推荐答案

流正常运行不需要元数据.如果您的数据已损坏，则说明您编码错误或发送了错误的Content-Type标头.

The metadata is not required for a stream to function. If your data is corrupt, you are either encoding it wrong or are sending the wrong Content-Type header.

话虽这么说，一旦您的流正常工作，如果您想发送元数据，则这是在实际音频流的带外完成的.通过向Icecast服务器的简单HTTP请求来更新元数据.

That being said, once you get your stream working, if you would like to send metadata, this is done out-of-band of the actual audio stream. Metadata is updated with a simple HTTP request to the Icecast server.
