Log message:
mkvtoolnix: Fix runtime crash on SunOS.  Bump PKGREVISION.

Log message:
mkvtoolnix: updated to 29.0.0

Version 29.0.0 "Like It Or Not"

Important notes
* The string formatting library used was switched from boost::format to
  [fmt](http://fmtlib.net/). See the section "Build system changes" for
  details.

New features and enhancements
* MKVToolNix GUI: added an option in the preferences for disabling automatic
  scaling for high DPI displays.
* MKVToolNix GUI: the GUI will now prevent the system from going to sleep
  while the job queue is running. This feature is implemented for macOS,
  Windows and Linux/Unix systems where the org.freedesktop.login1.Manager
  D-Bus interface is available.

Bug fixes
* mkvmerge: chapter generation: the start timestamps of chapters generated in
  intervals was wrong for files whose smallest video timestamp was bigger than
  0.
* mkvmerge: MP4 reader: fixed handling of atoms whose size exceeds the parent
  atom's size.
* mkvmerge, MKVToolNix GUI's chapter editor: the chapter name template will
  now also be used when reading Ogg-style chapter files with empty chapter
  names.
* mkvextract: 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: 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 position.
* MKVToolNix GUI: Windows: the application manifest is now included properly
  so that Windows actually recognizes it.

Build system changes
* Qt's D-Bus implementation is now required for building on systems other than
  macOS and Windows,
* The boost::format library is not used anymore.
* The [fmt library](http://fmtlib.net/) is now required. Versions 3 and
  newer are supported. As not all Linux distributions include packages for the
  library, its release 5.2.1 comes bundled with MKVToolNix. The configure
  script will check for a system version of the library and use it if present
  and recent enough. Otherwise it will fall back to the bundled version and
  link that statically.

Log message:
Recursive revbump from hardbuzz-2.1.1

Log message:
mkvtoolnix: update to 28.2.0. security fix.

* 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.

Log message:
mkvtoolnix: updated to 28.1.0

Version 28.1.0 "Morning Child":

Bug fixes

* mkvmerge: 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.
* mkvmerge: 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.
* mkvmerge: 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: info tool: the tool will no longer stop scanning elements
  when an EBML Void element is found after the first Cluster element.

Log message:
mkvtoolnix: updated to 28.0.0

Version 28.0.0 "Voice In My Head":

New features and enhancements
* mkvmerge: AV1 parser: updated the code for the finalized AV1 bitstream
  specification.
* mkvmerge: AV1 packetizer: updated the code for the finalized AV1-in-Matroska
  & WebM mapping specification.
* mkvmerge: AV1 support: the `--engage enable_av1` option has been removed
  again.
* mkvmerge: MP4 reader: added support for AV1.
* mkvmerge: DTS: implemented dialog normalization gain removal for extension
  substreams.
* mkvmerge, mkvextract: simple text subtitles: added a workaround for simple
  text subtitle tracks that don't contain a duration.
* mkvextract: added support for extracting AV1 to IVF.
* mkvextract: 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.
* mkvmerge: VP9: mkvmerge will now create codec private data according to the
  VP9 codec mapping described in the WebM specifications.
* MKVToolNix GUI: automatic scaling for high DPI displays is activated if the
  GUI is compiled with Qt ≥ 5.6.0.
* MKVToolNix GUI: added a menu item ("Help" → "System \ 
information") for
  displaying information about the system MKVToolNix is running on in order to
  make debugging easier.
* MKVToolNix GUI: 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.

Bug fixes
* mkvmerge: JSON identification: fixed a bug when removing invalid UTF-8 data
  from strings before they're output as JSON.
* mkvmerge: MP4/QuickTime reader: fixed handling of PCM audio with FourCC
  `in24`.
* mkvmerge: 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.
* mkvextract: 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: 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.

Log message:
mkvtoolnix: updated to 27.0.0

Version 27.0.0 "Metropolis":

New features and enhancements
* mkvmerge: 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.
* MKVToolNix GUI: multiplexer: adjusted & added controls for mkvmerge's new
  feature of being able to adjust chapter timestamps.
* MKVToolNix GUI: 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.

Bug fixes
* mkvmerge: 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: fixed a leak of Windows font resources leading to a general
  slowdown and subsequent crash.

Log message:
mkvtoolnix: updated to 26.0.0

Version 26.0.0 "In The Game":

New features and enhancements
* mkvmerge: chapter generation: if the name template given by
  --generate-chapters-name-template is empty, no names (ChapterDisplay
  master elements with ChapterString/ChapterLanguage children) will be
  generated for the chapter atoms.
* mkvmerge: chapters: chapter names generated from MPLS files will now use the
  name template if one is set via --generate-chapters-name-template.
* mkvmerge: 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 (e.g. Matroska or MP4 files).
* MKVToolNix GUI: the font size in the tool selector on the left will scale
  with the font size the user selects in the preferences.
* MKVToolNix GUI: 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.
* MKVToolNix GUI: 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
  (either because automatic generation is enabled or if chapters are generated
  for MPLS playlists).
* MKVToolNix GUI: chapter editor: if the chapter name template is empty,
  chapters will be generated without names.
* MKVToolNix GUI: chapter editor: added an option to remove all chapter names
  to the "additional modifications" dialog.

Bug fixes
* mkvmerge: Matroska reader: fixed wrong timestamps when appending Matroska
  files where the second Matroska file's first timestamp is bigger
  than 0.
* mkvmerge: MP4 reader: fixed division by zero errors during file
  identification if the timescale is 0 in the MVHD atom.
* mkvmerge: 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: info tool: under certain circumstances "cues" were \ 
shown at
  the wrong level (inside the previous master element instead of on level 1).
* MKVToolNix GUI: 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.

Build system changes
* An AppStream metadata file will be installed in $prefix/share/metainfo.
