Icecast dev - Dec 2006 - Icecast vs Internet Explorer 7 patch

Hi,

I have patched last night our icecast cluster to be compatible with IE7.

To be able to play icecast streaming inside a flash on IE7 you need :

1. Patch icecast2 to have content-length equal 319324133 (one more will 
failed)

2. Use javascript to display emb/object of the flash because Microsoft
    will not autorun flash anymore (due to legal issue ?)
    read http://www.adobe.com/devnet/activecontent/articles/devletter.html

3. flash .swf need to be stored on icecast web directory. Security 
restriction
    like in the java to only open socket on the same host where applet 
is located.

This is a sample code to play icecast stream in a flash code

stream = new Sound();
domain = new String();
mount = new String();
port = new String();

domain = 'icecast.youdomain';
mount = 'myradio.mp3';
port = '80';

System.security.allowDomain('http://'+ domain);

stream.loadSound('http://'+ domain +':'+ port +'/'+
mount, true);
function callback() {
    stream.start();
}
stream.onSoundComplete = callback;
stream.start();


Happy Christmas.
