使用ffmpeg支持ICY元数据 [英] ICY metadata support with ffmpeg

问题描述

有没有办法使用FFMpeg从喊话流中获取ICY元数据？
一种方法是自己处理连接/流，并将自定义IOStream发送到ffmpeg。

还有其他简单的方法吗？或者分解者可用？

谢谢

但是，它看起来不像它那样。我建议你自己解析一下。请参阅我的答案：

或者，您只需访问 /7.html 在SHOUTcast服务器上，您将得到如下一行：

  1,1,15,625,1,128，呵呵 - 请留下
  

字段是：

1. 听众数量


2. 流状态（1表示你在空中，0表示来源不在）


3. 此服务器侦听器的峰值数量运行


4. 服务器配置允许的同时侦听器的最大数量


5. 侦听器的唯一数量，基于IP


6. 当前比特率（千比特）


7. 标题。 （请注意，即使您的标题中有逗号，也不会转义任何内容。）

请注意， /7.html 并不总是在非SHOUTcast服务器上可用，并且在新版本的测试版中可能不可用。虽然这是一种快捷方便的方法，但您最好分析发送给客户端的元数据。

Is there any way to get ICY metadata from shoutcast stream using FFMpeg ? One way would be to deal with the connection/stream by myself and send Custom IOStream to ffmpeg.

Is there any other simple way? or demuxer available ?

Thanks

There was discussion of a patch for supporting it here: http://web.archiveorange.com/archive/v/yR2T400567mWEyyZHg3k

But, it doesn't look like it made it in yet. I suggest you simply parse this out yourself. See my answer here for how to do this:

Alternatively, you can just access /7.html on SHOUTcast servers, and you will get a line like this:

1,1,15,625,1,128,Oh Mercy - Stay, Please Stay

The fields are:

1. Number of listeners
2. Stream status (1 means you're on the air, 0 means the source isn't there)
3. Peak number of listeners for this server run
4. Max number of simultaneous listeners the server is configured to allow
5. The unique number of listeners, based on IP
6. Current bitrate in kilobits
7. The title. (Note, even if you have a comma in your title, it isn't escaped or anything.)

Beware though that /7.html isn't always available on non-SHOUTcast servers, and may not be available in the beta of the new version. While this is a quick and easy method, you would be better off parsing the metadata sent to clients.
