Question

我正在尝试从网络摄像头获取提要，并使用VideoWriter将其存储在文件夹中，但是在可视化条件下运行代码后，它弹出此错误，提示新数组长度错误。执行未传递（isWriterOpened）语句。该程序在Visual Studio->调试模式->窗口控制台应用程序（x64）中完成。

 //create matrix to store image
Mat image;

//initialize the camera
VideoCapture cap;
cap.open(0);

if (!cap.isOpened()) {
    std::cout << "Cant get the feed from camera.";
    return -1;
}

//filename string
std::string filename = "C:/Users/Guru/Videos/OpenCV_Feed/myVideo.avi";

//fourcc integer
int fcc = VideoWriter::fourcc('M', 'J', 'P', 'G');

//frames size
cv::Size frameSize((int)cap.get(CAP_PROP_FRAME_WIDTH),(int)cap.get(CAP_PROP_FRAME_HEIGHT));

//frame per second
int fps = 20;


VideoWriter writer("outcpp.avi", VideoWriter::fourcc('M', 'J', 'P', 'G'), 10, frameSize);

if (!writer.isOpened()) {
    std::cout << "Writer is not opened";
    getchar();

    return -1;

}

错误我：错误：0] VIDEOIO（cvCreateVideoWriter_MSMF（文件名，FOURCC，帧，框架尺寸，isColor））：凸起C ++异常：坏阵列新长度
