man gqcam (Commandes) - GTK Webcam Control

NAME

gqcam - GTK Webcam Control

SYNOPSIS

gqcam [options]

DESCRIPTION

This manual page documents briefly the gqcam aplication.

Gqcam is a program originally created to pull frames from a greyscale Connectix QuickCam, but that has grown into a frame grabber for most any Video4Linux compatible webcam-like camera. It should work with any camera that supports the read() method of grabbing frames.

Make sure your kernel has Video4Linux support for your camera either compiled in or built as a module (for more information on recompiling kernels, take a look at http://www.linuxdoc.org/). Insert the Video4Linux modules if you need to ("modprobe c-qcam" for a Color QuickCam, "modprobe cpia" or something similar for a CPiA based camera, etc), and run gqcam to get things going.
