    mkvtoolnix: updated to 82.0

    Version 82.0 "I'm The President" 2024-01-02

    New features and enhancements

    * mkvmerge: Matroska reader: the "video alpha mode" track header property will
     be copied to the output file if present.
    * mkvmerge: Matroska reader: the "video alpha mode" track header property will
     be reported in JSON identification mode as the track property
     `alpha_mode`.
    * mkvmerge: Matroska reader: the file's timestamp scaling factor will be
     reported in JSON identification mode as the container property
     `timestamp_scale`.
    * mkvmerge: MPEG transport stream reader: teletext subtitles intended for
     hearing impaired people (type 0x05) are now marked as such via the
     appropriate flag in the track headers.
    * mkvmerge: file identification: the JSON identification output schema version
     has been bumped to 19.
    * mkvmerge: added a new hack `always_write_block_add_ids` that can be used as
     a workaround for players that don't support the handling of missing "Block
     Addition ID" sub-elements of "Block More" elements in block additions
     properly. These are used for e.g. alpha channel data in VP9 with a "Block
     Addition ID" value of 1, which is also its default value.
    * mkvinfo: added support for the "video alpha mode" track header element.
    * mkvpropedit, MKVToolNix GUI's header editor: added support for the "video
     alpha mode" track header property. In `mkvpropedit` it's called
     `alpha-mode`.
    * MKVToolNix GUI: multiplexer: when adding files the GUI can automatically
     enable the "hearing impaired" flag for audio and subtitle tracks if the file
     name contains the word "cc" or "sdh" delimited by certain characters
     (configurable). This feature is turned on by default.
    * MKVToolNix GUI: multiplexer: when scanning for Blu-ray playlists the GUI
     will now ignore playlists that are likely meant for menus. Currently the GUI
     considers this to be the case when a playlist contains the same item at
     least five times. This behavior can be turned off in the
     preferences.

    Bug fixes

    * mkvmerge: MPEG transport stream reader: fixed a crash introduced in v81 that
     occurred when there was at least one PCM track that wasn't copied from the
     transport stream file.
    * mkvmerge: when reading data from Matroska files damaged in a specific way,
     mkvmerge ended up trying to write various types of elements that aren't
     allowed to be written (so-called `EbmlDummy` elements as well as elements
     that don't have a value set) to the output file, which caused the underlying
     `libebml` library to abort. These types of broken elements are now filtered
     out.

    Build system changes

    * Qt 5 is no longer supported. Qt 6 is now required for building
     MKVToolNix. This implies that the options to `configure` revolving around
     configuring Qt 5 or choosing between the two have been removed
     (e.g. `--disable-qt6`).
    * Qt 6 detection: if detection fails, error messages from `qmake` can now be
     found in `config.log`.
    * Qt 6 detection: `configure` will only consider Qt 6.2.0 or newer, not 6.0.x
     or 6.1.y anymore, due to the lack of support for the multimedia module.
    * Qt 6 detection: `configure` will now fail to detect Qt 6 if the 'multimedia'
     module is not found by `qmake` (e.g. due to development packages not being
     installed).
    * The bundled `fmt` library was updated to v10.1.1.
