Description:

From the Official Site:
MKVToolnix is a set of tools to create, alter and inspect Matroska files under Linux, other Unices and Windows. They do for Matroska what the OGMtools do for the OGM format and then some.

With these tools one can get information about (mkvinfo) Matroska files, extract tracks/data from (mkvextract) Matroska files and create (mkvmerge) Matroska files from other media files. Matroska is a new multimedia file format aiming to become THE new container format for the future.

    ## New feature: IETF BCP 47 language tags

    * I've written up a [nice FAQ
      entry](https://gitlab.com/mbunkus/mkvtoolnix/-/wikis/Languages-in-Matroska-and-MKVToolNix)
      about the switch to using IETF BCP 47 language tags, how they interact with
      legacy language elements, how the programs actually behave and how to
      disable their use if necessary.
    * mkvmerge: IETF BCP 47/RFC 5646 language tags: mkvmerge will now accept full
      BCP 47 language tags for all options taking a language. mkvmerge will always
      write "LanguageIETF" track header elements. If the language tag contains a
      valid ISO 639-2 language code it will also set the legacy "Language" track
      header element to the included ISO 639-2 code. Part of the implementation of
      #2419.
    * mkvmerge: IETF BCP 47/RFC 5646 language tags: if present the "LanguageIETF"
      track header element will be reported as the `language_ietf` property in
      JSON identification mode. Part of the implementation of #2419.
    * mkvmerge: IETF BCP 47/RFC 5646 language tags in chapters: mkvmerge will now
      write "ChapLanguageIETF" elements when creating chapter atoms, either when
      reading the simple chapter format or when generating chapters due to the
      `--generate-chapters` command line option. Part of the implementation of
      #2419.
    * mkvmerge: IETF BCP 47/RFC 5646 language tags in tags: mkvmerge will now
      write "TagLanguageIETF" elements when creating "simple tag" elements, either
      when reading tag XML files or when generating them. Part of the
      implementation of #2419.
    * mkvmerge: IETF BCP 47/RFC 5646 language tags: added an option
      `--disable-language-ietf` that causes mkvmerge to only write the legacy
      language elements.
    * mkvmerge, mkvpropedit, MKVToolNix GUI's chapter editor: IETF BCP 47/RFC 5646
      language tags in chapters: when reading XML chapter files the programs will
      now add "ChapLanguageIETF" elements for atoms that don't contain them. The
      values are derived from existing "ChapterLanguage" elements. Part of the
      implementation of #2419.
    * mkvpropedit: IETF BCP 47/RFC 5646 language tags: setting/deleting the track
      language now acts on both the old language element as well as the
      "LanguageIETF" track header element. Part of the implementation of #2419.
    * mkvpropedit: IETF BCP 47/RFC 5646 language tags: added an option
      `--disable-language-ietf` that causes mkvpropedit to apply changes to the
      `language` track header property only to the legacy language track header
      element.
    * mkvinfo: IETF BCP 47/RFC 5646 language tags: added support for the
      "LanguageIETF" track header element. Part of the implementation of #2419.
    * MKVToolNix GUI: multiplexer: added full support for IETF BCP 47/RFC 5646
      language tags for both track and chapter languages. Part of the
      implementation of #2419.
    * MKVToolNix GUI: chapter: added full support for IETF BCP 47/RFC 5646
      language tags for chapter languages. Part of the implementation of #2419.
    * MKVToolNix GUI: header editor: added full support for IETF BCP 47/RFC 5646
      language tags for track header languages. The header editor allows editing
      of the legacy language elements and the IETF BCP 47 language elements
      independent of each other. Part of the implementation of #2419.

    ## Other new features and enhancements

    * mkvmerge: the chapter generation mode `when-appending` now also works with
      the splitting modes `parts:` & `parts-frames:` when using the `…,+…` syntax
      for appending other sections of the source file to the same destination
      file. Implements #2898.
    * MKVToolNix GUI: multiplexer: the file selection dialogs now include the
      extension `.dtsma` for DTS files. Implements #2901.
    * mkvmerge: MP4 reader: sped up parsing MP4 DASH files with a lot of segments
      (`trun` atoms) quite a bit. Part of the fix of #2900.
    * The PCRE2 regular expression library is now used instead of `std::regex` for
      big performance improvements in all places where regular expressions are
      used for parsing big chunks of text, e.g. in the subtitle parsers. Part of
      the fix of #2899.
    * all programs: Windows: all programs now support long file names on Windows
      10 release 1604 if they're turned on in the registry. Implements #2916.

    ## Bug fixes

    * MKVToolNix GUI: preferences: under certain conditions changing the selected
      entry in the page tree on the left did not cause the page shown on the right
      to be updated. Fixes #2895.
    * mkvmerge: splitting text by a fixed string (e.g. `,`) is now done by using
      `std::string.find()` instead of using a regular-expression-based text
      splitting function, greatly improving its performance. Part of the fix of
      #2899.
    * mkvmerge: mkvmerge will now read-buffer file I/O when probing text file
      formats which increases its speed significantly on Windows. Part of the fix
      of #2899.
    * mkvmerge: MP4 reader: fixed handling of `tkhd` atoms of version 1. Fixes
      #2900.

    ## Build system changes

    * The PCRE2 library (the 8-bit variant) is now required.
