Stream live video to AIR app - server requirements

Can anyone advise on the server set up/requirements to make an AIR for iOS app that displays live video from a (streaming?) server?

I have built AIR for iOS apps that display recorded video (.mp4) from a server using StageVideo but now I need to:

1. Record live video which could be a separate AIR for iOS app using the Camera Class or a video camera and upload to a server.

2. Stream the uploaded video to an AIR for iOS app in real-time.

The Adobe references I have found all seem outdated and refer to things like "Flash Media Server" which doesn't seem to exist or is no longer supported. Can anyone give me an idea on the setup that would be required for this?

Many thanks.
