在iOS7中AVCaptureMovieFileOutput在UIImagePickerController中用于将视频帧从相机附加到它的临时。mov文件?
. mov文件被创建在一个临时的位置，然后进一步附加到底层AVCaptureMovieFileOutput对象，当用户在iOS7中通过UIImagePickerController录制视频时。
我尝试使用符号断点和方法混合来精确定位以下问题之一(但没有成功)。有可能我错过了实际使用的流类型或类(或者我的断点设置不正确):
- NSWriteStream
- CFWriteStream
- 从它派生出子类)NSStream
- fstream
- ofstream 上ostream
- iostream
- NSFileHandle posix文件描述符
- AVAssetWriter
- AVAssertExportSession
- ALAssetClass
- ALAssetLibrary
这是我用来呈现UIImagePickerViewController来录制视频的:
#import <MobileCoreServices/MobileCoreServices.h>
-(void)startPicker{
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
[picker setSourceType:UIImagePickerControllerSourceTypeCamera];
[picker setAllowsEditing:NO];
[picker setDelegate:self];
[picker setMediaTypes:@[(NSString*)kUTTypeMovie]];
[self presentViewController:picker animated:YES completion:nil];
}
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
[picker dismissViewControllerAnimated:YES completion:nil];
if (info)
{
NSURL* fileURL = [info objectForKey:UIImagePickerControllerMediaURL];
NSLog(@"%@", fileURL.path);
}
}
- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker {
[picker dismissViewControllerAnimated:YES completion:nil];
}
我真的需要特定的流类型和一种方法，我可以证明它正在被iOS7使用。很多谢谢!
你可以证明的方法?我不确定，但苹果更喜欢m3u8流媒体
