you can setup crtpm server, its a great working streaming server and easy to setup
able to stream flash, mp4 everything
http://www.rtmpd.com/
you encode via adobe flash encoder
and put the adress of your streaming server into a flash, html5,jw whatever player and here it goes
needs some knowledge of handling a shell to install it
works great on centos
you can do relay, playlist or feed live with a flashliveencoder (plug in camera into videocard of your computer)
no fucking ads from a third party and no subscription fees
you only pay for your own traffic, but good if you want to sell an adult related service to a limited user group
also its more performant then wowza because its coded in c++ and not in javascript and free of any license charges
