Question

我在Windows 7 32位操作系统中将opencv 2.4.10与Visual Studio 2010一起使用...

由于我是该 Realm 的新手，所以我首先尝试显示图像...效果很好...但是当我显示视频时，出现了此异常...并且下面提供了代码...谢谢...

  #include <opencv2/core/core.hpp>
  #include <opencv2/highgui/highgui.hpp>
  #include <iostream>
  using namespace cv;
  int main(int argc, char** argv)
{
string filename = "C:/Users/Public/Videos/Sample Videos/Wildlife.wmv";
VideoCapture capture(filename);
Mat frame;
if( !capture.isOpened() )
    throw "Error when reading steam_avi";
namedWindow( "w", 1);
for( ; ; )
{
    capture >> frame;
    imshow("w", frame);
    waitKey(20); 
}
waitKey(0);
}

尝试添加try { ... } catch(cv:Exception const& e){}子句，以查看问题的e.what()。
