<B>© <A href="/~rasca/">Rasca</A>,
Berlin 1998-2001, published under the <A href=COPYING>GNU GPL</A></B>
<BR>
<B>Note: This <A href="http://hoohoo.ncsa.uiuc.edu/cgi/">CGI</A> is for
<A href="http://www.linux.org/">Linux</A> running a kernel of the
<A href="ftp://ftp.kernel.org/pub/linux/kernel/v2.2/">2.2.X</A>
series or newer!</B>
<P>
<EM>w3cam</EM> is a simple CGI to retrieve images from a so
called <EM>video4linux</EM> device. In other words this program
will only run on Linux machines which support a <eM>video4linux</EM>-device.
<P>
<EM>w3cam</EM> supports a plain mode and a gui mode. In the gui mode
a html with a form is supplied to change some parameters with the mouse ..
<P>
<UL>
<LI>Supported output formats: <A href="http://www.libpng.org/pub/png/">PNG</A>,
<a href=http://www.jpeg.org/>JPEG</a> and PPM
<LI>Screen dumps in GUI mode <A href=double.jpg>double.jpg</A>
<LI>Installation: run '<CODE>configure & make install</CODE>' and edit the
installed <EM>w3cam.cgi.scf</EM> file
for the runtime configuration.
<LI>Usage:
Install the CGI and then call <code>{url}/w3cam.cgi?help</code>
<LI>Download source code: <A href=/~rasca/w3cam-0.7.2.tar.gz>
w3cam-0.7.2.tar.gz</A>
<LI>Needed Libraries: <a href=http://www.zlib.org/>libz</a>, libpng, libjpeg
<LI>Checkout <A href=ChangeLog.txt>ChangeLog</A> for changes since the last release.
<LI>Tips:
<UL>
<LI>Don't use <code>refresh=0</code> if you are not the only one, who
want to access the video, cause this will lock the v4l device.
<LI>Set <code>refresh=-1</code> if the image is NOT embedded in a
<a href=http://www.w3.org/MarkUp/>HTML</a>-page
(or set it at compile time as the default or at runtime
in the configuration file).
<LI>Use w3cam.css to change the layout (don't forget to install and
define the URL in the config file..)
</UL>
