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. % nusb/cam 5 % window -dx 320 -dy 240 \ 'label cam cat <<EOF >/dev/cam5.1/ctl format 320x240 fps 30 backlight-compensation 1 brightness 20 contrast 95 saturation 40 sharpness 7 gamma 200 EOF camv /dev/cam5.1 ' SOURCE /sys/src/cmd/camv.c SEE ALSO nusb(4) HISTORY Camv first appeared in 9front (March, 2018).
