Record stream from Flash Media Encoder

I am writing a flash program to record the stream (using ns.publish() function) that come from Flash Media Encoder. And it is not successful.

I check out the website, and most of the sample is capture the camera directly by using ns.AttachVideo(Camera.get()); function.

Could I attach the video that is come from Flash Media Encoder? coz I cannot use 2 programs (my programs and Media Encode Server) cameras at the same time. Thanks a lot!
