mkvtoolnix: updated to 49.0.0

Version 49.0.0 "Sick Of Losing Soulmates" 2020-08-02

New features and enhancements

* mkvmerge: added support for copying the new track header elements
  `BlockAddIDName`, `BlockAddIDType`, `BlockAddIDValue` and
  `BlockAddIDExtraData` from Matroska files if they exist.
* mkvinfo: added support for the new track header elements
  `BlockAdditionMapping`, `BlockAddIDName`, BlockAddIDType`, `BlockAddIDValue`
  and `BlockAddIDExtraData`.
* MKVToolNix GUI: multiplexer: the list of recent directories can now be
  edited in the preferences → "Multiplexer" → "Destination file
  name".
* MKVToolNix GUI: preferences: the values in the various "predefined \ 
values"
  lists can now be re-ordered freely by dragging & dropping.

Bug fixes

* mkvmerge: Matroska reader: when reading tracks (e.g. a subtitle track) from
  Matroska files with their `default track` flag set to `yes`, and when
  overwriting those via the command line to `no`, `mkvmerge` would not promote
  additional tracks of the same type from other files (e.g. another subtitle
  track from an SRT file).
* mkvmerge: SRT reader: empty lines inside entries were doubled.
* mkvmerge: subtitles: when calculating the rounded duration of each entry the
  error from rounding the corresponding timestamp will be taken into
  account.
* mkvextract: SSA/ASS extraction: mkvextract is no longer inserting empty
  lines before the `Dialogue:` lines.
* mkvextract: USF subtitles: start & end timestamps were too high by a factor
  of 1.000.000.
* MKVToolNix: info tool: when saving to a text file the checkbox "Save as
  default for saving output to text files" did nothing.
* MKVToolNix: info tool: when saving to a text file in "all elements in a
  tree-like structure" mode, the GUI always stopped at the first cluster
  regardless of the setting of the "verbosity" option.
* MKVToolNix GUI: preferences: when tooltips were disabled the dialogs for
  adding new entries to the various "predefined values" lists were missing
  their texts.
* Windows installer: the images are shown again.
* configure: fixed detection of QtDBus.

Build system changes

* libMatroska v1.6.1 is now required. The bundled version has been updated to
  that version.

mkvtoolnix: updated to 48.0.0

Version 48.0.0 "Sick Of Losing Soulmates" 2020-06-27

New features and enhancements

* mkvmerge: AC-3: file identification will report AC-3 tracks encoded in Dolby
  Surround EX as codec "AC-3 Dolby Surround EX".
* MKVToolNix GUI: multiplexer: on new installations the GUI will now recognize
  all known ISO 639-2 language codes in file names by default instead of only
  the top 100 of languages by native speakers.
* MKVToolNix GUI: multiplexer: on new installations the list of "often used
  languages" will by default only contain certain agnostic ones ("multiple
  languages", "no linguistic content", "reserved for local \ 
use", "uncoded
  languages"), "English" and the default user interface language. \ 
The "list of
  spoken languages by native speaks" isn't used anymore.
* MKVToolNix GUI: header editor: added an option to remove all attachments to
  the tree context menu.
* MKVToolNix GUI: while the GUI is running it will remember the last page that
  was selected when the preferences dialog is closed. Upon re-opening the
  preferences that page will be selected by default.

Bug fixes

* mkvmerge: fixed a segmentation fault when exiting prematurely due to write
  errors such as the destination having run out of space.
* mkvmerge: DTS: fixed wrong channel count for DTS tracks with XCh
  extensions.
* mkvmerge: MPEG TS reader: fixed detecting h.264/AVC and h.265/HEVC tracks
  that consist of only a single frame.
* mkvmerge: MPEG TS reader: fixed handling of unbounded PES sizes for tracks
  that consist of only a single PES packet.
* mkvmerge: MPEG TS reader: PGS subtitle tracks are now exempt from the
  "detect bogus subtitle timestamps" heuristic which could lead to some PGS
  subtitles not being timestamped correctly. Symptoms were that they were
  shown at the wrong time or that they were shown indefinitely.
* mkvmerge: MPEG TS reader: when reading MPLS playlists the start timestamps
  of a play items were handled wrong: all the timestamps of packets read were
  compared to that start timestamp, dropping those packets whose timestamps
  were smaller than the play item's start timestamp. The correct behavior is
  to accept all packets as soon as the first one with a timestamp equal to or
  larger than the play item's start timestamp is encountered. This could
  result in PGS subtitle entries located right at the start of the play item
  being garbled/lost as they consist of multiple PES packets for which some
  timestamps are often slightly smaller.
* mkvmerge: MPEG TS reader: when reading MPLS playlists mkvmerge will no
  longer read the whole M2TS files they reference, processing only the packets
  lying inside the timestamp range given by the playlists's play item's start
  & end timestamps. Instead mkvmerge will use the index information present in
  corresponding clip information (CLPI) files in order to seek to the nearest
  file position of the play item's start timestamp. Additionally mkvmerge will
  simply stop processing a file once the end timestamp is seen. This change
  greatly speeds up processing files from which only small portions must be
  read.
* mkvmerge: WavPack: fixed support for files created by v5 of the
  program. Checksums, DSD audio data and non-standard sampling rates are
  handled correctly. Patch by David Bryant.
* MKVToolNix GUI: multiplexer: fixed the cursor being positioned wrong after
  entering or pasting characters that aren't allowed in file names into the
  "destination file" control.

Build system changes

* libEBML v1.4.0 and libMatroska v1.6.0 are now required.

Other changes

* The source code repository's main development branch was renamed to `main`.

mkvtoolnix: updated to 47.0.0

Version 47.0.0 "Black Flag"

New features and enhancements

* mkvmerge: chapters: mkvmerge can now read chapters from DVDs if the user
  specifies the path to a DVD folder structure via the `--chapters …`
  parameter. By default chapters from the first title will be imported. This
  can be changed by append `:<title number>` to the file/directory name in the
  `--chapters …` argument, e.g. `--chapters /srv/dvds/BigBuckBunny/VIDEO_TS:3`
  This feature requires mkvmerge to have been built with the `libdvdread`
  library.
* mkvmerge: added `--engage append_and_split_flac` that enables mkvmerge to
  append and split FLAC tracks, restoring pre-v45 behavior.  The resulting
  tracks will be broken: the official FLAC tools will not be able to decode
  them and seeking will not work as expected.
* MKVToolNix GUI: multiplexer: added support for mkvmerge's new support for
  reading chapters from DVDs if both have been built with the `libdvdread`
  library.
* MKVToolNix GUI: multiplexer: when deriving languages from file names the GUI
  will now look for simplified language names instead of the full ones
  (e.g. instead of looking for "Greek, Modern (1453-)" it would simply look
  for "Greek").
* MKVToolNix GUI: multiplexer: the options in the "additional command-line
  options" dialog are now sorted alphabetically. Additionally the
  `--append-mode` option has been added as one of the only missing global
  options.
* MKVToolNix GUI: chapter editor: the chapter editor can now read chapters
  from DVDs if MKVToolNix has been build with the `libdvdread` library.
* MKVToolNix GUI: header editor: added an option in the preferences for
  displaying all date & time values in UTC instead of the local time
  zone.

Bug fixes

* all: fixed a crash when using the `MTX_LOGGER=file` syntax for logging debug
  messages without specifying a file name to log to. It will now log to a file
  called `mkvtoolnix-debug.log` in the system's default temporary directory,
  as initially intended.

Build system changes

* The [`libdvdread`](https://www.videolan.org/developers/libdvdnav.html)
  library will be used if found via `pkg-config`. If it is found, support for
  reading chapters from DVDs will be enabled in `mkvmerge` and the MKVToolNix
  GUI.
* Boost's Date/Time, Lexical Cast, Range, Range Adaptors, Tri-Bool, Variant
  libraries are not used anymore.
* MKVToolNix now requires a C++ compiler & standard library that support the
  following features of the C++17 standard: "`std::variant`", \ 
"`std::gcd`".
  For the GNU Compiler Collection (gcc) this means v7 or newer; for clang it
  means v4 or newer — the same versions required by earlier MKVToolNix
  versions.
* MKVToolNix now requires version 6.1.0 of fmtlib or later for the
  `fmt::to_string` function and bugfixes to the formatting of floating point
  numbers. If a system-wide version is installed that's older, the bundled
  copy will be used.
* The bundled version of fmtlib has been updated to release 6.2.1.

mkvtoolnix: updated to 46.0.0

Version 46.0.0 "No Deeper Escape"

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.
* 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.
* 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".

Bug fixes

* mkvmerge: Matroska reader: when regenerating UIDs for chapters mkvmerge will
  now fix referencing tag chapter UID targets to have the same values.
* 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.
* 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.
* mkvmerge: MPLS handling/MPEG TS reader: under certain circumstances mkvmerge
  copied one frame too many before switching to the next play item.
* 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).
* MKVToolNix GUI: fixed a crash that happened when closing the preferences
  after having closed at least one multiplexer tab.
* MKVToolNix GUI: macOS: changed the default of the "elide tab header \ 
labels"
  feature introduced in v45 from "no" to "yes" to mirror how \ 
versions before
  v45 behaved on macOS.

Log message:
mkvtoolnix: updated to 45.0.0

Version 45.0.0 "Heaven in Pennies"

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.
* MKVToolNix GUI: added an option in the preferences to disable all tooltips.
* MKVToolNix GUI: Windows: debug output sent via Qt's to Windows' debugging
  facility will use a more verbose message format including the application
  name, making it easier to filter for in SysInternal's "Debug View" \ 
utility.
* MKVToolNix GUI: multiplexer: if the file identification fails due to a JSON
  parser error, the output generated by `mkvmerge` will be output via Qt's
  debugging facility (viewable with SysInternal's "Debug View" utility on
  Windows; on other systems it's output on `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.
* MKVToolNix GUI: job queue: added an option in the preferences for removing
  completed jobs when exiting the program depending on their status.

Bug fixes

* mkvmerge: H.265/HEVC packetizer: fixed changing the NALU size length, it was
  using the wrong offset into the `hevcC` structure.
* mkvmerge: MP4 reader: fixed calculating the duration of video tracks that
  only contain a single frame.
* 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.
* mkvpropedit: Windows: mkvpropedit wasn't caching when reading the file to
  modify, slowing down operations such as adding track statistics tags
  considerably.
* 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 hyphens.
* 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 using the "show command line" menu \ 
option
  on Windows the path to the `mkvmerge` executable was shown with forward
  slashes instead of backslashes. This is a purely cosmetic fix as Windows
  supports both forward and backward slashes.
* 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).
* MKVToolNix GUI: multiplexer, info tool: fixed the "warn before \ 
overwriting"
  check wrt. jobs creating the same file.
