MKVToolNix 90.0.0
Version 90.0.0
Released Feb 8, 2025
Noteworthy changes / Bug fixes
## New features and enhancements
* MKVToolNix GUI: header editor: double-clicking on one of the three flag
indicators ("Default track", "Forced display", "Enabled") for a track in the
tree view will now toggle the corresponding flag. Implements #3773.
## Bug fixes
* mkvmerge: AAC parser: LOAS/LATM streams: fixed use of uninitialized data
when the `StreamMuxConfig` element doesn't contain the `audioMuxVersion`
element; version 0 must be assumed in such a case. The result was that
sometimes certain valid AAC packets were dropped. Fix by Stefan Pöschel.
* mkvmerge: HEVC/H.265 parser: fixed calculation of picture order count
calculation that was triggered under rare circumstances. Fixes #3775.
* mkvmerge: Matroska reader: enabled limits for how much data a single
Matroksa reader instance might buffer when the muxing core looks for packets
for specific tracks, avoiding huge memory consumption in cases where tracks
have huge gaps between packets. This might happen when appending files
containing forced-only subtitle tracks, for example. Fixes #3771.
* mkvmerge: TrueHD reader: increased the probe range for TrueHD sync frames
from 128 KB to 512 KB to avoid mis-detection with certain files with a lot
of data between sync frames. Fixes #3783.
* mkvmerge: MP4/QuickTime reader: fixed detection of Big Endian LPCM
audio. Fixes #3788.
## Build system changes
* The bundled `fmt` library was updated to v11.1.2.
* added a new option to `configure` called `--disable-dbus` to disable looking
for & using QtDBus even if it's present on the system. Default remains to
probe for its existence. Patch by Anthony Ryan.
# Version 89.0 "And the Melody Still Lingers On (Night in Tunisia)" 2024-12-27
## New features and enhancements
* mkvmerge: AC-3 writer: mkvmerge will now use the codec ID `A_AC3` even for
streams with bitstream IDs 9 or 10 instead of the deprecated codec IDs
`A_AC3/BSID9` & `A_AC3/BSID10`. Fixes #2387.
* MKVToolNix GUI: multiplexer: the mechanism for setting track languages to
specific values upon adding a file has gotten a new option to always set the
language, no matter whether or not the source container provided a track
language or what it was set to.
* all command-line tools: implemented an escape mechanism for when you want to
use the `@` sign as the first character in an argument to an option such as
`--title`. To escape it the `@` sign has to be doubled as in `--title
@@midnight`. Implements #3768.
## Bug fixes
* mkvmerge, mkvpropedit, MKVToolNix GUI's multiplexer & header editor: the
MIME type for TrueType & OpenType fonts will be set properly to either the
current MIME types `font/ttf` & `font/otf` or to the legacy MIME types
`application/x-truetype-font` & `application/vnd.ms-opentype` depending on
whether the "use legacy font MIME types" option is disabled or enabled, even
if the MIME database used by Qt returns the wrong one or even other MIME
types such as `application/x-font-ttf` & `application/x-font-otf`. This was
the case on Windows due to Qt 6.7.3 switching to a different embedded MIME
database. Partially fixes #3751.
* MKVToolNix GUI's multiplexer & header editor: ensured that both the legacy &
the current font MIME types are always present in the MIME type combo boxes
of attachments, no matter what Qt's MIME type database contains. Partially
fixes #3751.
* MKVToolNix GUI: the "disable tooltips" option in the preference will now
disable the tooltip for the status bar, too.
