Linux 录制桌面的简单工具
It's actually an application named <em><strong>recordmydesktop</strong></em>, which can be installed by <strong>sudo apt-get install recordmydesktop</strong>.
There are various kinds of purpose to use, but for me, I would like to present or show some mock-up to other people. I made a simple file
<strong>#!/bin/bash
recordmydesktop -windowid $( xwininfo -frame | awk '/Window id:/ {print $4}' )</strong>
After running this script, there is a cross cursor which allows you to select a window. As soon as the window is selected, the recording start. To end the recording, simply type Ctrl+C. After several lines of screen output, there is a .ogv file generated.
You can use Movie Player to view the file if you are using Linux. However, you can still view this file by using VLC, which can be installed to both Mac and Windows.
