Capture video and images to iPhone

I am using ImagePickerController to capture video. I also need to save the video as an image.

So, I chose AVCaptureSession to capture images. I can not start AVCaptureSession, as well as ImagePickerController. Therefore, I need to provide ImagePickerController as an input to AVCaptureSession.

But I do not know how to do this. Please help me .. and ask me the right way.

I had the same problem. I worked on the image and video and used the code below to capture the image:

- (void) snapImage: (id) sendern { UIImagePickerController *ipc = [[UIImagePickerController alloc] init]; ipc.sourceType = UIImagePickerControllerSourceTypeCamera; ipc.delegate = self; ipc.allowsImageEditing = YES; [self presentModalViewController:ipc animated:YES]; }

And for the record the video I used the code below:

 - (void) recordVideo: (id) sender { UIImagePickerController *ipc = [[UIImagePickerController alloc] init]; ipc.sourceType = UIImagePickerControllerSourceTypeCamera; ipc.delegate = self; ipc.allowsEditing = YES; ipc.videoQuality = UIImagePickerControllerQualityTypeMedium; ipc.videoMaximumDuration = 30.0f; // 30 seconds ipc.mediaTypes = [NSArray arrayWithObject:@"public.movie"]; // ipc.mediaTypes = [NSArray arrayWithObjects:@"public.movie", @"public.image", nil]; [self presentModalViewController:ipc animated:YES]; } ) sender - (void) recordVideo: (id) sender { UIImagePickerController *ipc = [[UIImagePickerController alloc] init]; ipc.sourceType = UIImagePickerControllerSourceTypeCamera; ipc.delegate = self; ipc.allowsEditing = YES; ipc.videoQuality = UIImagePickerControllerQualityTypeMedium; ipc.videoMaximumDuration = 30.0f; // 30 seconds ipc.mediaTypes = [NSArray arrayWithObject:@"public.movie"]; // ipc.mediaTypes = [NSArray arrayWithObjects:@"public.movie", @"public.image", nil]; [self presentModalViewController:ipc animated:YES]; } "public.movie", @ "public.image", nil]; - (void) recordVideo: (id) sender { UIImagePickerController *ipc = [[UIImagePickerController alloc] init]; ipc.sourceType = UIImagePickerControllerSourceTypeCamera; ipc.delegate = self; ipc.allowsEditing = YES; ipc.videoQuality = UIImagePickerControllerQualityTypeMedium; ipc.videoMaximumDuration = 30.0f; // 30 seconds ipc.mediaTypes = [NSArray arrayWithObject:@"public.movie"]; // ipc.mediaTypes = [NSArray arrayWithObjects:@"public.movie", @"public.image", nil]; [self presentModalViewController:ipc animated:YES]; } ]; - (void) recordVideo: (id) sender { UIImagePickerController *ipc = [[UIImagePickerController alloc] init]; ipc.sourceType = UIImagePickerControllerSourceTypeCamera; ipc.delegate = self; ipc.allowsEditing = YES; ipc.videoQuality = UIImagePickerControllerQualityTypeMedium; ipc.videoMaximumDuration = 30.0f; // 30 seconds ipc.mediaTypes = [NSArray arrayWithObject:@"public.movie"]; // ipc.mediaTypes = [NSArray arrayWithObjects:@"public.movie", @"public.image", nil]; [self presentModalViewController:ipc animated:YES]; }

Hope both code snippets help you.

Apple docs and sample code related to AVFoundation have several errors. See iOS 4: make photos with a live preview using AVFoundation for code that actually captures the image of the preview in real time.
