如何在Linux帧缓冲区上截屏截图或电影 [英] How to screen capture screenshots or movies on the Linux framebuffer

问题描述

如何在Cell Linux上捕获Linux帧缓冲区以获取屏幕快照或电影？

How can the linux frame buffer, on Cell Linux, be captured to obtain either screen shots or movies?

是否有工具针对正在运行的程序执行此操作，还是写入并可能控制帧缓冲区的程序还可以处理捕获和记录？如果是这样，程序将如何执行呢？

Is there a tool to do this for a running program, or must the program writing to, and presumably controlling, the frame buffer also handle capture and recording? If so, how would the program do so?

推荐答案

许多这样做的工具，例如 FBGrab 和 fbdump ;查看这两个源，很容易扩展其中一个或编写自己的视频而不是快照。

Many tools for doing so, for example FBGrab and fbdump; look at the sources for those two, it would be pretty easy to extend either one or write your own which captures video instead of just snapshots.

但是，我建议将写入帧缓冲区的程序也记录为一个记录，以便使捕获帧在写入帧之间同步（而不是部分地通过写，跳过或...）

However, I would recommend that the program writing to the framebuffer be the one recording as well, in order to synchronize capturing frames between writing them (and not partially through a write, or skipping, or ...)
