CAMV(1)CAMV(1)

NAME

camv – USB camera display

SYNOPSIS

camv cam-device

DESCRIPTION

Camv uses the cam-device file tree provided by nusb(4) to use and control a USB camera. It opens the tree’s video file to play the video stream directly in the window.

The middle mouse button menu shows and allows editing the current picture settings. While it lists resolution, format and framerate per second, those must be set manually before starting camv(1). One can quit the program from the right mouse button menu.

EXAMPLES

Initialize and configure a camera before starting camv in its own window.

	cat <<EOF >/dev/cam5.1/ctl
