Software to stream Video from Server

Are there any out of the 开发者_C百科box programs / server software that I can install on my server to stream videos? I found XMoov while searching, are there any others? Which one is best?

After waiting and did not get any good answer, i will give a try to : http://stream.xmoov.com/ and let you know if i go the manual way, thanks anyway !

u Can youse javascript to ajax fetch the video, display in browser. But i don'\t know if that will scale to millions of use.rs
