c++ - 模拟一个显示器，在windows上获取视频流

Question

有没有办法让我以编程方式在 Windows 中设置假监视器并从中获取视频流？ win32 api 中是否有允许我执行此操作的内容？

谢谢

我认为 Windows 桌面对象就是您的答案。下面是一个使用它们的应用程序示例:

Unlike other virtual desktop utilities that implement their desktops by showing the windows that are active on a desktop and hiding the rest, Sysinternals Desktops uses a Windows desktop object for each desktop. Application windows are bound to a desktop object when they are created, so Windows maintains the connection between windows and desktops and knows which ones to show when you switch a desktop. [...]

Desktops reliance on Windows desktop objects means that it cannot provide some of the functionality of other virtual desktop utilities, however. For example, Windows doesn't provide a way to move a window from one desktop object to another, and because a separate Explorer process must run on each desktop to provide a taskbar and start menu, most tray applications are only visible on the first desktop. Further, there is no way to delete a desktop object, so Desktops does not provide a way to close a desktop, because that would result in orphaned windows and processes. The recommended way to exit Desktops is therefore to logoff.
