Hello,m able to read images, but for some reason I'm unable to open any video. Thats what I get: cv::CvCapture_Images::open CAP_IMAGES: Stop scanning. Can’t read image file: c:/ttt.mp4
I
m pasting the code here, its basic, so I don
t think theres an issue with it.
#include <opencv2/imgcodecs.hpp>#include <opencv2/highgui.hpp>#include <opencv2/imgproc.hpp>#include #include <sys/stat.h>#include #include
using namespace cv;
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 dont 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 Im getting the same error…

Found the issue. Took me around 6h( Media Feature Pack for Windows 10 N (October 2020)
This is why the exact OS should be reported… Windows 10 N lacks those things by design.
) 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:
