尝试播放视频时断言失败 (ssize.area() > 0) 错误

Question

这是我的代码：

loadButton = new JButton("Open a video", createImageIcon("resources/Open16.gif"));

JFileChooser fc = new JFileChooser();
FileNameExtensionFilter filter = new FileNameExtensionFilter("Video Files", "avi", "mp4", "mpg", "mov");
fc.setFileFilter(filter);
fc.setCurrentDirectory(new File(System.getProperty("user.home"), "Desktop"));
fc.setAcceptAllFileFilterUsed(false);

loadButton.addActionListener(event -> {
    int returnVal = fc.showOpenDialog(null);

    if (returnVal == JFileChooser.APPROVE_OPTION) {
        File file = fc.getSelectedFile();

        videoPath = file.getPath();
        field.setText(videoPath);
        capture = new VideoCapture(videoPath);
        capture.read(currentImage);
        videoFPS = capture.get(Videoio.CAP_PROP_FPS);
        resize(currentImage, currentImage, new Size(640, 360));
        updateView(currentImage);

    }
});

这会导致这个错误：

OpenCV 错误：在 cv::resize、文件中断言失败 (ssize.area() > 0) C:\builds\master_PackSlaveAddon-win32-vc12-static\opencv\modules\imgproc\src\imgwarp.cpp, 线程“AWT-EventQueue-0”CvException 中的第 3229 行异常 [org.opencv.core.CvException: cv::Exception: C:\builds\master_PackSlaveAddon-win32-vc12-static\opencv\modules\imgproc\src\imgwarp.cpp:3229： 错误：(-215) ssize.area() > 0 in function cv::resize]

我认为您使用了错误的调整大小方法（有不同的方法具有相同的名称）。请改用Imgproc.resize(...)。还请出示您的进口商品。
