Just for curiosity I installed mediainfo and tested:
mediainfo --parsespeed=1 2022-01-20_07Testvideo.mp4 | grep Duration
Duration : 43 min 31 s
Duration : 43 min 31 s
Duration : 43 min 31 s
So it creates 3 instances of the duration output...
Have to add | tail -n 1 to the end to get one item only.
I think the ffprobe solution is what I'd choose, does not require installing any
additional program too.
