I'm trying to use open cv (2.4.9) video support from within C++. However, when I try to open a video file with cv::VideoCapture I get

warning: Error opening file (/tmp/opencv-mLsrDm/opencv-2.4.9/modules/highgui/src/cap_ffmpeg_impl.hpp:545)
WARNING: Couldn't read movie file 11:28:39.mp4

Using cv2.VideoCapture from within python on the same file works. The python wrappers are from the same build of opencv so I'm a bit perplexed.

Mac os 10.9.4. OpenCV is built with ffmpeg (but no quicktime) via homebrew.

I'm linking against all the libraries that the the python cv2.so is linked against.

Any ideas? Thanks.

It turned out that ffmpeg doesn't like file names like 11:28:39.mp4. Renaming the file to test.mp4 makes things work.
