Ability to track progress of an ffmpeg command

Created by: cdeepakroy

Is there a way to track a progress after running an ffmpeg?

For example, below is what i would like to do:

import ffmpeg
ffmpeg.input('test.mp4').output('frame_%06d.jpg').run()

This command writes each frame of a video as an image to disk.

At the very least it would be great if we could see the output generated by running ffmpeg on commandline ffmpeg -i test.mp4 %06d.png -hide_banner
