OpenCV C++ cannot open video unless program is run as root - c++

Question

I'm trying to open a video file in Opencv C++, but it doesn't work in a weird way.
I'm on Fedora, and opencv is installed through dnf's opencv-devel package.
Here is the test code I'm using :
#include <iostream>
#include <opencv2/core/core.hpp>
#include <opencv2/imgcodecs/imgcodecs.hpp>
#include <opencv2/imgproc/imgproc.hpp>
#include <opencv2/highgui/highgui.hpp>
#include <opencv2/videoio/videoio.hpp>
int main(int argc, char *argv[])
{
std::string imagePath = "/home/me/picture.png";
cv::Mat image = cv::imread(imagePath);
std::cout << image << std::endl;
std::string videoPath = "/home/me/video.mp4";
cv::VideoCapture cap{ videoPath };
if(!cap.isOpened())
{
std::cout << "Error while opening video" << std::endl;
return -1;
}
cv::Mat startFrame;
cap >> startFrame;
std::cout << startFrame;
cap.release();
return 0;
}
Then, I Compile it with the libraries:
g++ -c -Wall -Wno-unknown-pragmas -I/usr/include/opencv4/ -o dist/obj/main.o src/main.cpp
g++ -lopencv_core -lopencv_highgui -lopencv_imgcodecs -lopencv_imgproc -lopencv_videoio dist/obj/main.o -o dist/bin/main
And when I run it, the image is read fine, but the video shows an error.
However, when I run it as sudo, the video reads just fine. I searched around a lot and couldn't find someone with a similar problem, so I'm posting this here.
Also, the python version works fine, so it shouldn'ttm be a codec problem.
