使用FMS和Flex 4.7实现HLS (http实况流)的问题

Question

我在FMS 4.5 (也尝试使用FMS 5)实现HLS时遇到了一个问题。我正在关注这篇文章http://help.adobe.com/en_US/flashmediaserver/devguide/WSd391de4d9c7bd6 09-52e437a812a3725dfa0-8000.html。

当我使用FMLE (Flash媒体实时编码器)将直播流发布到livepkgr应用程序时。它在我的ios设备上运行得很好。但是当我使用Flex4.7代码发布时，声音没有发出，甚至视频在ios设备上过了一段时间后也停止播放。

任何人都知道为什么会发生这种情况。任何帮助都将不胜感激。

我正在添加要审查的代码。(您可以创建一个flex项目，并在creation_complete事件上调用"windowedapplication1_creationCompleteHandler".并将FMS_serverIp更改为reall fms服务器ip。

您的NetStream对象很可能被垃圾收集器吃掉了。尝试将其声明为字段。相机也是如此。
