Did you use the tutorial on this link to open a Video?

Furthermore, be sure that all the codecs are somehow installed on your system. You could try to manually download and install ffmpeg here

Ok basically a lot of problems which were ffmpeg related are solved in the new version 2.4.5. So first download this one and see if your problem gets fixed. A second approach could be to download the latest ffmpeg libraries for your system yourself and replacing the ffmpeg libraries inside openCV folder structure. Then build your OpenCV based on this new library.

First try the newer version. Else go to, download them and then look for a guide on the internet on how to build openCV yourself with specified ffmpeg version.
