Question

I need to write a small software that will show video.
I don’t know any thing about graphics at C.

What classes are there?
Please point me to a place to start from.

Thanks,
Nahum

Another simple library to use to display video is OpenCV (cross-platform):

int main(int argc, char** argv) 
{
    cvNamedWindow("xsample", CV_WINDOW_AUTOSIZE);

    CvCapture* capture = cvCreateFileCapture("movie.avi");
    if (!capture)
    {
      printf("!!! cvCreateFileCapture didn't found the file !!!\n");
      return -1; 
    }

    IplImage* frame;
    while(1) 
    {
        frame = cvQueryFrame( capture );
        if (!frame) 
            break;

        cvShowImage( "xsample", frame );

        char c = cvWaitKey(33);
        if (c == 27) 
            break; // ESC was pressed
    }

    cvReleaseCapture(&capture);
    cvDestroyWindow("xsample");

    return 0;
}

And that’s it. However, you won’t be able to play sound with OpenCV, just video. But if you are looking for a workaround on that, here is a little something I wrote some time ago using OpenCV and FFmpeg.
