MKVToolnix 70.0.0

MKVToolNix is the one of the best collection of tools (mkvmerge, mkvinfo, mkvextract, mkvpropedit and mmg) for modifying MKV files.

The graphical user interface (GUI) of the program allows you to manipulate Matroska (MKV) files in several ways.

You can use those tools to create, split, edit, mux, demux, merge, extract or inspect Matroska files.

MKVToolnix will also work with other video formats. Such as AVI, MPEG, MP4, MPEG, Ogg/OGM, RealVideo, MPEG1/2, H264/AVC, Dirac, VC1.

And more as well as some video codecs such as VP9 video codec support – reading from IVF, Matroska, WebM files, extract to IVF files.

Moreover the program can work with audio files such as AAC, FLAC, MP2, MP3, AC3, DTS/DTS-HD, Vorbis, RealAudio. And also work with most subtitle formats including SRT, PGS/ SUP, VobSub, ASS, and SSA.

It is a cross-platform application that will work on Microsoft Windows (both 32 and 64-bit versions), Apple macOS and Linux operating systems.

Here is also the portable version which does not require installation. You just need to start the function. It can also be stored on external devices and run on any computer you have access to.

# Version 70.0.0 “Caught A Lite Sneeze” 2022-08-14

## New features and enhancements

* MKVToolNix GUI: the user can now control where the job queue files & the
preferences INI file are stored via environment variables. If set, the
variable `MKVTOOLNIX_GUI_STATE_DIR` can point to a directory where the GUI
stores both the job queue sub-directory and the preferences INI file. If you
only want to relocate the preferences INI file, you can store the desired
file name for the INI file in `MKVTOOLNIX_GUI_CONFIG_FILE`. Implements
* MKVToolNix GUI: when adding directories via drag & drop/copy & paste the GUI
will now offer the user the option to create one multiplex settings tab per
directory & adding all files from that directory to the corresponding, newly
created tab. Implements #3371.

## Bug fixes

* mkvmerge: AV1 OBU parser: fixed identifying files that only contain single
frame. Fixes #3380.
* MKVToolNix GUI: multiplexer: when reading color parameters from identified
files that are floating point numbers (minimum/maximum luminance, projection
pitch/roll/yaw) the numbers will be formatted in floating-point notation
instead of scientific notation as mkvmerge only supports the former. Fixes
* MKVToolNix GUI: multiplexer: color parameters that are floating point
numbers (minimum/maximum luminance, projection pitch/roll/yaw) will only be
set to a value during identification if the identification actually contains
the property, and not to 0 anymore if it doesn’t.

## Build system changes

* Several merge requests where accepted that improve compilation on MSYS2 on
Windows. Note that this build type isn’t supported.
