[Icecast] ICECast in Flash / IEWin

I'd like to resurrect this orphaned thread:


We're using the embedded flash player for listeners of pulverradio.com 
and can't use 2.2 for relaying from our encoders.  Apparently we can 
use Icecast v1.3

Although this is clearly a problem caused by ActiveX and Microsoft 
boneheads that is a mountain that may prove difficult to heave in a 
timely manner.

The fact that it can work with 1.3 indicates that there may have been 
some behaviour in the old version that was improved upon for 2.x ... 
perhaps future versions of Icecast could have a configuration flag to 
deprecate 2.x behaviour to 1.3's styling for headers (which in my 
limited understanding is where the problem lies), simply as a work 
around for the problem that would still allow us to use the cool new 
relaying features of 2.0 in our implementation.



A message from my developer on the issue follows:

Another long night.
I've been trying to find a way to make the streams work perfectly with 
Icecast.  There is a forum-documented problem with Icecast 2.0.
Streams play fine in Flash under the following circumstances:
- PC Mozilla / Opera
- All other flash supported platforms.
- Standalone

But not in IE on the PC.  This is because MS implements the Flash 
plugin as an ActiveX control, and not as a third party plug-in.
The difference in that regard between 1.3 and 2.0 is a mystery and 
neither Macromedia nor Icecast has an explanation.
I've tried several suggested solutions, including faking the headers 
via a PHP passthru, faking the incoming filename, connecting to either 
the m3u or direct to mp3, but no success.  The data is being 
transferred to the client, but the Flash never plays the stream when 
embedded in PC IE.
Did you use Icecast v1.3 for the original stream I tested with in 
June?  If so, my question: What's the advantage in using 2.0?
It's documented that the problem doesn't exist in 1.3.  And I had no 
problems embedding the original stream back then.
