Heyo 💝

MKVToolNix v86.0 is out. There were several bug fixes, most notably around the handling of timestamp files. That was code I hadn’t touched for… a decade, maybe. Quite the trip. A couple of enhancements were also made; see below.

You can download the source code or one of the packages. The Windows packages and macOS disk image as well as the Linux AppImage are available already. The other Linux packages are still being built and will be available over the course of the next couple of hours.

Here are the NEWS since the previous release:

New features and enhancements

• mkvmerge: Matroska reader: track statistics tags are included in the JSON identification output just like other tags had already been included: as part of the track properties, prefixed with tag_. Implements #3714.
• mkvmerge: MPEG TS reader: mkvmerge will now detect teletext subtitle tracks even if they’re not listed in the PMT as long as it can find teletext pages flagged as subtitles in the header within the probed ranged of the file. Implements #3650.
• MKVToolNix GUI: multiplexer: the default mode for escaping the arguments in the “Show command line” dialog can now be set in the preferences. Partially implements #3709.
• MKVToolNix GUI: multiplexer: the “Show command line” dialog now includes the command lines for all currently open multiplex settings, switchable with a combo box. Partially implements #3709.
• MKVToolNix GUI: multiplexer: some users add the option --regenerate-track-uids to the “additional options”, even though --regenerate-track-uids is a file-specific option, and you can only use global options in the “additional options”. However, the GUI currently doesn’t have an option for specifying additional file-specific options. The GUI now detects the use of this option in the “additional options” & adds it for each of the source files instead. Implements #3707.
• MKVToolNix GUI: multiplexer: the option --regenerate-track-uids has been added to the “additional command line options” dialog. See #3703.
• translations: added a Norwegian Bokmål translation of the man pages by Roger Knutsen (see AUTHORS).

Bug fixes

• mkvmerge: when using timestamp files for subtitle tracks, mkvmerge will no longer set a default duration for the track. Partially fixes #3711.
• mkvmerge: when using timestamp files for subtitle tracks, mkvmerge will no longer queue frames longer than necessary, which resulted in the frames sometimes being written much later than they should have been according to their timestamps. Partially fixes #3711.
• mkvmerge: when using timestamp files for subtitle tracks, mkvmerge will now write the packets’ duration properly. Partially fixes #3711.
• MKVToolNix GUI: job queue: the shortcut from the “Job queue” menu are now enabled correctly whenever the number of jobs in the queue changes (e.g. by adding new jobs). Fixes #3720.

Have fun 😁
