Free and open-source Matroska software MKVToolNix v21.0.0 was released days ago. The biggest change is that mkvinfo’s GUI portion has been removed.
New features and enhancements in MKVToolNix 21.0.0:
- mkvmerge: track statistics tags: the
TagDefaultelement will not be written anymore as it was always set to the default value 1 anyway.
- mkvmerge, MKVToolNix GUI: JSON files can now contain C++-style line comments outside of strings (e.g. something like this:
// this is ignored). Such comments, even though not part of the official JSON specifications, are now ignored when reading JSON files.
- MKVToolNix GUI: chapter editor: opening a Matroska file without chapters in it will now open the file in an empty chapter editor instead of showing an error message.
- MKVToolNix GUI: an “info” tool has been added, replacing the functionality of mkvinfo’s GUI. The functionality is not on par yet but will be for release v22.
For the bug-fixes and other changes, see the release note.
