在顯示opencv中的視頻時出錯

#include <cv.h> 
#include <highgui.h> 

int main(int argc,char** argv[]) 
{ 

     cvNamedWindow("video",CV_WINDOW_AUTOSIZE); 
    CvCapture* capture = cvCreateFileCapture("Input_1.avi"); 
    if (!capture) 
     { 
      std::cout << "!!! cvCreateFileCapture didn't found the file !!!\n"; 
      return -1; 
      } 
    IplImage* frame; 


    while(1) 
    { 
     frame = cvQueryFrame(capture); 
     if (!frame) 
      break; 
     cvShowImage("video",frame); 
     char c=cvWaitKey(40); 
     if (c==27) 
      break; 
    } 
    cvReleaseCapture(&capture); 
    cvDestroyWindow("video"); 
}

這是我試過的代碼。我收到警告，只要我建立的解決方案如下：在顯示opencv中的視頻時出錯

Hello_World.cpp 

1>c:\opencv231\include\opencv2\flann\logger.h(66): warning C4996: 'fopen': This function or variable may be unsafe. Consider using fopen_s instead. To disable deprecation, use _CRT_SECURE_NO_WARNINGS. See online help for details.

========== Build: 1 succeeded, 0 failed, 0 up-to-date, 0 skipped ==========

即使我運行，我不能看到視頻流！聞一按ESC鍵退出，我甲肝類似

loaded , unloaded dlls ,cannot find or open PDB file , 
thread has exited with code 0 , 
Native has exited with code 0 .

請幫助我。我只是opencv的初學者。謝謝。

檢查您的計算機上是否有opencv_ffmpeg231.dll。如果沒有，this後有一個解決方案。
