MKVToolNix overview

MKVtoolnix is a set of tools to create, alter, and inspect Matroska files under OS X, Linux and other Unices, and Windows. They do for Matroska what the OGMtools do for the OGM format and then some.

Since May 1st 2003, the Matroska libraries themselves and my Matroska tools are officially released as a first public beta version. Although all of them are still under heavy development, I urge you to download the software, test it and report any errors you encounter to me. I'm always grateful for good bug reports because I miss so many mistakes and you guys normally find them. Your feedback is important to me :)

Note: While the software is classified as free, it is actually donationware. Please consider making a donation to help support development.

What’s new in version 85.0

Bug fixes
  • Fixed compilation of `src/common/sorting.h` with certain compilers due to the deprecation & removal of `std::result_of<>` in C++20. Fixes #3695.
  • Fixed compilation with the `gtest` library when `gtest` requires additional libraries by querying `pkg-config` for the correct flags & libraries to build with. See #3696.
  • MKVToolNix GUI: multiplexer: restored the keyboard shortcut for switching to the "Attachments" tab (Alt+C for the English interface). Fixes #3702.
  • MKVToolNix GUI: multiplexer: fixed several cases when the keyboard shortcuts for copying the first source file's name/the destination file's name to the title (Ctrl+F & Ctrl+D) and the one for copying the title to the destination file name (Ctrl+T) were not enabled. Fixes #3705.

Seems many people didn't know. If you mac won't open the file, just hold down 'control' while clicking the app, then choose 'open'. it will then always open.
