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.
