capture_output was introduced in Python 3.7 version https://stackoverflow.com/questions/53209127/subprocess-unexpected-keyword-argument-capture-output/53209196

@kenshohara should Python 3.7 be a requirement?

replace line 17 in generate_videos_jpgs.py with p = subprocess.run(ffprobe_cmd , stdout=PIPE, stderr=PIPE) and also dont forget to add (from subprocess import PIPE) at the begining of this file
