This gist shows how to create a GIF screencast using only free OS X tools: QuickTime, ffmpeg, and gifsicle.
To capture the video (filesize: 19MB), using the free "QuickTime Player" application:

Adobe Scout 是优化Flash内容异常强大的工具,因为他可以让你看到在Flash播放器里场景背后真正发生了什么.但只有当你理解了Flash播放器为什么那么做的时候那些信息才是最有用的.也只有那时候你才能有效地解决Scout告诉你的问题. | |
这篇文章的目的是让你对Flash播放器如何工作有一个基础的理解,并且理解与此相关的在Scout里看到的信息.这也是Scout中用到的terminology的一个指南,因此你可以找到Flash播放器执行的不同的活动的意义.如果你用过Scout并且有"我发现我的程序花了很多时间在做X上,但我不知道X是什么意思"的疑问的话,这篇文章正适合你! | |
注意这不是一个使用Scout界面的指南.如果你不知道如何使用Scout,或者不同的面板干什么,那么你需要读一下[开始指南|http://www.adobe.com/devnet/scout/articles/adobe-scout-getting-started.html]. |
