Steamcast
Steamcast is a freeware streaming media server that extends the capabilities of the Icecast2/ SHOUTcast framework. The creators of Steamcast intend for the project to be format/ codec agnostic and want to support as many encoding, listing ( YP) and client systems as possible. Steamcast can function as an on-demand multimedia server as well as a web radio or internet radio broadcast server. With the use of NSV Steamcast can also be utilized as a live video streaming server. Steamcast is currently available for Microsoft Windows, FreeBSD, and Linux.
