[vlc] using v4l (WinTV) as input for vlc

[Spiceland, Michael D. Mr. RTTC]

We are trying to use a v4l device, namely a WinTV card, as input to stream
on the network.  I was trying this with the CVS of VLS, but for now I'm
giving up and going to try to get it to work with vlc.

I am able to stream the sample .vob file just fine.

I am able to use xawtv and others to use the v4l card just fine.

I am interested in streaming the composite video (channel 1) from the WinTV
card.  I am using the command line below:
vlc -vvv
v4l:/dev/video0:norm=ntsc:frequency=0:channel=0:size=640x480:adev=/dev/dsp:a
uido=0 --sout
'#transcode{vcodec=mp4v,acodec=mpga,vb=3000,ab=256,vt=8000000,keyint=80,dein
terlace}:std{access=udp,mux=ts,url=136.205.46.113}' --ttl 12

I have pasted the output at the bottom of this email.  Is there a way to
figure out where it is messing up?  Since it has to transcode the video to
mpg4, shouldn't there be allot of CPU usage?  I'm not getting much at all.

Thanks,
Michael
