C++ 无法使用openCV在Visual Studio中打开视频

这是我用来在Visual Studio 2015社区中打开视频文件的代码。我调试它们时会出错。打开的视频屏幕在几秒钟内打开后立即关闭

#include <opencv2/highgui/highgui.hpp>                                              
#include <opencv2/imgproc/imgproc.hpp>
#include <opencv2/core/core.hpp>
#include <opencv2/imgproc/imgproc_c.h>
//#include "opencv2/contrib/contrib.hpp"
#include <iostream>                                                                 
#include <stdio.h>
#include <stdlib.h>
#include <math.h>

using namespace cv;
using namespace std;

   int main(int argc, char **argv)
{
Mat frame;
 VideoCapture vid("D:\\Projects\\Visual Tries\\OpenCV_try\\OpenCV_try\\Dinner.avi");
if (!vid.isOpened())
    return -1;
int fps = (int)vid.get(CAP_PROP_FPS);
namedWindow("Showing Film");
while (1)
{
    if (!vid.read(frame))
        break;
    imshow("Showing Film", frame);
    if (waitKey(1000 / fps) >= 0)
        break;
}
waitKey();
return 0;


}

有人能帮我解决这个错误吗？

这些都不是错误<代码>与代码-1一起退出意味着它在某处返回了-1。看看它在哪里：如果（！vid.read（frame）），程序确实会在

上返回-1

制作一个
系统（“暂停”）返回0
并读取输出之前
这些都不是错误。您的文件未打开，因此程序返回-1并退出。这是一个有效的路径：“D:\\Projects\\Visual Tries\\OpenCV\u try\\OpenCV\u try\\Dinner.avi”路径中是否确实有2个OpenCV\u try？您的程序是否有权访问ooencb\u ffmpeg dll文件？例如，但它位于工作目录或path变量中。您可以尝试使用不同编解码器的不同视频文件和/或为我们上载视频文件吗？
