Opencv error: (parameter or structure field)) unrecognized or unsupported array type in functon 'cvgetmat‘

1. Error message

2. Code

#include <iostream>
#include <libavutil/avutil.h>
#include <opencv2/highgui.hpp>
#include <opencv4/opencv2/imgproc.hpp>
main()
{
    cv::VideoCapture videoshow;
    cv::Mat image;
    videoshow.open("/home/lfh/ picture /vedio_test.avi");
    cv::namedWindow(" Read screen display ");
    while(1)
    {
        videoshow.read(image);
        cv::imshow(" Read screen display ", image);
        waitKey(20);
    }
    videoshow.~VideoCapture();
    return 0;
}

3. Reason and modification
The problem lies in the loop ,while(1) It means to always execute the code in the loop body , But the length of video file is limited , So when the video is finished, something goes wrong . Change the loop body to

while(videoshow.read(image))
    {
        cv::imshow(" Read screen display ", image);
        waitKey(20);
    }

that will do . Because if videoshow.read(image) Data can also be read , Returns the 1
