Icecast - Aug 2004 - Re: Viewing Broadcast using scope in a Webpage

Is there a method to code on XHTML webpage that will use a "scope" to 
display the music stream that is being played? (like something using 
JavaScript?)...

Just curious...

Hi Murray,

Depends on what data you want to use for that scope. ATM the only usefull data I
can see in the source file (/admin/stats.xml) would be number of listeners. If
you know about the bitrate of the stream you could translate this additionally
to bandwidth.

To realize this you have several choices:
- do something using the built in xslt possibilities.
- put out the raw listener numbers and process it with an external app
(php/gd/perl/python)

Depends on what you want to have as output...
I like my stats as a history graph:

This is accomplished using mrtg + some xlst + some wrapper so mrtg can read the
output.
I'll put up a webpage covering this topic, but am quite busy ATM. Don’t
expect this before middle/end of next week.
Oh, and - yeah uhh - nowadays I'd probably choose its successor RRDTool...
But should be fairly similar to set up.

Thomas

Hi Thomas,

So those possible solutions could allow for an audio spectrum analyzer 
to be on a webpage?
(i.e. like the ones you can see on XMMS or WinAmp?)
