Beginner's guide to streaming video with Flash Media Server 3.5
Flash Media Server (FMS) is a proprietary data and media server from Adobe Systems (originally a Macromedia product). This server works with the Flash Player runtime to create media driven, multiuser RIAs (Rich Internet Applications). The server uses ActionScript 1, an ECMAScript based scripting language, for server-side logic. Prior to version 2, it was known as Flash Communication Server.
