As of today there is a new version of Dreambox ReStream. It is version 1.4. Version 1.3 has never been released if you wonder....
This version supports now Flash streaming in H.264 video and MP4A audio. All you need a working Wowza Media Server. And the great thing is that it is FREE! For 10 concurrent users. So that should do. It can be installed on Windows and Linux.
For now it is not possible to have the Wowza server on a different server than VLC and the webserver.
For downloading Wowza Media Server click here. You can also order a free trail license for 10 concurrend users.
The setup you have to install the example application RTPNativeStreaming. And you have to name it 'rtplive'. You don't need to install the HTML and flash files. So you can stop at step 4. For more information check this forum thread.
This release also contains the XAJAX software. So there is no need to install that part separated.
Download and changelog is here.
