Log Message:
mkvtoolnix: updated to 69.0.0

Version 69.0.0 "Day And Age" 2022-07-09

Important notes

* all: the spelling of "colour" was changed to "color" \ 
throughout all programs
  to match the use of American English spelling in MKVToolNix. This not only
  affects documentation and user interface controls, but also program options
  for mkvmerge & mkvpropedit. Both programs will continue to accept the
  British English spelling of their respective options indefinitely. One
  breaking change is that the property names in mkvmerge's JSON identification
  mode have also been changed to American English spelling. As those
  properties have only been introduced in release v68, this seems like a small
  enough window to make such a change.

New features and enhancements

* MKVToolNix GUI: the number of recently used entries (e.g. destination
  directories) remembered by the GUI can now be configured in the
  preferences.
* MKVToolNix GUI: multiplexer: when adding files the track properties
  regarding color information & color mastering meta information will be
  parsed & set in the corresponding GUI controls.
* MKVToolNix GUI: job queue: the job queue can now be sorted by clicking on
  the column headers.
* MKVToolNix GUI: job queue: when loading jobs from the queue directory that
  weren't previously known to the program those jobs will be sorted by their
  "date added" timestamp instead of using the order the operating system
  returns them in.

Bug fixes

* build system: fixed compilation with fmt v9.
* mkvmerge: HEVC ES parser: the parser will now parse at least the first full
  access unit before reporting that it has found all the required
  headers. Otherwise parsing might stop in the middle of the access unit due
  to the source reader not providing more data in the first call, leading to
  the parser not finding the `unspec62` and `unspec63` NALUs required for
  Dolby Vision.
* MKVToolNix GUI: preferences: the default actions added to the "execute
  programs" section on new installations now default to use WebM file names
  instead of Ogg, matching the format of the included audio files.

Build system changes

* The bundled `fmt` library was updated to v9.0.0.
