I am using Flash Professional authoring tool with ActionScript 3 code. Basically, I’m trying to capture a live webcam feed using NetConnection, NetStream Camera and Video classes via Flash Media Development Server. When I run the code I receive this in my output:  
ArgumentError: Error #2126: NetConnection object must be connected. at [flash.net](http://flash.net)::NetStream/ctor() at [flash.net](http://flash.net)::NetStream()  
I don’t really understand what could be causing this error my code is perfectly fine…Its very frustrating. When I debug I get this:  
SecurityError: Error #2028: Local-with-filesystem SWF file file:///C|/Users/Name/AppData/Local/Temp/Untitled%2D1.swf cannot access Internet URL rtmfp://localhost/flashExam. [SWF] C:\Users\Name\AppData\Local\Temp\Untitled-1.swf - 3853 bytes after decompression  
It appears the swf file cannot gain access FMS. Why is this? And, does anyone know what I can do to resolve these issues? Thank You Very Much
