MKVToolNix v40.0.0 released

2019-11-09 — mosu

Hey y’all,

there’s been quite a lot of feedback on the changes in v39, and due to it I decided to make two of the new features configurable: the dark mode for Windows & deriving the file name from the file title. Combine that with an easy-to-trigger regression in the MP4 handling in v39, and I’ve decided to get a new release out sooner rather than later. So here it is, v40.0.0 is out.

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

• mkvmerge: MP4 reader: added support for BMP covert art images.
• MKVToolNix GUI: multiplexer: added an option to disable deriving the
  destination file name from the file title. Implements #2648.
• MKVToolNix GUI: multiplexer: the content of the “stereoscopy” combo box has
  been simplified making the box’s minimum width much smaller, allowing the
  user to resize the GUI’s whole window to a much smaller width.
• MKVToolNix GUI: multiplexer: whenever the user changes the “aspect ratio” or
  “display dimensions” controls, the corresponding radio button will be
  activated automatically. Implements #2651.
• MKVToolNix GUI: Windows: added a setting in the preferences to disable the
  GUI’s dark color mode even if Windows’s app color mode is set to
  dark. Implements #2646.
• MKVToolNix GUI: Windows: replaced the dark mode introduced in v39 with
  another dark mode that’s less wasteful with space between widgets.

Bug fixes

• mkvmerge: MP4 reader: mkvmerge was reading eight bytes too many for cover
  art images. This could cause file identification to fail when the cover art
  was located at the end of the MP4 file. Even if it succeeded, this meant too
  much data present in the attachment. Fixes #2650.
• mkvmerge: MP4 reader: covert art images with unknown image types will be
  skipped instead of treated as JPEG images.

Build system changes

• Qt 5.9.0 or newer is now required for building MKVToolNix GUI.

Have fun :)
