How to write a bash script (a script that will collect images in a day and encode into a video.)?

Question

linux

There is a site that changes the image on the site every half an hour. What methods are needed to write a script that collects one image per day and encodes it into a video?

Answer 1

If you need bash, then curl / wget to get the image (if the url does not change or is predictable) and ffmpeg to encode to video. Or ImageMagick to assemble to gif.
Or python and Beautiful Soup for site parsing, ffmpeg or cv2 for assembling images into videos. Or imageio, or pillow to assemble into a gif.
