Answer 1

I think the problem you're encountering is that your "for" loop never ends; therefore, cvReleaseVideoWriter(&writer); and cvReleaseCapture(&input); never get called. Try something like for(int i=0; i<200; i++) and see if you end up with a working video.

Often video is written to a temporary files before being finalized on disk. If your file isn't finalized, there won't be anything to see.

Hope that helps.
