Detect motion in VLC video?

Question

VLC

I do

vlc.exe --video-filter=motiondetect "файл" --verbose=2 --file-logging --logfile=log.txt

Getting everything good
Adding speedups

vlc.exe --video-filter=motiondetect "файл" --verbose=2 --file-logging --logfile=log.txt --rate=31.25

It is not clear which motiondetect refers to which frames

Those. support says "You have to patch VLC at the line of the log to know the corresponding timestamp."
What does it mean?

Answer 1

he meant that you can change the VLC player code so that it makes timestamps in the log
