xscreensaver-getimage-video: put a video frame on the root window

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.
