如何在Qt中显示其他应用程序的输出视频? [英] How to show output video of other application in Qt?

问题描述

我正在 Qt 中创建一个 GUI 应用程序.此应用程序将显示与 Qt 无关的应用程序 X 的输出，因此我无法集成它.X 将输出视频.这个视频没有路径，因为它是X输出的实时显示.

I am creating a GUI application in Qt. This application is to display output of a application X which is not related to Qt hence i cant integrate it. X will output a video . This video do not have a path since it is a real-time display of X output.

我想在 Qt 中显示此输出(以及一些后台 GUI 支持).

I want to show this output in Qt (along with some background GUI support).

据我所知，一种方法是获取视频的窗口 ID 并在 QWidget 中显示相同的窗口.如何做到这一点?
