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.


Supported File Formats:

Output Files: MKV

OS Compatibility:

Windows XP/Linux/Unix/Mac OS/Windows Vista

    ## Important notes

    * build system: the included version of the "drake" build tool has been
      removed. Since Ruby 2.1 rake has supported parallel builds, too. The
      MKVToolNix build system has been adjusted to enable parallel builds by

    ## New features and enhancements

    * mkvmerge: VobSub in Matroska: mkvmerge will now create and use a default
      index for VobSub tracks read from Matroska files that are missing their
      CodecPrivate element (which normally contains said index). Implements #1854.
    * GUI: added checks for several common problems with the installation. These
      checks will be executed when the GUI starts, and any problems will be
      reported to the user.
    * mkvmerge: added the ISO 639-2 language codes "qaa" and "qad" (both are
      titled "reserved for local use") as both are used often in France. See #1848
      for more information.
    * mkvmerge: the JSON identification result now includes a track's codec delay
      if set (only for Matroska source files). The JSON schema version has been
      bumped to 6.
    * mkvmerge: MPEG TS: added a workaround for files where the subtitle packets
      are multiplexed properly, but where their timestamps are way off from the
      audio and video timestamps. Implements #1841.
    * mkvmerge: added support for Digital Video Broadcasting (DVB) subtitles
      (CodecID `S_DVBSUB`). They can be read from MPEG transport streams and from
      Matroska files. Implements #1843.

    ## Bug fixes

    * mkvmerge: MP4 reader: when an MP4 file contained fewer entries for
      timestamps than frames (which they never should), mkvmerge would use 0 as
      the timestamp for all the other frames. This resulted in effects such as the
      last frame of an output file having a timestamp of 0 and in split files
      having a much longer duration than they should have. Fixes #1847.
    * GUI: the cache cleanup process that's run automatically when the GUI starts
      no longer blocks file identification until it is finished. Additionally the
      process will only be run once per release of MKVToolNix. Fixes #1860.
    * GUI: certain failures during file identification that can be traced to
      broken installations (e.g. mkvmerge being too old) won't be stored in the
      cache anymore. Without this fix the GUI would still use the cached failed
      identification result even though the underlying might have already been
    * mkvmerge: fixed that the error message "not enough space on disk" was shown
      twice on some operating systems. Fixes #1850.
    * mkvmerge, Matroska: if a codec delay is set for a track in the input file,
      it is kept. Fixes #1849.
    * GUI: multiplexer: changing default values in the preferences (e.g. the
      default track language to set) did not affect files whose identification
      results had already been cached.
    * mkvmerge, MP4: fixed detection of MP3 audio when the object type ID in the
      ESDS signals MP2 and the track headers have invalid values for number of
      channels or sampling frequency. Fixes #1844.

    ## Build system changes

    * nlohman json-cpp: configure now looks for a system-wide installed version of
      the nlohmann json-cpp header-only library. If one is found, it is used;
      otherwise the included version will be used. Implements #1858.
    * If MKVToolNix is built with rake v10.0.0 or newer, its "multitask" feature
      will be turned on allowing automatic parallel builds.
    * CURL is no longer used by MKVToolNix and is therefore not required
      for building anymore.

    ## Other changes

    * GUI: the update check now uses Qt's networking classes instead of CURL.
    * The command line option "--check-for-updates" has been removed, even
      though the deprecation warning in release 9.7.0 stated that it would
      be removed in 2018.
