Linux Shell Scripting Cookbook - Third Edition

How it works...

This script is more complex than the ones we've looked at so far. It uses seven command-line arguments to define the input image, a prefix to use for the output files, the width and height for the intermediate images, and the starting offset into the original image.

Within the for loop, it creates a set of image files and stores the names in a file named tmpFiles. Finally, the script uses mencoder to merge the extracted image files into an MPEG video that can be imported into a video editor such as kdenlive or OpenShot.
