Question

这是我用于在Visual Studio 2015社区中打开视频文件的代码。我调试它时遇到错误。打开的视频屏幕在几分之一秒后立即关闭。

#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;


}

它完美编译但是当我调试它时..它显示以下错误：

'OpenCV_try.exe' (Win32): Loaded 'C:\opencv\build\x64\vc12\bin\opencv_ffmpeg300_64.dll'. Module was built without symbols.
The thread 0x2dc0 has exited with code -1 (0xffffffff).
The thread 0x514 has exited with code -1 (0xffffffff).
The thread 0x2184 has exited with code -1 (0xffffffff).
The program '[1616] OpenCV_try.exe' has exited with code -1 (0xffffffff).

有人可以帮我解决错误吗？

Answer 1

这些都没有错误。 exited with code -1表示它在某处返回-1。看看它的位置：你的程序确实在if(!vid.read(frame))上返回-1。

在system("pause");之前设置return 0并阅读输出

无法使用openCV在Visual Studio中打开视频
