I tried to play a video using OpenCV-2.4.7 in Visual Studio 2010, Win 7

Code is as follow-

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

using namespace cv;

int main( int argc, char** argv ) {
    cvNamedWindow( "Window", CV_WINDOW_AUTOSIZE );
    CvCapture* capture = cvCreateFileCapture( "C:/Users/17/Desktop/Wildlife.avi" );
    IplImage* frame;

    while(1) {
        frame = cvQueryFrame( capture );
        if( !frame ) break;
        cvShowImage( "Window", frame );
        char c = cvWaitKey(33);
        if( c == 27 ) break;
    }
    cvReleaseCapture( &capture );
    cvDestroyWindow( "Window" );
}

Debugs is fine but on running, a waring window opens saying "The program can't start because libiconv-2.dll is missing from your computer".

I tried to download libiconv-2.dll into system package then it showed the error "C:\Windows\System32\libiconv-2.dll', Binary was not built with debug information".

Is there any possible missing setting?? what should be done to run this code?

  • I am confused as to why your program is trying to link to libiconv in the first place; it is a GNU dll and it's required only when you are using the gcc compiler. Are you project setting correct.? Have you used CMake to generate the project files? – scap3y Dec 07 '13 at 18:53

It's an issue with opencv_ffmpeg247.dll in the latest release (2.4.7) as described here

I'm having the same issue, though with the fix earmarked for 2.4.8 I'd suggest either installing an earlier version (2.4.6) or using the latest copy from the repo here

  • I installed version 2.4.6 and now having this error- C:\opencv\build\x86\mingw\bin\opencv_ffmpeg246.dll', Binary was not built with debug information. – Gaurav Sharma Dec 08 '13 at 08:54
