		<description><![CDATA[前两天我在折腾Flex的VideoDisplay控件并且好奇为什么我的简单测试代码无法通过。原因是我的服务器无法连接以至无法读取Flash媒体文件（FLV）。于是我很快的敲下了下面的代码利用stateChange事件来监听，来看VideoDisplay控件所得到的connectionError的状态（返回值是否为VideoDisplay.CONNECTION_ERROR常量）。
接下来的例子演示了如何监听stateChange事件来判断VideoDisplay控件是否返回了VideoEvent.CONNECTION_ERROR。
下面是完整代码：
