I built OpenCV (with mingw 4.9.2 @ Win7Prof64) with CMake switches for WITH_FFMPEG and WITH_DSHOW turned on. When I access a movie file with
VideoCapture (fileName)
works fine (it uses ffmpeg backend then).
But
VideoCapture (fileName, cv::CAP_DSHOW)
doesn't work (isOpened() returns false).
What is missing/ what do I do wrong? Are there any kind of dshow stubs/ libs/ dlls needed?
