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.
