14 DAY TRIAL // MKVToolNix developer Moritz Bunkus has released this weekend a new major version of his wildly used, cross-platform, and open-source MKV (Matroska) manipulation software.
According to the release notes, MKVToolNix 9.1.0 is yet another major release of the acclaimed software project, bringing numerous improvements to the main components, such as mkvmerge and mkvextract, but also to the MKVToolNix GUI (Graphical User Interface).
Probably the most important change is a patch for a bug that could lead to MKVToolNix using more than 2 GB or RAM when attempting to load stored settings form JSON files. The patch is nothing more than an update to the JSON library, as explained by the developer in the official release announcement.
"Here’s another release of MKVToolNix. Several bugs have been fixed. A rather important one is an update to the JSON library used which fixes immense memory consumption when loading stored settings (e.g. a ~500 KB JSON file leading to consumption of more than 2 GB of memory)," said Moritz Bunkus.
Here's what's new in MKVToolNix 9.1.0
Prominent features of MKVToolNix 9.1.0 include initial support for WebVTT subtitles, better support for teletext subtitles in MPEG transport streams, the addition of multiple fields in the JSON/verbose identification formats, as well as better support for handling AVC/h.264 interlaced frames that have the bottom field first.
Also new in MKVToolNix 9.1.0 is an option in the Merge -> Output preferences to control if the GUI should clear the "output file name" input when the user removes the last file, along with an option in the Merge -> Default values preferences to control if the GUI should clear the "file title" input when deleting the last file.
