Linking to a webcam using Flash Pro

Linking to a webcam using Flash Pro

I was experimenting in my fla file today trying to capture a live webcam
and audio using Flash Professional with ActionScript 3 code. When I hit
CTRL+enter I get this error in my output.
ArgumentError: Error #2126: NetConnection object must be connected at
flash.net::NetStream/ctor
Any ideas as to why this isn't working? Here is the (I think relevant)
code: What ami doing wrong what i am i missing? Interested to hear your
thoughts thanks.
