* Fri May 01 2020 Luigi Baldoni <>
  - Update to version 46.0.0
    New features and enhancements:
    * mkvmerge: when splitting, the placeholder `%c` can be used
      in the destination file name. It'll be replaced by the name
      of the first chapter in the file. Implements #2791.
    * mkvmerge: when reading MPLS playlists mkvmerge will include
      a tag named `SOURCE_ID` in the track's statistics tags that
      conveys the fact that the source was a Blu-ray and what the
      track's ID was in the source container. When reading Matroska
      file existing `SOURCE_ID` tags will be kept. The format used
      is the same format MakeMKV uses. Implements #2774.
    * mkvmerge: for audio-only files mkvmerge will now write a cue
      entry every 500ms instead of every 2s.
    * MKVToolNix GUI: job actions: split up the option "execute
      when the job finishes successfully or with warnings" into two
      separate options: "…when finishes successfully" and "…when
      exits with warnings". Implements #2798.
    Bug fixes:
    * mkvmerge: Matroska reader: when regenerating UIDs for
      chapters mkvmerge will now fix referencing tag chapter UID
      targets to have the same values. Fixes #2804.
    * mkvmerge: MP4 reader: fixed a crash that could potentially
      happen while trying to identify H.265/HEVC tracks.
    * mkvmerge: MP4 reader: when reading H.265/HEVC tracks without
      a frame offset table (`ctts` atom) present, mkvmerge did not
      parse the `hevcC` structure correctly in certain cases,
      causing no video frames to be output at all or the output not
      being playable. This fixes #2782, a bug introduced in v45.
    * mkvmerge: MPLS handling/MPEG TS reader: timestamp
      restrictions as given in an MPLS file were only honored for
      the first play item, not for subsequent play items. For those
      play items the whole referenced file was always copied. Part
      of the fix of #2789.
    * mkvmerge: MPLS handling/MPEG TS reader: under certain
      circumstances mkvmerge copied one frame too many before
      switching to the next play item. Part of the fix of #2789.
    * mkvmerge: for audio-only files cues will only be created for
      I frames (important for e.g. TrueHD where decoding can only
      start on a sync frame). Fixes #2790.
    * MKVToolNix GUI: fixed a crash that happened when closing the
      preferences after having closed at least one multiplexer tab.
      Fixes #2785.
* Sat Apr 04 2020 Luigi Baldoni <>
  - Update to version 45.0.0
    New features and enhancements:
    * mkvmerge: mkvmerge has never supported appending & splitting
      FLAC audio tracks. mkvmerge will now emit error messages
      when the user attempts either instead of continuing and
      creating invalid FLAC tracks.
    * MKVToolNix GUI: added an option in the preferences to turn
      on eliding text on tab headers. If enabled, tab names will be
      shortened so that all tab headers fit into the window's
      width. Implements #2768.
    * MKVToolNix GUI: added an option in the preferences to
      disable all tooltips.
    * MKVToolNix GUI: multiplexer: if the file identification
      fails due to a JSON parser error, the output generated by
      `mkvmerge` will be output to `STDERR` allowing insight into
      what's gone wrong.
    * MKVToolNix GUI: multiplexer: if an error occurs during file
      identification, the name of the processed file will be
      mentioned in the error message.
    * MKVToolNix GUI: multiplexer: if an error occurs during
      identification of multiple files, the GUI will ask the user
      whether to continue or abort the identification process.
      Implements #2778.
    * MKVToolNix GUI: job queue: added an option in the
      preferences for removing completed jobs when exiting the
      program depending on their status. Implements #2769.
    Bug fixes:
    * mkvmerge: H.265/HEVC packetizer: fixed changing the NALU
      size length, it was using the wrong offset into the `hevcC`
    * mkvmerge: MP4 reader: fixed calculating the duration of
      video tracks that only contain a single frame. Fixes #2747.
    * mkvmerge: MP4 reader: if there's no frame offset table
      (`ctts` atom) present for H.265/HEVC video tracks, mkvmerge
      will determine the timestamp order itself instead of relying
      on the timestamps in the MP4 being in the presentation order
      required by Matroska. Fixes #2777.
    * MKVToolNix GUI: multiplexer: when using the title as part of
      the destination file name (both automatically as well as
      using the "copy title to destination file name" function) all
      characters that aren't valid in a file name are replaced by
    * MKVToolNix GUI: multiplexer: the "copy title to destination
      file name" function was broken when the "make file name
      unique" option in the preferences was disabled. In that case
      the file base name was removed regardless of what the title
      was set to at the time.
    * MKVToolNix GUI: multiplexer: when adding Blu-ray playlists
      the GUI used to only look for the English version of the disc
      library information (title & cover images). Now the GUI will
      present all disc library entries in the "select playlist to
      add" dialog & let the user chose which one to use (if any).
      Fixes #2765.
    * MKVToolNix GUI: multiplexer, info tool: fixed the "warn
      before overwriting" check wrt. jobs creating the same file.
      Fixes #2758.
* Mon Mar 09 2020
  - Update to version 44.0.0
    New features and enhancements:
    * MKVToolNix GUI: header editor: the attachments can now be
      reordered via drag & drop. Implements #2753.
    Bug fixes:
    * mkvmerge: Matroska reader: when encountering certain errors
      in the track headers such as the codec ID not being present
      mkvmerge will simply skip those tracks instead of exiting
      with an error. Fixes #2737.
    * MKVToolNix GUI: multiplexer: the "ask before overwriting"
      functionality did not look for the correct file names when
      splitting was active. Fixes #2741.
* Mon Jan 27 2020 Luigi Baldoni <>
  - Update to version 43.0.0
    New features and enhancements:
    * MKVToolNix GUI: using one of the command line options
      `--info`, `--edit-headers` or `--edit-chapters` will make
      the GUI select the corresponding tool on startup even if no
      further file name is given. Implements #2723.
    * MKVToolNix GUI: multiplexer: added a setting in the
      preferences for changing the location of the MediaInfo
      executable for when the user accidentally selected the wrong
    Bug fixes:
    * mkvmerge: AVC/h.264 parser: the order of the NALUs before
      each key frame was sometimes wrong: mkvmerge wrote SPS & PPS
      after SEI NALUs. Now SPS & PPS NALUs are always written
    before the other NALUs. Patch by Torsten Hauska. Part of the
    implementation of #2709 and part of the fix of #2250.
    * mkvmerge: AVC/h.264 parser: when additional SPS or PPS NALUs
      (with IDs that haven't been seen so far) are found
      mid-stream, mkvmerge will prepend all following key frames
      with all current valid SPS & PPS NALUs (just like when SPS &
      PPS NALUs are overwritten mid-stream). Part of the fix of
    * mkvmerge: MPEG TS reader: fixed detection of MPEG-1/2 video
      tracks consisting of very few frames. Fixes #2732.
    * mkvmerge: Ogg Opus reader: fixed the handling of Ogg Opus
      streams that contain a just one Ogg page (`mkvmerge` aborted
      with an exception). Fixes #2722.
    * MKVToolNix GUI: multiplexer: dragging & dropping XML files
      with chapters or tags to the GUI's window was broken in v42.
      Instead of adding the file names to the appropriate input
      boxes the GUI was running mkvmerge for file identification
      purposes which then failed. Fixes #2718.
* Thu Jan 02 2020 Luigi Baldoni <>
  - Update to version 42.0.0
    New features and enhancements:
    * mkvmerge: added an option for creating byte-identical files:
      `--deterministic <seed>`. Part of the implementation of
    * mkvmerge: Matroska reader: mkvmerge will remove the `icpf`
      atom headers if they're present in frames read from Matroska
      files. Implements #2692.
    * mkvmerge: MP4 reader: ALAC tracks: the number of channels,
      sampling frequency and bit depth are now taken from the
      bitstream in order to fix bogus values on the container level.
      Implements #2714.
    * mkvpropedit: when changing track UIDs the referring elements
      in existing chapters & tags will be updated automatically,
      too. Part of the implementation of #2700.
    * mkvinfo: when the option `-p`/`--hex-positions` is used,
      element positions will be output regardless of the verbosity
      level. Part of the implementation of #2713.
    * mkvinfo: added the option `-P`/`--positions` for showing the
      position of each element in decimal regardless of the
      verbosity level used. Part of the implementation of #2713.
    * mkvinfo: added the option `-o`/`--continue` for continuing
      processing when the first cluster is encountered regardless
      of the verbosity level used. Part of the implementation of
    * mkvinfo: added the option `-a`/`--all` for outputting all
      sub-elements (even cues & seek head entries) and not
      stopping at the first cluster regardless of the verbosity
      level used. Part of the implementation of #2713.
    * MKVToolNix GUI: multiplexer: added an option in the
      preferences for disabling adding cover images from Blu-ray
      discs. Implements #2693.
    * MKVToolNix GUI: multiplexer: added mkvmerge's new
      `--deterministic` option in the "additional command-line
      options" dialog. Part of the implementation of #2698.
    * MKVToolNix GUI: header editor:: when changing track UIDs the
      referring elements in existing chapters & tags will be
      updated automatically, too. Part of the implementation of
    Bug fixes:
    * mkvmerge: HEVC ES parser: fixed a bug in the slice parser
      calculating the size of a field which in turn could have led
      to the slice's type being read wrong. Patch by Torsten
      Hauska. Fixes #2710.
    * mkvmerge: Matroska reader: fixed a segmentation fault when
      trying to read a file that uses header removal compression
      but no removed bytes are present in the track headers. Fixes
    * mkvmerge: MPEG elementary stream parser: fixed an invalid
      memory access and use of uninitialized memory that could
      happen under certain circumstances. Fixes #2690.
    * mkvmerge: RealMedia reader: fixed a division by zero when
      all audio timestamps were zero. Fixes #2689.
    * mkvmerge: RealMedia reader: fixed an invalid memory access
      in the video frame assembly code triggered by invalid data
      in the file. Fixes #2691.
    Build system changes:
    * `std::optional` (C++17 feature) is now used instead of
    * `std::regex` is now used instead of `boost::regex`.
    Other changes:
    * New man page translations into French, Italian, Russian and
      Chinese Traditional have been added.
* Fri Dec 06 2019 Luigi Baldoni <>
  - Update to version 41.0.0
    New features and enhancements:
    * mkvmerge: Matroska reader: Vorbis tracks: stream comments
      (aka Vorbis comments) will be converted to Matroska
      attachments (for cover arts) and Matroska track tags (for
      other comments). Additionally the stream comments will be
      removed from Vorbis headers.
    * mkvmerge: MP4 reader: added support for reading Opus audio
      from MP4 files. Part of the implementation of #2673.
    * mkvmerge: MP4 reader: added support for reading VP9 video
      from MP4 files. Part of the implementation of #2673.
    * mkvmerge: Ogg reader: Vorbis, Opus & VP8 streams: stream
      comments (aka Vorbis comments) will be converted to Matroska
      attachments (for cover arts) and Matroska track tags (for
      other comments). Additionally the stream comments will be
      removed from Vorbis headers.
    * mkvmerge: WAV reader: added support for reading RF64 files.
    * MKVToolNix GUI: multiplexer: the list of predefined track
      names is now split up into three lists, one for each track
      type (audio, video & subtitles). Part of the implementation
      of #2654.
    * MKVToolNix GUI: multiplexer: when trying to add thumbnails
      for a Blu-ray the GUI will determine the thumbnail's pixel
      size from the thumbnail files if the XML file doesn't
      contain that information. This works for JPEG and PNG files.
      Implements #2674.
    * MKVToolNix GUI: general: line edits & combo boxes will now
      have a "clear text" button appear whenever they're not
      empty. Part of the implementation of #2654.
    * MKVToolNix GUI: update check: the dialog showing the latest
      news & version information states explicitly where the links
      take the user (the MKVToolNix `` file and YouTube
      Bug fixes:
    * mkvmerge: Matroska reader: mkvmerge did not copy the codec's
      private data when reading WavPack from Matroska files. Fixes
    * mkvmerge: MPLS handling: re-added caching when using MPLS
      playlists as input files. Fixes #2666.
    * mkvmerge: MPEG TS reader: when reading an MPLS playlist, the
      calculation of the minimum timestamp to use for shifting all
      output timestamps to zero was wrong. It was wrongfully
      considering timestamps from packets it would not copy due to
      the MPLS's timestamp restrictions. This could lead to the
      first timestamps in the output file being quite large, e.g.
      more than a couple of minutes, causing sync problems when
      multiplexing together with other files. Fixes #2670.
    * MKVToolNix GUI: multiplexer: the automatic switch between
      aspect ratio & display width/height wasn't reflected in the
      configuration generated for `mkvmerge`. The user had to
      change between the two settings manually. Fixes #2660.
    * MKVToolNix GUI: multiplexer: the progress dialog shown when
      scanning a Blu-ray wasn't closed properly in certain
      situations. Fixes #2678.
    * MKVToolNix GUI: general: the configured font was not applied
      to a lot of controls (e.g. the file & track lists or the
      menu entries) on application startup. Instead the user had
      to open & close the preferences in order for the font to be
      applied to all controls. Fixes #2671.
* Sat Nov 09 2019 Luigi Baldoni <>
  - Update to version 40.0.0
    New features and enhancements:
    * mkvmerge: MP4 reader: added support for BMP covert art
    * MKVToolNix GUI: multiplexer: added an option to disable
      deriving the destination file name from the file title.
      Implements #2648.
    * MKVToolNix GUI: multiplexer: the content of the
      "stereoscopy" combo box has been simplified making the box's
      minimum width much smaller, allowing the user to resize the
      GUI's whole window to a much smaller width.
    * MKVToolNix GUI: multiplexer: whenever the user changes the
      "aspect ratio" or "display dimensions" controls, the
      corresponding radio button will be activated automatically.
      Implements #2651.
    * MKVToolNix GUI: Windows: added a setting in the preferences
      to disable the GUI's dark color mode even if Windows's app
      color mode is set to dark. Implements #2646.
    * MKVToolNix GUI: Windows: replaced the dark mode introduced
      in v39 with another dark mode that's less wasteful with
      space between widgets.
    Bug fixes:
    * mkvmerge: MP4 reader: mkvmerge was reading eight bytes too
      many for cover art images. This could cause file
      identification to fail when the cover art was located at the
      end of the MP4 file. Even if it succeeded, this meant too
      much data present in the attachment. Fixes #2650.
    * mkvmerge: MP4 reader: covert art images with unknown image
      types will be skipped instead of treated as JPEG images.
    Build system changes:
    * Qt 5.9.0 or newer is now required for building MKVToolNix
* Tue Nov 05 2019 Luigi Baldoni <>
  - Update to version 39.0.0
    New features and enhancements:
    * mkvmerge: Blu-ray: when reading an MPLS playlist mkvmerge
      will look up and use chapter names from the Blu-ray's
      "track/chapter names" meta data if it exists. Part of the
      implementation of 2486.
    * mkvmerge: MP4 reader: if present, cover art images (the
      `meta.udta.ilist.covr` atom) will be converted into
    * MKVToolNix GUI: multiplexer: when adding a playlist from a
      Blu-ray disc, the disc library meta data will be parsed, and
      the biggest thumbnail, if present, will be added as a new
      attachment with name `cover.jpg` (extension depends on
      thumbnail's extension). Implements #2644.
    * MKVToolNix GUI: multiplexer: when adding a playlist from a
      Blu-ray disc, the title from the disc library meta data will
      be set as the new file title if the disc library meta data
      contains one & no title has been set yet.
    * MKVToolNix GUI: multiplexer: the automatically generated
      destination file name will now be based on the file title if
      one is set at that point. This works in conjunction with the
      title being said from the Blu-ray disc library meta data.
    * MKVToolNix GUI: chapter editor: when reading chapters from
      an MPLS playlist the GUI will look up and use chapter names
      from the Blu-ray's "track/chapter names" meta data if it
      exists. Part of the implementation of 2486.
    * MKVToolNix GUI: Windows: added a dark mode that's enabled
      when Windows 10's dark mode is turned on.
    * translations: added a Bulgarian translation of the programs
      & the man pages by Симеон Цветков (see `AUTHORS`).
    Bug fixes:
    * mkvmerge: attachments without a file name won't be ignored
      anymore. Part of the fix of #2642.
    * MKVToolNix GUI: header editor: attachments with an empty
      name element will be shown as `<unnamed>` as originally
      intended. Part of the fix of #2642.
    * Linux AppImage: the AppImage will no longer change
      directories before running the desired executable allow the
      use of relative file names. Fixes #2632.
    Build system changes:
    * MKVToolNix now requires a C++ compiler that supports the
      following features of the C++17 standard: "`[[maybe_unused]]`
      attribute", "nested namespace definition",
      "structured bindings". For the GNU Compiler Collection (gcc)
      this means v7 or newer; for clang it means v4 or newer.
    * Boost 1.60.0 or newer is now required.
  - Use system nlohmann-json
  - Spec cleanup
* Sun Oct 06 2019 Luigi Baldoni <>
  - Update to version 38.0.0
    New features and enhancements:
    * mkvextract: chapters, tags & cue sheets will now be written
      to standard output if no file name is given, same as if `-`
      is given as the file name.
    * MKVToolNix GUI: job queue: added a new setting in the
      preferences' "job queue & job status" section that, when
      enabled, will cause the GUI to remove all output files
      created by jobs that are either aborted by the user or that
      end in an error. Implements #2614.
    Bug fixes:
    * all programs: macOS: fixed file access if the file name
      (including all path components) contains any Unicode
      character where NFC (Normalization Form Canonical Composed)
      and NFD (Normalization Form Canonical Decomposed) differ,
      e.g. German Umlauts. Fixes #2620.
    * mkvmerge: when splitting by chapters the user can now split
      by chapters coming from one of the appended files, too.
      Fixes #2625.
    * mkvmerge: AAC reader: fixed reading codec parameters
      (channels, sample rate) if a file starts with garbage that
      includes valid-but-bogus AAC headers. Fixes #2622.
    * MKVToolNix GUI: Hebrew was added to the list of often-used
      languages so that it can be selected by default again. Fixes
    * MKVToolNix GUI: when updating the GUI's settings from
      v37.0.0 or older, the GUI checks if the list of often-used
      languages equals the built-in list from v36.0.0. If it does,
      it will be updated to the built-in list changed in v37.0.0.
      Fixes #2611.
    Build system changes:
    * Boost's Operators header library is now required.
* Mon Sep 02 2019 Ismail Dönmez <>
  - Update to version 37.0.0
    New features and enchancements:
    * MKVToolNix GUI: the list of often used languages now contains those from
      Wikipedia's "List of languages by native speakers" by default. Also by
      default only those languages will be shown in the language drop-down boxes.
    * mkvmerge: mkvmerge now allows appending AV1, VP8, VP9, H.264/AVC and
      H.265/HEVC tracks whose pixel dimensions differ. Implements #2582.
    Bug fixes:
    * MKVToolNix GUI: multiplexer: fixed a bug in the "make destination file names
      unique" logic that caused an existing number-in-parenthesis at the end of
      the file base name to be removed in certain situations (e.g. when the first
      added file was named `m (3).mkv` and both `m (3) (1).mkv` and `m (3)
      (2).mkv` existed already, the GUI was suddenly use `m.mkv` instead of `m (3)
    * MKVToolNix GUI: on Windows the GUI is built with a slightly older version of
      the Qt library again (5.12.4). The Qt version used in release v36.0.0,
      v5.13.0, lead to crashes when doing certain things such as selecting
      multiple tracks in the multiplexer. Fixes #2605 and #26008.
    * source code: fixed building with Boost 1.71.0. Fixes #2599.
    * all: fixed the spelling of the H.264 & H.265 codec names.
    * mkvmerge: Blu-ray MPLS handling: mkvmerge will now find corresponding M2TS
      files even if the `clip_codec_identifier` playlist item field is not set to
      `M2TS` in the MPLS file. Fixes #2601.
    * mkvmerge: fixed handling of text files that use both DOS-style and
      Unix-style line endings resulting in problems such as text subtitle files
      not being parsed correctly. Fixes #2594.
* Wed Jun 26 2019 Luigi Baldoni <>
  - Update to version 35.0.0
    New features and enhancements:
    * mkvmerge: JSON identification: the "codec name" track
      property will be output as `codec_name`. The JSON schema has
      been bumped to v12 for this change.
    * MKVToolNix GUI: job queue: added a new type of action to
      execute after job completion: deleting source files for of
      multiplexer jobs. As this is a destructive operation, the
      action is disabled by default. Implements #869 and #2570.
    Bug fixes:
    * mkvmerge: the "codec name" track property wasn't copied from
      Matroska files. Fixes #2566.
    * MKVToolNix GUI: multiplexer: Windows: clearing the
      destination file name will reset the tab name to
      "\<No destination file\>" again. Fixes #2571.
    * MKVToolNix GUI: multiplexer: the file types were not
      re-translated if the UI language was changed. Fixes #2572.

  - Update to version 34.0.0:
    * mkvmerge: bugfix: all subtitle frames are now treated as key
      frames in order to fix wrong data in source files.
    bugfix: AV1: fixed frame timestamp calculation when reading
      bitstreams that lack timing information from IVF files.
    bugfix: Matroska reader: fixed an infinite loop that could
      happen with large video frames and applied timestamp files
      due to too much data being buffered at the wrong time.
* Tue Apr 16 2019 Ferdinand Thiessen <>
  - Update to version 33.1.0:
    * Build with stack protection
  - Update to version 33.0.0:
    * mkvinfo: bugfix: when using the `--size` option, mkvinfo will
    now report the correctly if an element has an unknown size.
    * MKVToolNix GUI: bugfix: info tool: clusters with an unknown
    size will now be read and displayed correctly.
    bugfix: multiplexer: if a destination file names ends with a
    number in parenthesis (e.g. a year such as "(2017)"), that
    number will not be stripped anymore during the process of
    ensuring the destination file name is unique. Only those suffixes
    added automatically in prior attempts to make the file name
    unique will be removed.
  - Update to version 32.0.0:
    * mkvinfo: new feature: when sizes are output the size of the
    element's data portion is output in addition to the element's
    total size.
    * MKVToolNix GUI: new feature: info tool: the element's data
    portion is shown as an extra column.
    new feature: multiplexer: added column "Delay" to the track list
    containing the additional delay to apply during multiplexing.
    bugfix: the portable mode wasn't detected correctly when the
    current working directory the GUI was started from wasn't the
    directory the GUI's executable file was located it.
    bugfix: multiplexer: using button to change the current
    destination directory to one of the recently used ones did not
    update the file name according to the "make file name unique"
    bugfix: multiplexer: the function "set destination file name from
    selected file's name" will now only change the destination file's
    name but not its path.
    * all: fixed handling of Unicode code points > U+FFFF.
  - Update to version 31.0.0:
    * all programs: New Feature: added a new option
    `--abort-on-warnings` that will cause the program to abort after
    it has emitted the first warning, similar to how it aborts after
    the first error.
    * mkvmerge, mkvextract: New Feature: when closing files that were
    opened for writing, cached data will not be flushed to storage
    automatically anymore. A new option was added to both programs
    (`--flush-on-close`) that re-enables flushing for people who are
    affected by data loss.
    The reason is that automatic flushing causes long delays in
    processing queues when the output by mkvmerge/mkvextract isn't
    the final product but just an intermediate result to be
    processed further.
    Bugfix: AVI reader: using DV type 1 AVIs will now result in an
    unsupported file type being reported instead of crashing mkvmerge
    Bugfix: HEVC: the height of interlaced streams will now be set
    correctly to the height of the full frame instead of the height of
    a single interlaced field.
    Bugfix: MP4 reader: edit lists consisting solely of elements that
    mkvmerge doesn't support (such as dwells) are simply ignored.
    Before no data was read for such tracks at all.
    Bugfix: text subtitles: entries with an explicit duration of 0ms
    will now be handled correctly: the 0ms duration will be stored
    in Matroska instead of the difference between the current and
    the following entry.
    * MKVToolNix GUI: New Feature: multiplexer: the dialog previewing
    different character sets for text subtitles will now keep the
    position of the displayed text when switching between character
    Bugfix: multiplexer, chapter editor: fixed drag & drop handling
    with Qt 5.12.0 and newer.
    Bugfix: multiplexer: the GUI did not clean up temporary files
    created when running `mkvmerge`.
* Tue Mar 19 2019 plater <>
  - Fix Factory build by changing rubygem-rake build requirement to
    rubygem(rake) and adding libboost_system build dependency again,
    fixes boo#1129626
* Mon Jan 14 2019 Martin Pluskal <>
  - Drop libboost_system dependency as it is not needed
* Sat Jan 12 2019 Ferdinand Thiessen <>
  - Update to version 30.1.0:
    * MKVToolNix GUI: bugfix: chapter editor: when opening a
    Matroska/WebM file that doesn't contain chapters and later
    saving chapters back to them, the editor was truncating the file
    down to a couple of KB in size.
  - Update to version 30.0.0:
    * MKVToolNix GUI: New Feature: multiplexer: a new button was
    added next to the "destination file" controls. Clicking it
    shows a menu with the ten most recently used output
    directories. Selecting one of them will change the destination
    file to the selected directory keeping the file name.
    New Feature: The ten most recently used values for the "relative
    output directory" and "fixed output directory" settings are now
    saved. The corresponding settings have been changed into combo
    boxes allowing quick access to those recent values.
    New Feature: The predefined split sizes and durations can now be
    customized in the preferences.
    New Feature: chapter editor: added an option in the "Chapter
    editor" menu for appending chapters from an existing file to the
    currently open editor tab.
    New Feature: Added an action in the context menu for copying the
    selected entry and all of its children to another open editor tab.
    Bugfix: removing a file added as an "additional part" will no
    longer cause a crash.
    * mkvextract: New Feature: WAV extractor: mkvextract will now
    write W64 files instead of WAV files if the file name extension
    is `.w64` or if the final file size is bigger than 4 GB, the
    file size limit for WAV files.
    * mkvmerge: Bugfix: all files opened for writing will now be
    flushed once before they're closed. This ensures the operating
    system actually writes all cached data to disk preventing data
    loss in certain situations such as power outages or buggy drivers
    in combination with suspending the computer.
    Bugfix: AAC: under certain conditions 8 channel audio files were
    taken for 7 channel ones.
  - Update to version 29.0.0:
    * MKVToolNix GUI: New Feature: added an option in the preferences
    for disabling automatic scaling for high DPI displays.
    New Feature: The GUI will now prevent the system from going to
    sleep while the job queue is running.
    * mkvmerge: Bugfix: chapter generation: the start timestamps of
    chapters generated in intervals was wrong for files whose
    smallest video timestamp was bigger than 0.
    Bugfix: MP4 reader: fixed handling of atoms whose size exceeds the
    parent atom's size.
    Bugfix: the chapter name template will now also be used when
    reading Ogg-style chapter files with empty chapter names.
    * mkvextract: Bugfix: AAC: mkvextract will now write the program
    config element (PCE) before the first AAC raw data packet if the
    PCE is present in the `AudioSpecificConfig` structure in the
    `Codec Private` Matroska element. The  PCE carries vital
    information about the number of channels and is required in
    certain cases.
    * mkvpropedit, MKVToolNix GUI's header editor: Bugfix: in
    situations when a one-byte space must be covered by a new EBML
    void element the following element must be moved up instead.
    If that moved element is a cluster, the corresponding cue
    entries will now be updated to reflect the cluster's new
* Tue Oct 30 2018 Ferdinand Thiessen <>
  - Update to version 28.2.0
    * mkvmerge, mkvinfo, mkvextract, mkvpropedit, MKVToolNix GUI's info
    tool & chapter editor: fixed a case of memory being accessed after
    it had been freed earlier. This can be triggered by specially
    crafted Matroska files and lead to arbitrary code execution. The
    vulnerability was reported as Cisco TALOS 2018-0694 on 2018-10-25
    (CVE-2018-4022). Fixes boo#1113709.
  - Update to version 28.1.0
    * mkvmerge: bugfix: AV1 parser: fixed an error in the sequence
    header parser if neither the `reduced_still_picture_header` nor
    the `frame_id_numbers_present_flag` is set.
    bugfix: AV1 parser: when creating the `av1C` structure for the
    Codec Private element the sequence header OBU wasn't copied
    completely: its common data (type field & OBU size among others)
    was missing.
    bugfix: Matroska reader, AV1: mkvmerge will try to re-create the
    `av1C` data stored in Codec Private when reading AV1 from
    Matroska or WebM files created by mkvmerge v28.0.0.
    * MKVToolNix GUI: bugfix info tool: the tool will no longer stop
    scanning elements when an EBML Void element is found after the
    first Cluster element.
  - Update to version 28.0.0
    * mkvmerge: New feature: AV1 parser: updated the code for the
    finalized AV1 bitstream specification.
    New feature: AV1 packetizer: updated the code for the finalized
    AV1-in-Matroska & WebM mapping specification.
    New feature: AV1 support: the `--engage enable_av1` option has
    been removed again.
    New feature: MP4 reader: added support for AV1.
    New feature: DTS: implemented dialog normalization gain removal
    for extension substreams.
    New feature: VP9: mkvmerge will now create codec private data
    according to the VP9 codec mapping described in the WebM
    bugfix: JSON identification: fixed a bug when removing invalid
    UTF-8 data from strings before they're output as JSON.
    bugfix: MP4/QuickTime reader: fixed handling of PCM audio with
    FourCC `in24`.
    bugfix: MPEG transport stream reader, teletext subtitles: the
    decision whether or not to keep frames around in order to
    potentially merge them with the following frame is made sooner.
    That avoids problems if there are large gaps between teletext
    subtitle frames which could lead to frames being interleaved
    too late.
    * mkvmerge, mkvextract: New feature: simple text subtitles:
    added a workaround for simple text subtitle tracks that don't
    contain a duration.
    * mkvextract: New feature: added support for extracting AV1 to IVF.
    New feature: IVF extractor (AV1, VP8, VP9): precise values will
    be used for the frame rate numerator & denominator header fields
    for certain well-known values of the track's default duration.
    * MKVToolNix GUI: New feature: automatic scaling for high DPI
    displays is activated if the GUI is compiled with Qt ≥ 5.6.0.
    New feature: added a menu item ("Help" → "System information") for
    displaying information about the system MKVToolNix is running on
    in order to make debugging easier.
    New feature: multiplexer, header editor: the user can enter a list
    of predefined track names in the preferences. She can later select
    from them in "track name" combo box.
    * mkvextract: bugfix: IVF extractor (AV1, VP8, VP8): the frame rate
    header fields weren't clamped to 16 bits properly causing wrong
    frame rates to be written in certain situations.
    * mkvpropedit, MKVToolNix GUI's header editor: bugfix: fixed file
    corruption when a one-byte space must be covered with a new EBML
    void element but all surrounding elements have a "size length"
    field that's eight bytes long already.
* Thu Oct 18 2018 Ferdinand Thiessen <>
  - Update to version 27.0.0:
    * mkvmerge: New feature: chapters: the timestamps of chapters
    read from containers or from chapter files can be adjusted
    (multiplication and addition) with the new
    `--chapter-sync` option or using the special track ID `-2`
    for the existing `--sync` option.
    Bugfix: AC-3: dialog normalization gain removal was corrupting
    E-AC-3 frames irreversibly by writing checksums in places where
    they didn't belong. Additionally only the first E-AC-3 frame in
    a Matroska was processed but not additional dependent frames in
    the same block.
    * MKVToolNix GUI: New feature: multiplexer: adjusted & added
    controls for mkvmerge's new feature of being able to adjust
    chapter timestamps.
    New feature: multiplexer: the GUI can now ask for confirmation
    when the user is about to create a file that won't contain
    audio tracks. It does this by default if at least one source
    file contains an audio track.
    Bugfix: fixed a leak of Windows font resources leading to a
    general slowdown and subsequent crash.
  - Update to version 26.0.0:
    * mkvmerge: New feature: chapter generation: if the name template
    given by `--generate-chapters-name-template` is empty, no names
    will be generated for the chapter atoms.
    New feature: chapters: chapter names generated from MPLS files
    will now use the name template if one is set via
    New feature: mkvmerge will no longer abort with an error message
    if no audio, video and subtitle tracks should be multiplexed.
    This allows copying of chapters from non-chapter source files.
    Bugfix: Matroska reader: fixed wrong timestamps when appending
    Matroska files where the second Matroska file's first timestamp
    is bigger than 0.
    Bugfix: MP4 reader: fixed division by zero errors during file
    identification if the timescale is 0 in the `MVHD` atom.
    Bugfix: Windows Television DVR files are now recognized as an
    unsupported file type. This prevents mis-detection as MPEG-2
    with an accompanying flood of error messages.
    * MKVToolNix GUI: New feature: the font size in the tool
    selector on the left will scale with the font size the
    user selects in the preferences.
    New feature: the GUI will no longer automatically resize the
    columns in tree and list views to match the content size.
    Instead it remembers and restores the widths set by the user.
    New feature: multiplexer: the chapter name template will now be
    set automatically to the name template in the preferences'
    "chapter editor" section. Additionally the option
    `--generate-chapters-name-template …` will be passed to
    mkvmerge in situations when mkvmerge will generate chapters.
    New feature: chapter editor: if the chapter name template is empty,
    chapters will be generated without names.
    New feature: chapter editor: added an option to remove all chapter
    names to the "additional modifications" dialog.
    Bugfix: info tool: under certain circumstances "cues" were shown at
    the wrong level (inside the previous master element instead of on
    lvel 1).
    Bugfix: job queue: fixed invalid memory handling and consequent
    crashes when using the "edit in corresponding tool & remove from
    job queue" option if one of the files in that job contained
    attached files.
* Wed Aug 08 2018
  - Update to 25.0.0:
    * mkvextract: New feature: VobSub extraction: empty SPU packets
      will now be dropped during extraction as other tools such as
      MP4Box cannot handle them correctly.
    Bugfix: fixed a crash when mkvextract with a non-Matroska file as
      the source file.
    * MKVToolNix GUI: New feature:: multiplexer: added options to only
      enable tracks of certain types by default.
    New feature: multiplexer: added an option to enable dialog
      normalization gain removal by default for all audio tracks for
      which the operation is supported.
    New feature: multiplexer: when deriving track languages from the
      file names is active and the file name contains the usual
      season/episode pattern, then only the part after the
      season/episode pattern will be used for detecting the language.
    New feature: multiplexer: the regular expression used for deriving
      track languages from the file names can now be customized in
      the preferences.
    New feature: multiplexer: the user can now customize the list of
      track languages the GUI recognizes in file names. This list
      defaults to a handful of common languages instead of the full
      list of supported languages.
    Bugfix: multiplexer: when scanning playlists, all playlists were
      offered for selection regardless of the value of the "minimum
      playlist duration" setting.
    Bugfix: multiplexer: deriving track languages from file names:
      the regular sub-expressions for ISO 639-1 codes could match
      on empty strings, too, causing matches in wrong places and hence
      no language being recognized in certain situations.
    Bugfix: header editor: fixed a crash when saving the file fails
      (e.g. because it isn't writable).
    Bugfix: header editor: the editor was wrongfully claiming that
      mandatory elements with default values cannot be removed in
      the "status" text.
    Bugfix: preferences: on macOS & Linux the setting "enable copying
      tracks by their type" wasn't restored on program start.
    Bugfix: the central area is now scrollable, allowing the GUI to be
      resized to almost arbitrary sizes.
    Bugfix: multiplexer: the "copy file title to destination file name"
      functionality will now replace everything in the destination file
      name up to the last period instead of only up to the first period.
    * mkvmerge: New feature: SRT/ASS/SSA text subtitles: for files for
      which no encoding has been specified, mkvmerge will try UTF-8
      first before falling back to the system's default encoding.
    New feature: SRT/ASS/SSA/WebVTT text subtitles: a warning is now
      emitted if invalid 8-bit characters are encountered outside valid
      multi-byte UTF-8 sequences.
    New Feature: Matroska & MPEG transport stream readers: the encoding
      of text subtitles read from Matroska files can now be changed
      with the '--sub-charset' parameter.
    New feature: MP4 reader: improved the detection of edit lists
      consisting of two identical entries, each spanning the file's
      duration as given in the movie header atom. The second entry is
      ignored in such cases.
    New feature: JSON identification: the "display unit" video track
      property is now reported as `display_unit`. The JSON schema has
      been bumped to v11 for this change.
    New feature: AVC/h.264: empty NALUs will now be removed.
    New feature: input: format detection uses file-extension to improve
      performance and to give preference when several formats match.
    New feature: AV1: added support for reading AV1 video from
      Open Bitstream Unit files.
    New feature: AV1: adjusted the code for the AV1 bitstream format
      changes made up to 2018-05-02 (git revision d14e878).
    New feature: MP4 reader: if a track has an edit list with two
      identical entries, each spanning the file's duration as given in
      the movie header atom, then the second entry will now be ignored.
      Improves the handling of files with bogus data.
    Bugfix: AVC/h.264 and HEVC: fixed file identification failing
      for certain elementary streams due to internal buffers not
      being cleared properly.
    Bugfix: MLP code: fixed various issues preventing MLP from being
      parsed correctly.
    Bugfix: TrueHD/MLP packetizer; dialog volume normalization removal
      isn't attempted if the track is an MLP track as the operation is
      only supported for TrueHD, not MLP.
    Bugfix: MPEG TS reader: when reading MPLS mkvmerge will now
      compare the MPLS's start and end timestamps against the transport
      stream's PTS instead of its DTS. Otherwise the first key frame of
      a video track might be dropped if it isn't the first in
      presentation order.
    Bugfix: JSON identification: mkvmerge will ensure that all strings
      passed to the JSON output modules are valid UTF-8 encoded strings
      by replacing invalid bytes with placeholder characters. This avoids
      the JSON library throwing an exception and mkvmerge
      aborting on such data.
    Bugfix: audio packetizers: mkvmerge will now keep discard
      padding values if they're present for packets read
      from Matroska files.
    Bugfix:  Ogg Opus reader: packet timestamps aren't calculated by
      summing up the duration of all packets starting with
      timestamp 0 anymore. Instead the algorithm is based on the Ogg page's
      granule position and which packet number is currently timestamped
      (special handling for the first and last packets in the stream).
    Bugfix: E-AC-3 parser: fixed determining the number of channels for
      streams that contain an AC-3 core with dependent E-AC-3 frames.
    Bugfix:  Matroska reader: fixed mkvmerge buffering the whole file if a
      video track is multiplexed that consists of only one or a few frames.
    Bugfix: the "display unit" video track property will now be kept if
      it is set in the source file.
    Bugfix:  MP3 packetizer: removed a memory leak growing linearly with the
      track's size.
    Bugfix: VobSub packetizer: whenever a VobSub packet doesn't contain a
      duration on the container level, mkvmerge will now set it from
      the duration in the SPU packets. Before it was accidentally setting
      the SPU-level duration to 0 instead.
    Bugfix:  track statistics tags: if writing the `Date` element is
      deactivated via `--no-date`, the `_STATISTICS_WRITING_DATE_UTC`
      isn't written either anymore.
    Bugfix: removed several small, constant-size memory leaks.
* Mon Apr 09 2018
  - Update to 22.0.0:
    * mkvmerge: New feature: AC-3, DTS, TrueHD: added an option for
      removing/minimizing the dialog normalization gain for all
      supported types of the mentioned codecs.
    New feature: AV1: added support for reading AV1 video from IVF,
      WebM and Matroska files.
    New feature: FLAC: mkvmerge can now ignore ID3 tags in FLAC
      files which would otherwise prevent mkvmerge from detecting the
      file type.
    Bugfix: MP4 reader: fixed reading the ESDS audio header atom if
      it is located inside a "wave" atom inside the "stsd" atom.
    Bugfix: MP4 reader: AAC audio tracks signalling eight channels
      in the track headers but only seven in the codec-specific
      configuration will be treated as having eight channels.
    Bugfix: MPEG TS reader: fixed wrong handling of the continuity
      counter for TS packets that signal that TS payload is present
      but where the adaptation field spans the whole TS packet.
    Bugfix: the 'document type version' and 'document type read version'
      header fields are now set depending on which elements are
      actually written, not on which features are active.
    Bugfix: the 'document type version' header field is now set
      to 4 correctly if any of the version 4 Matroska elements
      is written.
    * mkvinfo: New Feature: the size and positions of frames
      within "SimpleBlock" and "BlockGroup" elements are now shown
      the same way they're  shown for other elements.
    Bugfix: summary mode: the file positions reported for frames in
      `BlockGroup` elements did not take the bytes used for
      information such as timestamp, track number flags or lace sizes
      into account. They were therefore too low.
    * mkvpropedit, MKVToolNix GUI header editor: the
      'document type version' and 'document type read version' header
      fields are now updated if elements written by the changes require
      higher version numbers.
    Bugfix: mandatory elements can now be deleted if there's a default
      value for them in the specifications.
    * MKVToolNix GUI: multiplexer: added options for deriving the
      track languages from the file name by searching for
      ISO 639-1/639-2 language codes or language names enclosed in
      non-word, non-space characters.
    Bugfix: info tool: implemented reading all elements in the file
      after the first cluster. Only top-level elements are shown;
      child elements are only loaded on demand.
    Bugfix: info tool: added a context menu with the option to show a
      hex dump of the element with the bytes making up the EBML ID and
      the size portion highlighted in different colors.
      In-depth highlighting is done for the data in `SimpleBlock`
      and `Block` elements.
    Bugfix: chapter editor: added an option to remove all end
      timestamps to the "additional modifications" dialog.
  - Update to 21.0.0:
    * mkvinfo: the GUI portion has been removed. mkvinfo is now a pure
      command-line program again.
    * mkvmerge: New feature: track statistics tags: the `TagDefault`
      element will not be written anymore as it was always set to the
      default value `1` anyway.
    New feature: JSON files can now contain C++-style line comments
      outside of strings. Such comments, even though not part of the
      official JSON specifications, are now ignored when reading JSON
    Bugfix: Appending files with additional parts at the same time
      was broken if more than one additional part was appended.
    Bugfix: FLV reader: a single invalid AAC frame was written for
      AAC audio tracks with codec initialization data longer than five
    Bugfix: FLV reader: timestamps will be normalized down to 0.
    Bugfix: MP4 reader: if an AAC track doesn't contain an
      AAC-specific decoder configuration in the ESDS portion,
      then a default decoder configuration will be generated based on
      the track's header data instead of skipping the track.
    Bugfix: MP4 reader: fixed reading HEVC/h.265 video tracks if
      they're stored as Annex B byte streams inside MP4.
    Bugfix: Ogg Opus reader: mkvmerge will now emit a warning
      instead of aborting when it encounters an Ogg Opus page with
      no data in the packet.
    Bugfix: Matroska parser: fixed a segmentation fault that
      occurred whenever the first level 1 element after resyncing
      after an error in the file structure isn't a cluster.
    Bugfix: fixed a crash during file type detection for
      attachments if MKVToolNix is installed in a path with
      non-ASCII characters (e.g. German Umlauts).
    * MKVToolNix GUI: New Feature: chapter editor: opening a
      Matroska file without chapters in it will now open the file
      in an empty chapter editor instead of showing an error message.
    New Feature: an "info" tool has been added, replacing the
      functionality of mkvinfo's GUI. The functionality is not on
      par yet but will be for release v22.
    Bugfix: MKVToolNix GUI: Bugfix: multiplexer: the subtitle
      character set can now be set for appended subtitle files, too.
    Bugfix: MKVToolNix GUI: multiplexer: when appending, all tracks
      appended to disabled tracks will start out disabled, too.
    * mkvinfo: the `--hex-positions` parameter did nothing in summary mode.
    Bugfix: mkvinfo: Windows: line endings will be written as `\r\n`
      again instead of just `\n`.
    * mkvpropedit: Bugfix: adding track statistics tags: for tracks
      with content encoding (compression) mkvpropedit is now
      accounting the uncompressed number of bytes, not the encoded
      (compressed) number of bytes.
* Sun Jan 21 2018
  - Update to 20.0.0:
    * Feature removal: several deprecated features have been removed:
    mkvmerge: the deprecated options `--identify-verbose`,
      `--identify-for-gui`, `--identify-for-mmg` and
      `--identification-format verbose-text`
    all command line tools: support for the deprecated, old,
      proprietary format used for option files
    all command line tools: support for passing command line
      options via the deprecated environment variables
    * mkvmerge: AVC/h.264 packetizer (framed): access unit delimiter
      NALUs will now be removed.
    bugfix: AVC/h.264 parser: when fixing the bitstream timing
      information mkvmerge will now use exact representations of
      the desired field duration if possible.
    bugfix: AVC/h.264 parser: mkvmerge no longer assumes that
      encountering sequence parameter set or picture parameter set
      NALUs signal the start of a new frame.
    bugfix: AVC/h.264 packetizer (framed): when mkvmerge is told
      to fix the bitstream timing information, it will now update
      all SPS NALUs, not just the ones in the AVCC.
    bugfix: MPEG TS reader: TS packet payloads will only be
      treated as PES packets if the payload actually starts with
      a PES start code. The prior behavior led to wrong timestamps
      and potentially broken frame data.
    bugfix: MPEG TS reader: mkvmerge will now drop incomplete PES
      packets as soon as an error is detected in the transport
      stream instead of passing the incomplete frame to the
      packetizer. An error is assumed either if the
      `transport_error_indicator` flag is set or if the value of
      the `continuity_counter` header field doesn't match the
      expected value.
    bugfix: Opus: when re-muxing Opus from Matroska mkvmerge will
      now write "block duration" elements for all block groups
      where a "discard padding" is set, too.
    bugfix: SRT reader: mkvmerge can now handle SRT files with
      timestamps without decimal places.
    bugfix: read buffer I/O class: the class could get out of sync
      regarding the file position of the underlying file I/O class
      causing wrong data to be returned on subsequent read
      operations. One result was that trying to identifying MPLS
      files that refer to very short M2TS files caused mkvmerge
      to segfault.
    bugfix: multiplexer core: if there's a gap in audio timestamps,
      a new block group/lace will be started for the first frame
      after each gap. Before the fix the frame after the gap was
      often stored in the previous block group causing the gap to
      be in the wrong place: at the end of that block group.
    * mkvextract: bugfix: AVC/h.264: if two consecutive IDR frames
      with the same `idr_pic_id` parameter and no access unit
      delimiters are found between them, mkvextract will insert an
      access unit delimiter in order to signal the start of a new
      access unit.
    * MKVToolNix GUI: bugfix: update check dialog: Markdown links will
      now be converted to clickable links.
* Mon Dec 25 2017
  - Update to new upstream release 19.0.0
    * mkvmerge: splitting by duration, by timestamps or by
      timestamp-based parts: mkvmerge will now consider the first
      key frame within 1ms of the requested value to be eligible
      for splitting.
    * mkvmerge: fixed reading text files encoded in UTF-16 order
      UTF-32 that have different forms of line endings (new lines,
      carriage returns or a mix of both).
    * MKVToolNix GUI: multiplexer: once a "subtitle/chapter
      character set" was set for a track it couldn't be changed
      back to the empty entry (= auto-detection) anymore.
* Tue Dec 12 2017
  -Update to 18.0.0:
    * mkvmerge: bugfix: AAC ADTS parser: fixed interpretation of the
      `channel_configuration` header element for ADTS files that do
      not contain a program configuration element: value 7 means
      7.1 channels.
    bugfix: Matroska identification: the `date_local` and
      `date_utc` attributes will only be output if the identified
      Matroska file actually contains the "date" header field.
    bugfix: WebVTT: mkvmerge did not recognize timestamp lines if
      the hours components were absent.
    enhancement: AVC & HEVC ES parsers: performance improvements
      by copying much less memory around.
    enhancement: tags: reintroduced a workaround for non-compliant
      files with tags that do not contain the mandatory `SimpleTag`
      element. This workaround was removed during code refactoring
      in release v15.0.0.
    * mkvpropedit: bugfix: GUI's header editor: the `date` header
      field won't be added automatically anymore whenever the
      segment info section is edited and the `date` element is
      either deleted or not present in the first place.
    * GUI: multiplexer: the "AAC is SBR/HE-AAC/AAC+" checkbox in
      the "audio properties" section will be disabled if the
      functionality is not implemented for the selected track's
      codec & container.
    enhancement: multiplexer: the "reduce to core" checkbox in
      the "audio properties" section will be disabled if the
      functionality is not implemented for the selected track's
* Wed Nov 08 2017
  - Update to 17.0.0:
    * The word "timecode" has been changed to "timestamp" everywhere.
    This affects program output (including mkvinfo's), GUI controls,
    command line parameters (e.g. `mkvmerge --timestamp-scale …`) and
    file formats.
    All programs remain backwards compatible insofar as they still
    accept "timecode" in all those places.
    * mkvextract's command line interface has been changed to allow
    extraction of multiple items at the same time.
    * mkvmerge: New feature: AC-3: during identification regular AC-3
      and E-AC-3 tracks will now be identified differently for most
      container formats (exception: AVI, Real Media, Ogg/OGM).
      The codec will be reported as `AC-3` for regular AC-3 and as
      `E-AC-3` for E-AC-3 tracks instead of the combined `AC-3/E-AC-3`.
    bugfix: AAC ADTS parser: mkvmerge will now parse the
      `program_config_element` if it is located at the start of an AAC
      frame in order to determine the actual number of channels.
      This overrides invalid channel configurations in the ADTS headers.
    bugfix: fixed AC-3 being misdetected as encrypted MPEG program
      streams under certain conditions.
    bugfix: Dirac: under certain conditions (e.g. only muxing a single
      Dirac track without any other tracks) mkvmerge was always setting
      the pixel width & height to 123. The frame rate was wrong, too.
    bugfix: E-AC-3 in Matroska: if AC-3 cores and their corresponding
      E-AC-3 extension are located in two different Matroska blocks,
      then mkvmerge will now re-assemble them into a single block and
      only use the first block's timestamp.
    bugfix: SRT reader: fixed calculating the duration of entries
      starting with at a negative timestamp.
    bugfix: VC-1: under certain conditions (e.g. only muxing a single
      VC-1 track without any other tracks) mkvmerge was always setting
      the pixel width & height to 123. The frame rate was wrong, too.
    bugfix: command line options: an error message will be output if
      the single-value-form of the `--sync` option is used and it
      isn't a number (e.g. `--sync 0:asd`).
    * mkvpropedit, GUI's header editor: bugfix: both programs will now
      show proper error messages instead of crashing when certain
      kinds of data corruption is found when reading a file.
  - Update to 16.0.0:
    * mkvmerge: New feature MP4 reader: added support for Vorbis.
    bugfix: AAC reader: mkvmerge will now emit an error message for
      AAC files whose header fields imply a sampling frequency
      or number of channels of 0.
    bugfix: AVC/h.264 ES parser: fixed the calculation of reference
      information for P and B frames. This also fixes some P frames
      being marked as B frames and vice versa.
    bugfix: AVC/h.264 ES parser: only non-key frames that have the
      NALU header field `nal_ref_idc` set to 0 will be marked as
      "discardable" in `SimpleBlock` elements. Other half of the
      fix for #2047.
    bugfix: HEVC/h.265: the generation of the HEVCC structure
      stored in `CodecPrivate` was wrong in two places:
      1. the position of the number of sub-layers was swapped with
      reserved bits and 2. the VPS/SPS/PPS/SEI lists did not start
      with a reserved 1 bit.
    bugfix: output: the `doc type version` will be set at least
      to 2 if certain elements are written (`CodecState`,
      `CueCodecState`, `FlagInterlaced`).
    bugfix: output: the track header attributes `MinCache` and
      `MaxCache` will not be written anymore.
    bugfix: Matroska reader: the "key" and "discardable" flags of
      SimpleBlock elements will be kept as they are.
    bugfix: Matroska reader: if present in the file,
      the "white colour coordinate x" track header attribute was
      written to both "white colour coordinate x" and
      "white colour coordinate y" in the output file.
    bugfix: Opus output: mkvmerge will now put all frames with
      discard padding into their own block group.
    * MKVToolNix GUI: Bugfix: header editor: removed the check for
      external modification when saving the file.
    bugfix: job queue: fixed calculation of total progress when
      automatic removal of completed is enabled.
* Thu Aug 31 2017
  - Update to 15.0.0:
    * Requires libebml >= 1.3.5
    * Dropped disable-update-check.patch (upstream now provides
      configure option for disabling the update check).
    * mkvmerge, mkvpropedit, GUI's header and chapter editors: the
      programs will no longer add most missing Matroska elements that
      are mandatory but have a default value in the Matroska
      specification (e.g. the `TagLanguage` element with a value of
      `und` if it isn't present in its `SimpleTag` parent).
    * mkvmerge: the option `--colour-matrix` has been renamed to
      `--colour-matrix-coefficients` in order to match the
      specification more closely. The old option name will
      continue to be recognized as well.
    * all: bugfix: selecting the program's language (e.g. via the
      `--ui-language`command-line option or via the GUI's
      preferences) did not work on Linux & Unix if the `LANGUAGE`
      environment variable was set and didn't include the desired
    * MKVToolNix GUI: new feature: multiplex tool: added a new entry
      to the "source files" context menu labeled "Set destination
      file name from selected file's name". It will force the GUI
      to consider the selected file to be the reference for
      automatically setting the file name, no matter which file was
      originally added as the first file. It will also force setting
      the destination file name once if automatic destination file
      name generation is turned off in the preferences.
    new feature: multiplex tool: added an option in the preferences
      on "Multiplexer" → "Output" labeled "Only use the first source
      file that contains a video track". If enabled, only source
      files containing video tracks will be used for setting the
      destination file name. Other files that are added are ignore.
    new feature: header editor: added support for editing the video
      colour attributes.
    new feature: header editor: added support for the "video
      projection" track header attributes.
    new feature: job queue: selected jobs can now be move up and
      down by pressing the `Ctrl+Up` and `Ctrl+Down` keys.
      Additionally, push buttons to move them up & down are shown
      if the corresponding option is enabled in the preferences.
    bugfix: removed the keyboard shortcuts for switching between
      the different tools (e.g. `Ctrl+Alt+1` for the multiplexer).
      They overlapped with basic functionality on keyboards that
      use an `AltGr` key, e.g. German ones, where `AltGr+7` emits
      `{`. As `AltGr+key` is implemented as `Ctrl+Alt+key` under the
      hood, this means that `AltGr+7` is really `Ctrl+Alt+7` which
      the GUI now took to mean "switch to the job queue" instead of
      "insert `{`".
    bugfix: header editor: after saving the file the GUI wasn't
      updating its internal file modification timestamp. That lead
      to the GUI wrongfully claiming that the file had been
      modified externally when the user wanted to save the file
      once more, requiring a reload of the file losing all
      modifications made since saving the first time.
    * mkvmerge: new feature: added support for the
      "video projection" track header attributes.
    bugfix: DTS handling: some source files provide timestamps for
      audio tracks only once every `n` audio frames.
      In such situations mkvmerge was buffering too much data
      resulting in a single gap in the timestamps of one frame
      duration after frame number `n - 1` (the second audio
      timestamp read from the source file was used one output
      frame too early).
    * mkvinfo: new feature: added support for the
      "video projection" track header attributes.
    bugfix: fixed a null pointer dereference if an `EbmlBinary`
      element's data pointer is a null pointer.
    * mkvpropedit: new feature: added support for editing the
      video colour attributes.
    new feature: added support for the "video projection"
      track header attributes.
* Fri Aug 25 2017
  - Split boost-devel BuildRequires for Tumbleweed
  - Update to version 14.0.0
    * mkvmerge, mkvpropedit, MKVToolNix GUI (chapter editor):
    new feature: added support for chapters in WebM files that is
      spec-compliant by removing all tag elements not supported
      by the WebM spec.
    * translations: added a Romanian translation of the programs.
    * mkvmerge: bugfix: AVC/h.264 and HEVC/h.265 parser: fixed wrong
      frame order & timestamp calculation in certain situations when
      SPS (sequence parameter sets) or PPS (picture parameter sets)
      change mid-stream.
    bugfix: MPEG-1/-2 video: the "remove stuffing bytes" feature
      introduced in v5.8.0 was broken. In a lot of situations it
      did not detect the end of a slice correctly and removed 0 bytes
      that were actually part of the slice structure. Often there
      were no visual problems as decoders were able to ignore such
      errors, but in other cases there are visual artifacts upon
      decoding. As detecting the slice end properly requires parsing
      the whole slice structure, this feature has been removed again.
    bugfix: MPEG PS reader: fixed mkvmerge trying to handle an "end"
      code the same way as a "program stream map" code.
    bugfix: MPEG TS reader: mkvmerge won't emit warnings if the
      system's `iconv` library doesn't support the ISO 6937
      character set.
    bugfix: when appending fails the error message details (e.g.
      "the number of channels differs: 1 and 2") were often not output.
    new feature: AAC: implemented support for AAC with 960 samples per
    new feature: identification: if the encoding/character set of a
      text subtitle track is known (e.g. because a byte order mark is
      present in the file), then it will be output during
      identification as the `encoding` property.
    new feature: WAV reader: added support for Wave64 files.
    * MKVToolNix GUI: bugfix: multiplex tool: implemented a workaround
      for a crash that could occur during drag & drop if at least one
      of the columns is hidden.
    bugifx: multiplex tool: appended tracks can no longer be enabled
      (selected for multiplexing) if the track they're going to be
      appended to is not enabled.
    bugifx: multiplex tool: if the GUI is set to ensure unique output
      file names, it will now verify that right before starting to
      multiplex/adding the job to the queue, too.
    bugifx: fixed the total progress reverting to 0% instead of
      staying at 100% when all jobs have finished. This was introduced
      by the attempt at fixing the computation of the value of total
      progress bar for multiple jobs running.
    new feature: multiplexer: if the encoding/character set of a
      subtitle track cannot be changed, the GUI will deactivate the
      "subtitle character set" drop-down box and ignore changes to it
      when multiple tracks are selected. Additionally, if the track's
      encoding is known and cannot be changed (e.g. due to a
      byte order mark in the file), that encoding will be selected in
      the drop-down box automatically. Both changes signal to the user
      that she doesn't have to take care of the encoding herself.
    new feature: chapter editor: added a function to the "additional
      modifications" dialog for calculating and setting the end
    new feature: changed the shortcuts for switching between the
      various tools from `Alt+number` (e.g. `Alt+1` for the multiplexer
      tool) to `Ctrl+Alt+number` in order to avoid clashing with
      Windows' input method for arbitrary characters (pressing and
      holding `Alt` and typing the codepoint on the number pad).
    new feature: added a "Window" menu and entries with shortcuts for
      selecting the next (`Ctrl+F6`) respectively previous tab
      (`Ctrl+Shift+F6`) in the current tool.
* Thu Jul 13 2017
  - Update to version 13.0.0
    * mkvmerge: new feature: MPEG TS reader: information about
      multiple programs will be output as container properties during
      verbose/JSON identification.
    bugfix: MP4 reader: MPEG-1/2 video read from MP4 files was written
      with an invalid codec ID (e.g. `V_MPEG7`) in certain cases.
    bugfix: MPEG PS reader: made the file type detection less strict
      so that garbage at the start of the file doesn't prevent detection.
    bugfix: MPEG PS reader: (E-)AC-3 tracks were not detected if the very
      first packet for that track didn't contain a full (E-)AC-3 frame.
    bugfix: MPEG TS reader: fixed mkvmerge not detecting all tracks in
      MPEG transport streams containing multiple programs.
    bugfix: MPEG TS reader: fixed track content being broken for some
      tracks read from MPEG transport streams containing multiple programs.
    bugfix: JSON identification: the `stream_id` and `sub_stream_id`
      track properties were output as hexadecimal strings instead
      of unsigned integers. As the `ts_pid` track property was only
      used for MPEG transport streams, its value is now output as
      `stream_id` instead, and the `ts_pid` property has been removed.
      The JSON schema version has been bumped to 8 due to this change.
    bugfix: fixed a crash when appending video tracks where one track
      has a CodecPrivate member and the other one doesn't.
    bugfix: track statistics tags: the `NUMBER_OF_BYTES` tag
      is supposed to contain the number of bytes in a track before any
      of the content encoding schemes such as lossless compression
      is applied; however, mkvmerge was wrongfully using the number of
      bytes after the schemes had been applied.
    bugfix: CLPI & MPLS parsers: MPLS and CLPI files with version
      number `0300` as used on Ultra HD Blu-ray Discs are
      now accepted as well.
    * MKVToolNix GUI: new feature: multiplex tool: added a column
      "program" to the tracks list. Certain container types such
      as MPEG transport streams can contain multiple programs.
      The new column will contain the service name (think TV station
      names such as "arte HD") for such streams.
    bugfix: fixed computation of value of total progress bar for
      multiple jobs running.
    bugfix: multiplexer, adding new attachments: when the GUI checks
      if there's an attachment with the same name it will now
      disregard disabled attached files.
    new feature: multiplex tool: the dialog asking the user what to
      do with dropped files (add to current settings, add to new
      settings etc.) now remembers the previous decision and defaults
      to it the next time it's shown.
    new feature: tabs can now be closed by pressing the middle mouse
    * mkvpropedit: bugfix: fixed a crash when the selector used
      for `--tags` is invalid.
* Tue Jun 06 2017
  - Adjust usage of gccN-c++ for Leap42 and SLE12
* Tue May 30 2017
  - Update to version 12.0.0
    * MKVToolNix GUI: new feature: the key combination
      Ctrl+Shift+Space will now toggle the selection of the current
      item in all tree views where multiple selections are allowed.
    new feature: chapter editor: added the extension `*.cue`
      to the "open chapter file" dialog.
    bugfix: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.
    bugfix: 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.
    bugfix: 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".
    new feature: 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.
    new feature: 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; hibernating, sleeping
      and shutting down the computer.
    new feature: 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.
    * mkvmerge: New feature: 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.
    new feature: added an option `--no-date` that prevents the "date"
      field from being written to the segment information headers.
    new feature: FLAC reader: added support for handling embedded
      pictures as attachments.
    new feature: MP4 reader: Added support for parsing the "COLR"
      atom and including its values as track headers.
    bugfix: 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.
    bugfix: 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. This prevents the AAC packetizer from
      mis-detecting it in its own attempt to identify the mode.
    bugfix: MPEG TS reader: valid MPEG transport streams that start
      with an h.264/h.265 start code were not recognized as a
      supported file type.
    bugfix: MPEG TS reader: fixed a potential read access from
      invalid memory addresses in the code parsing the program
      map table (PMT).
    bugfix: 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.
    bugfix: 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.
    bugfix: MP4 reader: the `nclx` colour type of the `colr` atom is
      now recognized, too.
    bugfix: AAC parser: fixed mis-detection of certain data as valid
      ADTS AAC headers resulting in memory allocation failures.
    bugfix: AVC/h.264 parser: mkvmerge will now ignore bogus timing
      information in the sequence parameter sets.
    bugfix: AVC/h.264 & HEVC/h.265 parsers: all trailing zero bytes
      will now be removed from NALUs.
    bugfix: HEVC/h.265 parser: fixed copying the
      `bitstream_restriction_flag` and all dependent fields in the VUI
      parameters of the sequence parameter sets.
    bugfix: HEVC/h.265 parser: fixed the calculation of the number of
      parameter set arrays in the HEVCC data structure stored in
    * mkvpropedit: bugfix: header editor: added support for editing the
      "date" segment information field.
* Tue Mar 28 2017
  - Update to new release 10.0.0
    * mkvmerge: new feature AVC/h.264 and HEVC/h.265 parser: mkvmerge
      will now drop all frames before the first key frame as they
      cannot be decoded properly anyway.
    new feature HEVC/h.265 parser: added a workaround for invalid
      values for the "default display window" in the VUI parameters
      of sequence parameter sets.
    bugfix MP4 reader: fixed track offsets being wrong in certain
      situations regarding the presence or absence of edit lists
      ('elst' atoms) & composition timestamps ('ctts' atoms).
    bugfix MP4 reader: offsets in "ctts" are now always treated
      as signed integers, even with version 0 atoms.
    bugfix Matroska reader: fixed handling BlockGroups and
      SimpleBlocks with negative timestamps.
    bugfix MP3 packetizer: the MP3 packetizer will no longer drop
      timestamps from source containers if they go backwards.
      This keeps A/V in sync for files where the source was in sync
      even though their timestamps aren't monotonic increasing.
    bugfix AVC/h.264 parser: mkvmerge will now drop timestamps
      from the source container if no frame is emitted for that
    bugfix HEVC/h.265 parser: mkvmerge will now drop timestamps
      from the source container if no frame is emitted for that
    * mkvinfo: the timestamps of SimpleBlocks with negative
    timestamps are now shown correctly.
    * mkvextract: SSA/ASS: fixed extraction when the "Format"
    line in the "[Events]" section contains less fields than the
    default for SSA/ASS would indicate.
* Mon Feb 20 2017
  - Update to new release 9.9.0
    * mkvmerge: AC-3 handling: some source files provide timestamps
      for audio tracks only once every n audio frames. In such
      situations mkvmerge was buffering too much data resulting in
      a single gap in the timestamps of one frame duration after frame
      number n - 1 (the second audio timestamp read from the source
      file was used one output frame too early).
    bugfix MP4 reader: mkvmerge was only reading a small part of MP4
      DASH files where the first "moov" "mdat" atoms occur before the
      first "moof" atom.
    bugfix MP4 reader: edit list ("edts" atoms) that are part of the
      "moof" atoms used in MP4 DASH files weren't parsed. Instead the
      edit lists from the main track headers inside the "moov" atom
      were used.
    bugfix MP4 reader: when an MP4 DASH file contained both normal
      chunk offset table in their regular "moov" atoms, a
      sample-to-chunk table ("stsc" atom) whose last entry had a
      "samples per chunk" count greater than 1 and DASH "trun" atoms,
      then mkvmerge was calculating wrong positions the frame content.
    bugfix MP4 reader: mkvmerge couldn't deal with the key frame index
      table having duplicate entries. The result was that only key
      frames up to and including the first duplicate entry were marked
      as key frames in the output file. All other frames weren't, even
      though some of them were referenced from the key frame table
      after the first duplicate entry.
    bufix MP4 reader: when an MP4 file contained more than one copy of
      the "moov" atom (the track headers etc.), mkvmerge was parsing
      them all adding tracks multiple times.
    bugfix MP4 reader: fixed an integer overflow during the timestamp
      calculation leading to files with wrong timestamps. Such files
      could not be played back properly by most players.
    bugfix MPEG TS reader: if the PMT lists a DVBSUB track, mkvmerge
      will now recognize it without having to find a packet for it
      within the probed range.
    bugfix splitting by parts (both the "timestamps" and the "frames"
      variants): fixed the calculation of track statistics tags. When
      calculating the duration the skipped portions weren't taken into
      account leading to a too-high duration. As a consequence the BPS
      tag (bits per second) was wrong, too.
    bugfix reading files with DVB/HDMV TextSV subtitle tracks with
      invalid CodecPrivate caused mkvmerge to abort with an error
      from boost::format about the format string not having enough
    bugfix: fixed misdetection of certain AC-3 files as MP3 files
      which led to an error message that
      "the demultiplexer could not be initialized".
    bugfix: fixed huge memory consumption when appending big Matroska
      files with sparse tracks (e.g. forced subtitle tracks).
      The Matroska reader will now queue at most 128 MB of data.
    bugfix MP4 reader: the timestamps of all multiplexed tracks will
      now be 0-based properly.
    bugfix MP4 reader: the DTS-to-PTS offsets given by the "ctts"
      atoms are now applied for all tracks containing a "ctts" atom,
      not just h.264 & h.265 tracks.
    * Some new features and enhancements
  - Now required for man pages:
    libxslt-tools, docbook-xsl-stylesheets  and po4a
* Fri Jan 27 2017
  - Update to new release 9.8.0
    * 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.
    bug fix: the MPEG transport stream reader was using an outdated
    format for the "CodecPrivate" element for HDMV TextST subtitles.
    This has been updated to the current format which only contains
    the "dialog style element". Existing Matroska files using this
    outdated scheme can be fixed by running them through mkvmerge.
    bug fix: files smaller than 4 bytes were wrongly identified as
    MPEG transport streams.
    bug fix: if a codec delay is set for a track in the input file,
    it is kept. Fixes #1849. bug fix: fixed that the error message
    "not enough space on disk" was shown twice on some operating systems.
    teletext subtitle bug fix: fixed the handling of DVB teletext subtitles
    signaled with data unit ID 0x02 and that contain pages from multiple magazines.
    bug fix: when using --track-order without specifying all tracks,
    the track numbers could end up in a way the user did not expect.
    Now mkvmerge will always assign track numbers for those tracks
    that are listed in --track-order first. The other tracks are
    assigned numbers afterwards. Fixes the second part of #1832.
    bug fix: when reading Matroska files the movie title was always
    taken from the first Matroska source file, even if that file
    didn't have a title set. Fixes one part of #1832.
    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.
    The command line option "--check-for-updates" has been removed.
    * 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.
    certain failures during file identification that can be
    traced to broken installations 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 fixed.
    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.
    multiplex tool bug fix: under certain circumstances the GUI was
    creating invalid JSON files when starting to multiplex resulting
    in an error message ("JSON option files must contain a JSON
    array consisting solely of JSON strings").
    re-worked the startup code not to use lock files when trying to
    open a socket for communicating with an already-running instance.
    This aims to prevent situations with stale lock files not being
    cleaned up and the GUI not starting anymore as a result.
    This might fix or prevent issues like #1805.
    * A lot of new features and enhancements, please refer to
  - Rebased disable-update-check.patch
  - spec file cleanup
  - Adjusted BuildRequires
    * Since 9.7.1 QT >= 5.3 is required
    * Since 9.7.1 a c++ compiler with some c++14 features is required
      e.g. gcc >= 4.9 or clang >= 3.4
* Wed Nov 30 2016
  - Update to new release 9.6.0
    * mkvmerge: bug fix: mkvmerge was entering endless loops under
      certain conditions when appending files.
      MPLS parser bug fix: fixed reading the "in" & "out"
      timestamps for "play items". This bug resulted in mkvmerge
      not reading the correct range from the referenced M2TS file
      under certain rare circumstances.
    * MKVToolNix GUI: job output tool bug fix: the button for
      acknowledging warnings & errors wasn't properly disabled when
      the user used outside methods of acknowledging them
    * mkvextract: VobSub bug fix: mkvextract will add a "langidx"
      line to the .idx file upon extraction.
    * mkvmerge & mkvextract: added support for HDMV TextST subtitles.
* Thu Oct 27 2016
  - Update to new release 9.5.0
    * mkvmerge: bug fix: The Ogg/OGM reader did not recognize Opus
      files with comment headers anymore.
      WAV reader bug fix: the track properties (channels, samplerate)
      for DTS and AC-3 in WAV will now be derived from the decoded
      bitstream headers instead of the WAV file header as the latter
      is often incorrect.
      WAV reader bug fix: fixed detection and merging of DTS in WAV
      that uses the 14-bytes-in-16-bytes packing method.
      MPEG transport stream reader bug fix: fixed mis-detection of
      certain h.264 files as MPEG transport streams.
      MPEG transport stream reader bug fix: fixed the handling of
      Blu-ray PCM audio with an odd number of channels by removing
      their alignment bytes.
      h.264 elementary stream handling bug fix: if mkvmerge ever
      encounters changing SPS or PPS NALUs (ones where their ID has
      been encountered before with different settings) in the h.264
      then it will prepend all following key frames with all
      currently active SPS and PPS NALUs. This enables playback from
      arbitrary key frames even if they require other SPS or PPS
      settings than the ones stored in the AVCC in CodecPrivate.
      VobSub handling bug fix: mkvmerge and mkvextract will now
      update the duration stored in the SPU bitsream with the
      duration from the container level if it differs at least 1ms.
    * mkvprpedit, MKVToolNix GUI: Added support for "field order"
      video track header element.
  - Use GPG signature for verification.
* Fri Sep 16 2016
  - Update to new release 9.4.2:
    * mkvmerge: bug fix: using very large --sync values with certain
      container formats was causing mkvmerge to abort muxing.
      bug fix: fixed an invalid memory access (use after free)
      during global destruction phase.
      bug fix: HEVC parser: fixed three invalid memory accesses.
      bug fix: MP4 reader: fixed an invalid memory access
      bug fix: AAC reader: fixed mkvmerge throwing an uncaught
      exception due to the sample rate being 0.
      bug fix: MP4 reader: an error message will be printed
      instead of an uncaught exception when an invalid atom chunk
      size is encountered during resync.
      bug fix: AVC & HEVC readers: the readers will now refuse to
      handle files where the detected pixel width or height is
      equal to or less than 0.
* Thu Sep 01 2016
  - Update to new upstream release 9.4.0:
    * MKVToolNix GUI: merge tool bug fix: the automatic adjustments
      to the output file name based on the track types selected for
      muxing and the mechanism for keeping output file names unique
      had been broken since release v9.3.0.
      chapter editor bug fix: overly long chapter names don't cause
      the GUI's window to become overly wide anymore.
    * mkvmerge: bug fix: mkvmerge does no longer emit a warning if no
      comment header packet is found when reading tracks from
      Ogg/OGM files.
      bug fix: VP8 in Ogg: fixed dropping the first frame and the
      timestamp calculation.
      bug fix: when appending files mkvmerge wasn't starting clusters
      on video key frame anymore for the first and all following
      appended files.
      DTS bug fix: if present mkvmerge will use an XLL extension's
      sample rate information as the sample rate to put into
      the track headers.
    * mkvpropedit: bug fix: mkvpropedit will no longer say that it's
      writing the changes if only attachment changes are specified
      and none of the specified attachments can be found.
    * Some enhancements, please refer to the changelog within the
* Fri Jul 15 2016
  - Update to new upstream release 9.3.1:
    * libebml >= 1.3.4 and libmatroska >= 1.4.5 are now required
    * A lot of bugfixes and new features, new mkv elements are
      supported, for a list of all changes, please refer to the
      changelog provided by the package.
* Tue May 31 2016
  - Update to new upstream release 9.2.0:
    * mkvmerge: bug fix: the "interval" chapter generation mode was
    always creating one chapter too many.
    bug fix: if a certain number of chapters had been generated with
    - -generate-chapters then mkvmerge wasn't replacing the void
    placerholder with the actual chapters.
    bug fix: fixed detection of (E-)AC-3 in MPEG TS files with
    unusual stream types (e.g. 0x87) but with (E-)AC-3 PMT
    * mkvmerge, mkvextract: bug fix: fixed handling of Big Endian PCM
    with a bit depth other than 16, 32 or 64 bits/sample. Other
    formats were using the Little Endian codec ID, but their content
    was actually not byte-swapped to match it. Now those other bit
    depths are byte-swapped to Little Endian, too.
    * MKVToolNix GUI: merge tool bug fix: the track column "default
    track in output" wasn't taking into account if the track had its
    "default track" flag set to "no" in the source file. This would
    result in the column showing "yes" in certain situations even
    though mkvmerge would assign "no".
    * Some other improvements, some enhancements and other bugfixes,
    please refer to the changelog file provides with the package.
* Mon Apr 25 2016
  - Update to new upstream release 9.1.0:
    * mkvmerge: bug fix: AVC/h.264: fixed handling of interlaced frames
    with bottom field first.
    bug fix: mkvmerge will no longer abort reading a Matroska file
    with a structural error right before the first cluster.
    bug fix: the "text_subtitles" property of the JSON/verbose
    identification modes was always set to true for all subtitle
    tracks, even for those that aren't text subtitles (VobSub, PG).
    bug fix: the language code signaled in the MPEG TS PMT is taken
    into account when selecting the character encoding to use
    during decoding of the teletext subtitles, not just the
    "national character set" stored in the teletext page headers.
    * MKVToolNix GUI: bug fix: Fixed huge memory consumption in the
    JSON library by updating said JSON library.
    bug fix: In merge-tool: when adding playlists the GUI won't ask
    the user whether or not to scan if there's only a single
    playlist in that directory.
* Mon Mar 28 2016
  - Update to new upstream release 9.0.1:
    * mkvmerge: bug fix: regression in v9.0.0: the text subtitle
    packetizer was wrongfully assuming an encoding of UTF-8 if none
    was given instead of assuming the system's encoding. Fixes #1639.
    bug fix: if too many chapters had been generated with
    - -generate-chapters then mkvmerge created a bogus entry in the
    meta seek element and did not actually write the chapters to the
    bug fix: the DTS packetizer was setting the number of
    channels wrong sometimes when reducing to the DTS core. It was
    using the number of channels including the extensions instead of
    the channels of the core only.
* Mon Mar 28 2016
  - Update to new upstream release 9.0.0
    * mkvmerge: bug fix: fixed two more issues in the conversion of
    teletext subtitles to SRT subtitles.
    * mkvmerge: MP4/QuickTime reader: audio tracks with the FourCC
    "lpcm" are muxed as A_PCM/INT/LIT instead of A_QUICKTIME.
    * mkvmerge: bug fix: MP4/QuickTime reader: audio tracks can contain
    two instances of certain header fields in the STSD atom;
    mkvmerge now uses the v2 structure over v0, if present.
    * mkvextract: new feature: implemented the extraction of Big
    Endian PCM (codec ID A_PCM/INT/BIG) to WAV files. The content will
    be byte-swapped into Little Endian PCM in the process.
    * mkvmerge: enhancement: Big Endian PCM tracks will now be
    byte-swapped into Little Endian PCM, and the codec ID
    A_PCM/INT/LIT will be used, as many players do not support BE PCM
    inside MKVs.
* Mon Feb 22 2016
  - Update to new upstream release 8.9.0
    * gui: the default font size adjustment has been. Deactivated for
    the time being as it causes problems on high DPI Displays.
    * gui: ampersands in file names were shown as keyboard shortcuts
    in tab titles in various tools
    * gui: add ability (menu entry) for removing chapters from an
    existing Matroska file.
    * Polish translation provided
* Sun Jan 10 2016
  - Update to upstream release 8.8.0:
    * MKVToolNix GUI: bug fix: when using one of the
      "select all tracks (of type…)" actions the "properties" column
      didn’t show the selection.
      bug fix: the paths used in the variables and the executable are
      converted to the platforms native path separators.
    * mkvmerge: bug fix: fixed a mis-detection of an MPEG-2 video
      elementary stream as a TrueHD file which then caused a
      segmentation fault.
      bug fix: Matroska attachments with the same name, size and MIME
      type were not output during file identification.
      bug fix: fixed TrueHD detection both as raw streams as well as
      inside other contains if the stream does not start with a
      TrueHD sync frame.
    * Some GUI enhancements and new features, see full changelog:
  - some spec file cleanup
* Thu Jan 07 2016
  - Update to upstream release 8.7.0:
    * all: reversion of a change: several ISO 639-2 codes of languages
      that are very old and not spoken anymore have been re-added
      due to feedback from users who did have a use for such codes.
      reversion of a change: all of the tools will write a byte-order
      mark (BOM) to text files encoded any of the UTF-* schemes again.
    * mkvmerge: bug fix: fixed the key frame detection for VP9 video
      bug fix: chapters were output as both "chapters" and
      "track_tags" in JSON identification mode.
      bug fix: AAC with low sampling frequencies was sometimes
      mis-detected with the wrong profile preventing appending it
      to other AAC tracks.
      bug fix: the progress calculation was sometimes outputting
      negative numbers when appending Matroska files whose timestamps
      don’t start at 0.
      bug fix: fixed the decisions whether or not to write the last
      frame of a track as a BlockGroup or a SimpleBlock and whether
      or not to write a block duration for that frame.
      bug fix: the Matroska reader now uses TrueHD-specific code
      when reading Matroska files. This can fix things like wrong
      frame type flags.
    * MKVToolNix GUI: bug fix: relative file names given on the
      command line were interpreted as being relative to the user’s
      home directory.
      bug fix: the "split mode" drop-down box got reset to
      "do not split" each time the preferences dialog was closed
      with the "OK" button
    * And a lot more enhancements and bugfixes, see full changelog:
* Sat Dec 05 2015
  - Update to upstream release 8.6.1:
    * all: MKVToolNix now requires gcc 4.8.0 or later or clang 3.4 or
      later for compilation.
    change: none of the tools will write a byte-order mark (BOM) to
    text files encoded any of the UTF-* schemes anymore.
    * mkvmerge: bug fix: the VC-1 handlig code was duplicating the
      first sequence headers with each mux.
    enhancement: added JSON as an output format for file type
    bug fix: fixed two issues causing mkvmerge to write invalid data
      when updating track headers.
    bug fix: the change to do a deeper file analysis if no seek head
      was found was causing huge increases in file type detection time
      as popular tools like x264 don’t write seek heads. The way
      elements at the end are searched has been changed to only scan
      the last 5 MB of the file instead of iterating over every
      level 1 element from the beginning of the file.
    * MKVToolNix GUI: bug fix: the options for linking to the
      next/previous segment UID were wrong.
    bug fix: the program changes its working directory to the
      user’s profile/home directory on startup allowing the removal of
      its installation folder even if a program started by the GUI
      (e.g. a web browser) is still running.
    bug fix: in certain situations the modified file would not contain
      a seek head before the first cluster anymore resulting in most
      players not finding elements such as attachments or the index
      located at the end of the file anymore.
    * Some other enhancements and bugfixes, see full changelog:
  - Split package into commandline- (base) and gui-package,
    reduces overhead when installing on a headless system.
  - Replaced sed in prep with disable-update-check.patch to disable
    update check on startup (not needed with a package system).
  - Added mkvtoolnix-use-system-boost.patch from fedora to fix includes
    when building against boost from system.
* Thu Nov 05 2015
  - Update to upstream release 8.5.2:
    * mkvmerge: bug fix: fixed an endless loop when updating track
      headers caused by the fix for "Re-rendering track headers.
    bug fix: mkvmerge no longer creates a "next segment UID" field
      in the last file when splitting and segment linking is active.
    bug fix: fixed the values of the "previous/next segment UID"
      elements when splitting by parts with segment linking enabled.
    * MKVToolNix GUI: bug fix: the file/track columns aren't resized
      to fit their content when expanding/collapsing tree node
      anymore. Such expansion also happened when moving entries with
      the "move up/down" buttons.
* Thu Oct 22 2015
  - Update to upstream release 8.5.1 (security update):
    * build system: libEBML v1.3.3 and libMatroska v1.4.4 are now
    required due to important fixes for invalid memory accesses in
    those two releases. The copies included in the MKVToolNix source
    code have been updated to those releases as well.
    * MKVToolNix GUI: bug fix: the "save file" dialogs did not have
    the currently entered file name pre-selected anymore.
    bug fix: fixed a crash when loading corrupted
    job settings.
    bug fix (Linux): the function "open folder" was
    inserting a superfluous leading slash in the directory name.
    * mkvmerge: bug fix: updating the track headers wasn't working in
    some rare cases (corresponding error message "Re-rendering track
    headers: data_size != 0 not implemented yet").
  - Disable default setting for checking for updates (nonsense on a
    package system)
* Sun Oct 18 2015
  - Updated to version 8.5.0:
    * Modified .spec to also install translated manpages.
    * A lot of small bugfixes and enhancements.
    * MKVToolNix GUI: merge tool bug fix: the cropping parameters were
    not converted into parameters for mkvmerge at all.
    * mkvmerge: enhancement: the verbose identification for MP4 files
    will now derive basic audio parameters of MP3 and AC3 tracks
    from the bitstream instead of relying on the values in the
    track headers.
    bug fix: PCM tracks: if the number of samples per
    packet varies then no default duration will be written.
    * all: several ISO 639-2 codes of languages that are very old and
    not spoken anymore have been removed.
    new feature: added a Catalan translation of
    the man pages.
* Tue Sep 22 2015
  - Updated to version 8.4.0:
    * MMG has been removed.
    * Dropped wxWidgets dependencies (new gui uses QT).
    * A lot of bugfixes and enhancements of the gui and mkvmerge
    * mkvmerge: bug fix: calculating of delay for audio garbage data
    got fixed.
    * all: bug fix: parsing of strings containing negative values or
    timecodes was broken on 32-but architectures.
    * mkvmerge: bug fix: number of channels and the sample rate
    reported for DTS in MPEG streams was 0.
* Sun Aug 16 2015
  - Update to new upstream release 8.3.0
    * many small GUI bug fixes and improvements
    * mkvmerge: bug fix: fixed handling of MPEG transport streams
    where all PATs and PMTs have CRC errors.
    * mkvmerge: bug fix: the MPEG-1/2 video code was causing an
    illegal memory access under certain conditions.
    * mkvmerge: bug fix: fixed recognition of (E)AC3 audio tracks
    using a FourCC of "ec-3"
    * mkvmerge: bug fix: fixed codec identification for MP2 audio read
    from MPEG PS/TS.
    * mkvmerge: bug fix: fixed key frame designation for video tracks
    in MP4 DASH files.
* Wed Aug 05 2015
  - Update to version 8.2.0:
    * Fix mkvmerge codec identification for MP2 audio.
    A LOT more bugfixes especially in the GUI. See ChangeLog:
* Fri May 29 2015
  - Update to version 7.9.0:
    * Fix build with boost 1.58.0.
    * build system: configure will now check for Qt by default.
    * A couple of important bugs have been fixed, e.g. a very old bug
    in handling MPEG-1/2 video preventing the detection of such
    tracks; if --sync was used at the same time as --default-duration
    then --sync was ignored; mkvinfo’s exit codes were wrong (this
    may trip up frontends using mkvinfo!); handling of E-AC3 in MPEG
    transport stream in certain situations.
* Sat Mar 28 2015
  - Update to new upstream release 7.8.0
    * mkvmerge: Fixed recognition of E-AC3 audio tracks in MPEG TS
    streams if they use the type ID 0xa1 (and the same for DTS tracks
    stored with type ID 0xa2).
    * mkvmerge: new feature: mkvmerge will now recognize TrueHD tracks
    inside MPEG transport streams that contain an AC3 core as
    consisting of two tracks.
    * mkvmerge: new feature: mkvmerge will now recognize TrueHD+AC3
    files as consisting of two tracks.
* Tue Feb 10 2015
  - Update to new upstream release 7.6.0
    * all programs: bug fix: Since release 7.0.0 the wrong exit code
    was used when warnings were finished (0 instead of 1).
    * mkvmerge: bug fix: Appending chapters with the same chapter UID
    was dropping all sub-chapters from the one of the two merged
    chapters. Now the sub-chapters are merged recursively as well.
    * mkvmerge: bug fix: The wrong Codec ID was written when reading
    PCM tracks from Matroska files in Big Endian byte order.
    * all: new feature: added a Serbian (Latin) translation of the
    programs by Danko (see AUTHORS).
    * mkvmerge: bug fix: If splitting was active and AC3 tracks read
    from Matroska files were shorter than a split point then the
    following output file would contain an AC3 packet with the
    timecode of 00:00:00 somewhere in the middle.
    * mmg: bug fix: If a chapter track from a Matroska file is
    selected then the »language« drop-down box is disabled.
    * mmg: bug fix: When scanning for play lists the window presenting
    the results listed some properties in an unescaped way (e.g.
    »\s« instead of spaces).
    * mmg: bug fix: When adding MPLS files mmg was only offering to
    scan for more playlists if there were at least two additional
    MPLS files present. This has been fixed to one MPLS file (in
    addition to the one just added).
* Sun Feb 01 2015
  - Update to new upstream release 7.5.0
    * mkvmerge: Fixed reading MPEG transport streams in which
    all PATs and/or PMTs have CRC errors.
    * mkvmerge: Implemented support for MP4 DASH files.
    * mkvmerge: Implemented reading MPEG-H p2/HEVC video
    tracks from MP4 files.
    * mkvmerge: Implemented support for AAC in LOAS/LATM multiplex if
    read from MPEG transport streams or raw LOAS/LATM AAC files.
    * mkvmerge: Added support for recognizing H.265/HEVC video tracks
    in MPEG transport streams.
* Sat Dec 13 2014
  - update to upstream release 7.4.0
    * Implements support for PCM in MPEG program (.vob – DVDs) and
    transport streams (.ts, .m2ts – Blu-rays, television broadcasts)
    as well as for teletext subtitles in MPEG tranport streams.
    Apart from that a lot of work has gone into the new GUI.
    * Bugfixes for muxing HEVC or teletext subtitles
