w3cam is a simple CGI to retrieve images from a so called video4linux device. In other words this program will only run on Linux machines which support a video4linux-device.

w3cam 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 ..

- Supported output formats: PNG, JPEG and PPM
- Screen dumps in GUI mode double.jpg
- Installation: run '`configure & make install`' and edit the installed w3cam.cgi.scf file for the runtime configuration.

- Download source code: w3cam-0.7.2.tar.gz

- Checkout ChangeLog for changes since the last release.
- Tips:
  - Don't use `refresh=0` if you are not the only one, who want to access the video, cause this will lock the v4l device.
  - Set `refresh=-1` if the image is NOT embedded in a HTML-page (or set it at compile time as the default or at runtime in the configuration file).
  - Use w3cam.css to change the layout (don't forget to install and define the URL in the config file..)
- Problems?: Mini FAQ, and also consult the included documentation and HTML samples.
