It compiles, but cvCreateFileCapture always returns null with the video I am sending it. I checked and the video is definitely present (I used absolute path). I made sure FFMPEG and libav-tools were properly installed like many other forums suggested. Even when I would uninstall and reinstall OpenCV, I would see that the CMake configuration output recognizes FFMPEG. Unfortunately, I do not remember the version of OpenCV I had before when it worked. How do I get this working? Thanks!
