Hi,
Reading a previous mail about capturing images with a webcam, I wonder if
I could do the same thing with mine. After looking up to by-pass the
default web interface, I've tryed with avec vlc
http://192.168.29.113:80/mpeg4 and I got the following error trace (sorry
for the length but I don't know what info is relevant for you) :

Do you think the stream could be play in videolan ? Otherwise can I do
something to make vlc work, I'm looking at sources for another thing, so I
could look at that too but if you could help me a little bit I would
appreciate :-)
Thanks in advance
Steve
