根据这种技术最适合将iPhone视频摄像机数据直播到计算机？可以从iphone相机获取压缩数据,但正如我在AVFoundation参考中读到的那样,你只能得到未压缩的数据.

所以问题是:

1)如何从iPhone的相机获取压缩帧和音频？

2)用ffmpeg的API编码未压缩的帧对于实时流是否足够快？

任何帮助将非常感激.

谢谢.

我正在录制来自ipad应用程序的视频,我希望该视频可以保存在文档文件夹中,或者直接我们可以将其上传到服务器.我在文档中存储音频文件但是如何保存视频文件.我使用以下代码进行录制视频.

谢谢.

  UIImagePickerController *picker = [[UIImagePickerController alloc] init];
  picker.delegate = self;

  if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera])
  {
    NSArray *mediaTypes = [NSArray arrayWithObject:(NSString*)kUTTypeMovie];
    picker.mediaTypes = mediaTypes ;
    picker.sourceType = UIImagePickerControllerSourceTypeCamera;
    picker.cameraCaptureMode = UIImagePickerControllerCameraCaptureModeVideo ;

    [self presentModalViewController:picker animated:NO];

    [picker release];
}
  else
    {

UIAlertView *alt=[[UIAlertView alloc]initWithTitle:@"Error" message:@" Camera Facility is not available with this Device" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil, nil];
    [alt show];
    [alt release];
    }
