Comment (by sandreas):
Thanks for taking a look. Maybe it would be possible to get both values
("before edit" list value and "after edit list" value).
I would also like to point out, that even with the ffmetadata there is no
way to get the exact duration in milliseconds from a command line.
Is there a workaround, that I'm not aware of?
