OpenCV iPhone相机，更改CV_CAP_PROP_IOS_DEVICE_ *无效

Question

我正在玩OpenCV2 + iPhone相机捕捉

self.capture = cvCreateCameraCapture(CV_CAP_ANY);
...   
IplImage * frame = cvQueryFrame(self.capture);

_

NSLog(@"CV_CAP_PROP_IOS_DEVICE_WHITEBALANCE = %f", cvGetCaptureProperty(self.capture ,CV_CAP_PROP_IOS_DEVICE_WHITEBALANCE));
NSLog(@"CV_CAP_PROP_IOS_DEVICE_TORCH = %f", cvGetCaptureProperty(self.capture ,CV_CAP_PROP_IOS_DEVICE_TORCH));
NSLog(@"CV_CAP_PROP_IOS_DEVICE_FOCUS = %f", cvGetCaptureProperty(self.capture ,CV_CAP_PROP_IOS_DEVICE_FOCUS));
NSLog(@"CV_CAP_PROP_IOS_DEVICE_FLASH = %f", cvGetCaptureProperty(self.capture ,CV_CAP_PROP_IOS_DEVICE_FLASH));
NSLog(@"CV_CAP_PROP_IOS_DEVICE_EXPOSURE = %f", cvGetCaptureProperty(self.capture, CV_CAP_PROP_IOS_DEVICE_EXPOSURE));

但是，更改任何CV_CAP_PROP_IOS_DEVICE_ *没有任何效果，我发现大多数都可以更改为0,1,2（在使用cvGetCaptureProperty（）查询值后）

但它没有效果：（

任何想法？

iOS OpenCV端口仍为in development - 请耐心等待几个月以获得更好的支持。

或者，更好的是，只需获取源代码，阅读它们，实现这些功能并将其作为补丁推回。您将获得荣耀，感谢和宝贵的开源开发经验。
