OpenCV cv::Mat、imshow()、cv::VideoCapture 在运行时不工作

Question

Something strange is happen. I tried all the best way I can but not able to get the correct solution for it. Rectenly I am working on one project in which dlib and open cv lib is used for face detection. The thing is I am able to achieved that but after window update I am not able to use Open Cv any function. Meanwhile dlib is working fine for me. I am getting now compile time error as well. But when ever I try to use even single line "cv::Mat image;"I am getting error "dll not found". I tried to rebuild it (64 bit). I tried to install Window Media Features also. I don't know whats gone wrong here. If anyone is aware of such issue please suggest.

Answer 2

Can you check path environments for opencv? Did you add OpenCVx.x\bin ? Maybe after update, binary and library paths are changed.
