help,vlc streaming command

[microgiant]

hi all
i use the command:
vlc -I dummy -vvv F:\1.mov --sout '#duplicate{dst=rtp{mux=mp4v,dst=192.168.1.3,sdp=file://d:\1.sdp,name="TestStream"}}'

but the vlc says:"no mux specified or found by extension"

the command is not correct?

Any help would be greatly appreciated..

Did you mean mux=mp4?
