Почему-то для многих .mkv файлов mediainfo показывает данные, которые не стыкуются между собой. Для разных фильмов из разных мест и т.д. При этом если пересобрать через mkvtoolnix, в новом файле данные начинают стыковаться.
Вот пример:

Duration : 1 h 38 min
Bit rate : 15.8 Mb/s
Что соответствует размеру дорожки в 10.8+ GiB.
Но далее мы почему-то видим:
Stream size : 10.6 GiB (89%)
То есть, что-то не то.
Подумал, может где что округляется не так… Но почему тогда чинится, если прогнать через mkvmerge, добавив, например, аудиодорожку другую?
В итоге догадался глянуть в документацию и узнал про ключ --fullscan у mediainfo. Там уже есть точные значения:

Имеем теперь точную продолжительность и точный битрейт, можем посчитать поточнее:
5913.372 * 15750000 / 8 = 11641951125 byte
5913.372 * 15750000 / 8 / 1024 / 1024 / 1024 ≈ 10.842411895282567 GiB
Всё ещё 11641951125 или 10.8 GiB. Откуда тогда берётся вот это:
Stream size : 11386383834
Stream size : 10.60 GiB
Есть какие-нибудь идеи?
И есть ли какие-то альтернативы mediainfo, которые выдают правильную инфу?
