MPD 挂载点未显示在 icecast 上

【中文标题】MPD 挂载点未显示在 icecast 上

【英文标题】：MPD mountpoint not showing up on icecast

【发布时间】：2016-01-06 08:31:52

【问题描述】：

我正在尝试设置 MPD 以与 Icecast 一起设置互联网广播流媒体服务。 MPD 和 Icecast 似乎工作正常。但是，我在 icecast 的仪表板上没有看到 Mountpoints 下列出的任何内容。需要做些什么来启用相同的功能

这是我的配置文件。你能帮我解决我可能遗漏的问题吗？

【问题讨论】：

MPD 日志与配置不匹配。它试图连接到 ::1 而配置状态为 127.0.0.1。重启MPD，试试看。您也可以尝试添加<listen-socket><port>8000</port><bind-address>::</bind-address></listen-socket> 部分。

【参考方案1】：

这看起来应该工作。确保密码与 source-password 匹配。

看看/var/log/icecast/error.log 和/home/username/.mpd/mpd.log。如果您需要 Icecast 更详细，请将 loglevel 设置为 4 并重新启动。

这是哪个版本的 MPD？他们的一些版本在 Icecast 中表现出相当奇怪/不正常的行为。

【讨论】：

MPD : Music Player Daemon 0.19.12 编辑问题以包含错误日志

【参考方案2】：

在您的 MPD.Conf 文件中有两个 audio_output 部分。 第二个可以覆盖第一个。 所以删除/禁用配置结束时的部分

> #audio_output 
> #    type "alsa"
> #    name "username"
> #    driver "null"
