FLEX 2.0 and Flash Media Server 2.0 Unable to stream from client to server

Question

Hi All,
I have been trying to put together a quick demo to stream
and record audio from Client to Server. I get this error when
trying to connect to FMS.
ArgumentError: Error #2126: NetConnection object must be
connected.
at flash.net::NetStream/flash.net:NetStream::construct()
at flash.net::NetStream$iinit()
at Audio/toggle()
at Audio/__submit_click()
my Program fails at this line - ns = new NetStream(nc);
Your help is greatly appreciated. Here is the MXML file
Audio.mxml
This file contains a simple start and stop button start and
stop audio processing.
This page is served from Apache Tomcat on host : demoserver1
and port 8080
Flash media server is also installed on the same host
demoserver1.
I did not do any additional config at FMS except creating an
application called "DemoApp". All other settings are defaults.

Hi,
Are you trying to make an air app or a web application (flash) for streaming? You may want to check out the osmf framework to help you write a player for mobile platform. Check out http://www.opensourcemediaframework.com/ for more info on how you can write streaming video players using this framework. There are some good tutorials there and also you may post on the forum to get your specific queries solved.
Thanks,
