vlc with (http) webinterface for capture card

[mrkptrs]

I run the following command to start a vlc stream server for my webcam with a http interface:
vlc C:\start.m3u --extraintf http --http-src c:\videolan\vlc\http\

the playlist start.m3u contains the following:
#EXTM3U
#EXTVLCOPT:dshow-vdev=Hauppauge WinTV Capture
#EXTVLCOPT:dshow-adev=
#EXTVLCOPT:dshow-size=320x240
#EXTVLCOPT:no-dshow-config
#EXTVLCOPT:no-dshow-tuner
#EXTVLCOPT:file-caching=300
#EXTVLCOPT:sout=#transcode{vcodec=mp4v,vb=1024,scale=1,acodec=mpga,ab=192,channels=2}:duplicate{dst=std{access=rtp,mux=ts,url=192.168.1.2:1234}}
dshow://

however, the server starts streaming immediately ('play' mode), although I would like to have it start in 'stop' mode.

does anyone know if this is possible and if so, what is the command to do this?

thanks in advance!
