Detailed description

If you try to create two cv::VideoCapture instance, camera indexes swap every run.

Steps to reproduce

Test Code

    cv::VideoCapture cap(0);
    cv::VideoCapture capSecond(1);
    
    if(!cap.isOpened() || !capSecond.isOpened()){ return -1; }
    
   

    cv::Mat frame, frameSecond;
    while( true ){
        cap.read(frame);
        capSecond.read(frameSecond);
        cv::resize(frame, frame, cv::Size(256,256), 0, 0, cv::INTER_LINEAR );
        cv::resize(frameSecond, frameSecond, cv::Size(256,256), 0, 0, cv::INTER_LINEAR );
        cv::imshow(std::string{"Cap 1"}, frame);
        cv::imshow(std::string{"Cap 2"}, frameSecond);
        cv::waitKey(100);
     }

First Run (for every number of odd try )

Second Run (for every number of even try )

Issue submission checklist

• I report the issue, it's not a question
• I checked the problem with documentation, FAQ, open issues, forum.opencv.org, Stack Overflow, etc and have not found any solution
• I updated to the latest OpenCV version and the issue is still there
• There is reproducer code and related data files (videos, images, onnx, etc)
