I would like to use video datasets to test my program, but unfortunately it does not work.

How do I encode them for the current version of opencv?

PS: It seems to be a problem with cmake (OpenCV examples work but own project doesn't). I am using the tutorial CMakeList.txt that does not compile including the codecs. Can you give me any pointers on how to correctly do this?

The easiest way is to transcode the video with any available tool (mplayer, VirtualDub, etc...)

I am running out of ideas... are there any fool-proof video samples I could try? Maybe it's a problem with the code.

Our test videos are located in opencv_extra repository. For example you can test on big_buck_bunny.avi from

Do you use binary OpenCV package or you compiled OpenCV?

This is solved, but I am not allowed to close the question yet... It didn't work so I recompiled but forgot to "make install" -_- Everything works fine now...
