avcam

I am using the AVCam example App from Apple. This example uses AVFoundation in order to show video on a view. I am trying to make from the AVCam a landscape App with no luck. When screen orientation changes the video is shown rotated on the view. Is there a way of handling this problem? Samssonart When you create your preview layer: captureVideoPreviewLayer.orientation = UIInterfaceOrientationLandscapeLeft; And the methods to manage rotations: -(void)willAnimateRotationToInterfaceOrientation: (UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration { [CATransaction

I used the below code for focusing the iphone camera. But it is not working. I take this code from the AVCam sample code of Apple. Am I doing anything wrong? Is there any method to detect if the iPhone did focussing? -(void) focusAtPoint:(CGPoint)point { AVCaptureDevice *device = [AVCaptureDevice defaultDeviceWithMediaType:AVMediaTypeVideo];; if (device != nil) { if ([device isFocusPointOfInterestSupported] && [device isFocusModeSupported:AVCaptureFocusModeAutoFocus]) { NSError *error; if ([device lockForConfiguration:&error]) { [device setFocusPointOfInterest:point]; [device setFocusMode

I've integrated AVCam in my iOS app. The problem is in iPhone 4 the preview frame isn't fullscreen, it has empty side borders... How can I solve this? Thanks. You need to use the videoGravity property of the AVCaptureVideoPreviewLayer . Take a look to the doc . You need to use: AVLayerVideoGravityResizeAspectFill Edit: Based on that the solution founded by the asker is: - (void)setSession:(AVCaptureSession *)session { ((AVPlayerLayer *)[self layer]).videoGravity = AVLayerVideoGravityResizeAspectFill; ((AVPlayerLayer *)[self layer]).bounds = ((AVPlayerLayer *)[self layer]).bounds; [

I'm reading this tutorial on getting pixel data from the iPhone camera. While I have no issue running and using this code, I need to take the output of the camera data (which comes in BGRA) and convert it to ARGB so that I can use it with an external library. How do I do this? If you're on iOS 5.0, you can use vImage within the Accelerate framework to do a NEON-optimized color component swap using code like the following (drawn from Apple's WebCore source code ): vImage_Buffer src; src.height = height; src.width = width; src.rowBytes = srcBytesPerRow; src.data = srcRows; vImage_Buffer dest;

The Apple docs seem to indicate that while recording video to a file, the app can change the URL on the fly with no problem. But I'm seeing a problem. When I try this, the recording delegate gets called with an error... The operation couldn’t be completed. (OSStatus error -12780.) Info dictionary is: { AVErrorRecordingSuccessfullyFinishedKey = 0; } (funky single quote in "couldn't" comes from logging [error localizedDescription]) Here's the code, which is basically tweaks to WWDC10 AVCam sample: 1) Start recording. Start timer to change the output URL every few seconds - (void)

I would like to capture video from device’s back camera directly to ProRes codec, now that .proRes422 and .proRes4444 are available as AVVideoCodecType options in iOS 11. But I receive an error that recording is: unsupported given the current configuration On both iPhone X and second generation iPad Pro, when trying to capture video with the following code: movieFileOutput.setOutputSettings([AVVideoCodecKey: AVVideoCodecType.proRes422], for: movieFileOutputConnection!) If this approach is wrong, can the captured video be encoded by using AVCaptureVideoDataOutput alongside AVAssetWriter ? I
