OpenCV play video

During school days when i use OpenCV 1.1-2.0 for my final year project,

I had a hard time trying to capture video frame from .avi files.

I ran into codec issues having to convert my video dataset before i can capture

via OpenCV.

With the following code snippets below i am able to play .avi,.mpg and wmv files!

#include "highgui.h"
int main( int argc, char** argv ) {
  
    //Some validation can be included here for argv
    if( argc<2 ) return 1;
    CvCapture* capture = cvCreateFileCapture( argv[1] );
    if( !capture ) return 1;   
     /* get fps, needed to set the delay */
    int fps = ( int )cvGetCaptureProperty( capture, CV_CAP_PROP_FPS );
    IplImage* frame;
    cvNamedWindow( "video", CV_WINDOW_AUTOSIZE );
    while(1) {
        frame = cvQueryFrame( capture );
        if( !frame ) break;
        cvShowImage( "video", frame );
        char c = cvWaitKey( 1000 / fps );
        if( c == 27 ) break;
    }
    cvReleaseCapture( &capture );
    cvDestroyWindow( "video" );
    return 0;
}
