[FFmpeg-devel] Why the tag “DURATION” is a necessity in Matroska files?

[21naown at gmail.com]

Hello,


I would like to know why the tag “DURATION” in Matroska files (.mkv) is 
a necessity? Even mkvmerge lets the choice to use it or not with 
“--enable-durations”, in addition it is written “Write durations for all 
blocks. This will increase file size and does not offer any additional 
value for players at the moment.” (source 
https://mkvtoolnix.download/doc/mkvmerge.html#d4e535).

Thank you for your understanding.

Best regards.
