使用 Icecast 自定义元数据
我需要向 Icecast 流添加额外的元数据（除了艺术家和歌曲标题之外）。我尝试了很多想法，但似乎都没有产生任何效果。情况变得更加复杂，因为元数据也通过 Wowza，它正在重新传输 Icecast 流。是否有 Icecast 支持的元数据字段的规范列表，是否有人有将自定义元数据作为 Icecast 流的一部分传递到 Wowza 的经验？
I need to add additional metadata to an Icecast stream (beyond Artist and Song Title). I've tried a number of ideas but none seems to yield anything. The situation is made more complicated in that the metadata also passes through Wowza, which is re-streaming the Icecast stream. Is there a canonical list of metadata fields supported by Icecast, and does anyone have experience passing custom metadata as part of an Icecast stream and on to Wowza?

我的
node-icy模块能够读取任意 Icecast 流拦截“元数据”事件和/或将“元数据”事件添加到输出流。您本质上是在“代理”流。一个很好的（虽然有点复杂）示例可能在这里：proxy.js请注意，虽然“元数据”格式是分号分隔的键值对字符串，但 Icecast 客户端仅对
StreamTitle值，因此只需将您想要的所有信息填充到其中即可：我已经做了一些事情，例如每秒发送一个元数据事件来保留轨道位置计数器（尽管这可能有点网络繁重） ）：
祝你好运！

node-icymodule is capable in reading in an arbitrary Icecast stream and intercepting and/or adding "metadata" events to an output stream. You are essentially "proxying" the stream. A good (though slightly complicated) example might be here:proxy.jsDo note though that the "metadata" format is a semicolon-delimited String of key-value pairs, but Icecast clients only react to the
StreamTitlevalue, so just stuff all the information you want into there:I've done things like send a metadata event every second to keep a track position counter (though that may have been a little network-heavy):
Good luck!
尽管有点复杂，但 Savonet/Liquidsoap 脚本语言具有修改/设置流元数据的功能。 Liquidsoap wiki 中有几个示例，网址为 https://wiki.sourcefabric.org/display/LS/用户脚本
Though it's a bit complicated, the Savonet/Liquidsoap scripting language has facilities to modify/set stream metadata. There's a couple examples in the Liquidsoap wiki at https://wiki.sourcefabric.org/display/LS/UserScripts
