NAME
xscreensaver-getimage-video - put a video frame on the
root window
SYNOPSIS
xscreensaver-getimage-video [-display
host:display.screen] [--verbose] [--stdout]
DESCRIPTION
The xscreensaver-getimage-video program
is a helper program for the xscreensaver hacks that manipulate
images. Specifically, it is invoked by xscreensaver-getimage(1)
as needed. This is not a user-level command.
This program grabs a random frame of video from the system's
video input, and then loads it on the root window. It does this by
figuring out which frame-grabbing programs are installed on the
system, and invoking the first one it finds. Then it runs
xscreensaver-getimage-file(1) to load that image onto the
root window.
OPTIONS
xscreensaver-getimage-video accepts the
following options:
- --verbose
- Print diagnostics.
- --stdout
- Instead of loading the image onto the root window, write it to
stdout as a PBM file.
