2016-04-04 23:36:53 -0600	commented question	OpenCV 3.1 x64 libs for visual studio 2015 I am having the same issue. How did you resolve it?
2016-04-04 23:35:00 -0600	asked a question	Cannot find additional libraries in openCV 3.1.0 I followed the instructions on installing openCV for Windows x64 (no I did not build it, I downloaded the precompiled binary). The instructions however were for v 2.4.2 All of it was relevant but I got stuck at this page http://docs.opencv.org/2.4/doc/tutori... where it talks about adding libraries to Linker ‣ General and under the “Additional Library Directories”. I cannot find any of these: opencv_calib3d249d.lib opencv_contrib249d.lib opencv_core249d.lib opencv_features2d249d.lib opencv_flann249d.lib opencv_gpu249d.lib opencv_highgui249d.lib opencv_imgproc249d.lib opencv_legacy249d.lib opencv_ml249d.lib opencv_nonfree249d.lib opencv_objdetect249d.lib opencv_ocl249d.lib opencv_photo249d.lib opencv_stitching249d.lib opencv_superres249d.lib opencv_ts249d.lib opencv_video249d.lib opencv_videostab249d.lib The only two I find are opencv_world310.lib and the debug version. And I end up with linking errors at run time.
2016-04-03 14:06:03 -0600	commented question	Sending rendered video stream to openCV thanks. now I have to figure out how to address a particular monitor since I have 2!
2016-04-03 00:44:59 -0600	asked a question	Sending rendered video stream to openCV Is there a way to use the output of a video game in real time as a stream to openCV? Although I can open saved .avi files in openCV, I would rather just pipe the video stream of the frame buffer directly to openCV. Right now I have a webcam pointed at the screen and am capturing the webcam with cap = cv2.VideoCapture(0)
