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 features and enhancements

    * mkvmerge, mkvpropedit, MKVToolNix GUI: IETF BCP 47 language tags: added
      missing support for UN M.49 regions for which there are no corresponding ISO
      3166 alpha codes. This enables language tags such as `es-419` = Spanish in
      Latin America and the Caribbean. Implements #2919.
    * MKVToolNix GUI: IETF BCP 47 language tags: the text in the widget displaying
      the current language & the corresponding edit button is now displayed like a
      link (depending on the theme: different color & underlined), making it
      clearer that not just the edit button can be clicked but the text, too.

    ## Bug fixes

    * mkvmerge: AV1 parser: fixed mkvmerge crashing after uncaught exceptions due
      to certain data conditions. Found by fuzzying.
    * mkvmerge: AV1 packetizer: the duration of frames wasn't set properly. When
      appending AV1 IVF or OBU files this meant that the last frame of the Nth
      file and the first frame of file N+1 had the same timestamp. Fixes #2937.
    * mkvmerge: DTS reader: fixed handling of buffers with an odd length when
      byte-swapped DTS is detected so that mkvmerge doesn't abort with a failed
      assertion. Found by fuzzying.
    * mkvmerge: h.264/AVC and h.265/HEVC elementary stream readers: mkvmerge will
      no longer claim to recognize data that looks like AVC or HEVC but with
      invalid video width/height values as that lead to failed assertions in
      libEBML later. Found by fuzzying.
    * mkvmerge: h.265/HEVC parser: fixed mkvmerge aborting after uncaught
      exceptions due to certain data constellations found by fuzzying.
    * mkvmerge: IVF reader: fixed mkvmerge crashing with a "division by zero"
      error due to certain data conditions. Found by fuzzying.
    * mkvmerge: fixed mkvmerge aborting with a "division by zero" error due to the
      timestamp scaling factor being 0 after handling certain data constellations
      found by fuzzying.
    * mkvmerge: track statistics: fixed a "division by zero" error when the
      content's shorter than 1ms. Found by fuzzying.
    * mkvmerge, mkvinfo, mkvextract, mkvpropedit: Matroska access class: fixed an
      invalid memory access under certain data conditions. Found by fuzzying.
    * MKVToolNix GIU: IETF BCP 47/RFC 5646 language tags: the GUI will no longer
      open the language dialog when clicking on a disabled language display
      widget.
    * MKVToolNix GUI: IETF BCP 47 language tags: the "variants" combo-boxes were
      not populated even when the language tag was valid and contained at a
      variant. Fixes #2923.
    * MKVToolNix GUI: IETF BCP 47 language tags: when no language is selected, at
      least one of the other components (extended subtags, region, or variants)
      has something selected and "private use" is not empty, the GUI would claim
      this to be a valid tag, which it isn't. Fixes #2924.
    * MKVToolNix GUI: multiplexer: when the tracks/chapters/tags selection changes
      from "at least one entry selected" to "no entry selected", the input
      controls will be reset to their default state and not just disabled. Fixes
      #2927.

    ## Build system changes

    * `configure` now checks for the presence of the a system-wide installed copy
      of the JPCRE2 C++ wrapper library for the PCRE2 library and uses that if
      it's new enough (at least v10.32.1). If not, the bundled version will be
      used as a fallback. Implements #2929.
