Webcam Streaming is mirrored using OpenCV 3.0 + Visual Studio 2013 - c++

Question

Every time i compile this code the webcam streaming is mirrored like I lift up my right hand and it appears like if it was my left hand on the screen instead and after a couple of re-compiling an error message appeared and the code never worked again.
The error:
Unhandled exception at 0x00007FFB3C6DA1C8 in Camera.exe: Microsoft C++ exception: cv::Exception at memory location 0x000000D18AD5F610.
And no other option left except to break the process.
The code:
#include <opencv2/highgui/highgui.hpp>
#include <opencv\cv.h>
using namespace cv;
int main(){
Mat image;
VideoCapture cap;
cap.open(1);
namedWindow("Window", 1);
while (1){
cap >> image;
imshow("window", image);
waitKey(33);
}
}
I don't know if something wrong with my code I've just started learning opencv !

#include <opencv2/highgui/highgui.hpp>
#include <opencv\cv.h>
using namespace cv;
int main(){
Mat image;
VideoCapture cap;
cap.open(1);
namedWindow("Window", 1);
while (1){
cap >> image;
flip(image,image,1)
imshow("window", image);
waitKey(33);
}
}
just Flip the image horizontally that will do Find More Here

Answer 2

There is nothing wrong when your image is mirrored on the vertical (/x) axis (I guess in your example you are using a built-in (laptop) webcam).
A (very) simple code for capturing and showing your image could be the following:
// imgcap in opencv3
#include "opencv2/highgui.hpp"
#include "opencv2/videoio.hpp"
int main() {
cv::VideoCapture cap(0); // camera 0
cv::Mat img;
while(true) {
cap >> img;
cv::flip(img,img,1);
cv::imshow("live view", img);
cv::waitKey(1);
}
return 0;
}
When using OpenCV 3 you should include headers like:
#include <opencv2/highgui.hpp>
