iPhoneを使用して5分間ビデオをキャプチャしてから、キャプチャしたビデオをトリミングしてバイナリデータ形式で保存する必要があります。誰かがこれまでにそれをしたことがあるなら、私がそうするのを手伝ってください。
その画像のようにhttp://www.askdavetaylor.com/3-blog-pics/apple-iphone-video-editing-4.png
- (BOOL) startCameraControllerFromViewController: (UIViewController*) controller
usingDelegate: (id <UIImagePickerControllerDelegate, UINavigationControllerDelegate>) delegate {
NSLog(@"Camera Working");
if (([UIImagePickerController isSourceTypeAvailable:
UIImagePickerControllerSourceTypeCamera] == NO)
|| (delegate == nil)
|| (controller == nil))
return NO;
cameraUI = [[UIImagePickerController alloc] init];
cameraUI.mediaTypes = [[NSArray alloc] initWithObjects: (NSString *) kUTTypeMovie, nil];
cameraUI.sourceType = UIImagePickerControllerSourceTypeCamera;
// Displays a control that allows the user to choose picture or
// movie capture, if both are available: video and image capturing
//cameraUI.mediaTypes = [UIImagePickerController availableMediaTypesForSourceType:UIImagePickerControllerSourceTypeCamera];
// Hides the controls for moving & scaling pictures, or for
// trimming movies. To instead show the controls, use YES.
cameraUI.videoMaximumDuration = 300; // 5x60 sec
cameraUI.allowsEditing = YES;
cameraUI.delegate = delegate;
[controller presentModalViewController: cameraUI animated: YES];
return YES;
}
