好的。。我已经试了三个星期了。看起来很简单。。我看过的大约200页都是这么说的。把一个icecast音频流读成javascript。无论我做什么…读什么,我都会得到同样的错误。。。。
由于的CORS访问限制,MediaElementAudioSource输出零http://192.168.0.27:8010/stream.mp3
包括我使用的2个文件。。
Icecast xml文件。。。

<!-- Global header settings
Headers defined here will be returned for every HTTP request to Icecast.
The ACAO header makes Icecast public content/API by default
This will make streams easier embeddable (some HTML5 functionality needs it).
Also it allows direct access to e.g. /status-json.xsl from other sites.
If you don't want this, comment out the following line or read up on CORS.
-->
<http-headers>
<header name="Access-Control-Allow-Origin" value="*" />

我尝试了很多不同的方式。。或者无论我读到什么文件,似乎都不起作用。不想使用任何花哨的库。试着自学代码。
将'crossorgin="anonymous"'添加到html标记中。
<audio controls crossorigin="anonymous">
<source src="http://myicecastserver.dns/mount" type="audio/mpeg" />
</audio>
我也遇到了同样的问题,在玩这个游戏时,通过在音频标签中添加交叉原点元素来解决这个问题:https://www.bignerdranch.com/blog/music-visualization-with-d3-js/
