With an ICS account you have the ability to use 3 party application such as Comet Chat.
Simply Create you application through the ICS portal. For this example we will use avchat as the application name.
When you log into your comet chat administration portal select the audio video chat plugin and update the FMS path with the following.
Update the ICSACCOUNTINFO with the correct path. You have an additional bonus of using RTMFP to allow Comet Chat to connect saving you bandwidth on your account.
You can also use the rtmp path with encoder application to broadcast a live stream to a player.
You can use Flash Media Live encoder with the same path and simply create a stream name.
