python - 使用 python-shout 创建 icecast2 服务器的多个音频流

Question

我正在尝试创建一个网络广播服务器来同时流式传输 3 个源。我正在使用 python 使用 python-shout 库为 icecast2 创建源客户端。我不太熟悉这种语言(python)。但是，我得到了一个示例程序，它可以完成我需要做的事情，而且我已经根据需要对其进行了调整。但是，我只能创建两个流，之后，我收到如下所示的错误消息。我不知道我做错了什么，所以我希望你们能帮我解决这个问题。

hostname ="localhost"
port= 8000
password = "password"

我收到的错误消息

如有任何帮助，我们将不胜感激。

所以，事实证明我的代码是正确的。问题出在 Icecast 的配置中。默认情况下，只能创建两个流。在 icecast 配置文件中编辑后，一切正常。谢谢。
