How to pragrammatically control Flash Encoder

Hello there,
I need to write a program which receives "START ENCODER", "STOP ENCODER", "START ARCHIVING", "STOP ARCHIVING" commands from a socket, here the "ENCODER" means the flash encoder, "ARCHIVING" means saving the encodings to a file.

I have surfed the web for a while but still the only link related is "http://flex.sys-con.com/node/388456". However the solution in this link is not enough for me. I also searched the command-line controls of the Flash Media Live Encoder, and seems it only has command -line controls to start and stop an encoder. Using these two command-line controls, I can write a C# program to fulfill "START ENCODER" and "STOP ENCODER" commands, but have no idea how to fulfill the other two commands "START ARCHIVING", "STOP ARCHIVING".

ActionScript came to my sight for many times, but seems I cannot use it to develop the program I want. Flash Media Live Encoder installs on Windows XP. I think I should use C# (or VB) on .NET to implement the program.

Any idea about my question? Thanks a lot for your reply in advance.
