can't make my acquis card work... help please

[iboadi]

Hy,
I want to stream from my acqusition card. I use a BW camera on the composite entry. I have a Brooketree bt848, which is apparently recognized by mandrake 10 as a v4l device. I asked the person who is in charge of vlc for mandrake, he wrote to me, saying that for vlc 0.8.0 v4l for mandrake is in fact enabled, contrary to what is written in the HOW TO.
I have followed the instructions in ch.8 of HOW TO, but as do not intend to stream sound, I arrived at this command
vlc -vvv v4l:/dev/video:norm=pal:frequency=15625:size=640x480:channel=1--sout '#transcode{vcodec=mpgv,vb=500,vt=400000,keyint=80,deinterlace}:std{udp,mux=ts,url=172.16.23.83} --ttl 12

What is wrong with it, cause I do this in the command line and it does nothing. Or close to nothing.
It put to the next line a
>
sign and that is alll.
thanks,
adi
