Java:捕获屏幕上显示的视频 [英] Java: Capture video of what's on the screen

问题描述

我们正在考虑用Java编写一个软件，该软件可以在运行期间记录监视器.您对如何有效捕获监视器输出有任何建议吗?

We are considering writing a software in Java that records whats monitor for certain durations of time while it is running. Do you have any suggestions on how to efficiently capture the monitor output?

占用的CPU越少，我们捕获屏幕的频率就越高，并且在不干扰正在运行的其他应用程序的情况下生成的视频越平滑.

The less CPU it takes the more often we can capture the screen and the smoother a video we can generate without interfering with the other apps that are running.

如果复制屏幕捕获部分不太困难，则Java中的现有开放源代码程序将起作用.我希望它不需要调用另一种编程语言.我们将会看到.

An existing Open Source program in Java would work if it is not too difficult to copy out the screen capture section. I hope it won't require a call to another programming language. We will see.

推荐答案

我不确定您是否需要框架.

I'm not sure if you'll need a framework.

查看 java.awt.Robot 类的文档，特别是 createScreenCapture 方法的文档.

Check out the documentation for the java.awt.Robot class, specifically the createScreenCapture method.
