Using mediainfo to extract the "Recorded_Date" from a video file, and using it to set the timestamp of the file.


  for f in *.mov; do t=$(mediainfo --Inform="General;%Recorded_Date%" "$f"); echo "$f $t"; [ -z "$t" ] && continue; t2=$(perl -e '$_=shift; s/[- :]//g; s/(\d\d)\.\d+$/.$1/; print' "$t"); touch -t "$t2" "$f" && echo "ok"; done
