I have a video recorded from an IP surveillance camera. Link: https://www.dropbox.com/s/4gtcbge08nlv9rx/motion0.mp4?dl=0
I want to extract motion info, so I use following command: ffmpeg -vismv pf -i motion0.mp4 -y output.mp4 This converts the original file, marking motion vectors as well (as required). But the end result is: it is marking stationary places as noise as well (random arrows everywhere). I want to know why this is happening. I have already tried this command with other video(s), and random noise does not show there. Any help is much appreciated...
