How to take a screenshot every n second?

  • 772

What software can I use to take screenshots with a set interval? I'd like to take screenshots every 2 second or so. Command-line and GUI are both ok.

I'd prefer software that can also resize and compress each screenshot.

  4. As per an edit to your question:

    import threading
    import os

    def capture(i):
        i += 1
        threading.Timer(2.0, capture, [i]).start()
        fill = str(i).zfill(5)
        os.system("scrot scrot-%s.jpg" % fill)
        os.system("streamer -o streamer-%s.jpeg -s 320x240 -j 100" % fill)

    capture(0)

  5. If you want to control the number of screenshots and/or maybe their names, you could do:

    for i in {1..10};do
    scrot $i'.png' && sleep 1;
done

    Cheers!
