FMS3系列(四)：在线视频录制、视频回放【转】

使用Flash/Flex+FMS实现在线视频录制、视频回放的很简单的。通过阅读API文档后基本都可以实现这个功能，本文也意在抛砖引玉，希望对刚入手这块的朋友有所帮助。

??????首先建立好Flash(ActionScript 3.0)文件，从组件（可使用Ctrl+F7打开）库中拖拽相应的组件到Flash舞台上，如下图：

????????????

??????界面布局好后我们通过程序设置组见的显示文本以及为按扭添加事件监听，新建一个ActionScript类文件，编写代码如下：

??????录制功能完成了，通过测试也可以成功的录制视频。最后我们通过程序来播放刚刚录制是视频。关于播放视频在上一篇文章《FMS3系列(三)：创建基于FMS的流媒体播放程序，看山寨帮的山寨传奇》中已介绍怎么实现，这里就直接帖出代码不做解释。
