opencv c++ 创建窗口失败

问题遇到的现象和发生背景

opencv c++ 创建control窗口失败，只能调出摄像头

运行结果及报错内容

无法创建control窗口

我的解答思路和尝试过的方法
我想要达到的结果

大概看了一下如果按你说逻辑没问题，那就是你创建了窗口"Control"但是自始至终你也没用他而是另外又重新在其他窗口显示，你不imshow一下人家当然不给你看了；

 namedWindow("Control", CV_WINDOW_AUTOSIZE); //create a window called "Control"

        imshow("Thresholded Image", imgThresholded); //show the thresholded image
        imshow("Original", imgOriginal); //show the original image

#include "opencv2/highgui/highgui_c.h"
#include "opencv2/imgproc/imgproc_c.h"
#include<opencv2/opencv.hpp>
#include <iostream>

using namespace cv;
using namespace std;

int main(int argc, char* argv[])
{
    VideoCapture cap(0); // open the video camera no. 0

    if (!cap.isOpened())  // if not success, exit program
    {
        cout << "Cannot open the video cam" << endl;
        return -1;
    }

   double dWidth = cap.get(CV_CAP_PROP_FRAME_WIDTH); //get the width of frames of the video
   double dHeight = cap.get(CV_CAP_PROP_FRAME_HEIGHT); //get the height of frames of the video

    cout << "Frame size : " << dWidth << " x " << dHeight << endl;

    namedWindow("MyVideo",CV_WINDOW_AUTOSIZE); //create a window called "MyVideo"

    Mat frame;
cap.read(frame);

while (1)
{

    bool bSuccess = cap.read(frame); // read a new frame from video

     if (!bSuccess) //if not success, break loop
    {
         cout << "Cannot read a frame from video stream" << endl;
         break;
    }

    imshow("MyVideo", frame); //show the frame in "MyVideo" window

    if (waitKey(30) == 27) //wait for 'esc' key press for 30ms. If 'esc' key is pressed, break loop
   {
        cout << "esc key is pressed by user" << endl;
        break;
   }
}
return 0;

}
