[Icecast] live video windows

[Balint Jacint]

Hi,

Does Icecast2.3 handle wmv (windows media video) format streams?
I need to set up a live streaming service. It is important that no 
additional software should be installed on client side, so either need a 
flash player (or java based player if we have nothing else) or a format 
that can be played with the default Windows Media Player.
If it supports such things what software can I use to create the stream 
and send it to the Icecast server?
Has anyone ever made such thing?

Yours,
Jacint
