avcapturedevice

I am having difficult times, for something which I think ought to be simple. I just want to light the flash when taking a picture in my iOS app. And all I tried failed or works only 20 percent. Here is the code fired to light the flash up: // Here we have: captureDevice.hasFlash && captureDevice.isFlashModeSupported(.On) do {try captureDevice.lockForConfiguration() captureDevice.flashMode = .On captureDevice.unlockForConfiguration() } catch let error as NSError { print("captureDevice.lockForConfiguration FAILED") print(error.code) } I have tried several flavors of the code, by moving the 2

The simpler way to record a video on iOS is by setting a AVCaptureSession.sessionPreset . But that doesn't work for me since I want to control parameters like binning, stabilization (cinematic, standard, or none) and ISO. I find the format I want and assign it to activeFormat , but when I try to start recording, I get an error: Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[AVCaptureMovieFileOutput startRecordingToOutputFileURL:recordingDelegate:] No active/enabled connections' Here is my initialisation code: let device = AVCaptureDevice.defaultDevice(

I have a video capturing app and I want to be able to play background music while recording audio+video. I can accomplish this if I set the AVAudioSession category to PlayAndRecord in didFinishLaunchingWithOptions . However, this causes a glitch in the audio whenever the view with the camera enters or exits the foreground, and its apparently impossible to get rid of: https://forums.developer.apple.com/message/74778#74778 I can live with the glitch if it just happens when I start/stop recording video, but that means I need to change the AVAudioSession category from Ambient to PlayAndRecord when

I am playing with swift and an iPhone 7 Plus. I am working with builtInWideAngleCamera and builtInTelephotoCamera. This is great, even if i cannot get the 2 images simultaneously. I saw in apple documentation that AVCaptureDeviceType contains a builtInDualCamera entry. What is the purpose of this device in avfoundation, because we cannot do anything (zoom, depth effect) with apple API ? In other word, i cannot see the difference between builtInDualCamera and builtInWideAngleCamera when working with AVCaptureDeviceType, avcapturesession and stuff Thanks Duel-Camera options is to choose the

I want to pull frames from the live-feed of AVCaptureSession and I am using Apple's AVCam as a test case. Here is the link to AVCam: https://developer.apple.com/library/ios/samplecode/AVCam/Introduction/Intro.html I found that that captureOutput:didOutputSampleBuffer:fromConnection is NOT called and I would like to know why or what I am doing wrong. Here is what I have done: (1) I make the AVCamViewController a delegate @interface AVCamViewController () <AVCaptureFileOutputRecordingDelegate, AVCaptureVideoDataOutputSampleBufferDelegate> (2) I created an AVCaptureVideoDataOutput object and add

I have two view controllers. One is the root VC and contains the UI interface such as the record button. On this view controller, I also display the view of another VC at index 0. This view contains a AVCaptureVideoPreviewLayer. I would like my video camera to mimic the Apple video camera app, where the interface layout adjusts with the rotation, but the video preview layer does not. You can see how the recording timer (UILabel) in the stock video app disappears and reappears at the top depending on the orientation. Any idea how to do this? I found one suggestion that recommendeds adding the
