streaming with a CSA key in command line

[church]

How do you specify to use a CSA key while using command line? Im trying to stream video over rtp multicast using a batch file and i dont know how to specify in the command how to utilize a CSA key. I have looked through the command list and its not that clear as to where to place and what to place in the command. This is what I have right now. Any ideas?

:sout=#transcode{vcodec=mp1v,vb=1024,scale=1} :duplicate{dst=display,dst=std{access=rtp,mux=ts, dst=224.1.1.1:1234}}

Hi, put after of all these --sout-ts-csa-ck="123456789ABC...". Some 16 hex code
