This is a very simple, bare-bones live stream player page that you can use as a starting point. It contains the FlowPlayer flash player, configured to play the "Extremists" sample video which was deployed with your service.
The code of this page mirrors what is described in this knowledgebase article about using Flowplayer.
To test live streaming, use Adobe's Live Encoder, which can be downloaded from our downloads area, and set the FMS URL to rtmp://charlestoncrowd.com/live. Leave the stream name livestream, connect (you'll be prompted for your credentials from the instructions email) and start encoding, and you should see your live video on this page.
