# 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. Part of the implementation of
#3643.
* mkvmerge: Matroska reader: the “video alpha mode” track header property will
be reported in JSON identification mode as the track property
`alpha_mode`. Part of the implementation of #3643.
* 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. Workaround for the
player issues listed in #3643.
* mkvinfo: added support for the “video alpha mode” track header element. Part
of the implementation of #3643.
* mkvpropedit, MKVToolNix GUI’s header editor: added support for the “video
alpha mode” track header property. In `mkvpropedit` it’s called
`alpha-mode`. Part of the implementation of #3643.
* 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. Implements #3648.
* 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. Implements #3658.

## 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. Fixes #3645.
* 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`. See #3649.
* 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). See #3649.
* The bundled `fmt` library was updated to v10.1.1.
