我已经在我的 Windows 8 系统上设置了 RED5 1.0 Final，我正在尝试让录制正常工作。我读过的一个教程说要在客户端（在 Flash 中）缓冲数据，然后一旦缓冲区为空，就关闭连接。
我遇到的问题是，当我开始记录缓冲区时，立即报告它是空的（NetStream.Buffer.Empty）。我已经让它在缓冲区实际填满的地方工作了一两次，但由于某种原因它停止了这种工作。
我可以看到即使在我将相机从网络流中分离后，客户端仍在向服务器发送数据，因为服务器端的文件继续增长。我目前的解决方案是在录制停止后等待 60 秒，然后再关闭连接。
有趣的一件事是，当没有更多数据包要发送时，我在服务器端看到文件从 mystream.ser 切换到 mystream.flv 并且大小停止增长。我正在考虑在服务器端编写一些代码来等待这个事件发生，然后让客户端知道它可以关闭流。
这是我第一次涉足动作脚本，所以我可能在这里做了一些完全错误的事情。请告诉我。
编辑这是客户端代码
