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
  
  
  * MKVToolNix GUI: the key combination Ctrl+Shift+Space will now toggle the
    selection of the current item in all tree views where multiple selections
    are allowed. Implements #1983.
  * MKVToolNix GUI: chapter editor: added the extension `*.cue` (for cue sheet
    files) to the "open chapter file" dialog.
  * mkvmerge: cue sheet parser: if the cue sheet contains a non-empty `TITLE`
    entry and if no other segment title has been set yet, then the segment title
    will be set to the cue sheet's `TITLE` value. Implements #1977.
  * mkvmerge, MKVToolNix GUI (multiplexer): added an option `--no-date` that
    prevents the "date" field from being written to the segment information
    headers. Implements one half of #1964.
  * mkvpropedit, MKVToolNix GUI: header editor: added support for editing the
    "date" segment information field. Implements the other half of #1964.
  
  
  ## Bug fixes
  
  
  * MKVToolNix GUI: preferences → job actions, type "play audio file": the GUI
    will no longer clear the audio file name input if the user aborts the audio
    file selection dialog.
  * MKVToolNix GUI: preferences → job actions, type "play audio file", on
    Windows: the default "play audio" action was pointing to the wrong
    directory. Existing configurations with such a wrong path will be fixed
    automatically upon starting the GUI. Fixes #1956.
  * mkvmerge: HEVC/h.265 parser: fixed the superfluous copying of the
    `bitstream_restriction_flag` and its dependent flags in the VUI parameters
    of the sequence parameter sets if the timing information is present,
    too. This fixes #1924 properly, and it also fixes #1958.
  * mkvmerge: MPEG TS reader, AAC parser: the MPEG TS reader will now force the
    AAC parser to use the multiplex mode that the MPEG TS reader has detected
    (e.g. LOAS/LATM). This prevents the AAC packetizer from mis-detecting it in
    its own attempt to identify the mode. Fixes #1957.
  * mkvmerge: MPEG TS reader: valid MPEG transport streams that start with an
    h.264/h.265 start code (e.g. a file created by cutting at an arbitrary
    position) were not recognized as a supported file type.
  * mkvmerge: MPEG TS reader: fixed a potential read access from invalid memory
    addresses in the code parsing the program map table (PMT).
  * mkvmerge: MPEG TS reader: if packets are encountered that belong to a PID
    not listed in the program map table (PMT), mkvmerge will attempt to
    determine their type and codec from the content. This supported content
    types are AAC (ADTS only) and AC-3. Fixes #1980.
  * mkvmerge: MP4 reader: fixed finding and parsing the `colr` atom if there are
    more than one video extension atoms and the `colr` atom is not the first
    one.
  * mkvmerge: MP4 reader: the `nclx` colour type of the `colr` atom is now
    recognized, too (as defined by ISO/IEC 14496-12, "ISO base media format").
  * configure: fixed configure aborting if a `moc`, `uic`, `rcc` or `qmake`
    binary is found, but the binary's version is too old. Fixes #1979.
  
  
  
  
  # Version 11.0.0 "Alive" 2017-04-22
  
  
  ## New features and enhancements
  
  
  * mkvmerge: FLAC reader: added support for handling embedded pictures as
    attachments. Implements #1942.
  * mkvmerge: MP4 reader: merged pull request #1804 adding support for parsing
    the "COLR" atom and including its values as track headers.
  * MKVToolNix GUI: watch jobs: the user can now have the GUI execute an action
    once as soon as the current job or the whole queue finishes. The actions are
    the same ones that can be configured to be run automatically after job or
    queue completion.
  * MKVToolNix GUI: implemented several built-in actions that can be executed
    either on special events or once via the "watch jobs" tool. These are:
    playing an audio file (implemented for all operating systems); hibernating,
    sleeping and shutting down the computer (only implemented for Windows and
    for Linux systems using systemd).
  * MKVToolNix GUI: multiplex tool: added a new option for what to do after
    starting to multiplex/adding to the job queue: "close current settings" will
    close the current multiplex settings without opening new ones.
  
  
  ## Bug fixes
  
  
  * mkvmerge: AAC parser: fixed mis-detection of certain data as valid ADTS AAC
    headers resulting in memory allocation failures. Fixes #1941.
  * mkvmerge: AVC/h.264 parser: mkvmerge will now ignore bogus timing
    information in the sequence parameter sets (values indicating more than
    100000 progressive frames per second). Fixes #1946.
  * mkvmerge: AVC/h.264 & HEVC/h.265 parsers: all trailing zero bytes will now
    be removed from NALUs. Fixes #1952.
  * mkvmerge: HEVC/h.265 parser: fixed copying the `bitstream_restriction_flag`
    and all dependent fields in the VUI parameters of the sequence parameter
    sets. Fixes #1924.
  * mkvmerge: HEVC/h.265 parser: fixed the calculation of the number of
    parameter set arrays in the HEVCC data structure stored in
    CodecPrivate. Fixes the video-related part of #1938.
  * mkvmerge: HEVC/h.265 parser: fixed writing superfluous and uninitialized
    bytes at the end of the HEVCC data structure stored in CodecPrivate. Another
    fix for the video-related part of #1938.
  * mkvmerge: HEVC/h.265 parser: fixed the assumption that the HEVCC data
    structure always includes arrays for all parameter set types (VPS, SPS, PPS
    and SEI), and that the order is always VPS → SPS → PPS → SEI. Instead now
    only the arrays actually present are parsed, and they can be in any order.
    This fixes mkvinfo's output for Matroska files created from files such as
    the one from #1938.
  * mkvmerge: AVC/h.264 packetizer: when reading a framed track (e.g. from
    Matroska or MP4 files), specifying a default duration as fields (e.g. `50i`)
    would result in double the actual duration for each frame and the track's
    default duration header field. Fixes #1916.
  * mkvmerge: Matroska reader: invalid track language elements are now treated as
    if they were set to `und` = "undetermined". See #1929 for context.
  * mkvmerge: MPEG TS reader, AAC: mkvmerge will now require five consecutive
    AAC headers with identical parameters before track type determination is
    considered valid. This avoids false positives and consequently wrong track
    parameters. Fixes the audio-related part of #1938.
  * mkvmerge: fixed an endless loop in certain circumstances when splitting by
    `parts` or `parts-frames` and the start of the file is discarded. Fixes
    #1944.
  * MKVToolNix GUI: multiplexer tool: the "show command line" dialog will no
    longer include the mkvmerge executable's location as the first argument for
    the two "MKVToolNix option files" escape modes. Fixes #1949.
  * MKVToolNix GUI, header editor: empty track language elements are now treated
    the same as those set to invalid ISO 639-2 codes: as if they were set to
    `und` = "undetermined". See #1929 for context.
  
  
  ## Build system changes
  
  
  * bug fix: configure now looks for the `strings` binary by using the
    `AC_CHECK_TOOL()` autoconf macro. That way it will be found in multiarch
    setups, too. Fixes #1923.
  * bug fix: the environment variable USER_CXXFLAGS was accidentally removed
    from the compiler flags in release 9.8.0. It's been re-added. Fixes #1925.
  * The `.desktop` files have been renamed to
    `org.bunkus.mkvtoolnix-gui.desktop` and `org.bunkus.mkvinfo.desktop`. This
    allows Wayland compositors to associate the correct icons with running
    applications for e.g. task switchers. Fixes #1948.
  * Qt's multimedia component is required for compilation of the GUIs since
    version 11.0.0.
