Linux上的OpenCV - 损坏的JPEG数据：标记0xd3之前的1个无关字节

Question

我在我的linux薄膜机上运行openCV中的一些代码，以从我的网络摄像头获取图像并进行一些图像处理。但是，当我运行此代码时，图像似乎已损坏。我一直在我的终端收到此消息，而我的代码正在运行：

Corrupt JPEG data: 1 extraneous bytes before marker 0xd6
Corrupt JPEG data: 1 extraneous bytes before marker 0xd4
Corrupt JPEG data: 2 extraneous bytes before marker 0xd6
Corrupt JPEG data: 2 extraneous bytes before marker 0xd0
Corrupt JPEG data: 1 extraneous bytes before marker 0xd5
Corrupt JPEG data: 2 extraneous bytes before marker 0xd2
Corrupt JPEG data: 1 extraneous bytes before marker 0xd3

代码：

 int main()
{

    cv::Mat frame;

    VideoCapture webcam;


    if (!webcam.open(0))
    {
        cout << "file not opened"<<endl;
        waitKey(0);
        return EXIT_FAILURE;
    }

    for(;;)
    {
          Mat frame;
          webcam >> frame;
          if( frame.empty() ) break; // end of video stream
          imshow("this is you, smile! :)", frame);
          if( waitKey(10) == 27 ) break; // stop capturing by pressing ESC
    }
}
