_alpha_hevc.mov' file from 'Using HEVC Video with Alpha' as an example, I would first extract the HEVC bitstream, then parse its fields. When it comes to the VPS field, as I reach the vps_extension, I find that the bitstream in 'puppets_with_alpha_hevc.mov' does not conform to the HEVC standard document, preventing further parsing. Besides the 'HEVC Video with Alpha Interoperability Profile.pdf', are there any more detailed documents describing the HEVC video with alpha format? Also, is there anyone who can encode or decode HEVC with alpha videos on systems other than macOS?

Simple question: can I shoot log using the new MVHEVC format for spatial video for viewing on the Vision Pro?

I'm trying to show likeCommand and dislikeCommand on the Lock Screen of a music player without success. Are they still supported ? Is there any special configuration on the player or the track for them to show? My current code which works for playCommand looks like this MPRemoteCommandCenter.shared().likeCommand.addTarget { [unowned self] _ in if isPlaying { return .success } return .commandFailed }

Our initial understanding was that this event is fired only when the DRM blocks the video playback. However, in the present case we see that it is called even when playback is successful(playback with external screen connected). To assess whether playback remains functional when the 'outputObscuredDueToInsufficientExternalProtection' event is triggered, we conducted two specific scenario tests: 1) playing an asset without any DRM restrictions, and 2) playing an asset with DRM restrictions. Result: In our analysis, we have identified that the 'outputObscuredDueToInsufficientExternalProtection' flag always remains set to one, even when playback is successful. However, it is expected to be set to zero when the playback is successful. working case log when playback is successful: default 13:23:19.096682+0530 AMC ||| observeValueForKeyPath = "outputObscuredDueToInsufficientExternalProtection" object = <AVPlayer: 0x281284930> change kind = { kind = 1; new = 1; old = 0; } non working case log when playback came as black screen: default 13:45:21.356857+0530 AMC ||| observeValueForKeyPath = "outputObscuredDueToInsufficientExternalProtection" object = <AVPlayer: 0x281c071e0> change kind = {kind = 1; new = 1; old = 0; } We searched through related documents and conducted a Google search, but we couldn't find any information or references related to this behavior of the 'outputObscuredDueToInsufficientExternalProtection' event. It would be really appreciated if any one can help us with this!

We have a logic in the SDK which stops playback when the outputObscuredDueToInsufficientExternalProtection event is fired by the player. Our initial understanding was that this event is fired only when the DRM blocks the video playback. However, in the present case we see that it is called even when playback is successful(playback with external screen connected). To determine whether playback still functions when the 'outputObscuredDueToInsufficientExternalProtection' event is triggered, we temporarily disabled the playback stop implementation that occurs after the event is triggered. code snippet - Observations - After this event was triggered during mirroring playback using a Lightning to HDMI connector, our expectation was that the playback would result in a black screen. However, to our surprise, the playback worked perfectly, indicating that this event is being triggered even when there are no DRM restrictions for that asset's playback. Another scenario we tested involved using a VGA connector. In this case, we observed that the 'outputObscuredDueToInsufficientExternalProtection' event was triggered. Initially, playback started as expected when we commented out the playback stop implementation. However, after a few seconds of playback, the screen went black. In the first scenario, it was unexpected for the 'outputObscuredDueToInsufficientExternalProtection' event to trigger, as the playback worked without issues even after the event was triggered. However, in the second scenario, the event was triggered as expected. The issue we identified is that this event is being triggered irrespective of the presence of DRM restrictions for the asset. In another scenario, we attempted to differentiate between the VGA and HDMI connectors to determine if such distinction was possible. However, we found that the VGA cable was also recognized as an HDMI port in the case of iOS. We also tested the issue on an older iOS version (iOS 14.6.1) to see if the problem persisted. Surprisingly, we found that the 'outputObscuredDueToInsufficientExternalProtection' event was triggered even in the older OS version. Conclusion: In our analysis, we have identified that the 'outputObscuredDueToInsufficientExternalProtection' flag always remains true even though output is not obsecured. working case log: default 13:23:19.096682+0530 AMC ||| observeValueForKeyPath = "outputObscuredDueToInsufficientExternalProtection" object = <AVPlayer: 0x281284930> change kind = { kind = 1; new = 1; old = 0; } non working case log: default 13:45:21.356857+0530 AMC ||| observeValueForKeyPath = "outputObscuredDueToInsufficientExternalProtection" object = <AVPlayer: 0x281c071e0> change kind = {kind = 1; new = 1; old = 0; } We searched through related documents and conducted a Google search, but we couldn't find any information or references related to this behavior of the 'outputObscuredDueToInsufficientExternalProtection' event.

Hello, I'm developing a PWA, this app needs to use some features of the Audio API. one feature is MediaSource I get to work on all devices except iPhone. according to https://caniuse.com/?search=MediaSource it isn't supported on iPhone. are the plans to support this in the future? The application that I'm building creates a audioContext and audio elament. after that creates a buffer for type 'audio/mp4; codecs="mp4a.40.2'. and trys to fetch chunks of data into it. after the first chunk is loaded it starts playing. It works on my Mac and iPad I also tested on android. Hello, I'm developing a PWA (Progressive Web App). This app needs to use some features of the Audio API.

Hi, I am trying to store persistent changes to the photo library. I know I can use a PHPersistentChangeToken to get the changes since that token, but I am not sure how to serialize this object and save it into a file. I am also wondering if you can serialize a PHPersistentChangeFetchResult and store that in a file. Cheers.

Hello, I want to create a photo portfolio (in VueJS) and I'd like to use my icloud photo library to store the photos. Is there an API that allows me to access one or more albums in my photo library?

Hi community I'm developing an application for MacOS and i need to capture the mic audio stream. Currently using CoreAudio in Swift i'm able to capture the audio stream using IO Procs and have applied the AUVoiceProcessing for prevent echo from speaker device. I was able to connect the audio unit and perform the echo cancellation. The problem that i'm getting is that when i'm using AUVoiceProcessing the gain of the two devices get reduced and that affects the volume of the two devices (microphone and speaker). I have tried to disable the AGC using the property kAUVoiceIOProperty_VoiceProcessingEnableAGCbut the results are the same. There is any option to disable the gain reduction or there is a better approach to get the echo cancellation working?

The native camera app on iPhone 15 can record videos directly in external hard drive. Is there an API to achieve the same in Photos framework?
