avcapturesession

I'm using Apple's example code for AVCaptureSession, and the UIImage that gets created is completely blank. This only happens on the iPhone 3G, along with a unique error that shows up on console that says - Error: CGDataProviderCreateWithCopyOfData: vm_copy failed: status 2. I've researched the error online and found this StackOverflow answer , and it gets rid of the error...but the image is still blank. Has anyone else experienced this and know how to fix it? Thanks in advance. My Code - CVImageBufferRef imageBuffer = CMSampleBufferGetImageBuffer(sampleBuffer); CVPixelBufferLockBaseAddress

I created an AVCaptureSession and attached to it the front facing camera do { try captureSession.addInput(AVCaptureDeviceInput(device: captureDevice)) }catch{print("err")} Now I want to start and stop recording on touche events. How do I do this? override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) { print("touch") //Start Recording } override func touchesEnded(touches: Set<UITouch>, withEvent event: UIEvent?) { print("release"); //End Recording and Save } You didn't mention if you're using AVCaptureMovieFileOutput or AVCaptureVideoDataOutput as an output for your

I have an issue with the delegate method didOutputSampleBuffer:(CMSampleBufferRef)sampleBuffer fromConnection:(AVCaptureConnection *)connection of AVCaptureOutput . It stops getting called within a second or two when I'm adding the sampleBuffer to a CFArray . If I remove the CFArray code, the delegate method continues to get called so I have no idea why the CFArray code is causing it to stop. I'd appreciate any help. @property CFMutableArrayRef sampleBufferArray; - (void)captureOutput:(AVCaptureOutput *)captureOutput didOutputSampleBuffer:(CMSampleBufferRef)sampleBuffer fromConnection:

I have a working barcode scanner code. When I click the openCamera button, first time everything is good. When I click the closeCamera button, good, but if I click again the openCamera button gives a fatal error. Code and error are below. In fact, is it possible to toggle camera view with one button? // Barcode Camera Properties let captureSession = AVCaptureSession() var captureDevice:AVCaptureDevice? var captureLayer:AVCaptureVideoPreviewLayer? override func viewDidLoad() { super.viewDidLoad() self.cameraView.alpha = 0 } @IBAction func closeCamera(sender: AnyObject) { self.captureLayer!

I'm trying to capture audio, using the method in this question ; with AVCaptureSession and AVCaptureAudioDataOutput. This seems to work fine with 1 inconvenience: it doesn't work in the simulator. Both AVAudioRecorder, and the good old SpeakHere demo app, work fine in the simulator, using the internal microphone on my MacBook Pro. Problem is that [AVCaptureDevice defaultDeviceWithMediaType:AVMediaTypeAudio] gives null in the simulator, so subsequent code fails with the message (when it tries to add null as input to the AVCaptureSession): *** Terminating app due to uncaught exception
