Мне было интересно, в чем разница между типом метаданных, возвращаемых mdlsи передаваемых mediainfo. Почему они разные? Например, почему дата создания отличается в одном файле?
Спасибо!

There is no creation date info from you MediaInfo output. You have "only" recorded date (when the source was recorded), encoded date (when someone encoded the source file to another format), the tagging date. None of them is the file creation date (the date when the file was created on your local fie system).
Beware of the meaning of each field.
