MKVToolnix

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: chapters: mkvmerge can now read chapters from DVDs if the user
    specifies the path to a DVD folder structure via the `--chapters …`
    parameter. By default chapters from the first title will be imported. This
    can be changed by append `:<title number>` to the file/directory name in the
    `--chapters …` argument, e.g. `--chapters /srv/dvds/BigBuckBunny/VIDEO_TS:3`
    This feature requires mkvmerge to have been built with the `libdvdread`
    library.  Part of the implementation of #2808.
  * mkvmerge: added `--engage append_and_split_flac` that enables mkvmerge to
    append and split FLAC tracks, restoring pre-v45 behavior.  The resulting
    tracks will be broken: the official FLAC tools will not be able to decode
    them and seeking will not work as expected.
  * MKVToolNix GUI: multiplexer: added support for mkvmerge's new support for
    reading chapters from DVDs if both have been built with the `libdvdread`
    library. Part of the implementation of #2808.
  * MKVToolNix GUI: multiplexer: when deriving languages from file names the GUI
    will now look for simplified language names instead of the full ones
    (e.g. instead of looking for "Greek, Modern (1453-)" it would simply look
    for "Greek").
  * MKVToolNix GUI: multiplexer: the options in the "additional command-line
    options" dialog are now sorted alphabetically. Additionally the
    `--append-mode` option has been added as one of the only missing global
    options.
  * MKVToolNix GUI: chapter editor: the chapter editor can now read chapters
    from DVDs if MKVToolNix has been build with the `libdvdread` library. Part
    of the implementation of #2808.
  * MKVToolNix GUI: header editor: added an option in the preferences for
    displaying all date & time values in UTC instead of the local time
    zone. Implements #2814.
  
  
  ## Bug fixes
  
  
  * all: fixed a crash when using the `MTX_LOGGER=file` syntax for logging debug
    messages without specifying a file name to log to. It will now log to a file
    called `mkvtoolnix-debug.log` in the system's default temporary directory,
    as initially intended.
  
  
  ## Build system changes
  
  
  * The [`libdvdread`](https://www.videolan.org/developers/libdvdnav.html)
    library will be used if found via `pkg-config`. If it is found, support for
    reading chapters from DVDs will be enabled in `mkvmerge` and the MKVToolNix
    GUI. Part of the implementation of #2808.
  * Boost's Date/Time, Lexical Cast, Range, Range Adaptors, Tri-Bool, Variant
    libraries are not used anymore.
  * MKVToolNix now requires a C++ compiler & standard library that support the
    following features of the C++17 standard: "`std::variant`", "`std::gcd`".
    For the GNU Compiler Collection (gcc) this means v7 or newer; for clang it
    means v4 or newer — the same versions required by earlier MKVToolNix
    versions.
  * MKVToolNix now requires version 6.1.0 of fmtlib or later for the
    `fmt::to_string` function and bugfixes to the formatting of floating point
    numbers. If a system-wide version is installed that's older, the bundled
    copy will be used.
  * The bundled version of fmtlib has been updated to release 6.2.1.
