OpenCV - RTSP stream not opening

Question

I have a RTPS streaming camera. The stream works fine when I test it with VLC:

vlc -vvv rtsp://192.168.0.23:554/stream

However with openCV it does not open:

cv::VideoCapture capture; bool ok = capture.open("rtsp://192.168.0.23:554/stream");

returns false.

What can be the reason?

I had a similar problem. In my case the dll starts with "opencv_ffmpeg" was missing in the run path.
