As of iOS 17.X a .mov (h264/alac) recording has a problem where the track length doesn't equal the container length. So if the Audio/Video tracks are 10.00 long, the fullVideo.mov could be 10.06 long. This does not happen with any version pervious to iOS 17. Anyone else experiencing this or have advice?

Hi there, I am building a camera application to be able to capture an image with the wide and ultra wide cameras simultaneously (or as close as possible) with the intrinsics and extrinsics for each camera also delivered. We are able to achieve this with an AVCaptureMultiCamSession and AVCaptureVideoDataOutput, setting up the .builtInWideAngleCamera and .builtInUltraWideCamera manually. Doing this, we are able to enable the delivery of the intrinsics via the AVCaptureConnection of the cameras. Also, geometric distortion correction is enabled for the ultra camera (by default). However, we are seeing if it possible to move the application over to the .builtInDualWideCamera with AVCapturePhotoOutput and AVCaptureSession to simplify our application and get access to depth data. We are using the isVirtualDeviceConstituentPhotoDeliveryEnabled=true property to allow for simultaneous capture. Functionally, everything is working fine, except that when isGeometricDistortionCorrectionEnabled is not set to false, the photoOutput.isCameraCalibrationDataDeliverySupported returns false. From this thread and the docs, it appears that we cannot get the intrinsics when isGeometricDistortionCorrectionEnabled=true (only applicable to the ultra wide), unless we use a AVCaptureVideoDataOutput. Is there any way to get access to the intrinsics for the wide and ultra while enabling geometric distortion correction for the ultra? guard let captureDevice = AVCaptureDevice.default(.builtInDualWideCamera, for: .video, position: .back) else { throw InitError.error("Could not find builtInDualWideCamera") } self.captureDevice = captureDevice self.videoDeviceInput = try AVCaptureDeviceInput(device: captureDevice) self.photoOutput = AVCapturePhotoOutput() self.captureSession = AVCaptureSession() self.captureSession.beginConfiguration() captureSession.sessionPreset = AVCaptureSession.Preset.hd1920x1080 captureSession.addInput(self.videoDeviceInput) captureSession.addOutput(self.photoOutput) try captureDevice.lockForConfiguration() captureDevice.isGeometricDistortionCorrectionEnabled = false // <- NB line captureDevice.unlockForConfiguration() /// configure photoOutput guard self.photoOutput.isVirtualDeviceConstituentPhotoDeliverySupported else { throw InitError.error("Dual photo delivery is not supported") } self.photoOutput.isVirtualDeviceConstituentPhotoDeliveryEnabled = true print("isCameraCalibrationDataDeliverySupported", self.photoOutput.isCameraCalibrationDataDeliverySupported) // false when distortion correction is enabled let videoOutput = AVCaptureVideoDataOutput() videoOutput.setSampleBufferDelegate(self, queue: DispatchQueue(label: "sample buffer delegate", attributes: [])) if captureSession.canAddOutput(videoOutput) { captureSession.addOutput(videoOutput) } self.videoPreviewLayer.setSessionWithNoConnection(self.captureSession) self.videoPreviewLayer.videoGravity = AVLayerVideoGravity.resizeAspect let cameraVideoPreviewLayerConnection = AVCaptureConnection(inputPort: self.videoDeviceInput.ports.first!, videoPreviewLayer: self.videoPreviewLayer); self.captureSession.addConnection(cameraVideoPreviewLayerConnection) self.captureSession.commitConfiguration() self.captureSession.startRunning()

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

A few versions of iOS ago, the stitching algorithm for panoramas was updated, which produces results that in my opinion look less good for what I'm using the panoramas for. I was exploring developing a custom panorama app but couldn't find the API for taking panoramic photos, much less stitching them. Is there an API in AVFoundation or elsewhere to use for capturing a panoramic photo and stitching it?

My app uses PHLivePhoto.request to generate live photos, but memory leaks if I use a custom targetSize. PHLivePhoto.request(withResourceFileURLs: [imageUrl, videoUrl], placeholderImage: nil, targetSize: targetSize, contentMode: .aspectFit) {[weak self] (livePhoto, info) in Change targetSize to CGSizeZero, problem resolved. PHLivePhoto.request(withResourceFileURLs: [imageUrl, videoUrl], placeholderImage: nil, targetSize: CGSizeZero, contentMode: .aspectFit) {[weak self] (livePhoto, info) in

WWDC23 Platform State of the Union mentioned that Volume shutter buttons to trigger the camera shutter is coming later this year. This was mentioned at 0:30:15. Would anyone know when this will be available?

Now I use AVFoundation framework to get the photo output, but the image aspect ratio is 4:3. But according to the Camera app in the iPhone 13 Pro, it has server image aspect ratio: 4:3, 16:9 and 1:1 when take the proraw image. So how can I get the 1:1, 16:9 aspect ratio proraw image? After I do some research, I find that no matter you use which kinds of camera in the iPhone 11, 12, 13, 14, 15 or Pro, the result image is always 4:3, 1:1 and 16:9 come from the 4:3 cropping. If it is true, how can I crop the proraw file without any data lossing? My developer environment: iPhone 13 Pro iOS 16.7 xcode 14.3.1 This is the session configuration code for the camera device configuration. session.beginConfiguration() /* Do not create an AVCaptureMovieFileOutput when setting up the session because Live Photo is not supported when AVCaptureMovieFileOutput is added to the session. */ session.sessionPreset = .photo // Add video input. do { var defaultVideoDevice: AVCaptureDevice? if let backCameraDevice = AVCaptureDevice.default(.builtInWideAngleCamera, for: .video, position: .back) { // If a rear dual camera is not available, default to the rear wide angle camera. defaultVideoDevice = backCameraDevice } else if let frontCameraDevice = AVCaptureDevice.default(.builtInWideAngleCamera, for: .video, position: .front) { // If the rear wide angle camera isn't available, default to the front wide angle camera. defaultVideoDevice = frontCameraDevice } guard let videoDevice = defaultVideoDevice else { print("Default video device is unavailable.") setupResult = .configurationFailed session.commitConfiguration() return } let videoDeviceInput = try AVCaptureDeviceInput(device: videoDevice) if session.canAddInput(videoDeviceInput) { session.addInput(videoDeviceInput) self.videoDeviceInput = videoDeviceInput } else { print("Couldn't add video device input to the session.") setupResult = .configurationFailed session.commitConfiguration() return } } catch { print("Couldn't create video device input: \(error)") setupResult = .configurationFailed session.commitConfiguration() return } // check the lens list let camerasOptions = videoDeviceDiscoverySession.devices var availableCameras: [AVCaptureDevice.DeviceType] = [] if camerasOptions.isEmpty { print("no camera devices") } else { for camera in camerasOptions { if camera.deviceType == .builtInUltraWideCamera || camera.deviceType == .builtInWideAngleCamera || camera.deviceType == .builtInTelephotoCamera { if !availableCameras.contains(camera.deviceType) { availableCameras.append(camera.deviceType) } } } } DispatchQueue.main.async { self.lensList = availableCameras } // Add the photo output. if session.canAddOutput(photoOutput) { session.addOutput(photoOutput) photoOutput.isHighResolutionCaptureEnabled = true photoOutput.maxPhotoQualityPrioritization = .quality print(photoOutput.isAppleProRAWSupported) // Use the Apple ProRAW format when the environment supports it. photoOutput.isAppleProRAWEnabled = photoOutput.isAppleProRAWSupported DispatchQueue.main.async { self.isSupportAppleProRaw = self.photoOutput.isAppleProRAWSupported } } else { print("Could not add photo output to the session") setupResult = .configurationFailed session.commitConfiguration() return } session.commitConfiguration()

Why, when I am recording and mixing videos from two cameras simultaneously using AVMultiCamPiP app as I guide, the nominalframerates of the videoAssetTracks I am recording do not have a fixed value (e.g. 30) but floats between 20-30 when the active format I am loading on both AVCaptureDevices supports that (e.g. 'vide'/'420v' 1920x1080, { 1- 30 fps},....) and I set min and max frame duration at 30fps (1,30).

We are developing an image classification iOS app where we use Tensor flow model. Prediction of Tensor flow model depends upon accuracy of image captured. We are facing issue with iPhone 14 pro versions. Images captured are blurry. As per this link, https://www.pcmag.com/news/apple-promises-fix-for-iphone-14-pro-camera-shake-bug Blurry issue is fixed by apple. But we are still facing this issue on iPhone 14 Pro versions. Our iOS version is above 16.2. We are also facing this issue on whatsApp (and other third party applications as well). Is there any official documentation on how to open camera on iPhone 14 pro programmatically? Note: When we use apple camera app this issue doesn’t exist. Is this hardware or software issue? Is this issue fixed on iPhone 15 version? Can you please guide us on this issue. Thanks Jay

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, 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.

Is it possible to access "From my mac" photos/PHAssetCollection through PhotoKit in iOS? "From my mac" photos/videos are media synced from a mac where iCloud Photos are turned off on the iOS device, like what we did in the ole' days before iCloud Photos. I have set up an iOS device with "From my mac" albums present in Photos.app, but in my own app I don't seem to be able to access those collections/photos through PhotoKit using all the defined PHAssetCollectionTypes. Are these directly synced photos simply not available through PhotoKit and you would have to revert to the deprecated ALAssetLibrary?

We found there high possibility of CameraSessionWasInterrupted exception in iOS17 beta5 any body knows why?

Environment: iOS 16 beta 2, beta 3. iPhone 11 Pro, 12 mini Steps to reproduce: Subscribe to Photo Library changes via PHPhotoLibraryChangeObserver, put some logs to track inserted/deleted objects: func photoLibraryDidChange(_ changeInstance: PHChange) { if let changeDetails = changes.changeDetails(for: allPhotosFetchResult) { for insertion in changeDetails.insertedObjects { print("🥶 INSERTED: ", insertion.localIdentifier) } for deletion in changeDetails.removedObjects { print("🥶 DELETED: ", deletion.localIdentifier) } } } Save a photo to camera roll with PHAssetCreationRequest Go to the Photo Library, delete the newly saved photo Come back to the app and watch the logs: 🥶 INSERTED:  903933C3-7B83-4212-8DF1-37C2AD3A923D/L0/001 🥶 DELETED:  39F673E7-C5AC-422C-8BAA-1BF865120BBF/L0/001 Expected result: localIdentifier of the saved and deleted asset is the same string in both logs. In fact: It's different. So it appears that either the localIdentifier of an asset gets changed after successful saving, or it's a bug in the Photos framework in iOS 16. I've checked - in iOS 15 it works fine (IDs in logs match).

For PHPickerViewController, we know we can perform simple filtering by var config = PHPickerConfiguration() config.filter = PHPickerFilter.images But, how about we only want to show images with format JPG & PNG, but excluding GIF? This is because our app doesn't support GIF. Is it possible to do so?

We are making application of ios. The application is for Disaster prevention in Japan. Because, Recentry in Japan has many Disaster in all season. We spplied to Local government in Japan and using general public and they are using well. One of the local government request to us, they want also supply to deaf person and help whe disaster occur. Local government already has disaster prevention broadcast but it is using loudspeaker. Then, when rains heavily, it can not hear to general public. And our application is from disaster prevention broadcast and forwarding to ios smartphone. It is helpfull to general public well. We are making new application it is not only prevention broadcast text but flashlight with iphone. But after making application, the flashlight is lighting only open our application. like beloe link. But, if Deaf person using it maybe he is not notice well. Our application is already has viblation function but Deaf person put his smartphone in his bag maybe I think he never noticed that Heavy rain and tsunami. Here is our application https://apps.apple.com/jp/app/cosmocast/id1247774270?mt=8 Here is application rule for flashlight. https://stackoverflow.com/questions/32136442/iphone-flashlight-not-working-while-app-is-in-background/32137434 I want help Deaf person and also senior citizens for Heavy rain and tsunami by our application. We'd like to make a flash light at the same time as the push notification arrived. Does anyone know a good way? Thank you and Best regards. Tomita.

I have a UICollectionView to display photos from a device's album with the Photos framework. The photos are correctly displayed, but if I scroll fast (like when you tape at the top of the screen to go to the top of the collectionView), I have some photos which are not at the good indexPath. I just need to scroll a bit to put the bad photo out of the screen, and everything go back in place.I clean the cell during prepareForReuse by canceling the current request.I presume it's a problem with the asynchronous request of PHImageManager, but I don't know how to avoid this problem. And I want to keet the asynchronous request to keep the collectionView smooth.Here some code :View Controller extension AlbumDetailViewController : UICollectionViewDataSource { func numberOfSectionsInCollectionView(collectionView: UICollectionView) -&gt; Int { return 1 } func collectionView(collectionView: UICollectionView, numberOfItemsInSection section: Int) -&gt; Int { return photoList.count } func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -&gt; UICollectionViewCell { let cell = collectionView.dequeueReusableCellWithReuseIdentifier("PhotoCell", forIndexPath: indexPath) as!
