    I thought all the fps, tbr, tbn and tbc are the same, so what is the problem ??
It is off several seconds from the total sum of each individual file !

    


  • Possible bug in OpenCV2.4 capturing frames from video

    23 septembre 2013, par Jav_Rock

    Could it be that there is a bug in OpenCV2.4 highgui for capturing frames from video in windows ?

    I installed both the precompiled libraries, the ones compiled by me, I can compile everything perfectly and I can run my programs if

    they are image based. The problem is only for videos. OpenCV crashes in this function always :

     virtual IplImage* retrieveFrame(int)
    
    {
    
        unsigned char* data = 0;
    
        int step=0, width=0, height=0, cn=0;
    

    
        if(!ffmpegCapture ||
    
           !icvRetrieveFrame_FFMPEG_p(ffmpegCapture,&data,&step,&width,&height,&cn)) <-------CRASHES HERE
    
           return 0;
    
        cvInitImageHeader(&frame, cvSize(width, height), 8, cn);
    
        cvSetData(&frame, data, step);
    
        return &frame;
    
    }

    This is inside the class cap_ffmpeg.cpp and is called by VideoCapture.

    I tried versions 2.4.2 and 2.4.9. My programes were working finde with opencv2

    More information

    • Windows 7

    • Build the projects with cmake (important as it could be that cmake is not building/finding the right codecs)

    • VisualStudio 9 2008

    • OpenCV 2.4.2

    EDIT

    It looks like it is actually a bug, so, how can I solve this problem and change my code to be able to read avi files ?
