MKVToolNix 14.0.0 Released with New Features and Bug Fixes

MKVToolNix 14.0.0, a new release of the free and open source Matroska libraries and tools, was release a day ago with new features, enhancements, and various bug-fixes.

New features and enhancements in MKVToolNix 14.0.0:

• mkvmerge: AAC: implemented support for AAC with 960 samples per frame.
• mkvmerge: identification: if the encoding/character set of a text subtitle track is known (e.g. because a byte order mark is present in the file), then it will be output during identification as the encoding property.
• mkvmerge: WAV reader: added support for Wave64 files.
• mkvmerge, mkvpropedit, MKVToolNix GUI (chapter editor): added support for chapters in WebM files that is spec-compliant by removing all tag elements not supported by the WebM spec.
• mkvpropedit: added support for tags in WebM files that is spec-compliant by removing all tag elements not supported by the WebM spec.
• MKVToolNix GUI: multiplexer: if the encoding/character set of a subtitle track cannot be changed, the GUI will deactivate the “subtitle character set” drop-down box and ignore changes to it when multiple tracks are selected. Additionally, if the track’s encoding is known and cannot be changed (e.g. due to a byte order mark in the file), that encoding will be selected in the drop-down box automatically. Both changes signal to the user that she doesn’t have to take care of the encoding herself.
• MKVToolNix GUI: chapter editor: added a function to the “additional modifications” dialog for calculating and setting the end timestamps.
• MKVToolNix GUI: changed the shortcuts for switching between the various tools from Alt+number (e.g. Alt+1 for the multiplexer tool) to Ctrl+Alt+number in order to avoid clashing with Windows’ input method for arbitrary characters (pressing and holding Alt and typing the codepoint on the number pad).
• MKVToolNix GUI: added a “Window” menu and entries with shortcuts for selecting the next (Ctrl+F6) respectively previous tab (Ctrl+Shift+F6) in the current tool.
• MKVToolNix GUI: on Windows the GUI will now determine the default font to use by querying Windows for the default UI/message box font instead of using the hardcoded Segoe UI.

The new release also adds a Romanian translation, and fixes various bugs. See the release note for details.
