Comment (by Kdmeizk):
I don't really understand what you mean with "use-case".
I'm using one of the latest builds from https://ffmpeg.zeranoe.com/builds/
And the result from MediaInfo:
{{{

It can calculate or retrieve the duration one time, that's why the second
'''DURATION''' is not useful for me, and impossible to delete.
