NAME
       zapping_setup_fb - prepares V4L/V4L2 driver for overlay

SYNOPSIS
       zapping_setup_fb [-?, -h, --help, --usage] [-b, --bpp NUMBER] [-c, --child] [-d, --device FILENAME] [-D, --display NAME] [-f, --fd]
			[-q, --quiet] [-S, --screen SCREEN NUMBER] [-v, --verbose] [-V, --version]

DESCRIPTION
       zapping_setup_fb is a small program to prepare Video For Linux (V4L) or Video For Linux Two (V4L2) video capture drivers for video overlay.
       It must be executed by pam(8) with root privileges, or owned by root with the set-user-ID bit set (see chmod(1)). This manual page refers
       to zapping_setup_fb version 0.13.

BACKGROUND
       To enable video overlay V4L and V4L2 drivers need to know the screen memory address. For security reasons only the system administrator can
       program this address.  zapping(1) delegates the task to this helper application.

OPTIONS
       -?, -h, --help, --usage
	   Prints usage information on stdout, then terminates the program.

       -b, --bpp NUMBER
	   Color depth hint, the number of bits per pixel on the display in question, either 24 or 32. Usually zapping_setup_fb can determine this
	   number automatically.

       -c, --child
	   Zapping sets this flag when executing zapping_setup_fb as child process to enable the output of localized error messages in UTF-8
	   encoding on stderr.

       -d, --device FILENAME
	   The video capture device to open, by default /dev/video0.

       -D, --display NAME
	   The X display to use. Defaults to the name defined by the DISPLAY environment variable.

       -f, --fd NUMBER
	   Zapping uses this option when executing zapping_setup_fb as child process to access the video capture driver by this shared file
	   descriptor instead of opening the device file by name.

       -q, --quiet
	   Decrements the verbosity level.

       -S, --screen NUMBER
	   The X screen to use (Xinerama), defaults to 0.

       -v, --verbose
	   Increments the verbosity level.

       -V, --version
	   Prints the version of zapping_setup_fb on stdout, then terminates the program.

BUGS
       None known.
