gqcam - GTK Webcam Control


gqcam [options]


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 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.


Options for gqcam are:
-h, --help
display help screen and exit
-V, --version
display version and exit
-s, --swap
swap RGB into BGR (WARNING: this option will disappear in the future, turning into a filter instead)
-a, --autobright
perform autobrightness
-v, --video <video dev>
grab frames from <video dev>
-d, --dump <filename>
dump image to <filename> (or stdout if filename is "-")
-t, --type <type>
type of image to dump(default:PNG) (valid types: PPM PNG JPEG)
-b, --brightness <num>
set brightness to <num>
-w, --whiteness <num>
set white balance to <num>
-c, --contrast <num>
set contrast to <num>
-m, --maxfps <num>
set the maximum frames per second(default:10)
-F, --fullspeed <num>
display as many frames per second as you can
