Unreal Streaming Technologies have recently released version 7 of Unreal Media and Live servers, adding H.264 encoding and the ability to stream to Flash player through the support of the RTMP protocol.

Anyone can download these products from http://www.umediaserver.net/umediaserver/download.html

The Unreal Live Server which serves as a video encoder similar to Adobe FMLE, is completely free of charge, while Unreal Media Server has certain concurrent connections limitation in its free version, and requires licensing.

These streaming tools have a very small download size and small footprint on your system when installed. They have GUI front-end and easy to operate, although they have slightly different concept of operation comparing to other encoders such as Adobe FMLE or Telestream encoder.

The main feature that differentiates Unreal Live Encoder from Adobe FMLE and others is unmanned, automated operation. You configure the system and leave.
Adobe FMLE generally requires a presence of the operator who opens the encoder and presses 'Start Encoding' button. This is good for broadcasting events but may be unacceptable for a system that needs to start broadcasting anytime when somebody wants to watch/listen, such as IPTV, radio, video surveillance, digital signage apps, etc.
Unreal Live Server running as a Windows service will start encoding and streaming when a first viewer sends request for live video by opening a player. It will stop encoding and streaming when a last viewer disconnects.

The latest version of Unreal Media's software adds itself to a small family of free software tools for live Flash streaming.
