Is it possible to get Icecast metadata from HTML5 audio element?

Question

I am using audio element to stream an ogg source from an icecast server. Does the audio element extract icy metadata and is there a way to access it through javascript?

Basically, I want to show "currently playing" information of a radio station I am streaming. What are my options?

Thanks!

No, your HTML5 elements are only aware of the stream data, and aren't even making the appropriate request to fetch the metadata.

See these posts:

• Developing the client for the icecast server

• Pulling Track Info From an Audio Stream Using PHP

• http://www.smackfu.com/stuff/programming/shoutcast.html

Now, this isn't impossible by any means. You just have to do it server-side. (See that second link in particular.)

I should also point out that on a full-blown SHOUTcast Server (haven't tested with Icecast, but its worth a try) generates "7.html" which contains data on the number of listeners, max listeners, peak listeners, stereo/mono, bitrate, and current track name as comma-separated values. Like this:

2,1,33,625,2,128,J Mascis - Not Enough

If you can fetch http://yourstreamingserver:port/7.html, then you can get this data very easily.
