Unknown type 'CvVideoCamera'
I am trying to use OpenCV to process video feed in an Swift iOS app.
I read that the best way to do this is with the CvVideoCamera class in an objective-c wrapper.
When I try to declare a CvVideoCamera object or pointer I get the error Unkown type 'CvVideoCamera'
Here is my code
#import <UIKit/UIKit.h>
@interface ViewController : UIViewController{
CvVideoCamera videoCamera;
cv::Mat src;
}
@end
Here is my prefix header
#ifndef PrefixHeader_pch
#define PrefixHeader_pch
#import <Availability.h>
#ifndef __IPHONE_4_0
#warning "This project uses features only available in iOS SDK 4.0 and later."
#endif
#ifdef __cplusplus
#include <opencv2/opencv.hpp>
#include <opencv2/imgcodecs/ios.h>
#endif
#ifdef __OBJC__
#import <UIKit/UIKit.h>
#import <Foundation/Foundation.h>
#endif
#endif /* PrefixHeader_pch */
I know that opencv is being included in the project because when I remove the line where I declare a CvVideoCamera
The code builds with no errors, even though I declare a Mat
object.
I tried using the cv
scope in front of CvVideoCamera, When I do that I get and error No type named CvVideoCapture in namespace cv
I have also tried putting the CvVideoCamera declaration in the implementation instead or the interface, changing the .m files to .mm, and declaring a pointer instead of an object;I still get the same errors.
When I look in the 0pencv2/imgcodecs/ios.h file, this is what I find
#import <UIKit/UIKit.h>
#import <Accelerate/Accelerate.h>
#import <AVFoundation/AVFoundation.h>
#import <ImageIO/ImageIO.h>
#include "opencv2/core/core.hpp"
//! @addtogroup imgcodecs_ios
//! @{
UIImage* MatToUIImage(const cv::Mat& image);
void UIImageToMat(const UIImage* image,
cv::Mat& m, bool alphaExist = false);
//! @}
There is nothing in there about CvVideoCamera, which leads me to believe I may be using the wrong include file, but everything I look up says that that is the right one to include
Any help would be appreciated, Thank You
You got your import for it?
@Tetragramm I think that's been replaced by
#include <opencv2/imgcodecs/ios.h>
, it says "cap_ios.h" not foundMm, no. I definitely see a cap_ios.h in my directory. In the videoio module. You may need to go opencv2/videoio/cap_ios.h
