mkvtoolnix: updated to 74.0.0

Version 74.0.0 "You Oughta Know" 2023-02-12

New features and enhancements

* mkvmerge: SRT handling: added a hack called `--engage
  keep_whitespaces_in_text_subtitles` which disables stripping whitespaces
  from the start & end of each line of SRT entries during muxing.

Bug fixes

* all: Windows: UNC paths of type `\\?\C:\…` are supported again by switching
  back to Boost's file system library instead of using C++17's file system
  library.
* mkvmerge: AVC/H.264 & HEVC/H.265 packetizers: when appending tracks the
  pixel dimensions will be checked & muxing will be aborted if they don't
  match.
* mkvmerge: file type detection: file types that can be detected unambiguously
  by their content (e.g. Matroska, MP4, WAV…) will now preferred in the
  detection order over file types based on their extension. Prevents certain
  cases of mis-detection, e.g. DTS in WAV but with a file name extension of
  `.dts` being detected as the wrong type of DTS.
* mkvmerge: SRT handling: whitespaces will now be stripped from the start &
  the end of each line of each entry, not just from the end of the last
  line.
* mkvextract: SRT extraction: whitespaces will not be stripped from the start
  & end of the whole entry anymore.
* MKVToolNix GUI: multiplexer: when adding multiple files that include certain
  file types (chapters, segment info and tag files) and when the choice where
  to add them is "all files to a single new tab", these certain file types
  will now be added in the newly added tab as well instead of the current tab
  that had already been open.
* build system: fixed compatibility with Ruby 3.2.0 by using `FileTest.exist?`
  instead of `File.exists?`, `Dir.exists?` & `FileTest.exists?` which were
  removed in that release.

Build system changes

* MKVToolNix is now using & requiring Boost's "file system" and \ 
"system"
  libraries again instead of C++17's file system library. This is due to gcc's
  library not supporting UNC paths of types `\\?\C:\dir\file.ext`.

mkvtoolnix: updated to 73.0.0

Version 73.0.0 "25 or 6 to 4" 2023-01-02

New features and enhancements

* mkvmerge: greatly enhanced the speed of Base64 decoding which is used used
  e.g. when reading pictures embedded in Ogg or FLAC files or for binary data
  inside XML chapter & tag files. Even small blocks of data could take
  unreasonably long.
* mkvmerge: added support for reading HEVC/H.265 video from FLV
  containers.

Bug fixes

* mkvmerge: splitting: fixed a typo in the string output in GUI mode regarding
  the timestamps before which splitting was done.
* MKVToolNix GUI: job output: after having run multiple jobs the "Clear
  output" functionality only reset the visible parts. However, using the \ 
"save
  output" function would also save the output generated before the user used
  "clear output". Now only the output after the last use of \ 
"clear output" is
  saved.
* build system: when probing for the FLAC library the Ogg libraries will be
  linked with the compiled test program as well. This fixes detection if the
  `pkg-config` settings for FLAC don't list Ogg & the linker doesn't find the
  library automatically (e.g. for my macOS builds).

mkvtoolnix: updated to 72.0.0

Version 72.0.0 "Minuano (Six-eight)" 2022-11-13

New features and enhancements

* mkvmerge: AV1 parser: the variable-width OBU size field will be re-written
  with minimal length if it's encoded longer than necessary.
* mkvmerge: when splitting is active the program will output the timestamps
  actually used for making the decision when to split. If GUI mode is active,
  a specially formatted line `#GUI#splitting_before_timestamp <timestamp>` is
  output as well. Lines prefixed with`#GUI#` are suitable for machine parsing,
  won't be translated and are guaranteed not to change in format.
* MKVToolNix GUI: multiplexer: when dragging & dropping directories to the
  "attachments" tab, the files contained in those directories will be
  attached.
* MKVToolNix GUI: info tool: added information about the file (directory,
  size, modification timestamp) at the top of each tab.

Bug fixes

* mkvmerge: AV1 parser: fixed the parser completely aborting when parsing the
  OBU size field fails due to there not being enough data to parse. Instead
  the parser will remember the last known-good position & restart from there
  after more data is available.
* mkvmerge: HDMV PGS subtitles: reverted the change that implemented a
  heuristic for detecting bogus timestamps & attempting to fix them. This was
  done to fix 3268. Unfortunately this affected valid subtitle files with
  intentional huge gaps in timestamps, e.g. forced subtitle tracks. The
  heuristic has simply been removed, fixing 3392.
* mkvmerge: Matroska reader: fixed reading files with EBML Void elements
  before the Matroska Segment element.
* mkvmerge: fixed reversed attachment selection: `--attachments !4` would not
  copy any attachment instead of all attachments but the one with ID 4.
* mkvextract: IETF BCP 47/RFC 5646 language tags: mkvextract will now use &
  prefer IETF BCP 47 track language elements if they're present. Only affects
  the VobSub & USF subtitle extraction.
* mkvpropedit, MKVToolNix GUI's chapter & header editors: updated the list of
  deprecated Matroska elements. The applications will no longer try to write
  those elements, even if they're found in the file to be modified. The
  programs will no longer abort with error messages such as `assertion \ 
"false"
  failed`.
* mkvpropedit, MKVToolNix GUI's chapter & header editors: when the Matroska
  version numbers stored in the EBML Head element are updated, the updated
  EBML Head element might be smaller than the existing one. In that case the
  programs used to shrink the EBML Head & write a small EBML Void element
  between the updated EBML Head & the following element, usually a Matroska
  Segment element. This isn't widely supported by programs including
  MKVToolNix itself, causing them to declare such files as invalid. The
  programs will now create the EBML Void element inside the EBML Head element,
  making them a level 1 element instead of a level 0 element.
* mkvpropedit, MKVToolNix GUI's chapter & header editors: often the programs
  have to relocate the Master elements in which the modifications were
  done. In that case the Seek Head elements must also be updated to reflect to
  the Master elements' new positions. If a file contained a Seek Head element
  at the start already and if that Seek Head was too small to contain the
  updated positions, the programs would end up in an endless loop trying to
  write data to the end, creating ever-growing files. This is now handled
  properly by voiding this too-small Seek Head & finding a proper space for a
  new one instead.
* MKVToolNix GUI: header editor: fixed pixelated icons on higher display
  scaling values.

Build system changes

* bug fix: libFLAC detection is now done via `pkg-config`, and the
  corresponding compiler flags are honored. Fixes static compilation with
  newer versions of libFLAC with MXE where a compiler definition is required
  to signal that it libFLAC wasn't built as a DLL.

Log message:
mkvtoolnix: updated to 71.1.0

Version 71.1.0 "Fortitude" 2022-10-09

Bug fixes

* Chapters DTD: added the new edition & chapter elements from Matroska v5.
* Chapters DTD: fixed EditionUID being mandatory. mkvmerge can auto-generate
  it if it's missing from the XML file.
* Chapters DTD: fixed the `example-chapters-1.xml` not validating against the
  DTD.
* Chapters DTD: corrected the old name `EditionManaged` to
  `EditionFlagOrdered`.
* Chapters DTD: fixed `ChapLanguageIETF` missing its element declaration &
  `ChapterLanguage` being required.
* XML DTDs: fixed elements representing binary data not allowing the `format`
  attribute.

Build system changes

* bug fix: configure accidentally tested for libEBML ≥ 2.0.0 & libMatroska ≥
  2.0.0, even though the actual requirements are 1.4.4 & 1.7.1 respectively.

Version 71.0.0 "Altitude" 2022-10-08

New features and enhancements

* mkvmerge, MKVToolNix GUI's multiplexer: added support for the Emphasis audio
  track header element via the `--audio-emphasis` option. It is also read from
  Matroska files.
* mkvmerge: the options `--list-stereo-modes` and `--list-audio-emphasis` have
  been added to list all support numerical & textual values for the
  `--stereo-mode` & `--audio-emphasis` options.
* mkvpropedit, MKVToolNix GUI's header editor: added support for the Emphasis
  audio track header element via the `emphasis` property.
* MKVToolNix GUI: multiplexer: when the track properties are
  configured to be displayed in a tab widget below the files & tracks
  in the "Input" tab, the "Color information" tab will be \ 
laid out in
  two columns. This reduces the minimum height the whole tab widget
  requires.
* MKVToolNix GUI: greatly sped up closing the preferences dialog by only
  re-running certain initialization functions when their corresponding
  settings have changed.
* mkvinfo, MKVToolNix GUI's info tool: added support for the following new
  elements from Matroska v5: Emphasis audio track header element; Chapter Skip
  Type; Edition Display; Edition String; Edition Language IETF.
* mkvmerge, mkvpropedit: added support for the following new chapter elements
  from Matroska v5: Chapter Skip Type; Edition Display; Edition String;
  Edition Language IETF. The GUI's chapter editor will receive support for
  them in the next release.

Bug fixes

* mkvmerge: Ogg/OGM reader: mkvmerge will now correctly skip tracks of
  unsupported types as well as tracks for which all track header pages
  haven't been found.

Build system changes

* libEBML 1.4.4 & libMatroska 1.7.1 are now required.
* The bundled libEBML & libMatroska libraries were updated to v1.4.4 & v1.7.1
  respectively.
* The bundled `fmt` library was updated to v9.1.0.
* The bundled `nlohmann-json` library was updated to v3.11.2.
