MKVToolNix for Mac

11 April 2021

Create, alter, and inspect Matroska (mkv) files.

What is MKVToolNix for Mac

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 MKVToolNix

Version 56.1.0:
New features and enhancements:
  • Mkvmerge: AAC: added support for LOAS/LATM files with channel configuration indexes 9-21 (e.g. channel count 22.2 for index 13) according to Rec. ITU-R BS.1196-7 & ISO/IEC 23008-3:2019.
Bug fixes:
  • Mkvmerge: HEVC/H.265 parser: fixed invalid memory access that could happen when reading certain types of HEVC data (e.g. with changing parameter sets mid-stream) from certain containers (e.g. Matroska). This bug was introduced in release 56.0.0. Fixes #3083.
  • Mkvextract: AAC: mkvextract will now abort with an useful error message when the user tries to extract a track whose 'audio-specific config' element in `CodecPrivate` signals a number of channels of 7 or greater than 8 as that isn't supported by the ADTS format.
  • Build system changes:
  • Configure: the `--enable-ubsan` option hasn't actually enabled anything since release 39.0.0.

Was it NECESSARY to drop down the support of High Sierra? On WHAT has 10.4 and 5 more 'power'? For all what I know, High Sierra is still now the best 'professional OS X'; later ones are 'gimmicky' iOS prone downgrades adding funky 'Gadgets' (Gadget is a name! Of the French company who built the statue of libery in front of the New York harbour!) of no-use by a serious 'power-user', in fact NOT supporting useful utilities like FinderPop, exempli gratia!) GRRRRRR!!!!!
