MKVToolNix v64.0.0 released

Hey everyone.

Hope y’all are having a couple of stress-free days behind & ahead of you, whatever you might or might not celebrate. I still haven’t had much energy to invest into coding, to be honest, but decided to do one last release in 2021 anyway, mostly fixing a couple of smaller issues — especially the wrong-sized icons on high DPI displays, which I’ve gotten so many bug reports about 😁

You can download the source code or one of the binaries. The Windows and macOS binaries as well as the Linux AppImage are available already. The other Linux binaries are stil 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

  • MKVToolNix GUI: language dialog: when the user switches between the two edit modes, the mode’s corresponding first control is automatically focussed.

Bug fixes

  • all: language lists: the entries for “Ancient Greek (to 1453)” and “Modern Greek (1453-)” have been renamed to “Greek (ancient, -1453)” and “Greek (modern, 1453-)” respectively in order to be easier to find.
  • mkvmerge: VobSub reader: files containing id: -- lines to indicate that the track language isn’t known were rejected by mkvmerge. Now they’re accepted, and und (undetermined) is used as the language. Fixes #3246.
  • MKVToolNix GUI: chapter editor: the “Save to Matroska or WebM file” function was using the wrong standard file dialog (the “open file” one instead of “save”), leading to confusing button names. Fixes #3242.
  • MKVToolNix GUI: high DPI scaling: fixed the icons in the tool selector having the wrong size for scaling factors other than 100% or 200%. Fixes #3229.

Build system changes

  • The bundled fmt library was updated to v8.0.1.
  • The bundled nlohmann-json library was updated to v3.9.1.
  • The bundled pugixml library was updated to v1.11 revision 6a76cac.
  • The bundled utf8-cpp library was updated to v3.2 revision b85efd6.

Have fun 😁
