mkvtoolnix: updated to 34.0.0

Version 34.0.0 "Sight and Seen":
Bug fixes
* mkvmerge: all subtitle frames are now treated as key frames in order to fix
  wrong data in source files.
* mkvmerge: AV1: fixed frame timestamp calculation when reading bitstreams
  that lack timing information from IVF files.
* mkvmerge: 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.

Log message:
mkvtoolnix: updated to 33.1.0

Version 33.1.0 "Primrose"

Bug fixes
* MKVToolNix GUI: multiplexer: Windows: using UNC paths
  (e.g. \\server\Videos) when the option "automatically set the destination
  file name" was set in the preferences, the GUI would create a destination
  file name with forward slashes (e.g. //server/Videos/outputfile.mkv), a
  syntax not supported by mkvmerge.
* build system: the programs were accidentally built without stack protection
  (-fstack-protector-strong) on recent versions of gcc and clang.

Version 33.0.0 "A Little Bit of Madness"

Bug fixes
* mkvinfo: when using the --size option, mkvinfo will now report the
  correctly if an element has an unknown size.
* MKVToolNix GUI: info tool: clusters with an unknown size will now be read
  and displayed correctly.
* MKVToolNix GUI: multiplexer: Windows: trying to open Blu-ray index or
  playlist files failed when the path to the files contained symbolic links
  (e.g. when mounting a drive in a sub-folder via Windows' disk management
  utility).
* MKVToolNix GUI: 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.
* MKVToolNix GUI: multiplexer: Windows: the GUI will let the user change the
  drive letter part of the destination file name freely again and only verify
  its validity right before starting to mux/adding to the job queue. Before it
  tried to force that into something valid, often resulting in unintentional
  paths (such as "C:\users\…\DC\files\…").

Log message:
mkvtoolnix: updated to 32.0.0

Version 32.0.0 "Astral Progressions":

New features and enhancements
* mkvinfo: when sizes are output the size of the element's data portion is
  output in addition to the element's total size.
* MKVToolNix GUI: info tool: the element's data portion is
  shown as an extra column.
* MKVToolNix GUI: multiplexer: added column "Delay" to the track list
  containing the additional delay to apply during multiplexing.

Bug fixes
* all: fixed handling of Unicode code points > U+FFFF.
* mkvmerge: Windows: mkvmerge was crashing with an exception when trying to
  identify certain files that can be used on Blu-rays (such as MPEG transport
  streams of MPLS play list files) and when the file name was given as a UNC
  path (e.g. `\\servername\sharename\path\to\file.m2ts`). The GUI emitted
  errors such as "the JSON output could not be parsed" in that case.
* MKVToolNix GUI: 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. Examples for when this is the case are
  Windows' "send to" or "open with" functions.
* MKVToolNix GUI: 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" setting.
* MKVToolNix GUI: 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.

Build system changes
* libEBML v1.3.7 and libMatroska 1.5.0 are now required as they fix their
  handling of Unicode code points > U+FFFF.

Log message:
mkvtoolnix: updated to 31.0.0

Version 31.0.0 "Dolores In A Shoestand":

New features and enhancements
* all programs: 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: when closing files that were opened for writing,
  cached data will not be flushed to storage automatically anymore. This
  reverts the workaround implemented for 2469. A new option was added to both
  programs (--flush-on-close) that re-enables flushing for people who are
  affected by data loss such as described in 2469.

  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.
* MKVToolNix GUI: multiplexer: the dialog previewing different character sets
  for text subtitles will now keep the position of the displayed text when
  switching between character sets.

Bug fixes
* mkvmerge: AVI reader: using DV type 1 AVIs will now result in an unsupported
  file type being reported (as the underlying AVI library doesn't support
  them) instead of crashing mkvmerge.
* mkvmerge: 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.
* mkvmerge: 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.
* mkvmerge: 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: multiplexer, chapter editor: fixed drag & drop handling with
  Qt 5.12.0 and newer.
* MKVToolNix GUI: multiplexer: the GUI did not clean up temporary files
  created when running mkvmerge.

Build system changes
* Qt 5.4.0 or newer has required (up from 5.3.0) since version 30.0.0; I just
  forgot to include this entry.

Log message:
mkvtoolnix: updated to 30.1.0

Version 30.1.0 "Forever And More":

Bug fixes
* build system: fixed building on non-UTF-8 locales.
* MKVToolNix GUI: multiplexer: implemented a workaround for drag & drop not
  working on macOS with Qt 5.12 due to a bug in Qt 5.12.
* MKVToolNix GUI: 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.

Log message:
mkvtoolnix: updated to 30.0.0

Version 30.0.0 "Interstellar"

New features and enhancements
* mkvextract: 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.
* MKVToolNix GUI: 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.
* MKVToolNix GUI: multiplexer (preferences): 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.
* MKVToolNix GUI: multiplexer (preferences): the predefined split sizes and
  durations can now be customized in the preferences.
* MKVToolNix GUI: chapter editor: added an option in the "Chapter \ 
editor" menu
  for appending chapters from an existing file to the currently open editor
  tab.
* MKVToolNix GUI: chapter editor: added an action in the context menu for
  copying the selected entry and all of its children to another open editor
  tab.

Bug fixes
* mkvmerge: 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.
* mkvmerge: AAC: under certain conditions 8 channel audio files were taken for
  7 channel ones.
* MKVToolNix GUI: multiplexer: removing a file added as an "additional \ 
part"
  will no longer cause a crash.
* source code: fixed compilation with Boost 1.69.0 after API-breaking change
  to the `boost::tribool` class.
