from vlc encoder to vlc server multicast streming

[fgenc]

my destination is to encode a device at a winxp client
and to send it to linux server which will work as a multicasting server

my problem is to stop trancoding at linuxserver

i send the encoding from encoder client to server with this parameter

:sout=#transcode{vcodec=WMV2,vb=1024,scale=1,acodec=mp3,ab=192,channels=2}:duplicate{dst=std{access=mmsh,mux=ts,dst=:1234},dst=std{access=rtp,mux=ts,dst=myserver.com:1234}}



this code run at linux server

vlc -vvv udp://@:1234 --sout '#transcode{vcodec=WMV2,vb=64,scale=1,acodec=mp3,ab=64,channels=2}:duplicate{dst=std{access=mmsh,mux=asfh,url=:1235}}'


lik you see i use transcoder if i user standart the stremming would bigger as encoder client send it

how can i send it at multicast without comming stremming will bigger

why !!!
