Atom feedMKVToolNix v97.0 released
2026-01-02 — mosu
Hi fine folks!
Happy new year everyone. Here’s v97.0 of MKVToolNix, probably the smallest release I’ve ever done with just two NEWS.md entries. But I like to keep up with my ususal schedule, so here we are. Feel free to skip this release if the feature mentioned below is irrelevant for you.
An important note for macOS users: I will stop providing macOS binaries and any kind of support for macOS in the second half of 2026 due to Apple discontinuing support for the Rosetta x86-to-ARM translation system. As my current build process only works on x86 (Intel) macs this will be the end of the line for any kind of mac support for me.
You can download the source code or one of the packages. The Windows packages as well as the Linux AppImage are available already. The other Linux packages & the macOS disk image are still being built and will be available over the course of the next couple of hours.
Here are the NEWS since the previous release:
Version 97.0 “You Don’t Have A Clue” 2026-01-02
New features and enhancements
- mkvmerge: MP4 reader: added support for TrueHD in MP4 with FourCC
mlpa. Implements #6178. - installer: the Windows installer will request admin permissions again, as it did before release 96.0.
Have fun 😁

Bug fixes
- mkvmerge: OBU reader: fixed probing files in which the first frame ends after the 1MB mark, which is how big the memory buffer used for probing content is. Fixes #6165.

.idxfiles that start with a byte-order mark (BOM) are now read again correctly. Fixes #6162. - mkvextract: AV1/IVF: fixed inserting a temporal delimiter OBU at the start of each frame if there is none. Mostly fixes #6120.
