Download MKVToolnix 81.0.0

MKVToolNix, a powerful and versatile toolkit for managing Matroska multimedia files, has released its latest version 81.0.0. This new release brings several significant changes that users need to be aware of. In this article, we will explore the key updates and what they mean for you.

One of the most notable changes is the way MKVToolNix handles information retrieval. Previously, users could access information about available updates through the MKVToolNix website. However, with the new release, users can now switch to retrieving this information directly from the website in JSON and XML file formats.

For those who use the command-line tools, there is a slight change. The option `-check-for-updates` has been removed from all command-line tools, except for the GUI which will continue to perform online checks for updates as before. This means that users of the command-line tools need to adjust their workflow accordingly.

Another important update is the conversion to a new JSON option file format. Users who rely on the old proprietary format used by MKVToolNix are advised to switch to the new format, which can be achieved using mkvmerge's JSON identification output with the options `-identification-format json -identify…`.

Furthermore, several options and features have been deprecated in this release and will be removed at the start of 2018. This includes options such as `-identify-verbose`, `-identify-for-gui`, `-identify-for-mmg`, and `-identification-format verbose`. It is essential for users to migrate away from these deprecated features to ensure continued compatibility with future releases.

Lastly, a bug fix has been implemented in the MKVToolNix GUI multiplex tool. Under certain circumstances, the GUI was creating invalid JSON files when starting to multiplex, resulting in an error message. This issue has been resolved, and users can now enjoy a more stable and reliable experience when using the multiplex tool.

In conclusion, the latest release of MKVToolNix 81.0.0 brings several important changes that users need to be aware of. By understanding these updates, you can ensure a smooth transition to the new version and take full advantage of its features and improvements.
