Comment (by Kdmeizk):
Since mkvmerge is the possible reference here, I checked with the version
9.7.1.
With {{{mkvmerge -o out.mkv in.mkv}}}, there is no '''DURATION''' fields
while ffmpeg does it.
But the main information I retained is in their documentation
(https://mkvtoolnix.download/doc/mkvmerge.html#d4e535), you can see for
the {{{--enable-durations}}} option:
[[BR]]
> Write durations for all blocks. This will increase file size and does
not offer any additional value for players at the moment.
[[BR]]
So if {{{-map_metadata -1}}} is not the original way to avoid the write of
these '''DURATION''' fields (that I believe I understood from your
answer), is it possible to do something (you or me) to avoid the use of
mkvmerge in addition to ffmpeg to fix this problem?
