Hello, I have a new installation installation of open cv 4.5.1 on windows, downloaded it built from sourceforge. I`m able to read images, but for some reason I'm unable to open any video. That`s what I get: cv::CvCapture\_Images::open CAP\_IMAGES: Stop scanning. Can’t read image file: c:/ttt.mp4 ![image](https://us1.discourse-cdn.com/flex020/uploads/opencv/original/2X/9/939e8946c28252003e8407e77de67aefeade3a95.png) I`m pasting the code here, it`s basic, so I don`t think there`s an issue with it. #include \ #include \ #include \ #include #include \ #include #include using namespace cv; using namespace std; void main() { ``` string path = "c:/ttt.mp4"; struct stat buffer; bool exist = stat(path.c_str(), &buffer) == 0; if (exist) { VideoCapture cap(path); Mat img; while (true) { cap.read(img); imshow("Image", img); waitKey(20); } } ``` } ---

What I find intersting is that I don`t have this file: opencv_videoio_ffmpeg451_64d.dll Took me a while to actually spot the D. I only have opencv_videoio_ffmpeg451_64, so I tried to rename it, but I`m getting the same error… ---

Found the issue. Took me around 6h( 🥺) to figure out that Windows 10 Pro N was missing some media functionalities. After installing the needed stuff, everything works like a charm. Check this link if you stumble upon the same issue: [Media Feature Pack for Windows 10 N (October 2020)](https://support.microsoft.com/en-us/topic/media-feature-pack-for-windows-10-n-october-2020-2f992f23-1fca-60a3-9907-fd4fe896a8a7) ---

This is why the exact OS should be reported… Windows 10 N lacks those things by design.
