avcapturedevice

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 am developing video streaming application, in which i need to capture front camera video frame and encode then transfer to other end, a typical flow is like this AVCaptureSession -> AVCaptureDeviceInput -> AVCaptureVideoDataOutput -> capture frame --> encode frame --> send frame to other end, it works fine, i have setup the kCVPixelFormatType_420YpCbCr8BiPlanarVideoRange as a frame format. also preview layer being used to show the preview, the problem comes when device orientation gets changes, if device moved from portrait to landscape, then on the other end frames gets rotate by 90, i was

How can I do face detection in realtime just as "Camera" does? like white round shape around and over the face. I use AVCapturSession . I found that the image I saved for facial detection.

I'm using the following method to set point of focus since iOS 4: - (void) focusAtPoint:(CGPoint)point { AVCaptureDevice *device = [[self captureInput] device]; NSError *error; if ([device isFocusModeSupported:AVCaptureFocusModeAutoFocus] && [device isFocusPointOfInterestSupported]) { if ([device lockForConfiguration:&error]) { [device setFocusPointOfInterest:point]; [device setFocusMode:AVCaptureFocusModeAutoFocus]; [device unlockForConfiguration]; } else { NSLog(@"Error: %@", error); } } } On iOS 4 devices this works without any problems. But on iOS 5 the live camera feed freezes and after

I was able to capture video frames from the camera using AVCaptureSession according to http://developer.apple.com/iphone/library/qa/qa2010/qa1702.html . However, it seems that AVCaptureScreen captures frames from the camera without showing the camera stream on the screen. I would like to also show camera stream just like in UIImagePicker so that the user knows that the camera is being turned on and sees what the camera is pointed at. Any help or pointer would be appreciated! AVCaptureVideoPreviewLayer is exactly what you're looking for. The code fragment Apple uses to demonstrate how to use it
