如何在此视频中解决此无限镜像效果 [英] How do I solve this infinite-mirror-effect in this video

问题描述

我有一个任务是使用OPENCV作为视频源捕获桌面或主动窗口，但结果在输出视频中提供无限镜像效果，有人说它与GetDesktopWindow有关，我也有一个功能从屏幕图像中创建一个名为hwnd2mat的位图

这是在main中：

Hi, i have a task to capture desktop or activewindow using OPENCV as video source, but the result gives infinite-mirror-efect in the output video, someone says it have something to do with the GetDesktopWindow , also i have a function that create a bitmap from the screen image called hwnd2mat
this is inside main :

HWND hwndDesktop = GetDesktopWindow();	
	int key = 0;
	while (key != 30 )
	{
		Mat src = hwnd2mat(hwndDesktop);		
		// you can do some image processing here
		imshow("output", src);
		key = waitKey(30); // you can change wait time
	}
	ReleaseCapture();
	destroyAllWindows();
	return 0;

我尝试过：



i使用FindWindow（）或FindWindowEx（）更改GetDesktopWindow（）并使用间谍++找到我不知道什么类，但我不知道如何做到这一点的例子，你能给我一个例子或解决方案吗？非常感激，我已经在这2天苦苦挣扎了。

What I have tried:

i change GetDesktopWindow() with FindWindow() or FindWindowEx() and using Spy++ to find the Class of i don't know what, but i don't know example how i do that, could you please give me an example or a solution for this? appreciate it very much, i've been struggling with this for 2 days.
