Hello everyone, I am new here so forgive me if this is in the wrong place. I am new to shell script and am trying to write a script to use with a program called ffmpeg. Would this be something I could get help with here?
This allows you to paste the name of an mp4 file in the window and it will automatically make a folder and print out a frame by frame of the video in it. This was given to me and I added the little mp4 extension to it but that is as far as I can go. Would anyone here be able or willing to show me how to edit this further to do a few other things?
Thank you all for your time and help.

xscreensaver-getimage
xscreensaver-getimage(1) XScreenSaver manual xscreensaver-getimage(1)NAME
xscreensaver-getimage - put some randomly-selected image on the root window
SYNOPSIS
xscreensaver-getimage [-display host:display.screen] [--verbose] window-id [pixmap-id]
DESCRIPTION
The xscreensaver-getimage program is a helper program for the xscreensaver hacks that manipulate images. This is not a user-level command.
This program selects a random image, and puts it on the specified window or pixmap. This image might be a snapshot of the desktop; or a
frame captured from the system's video input; or a randomly-selected image from disk.
If only a window ID is specified, the image will be painted there. If both a window ID and a pixmap ID are specified, then the image will
be painted on the pixmap; and the window may be modified as a side-effect.
OPTIONS
xscreensaver-getimage reads the ~/.xscreensaver file for configuration information. It uses these settings:
grabDesktopImages
Whether it is acceptable to grab snapshots of the desktop. The security paranoid might want to turn this off, to avoid letting people
see (but not touch!) your desktop while the screen is locked.
grabVideoFrames
Whether it is acceptable to grab frames of video from the system's video input. Grabbing of video is done by invoking the xscreen-
saver-getimage-video(1) program.
chooseRandomImages
Whether it is acceptable to display random images found on disk. Selection and loading of images is done by invoking the xscreensaver-
getimage-file(1) program.
imageDirectory
When loading images from disk, this is the directory to find them in. The directory will be searched recursively for images.
It may also be the URL of an RSS or Atom feed, in which case a random image from that feed will be selected instead. The contents of
the feed will be cached locally and refreshed periodically as needed.
If none of the three options are set to True, then video colorbars will be displayed instead.
BUGS
When grabbing desktop images, the window argument will be unmapped and have its contents modified, causing flicker. (This does not happen
when loading image files or video frames.)
