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.
