root window
SYNOPSISxscreensaver-getimage-video [-display host:display.screen]
[--verbose] [--stdout]
DESCRIPTION
The xscreensaver-getimage-video program is a helper pro
gram 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 sys
tem'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.
OPTIONSxscreensaver-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.
