Heyooo.
Here’s the latest, the greatest (maybe?) release of MKVtoolNix, v96.0. Business as usual: couple of enhancements, couple of bug fixes.
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 96.0 “It’s My Life” 2025-11-08
New features and enhancements
- all programs: added a command-line parameter
--no-bomthat disables writing byte order marks to text files encoded with one of the UTF variants. Implements #6166. - MKVToolNix GUI: multiplexer: added variable
<MTX_CHAPTERS_FILE_NAME>to the “run program after job completion” mechanism containing the absolute path to the chapters file name. Implements #6172.
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.
- mkvmerge: VobSub reader: VobSub
.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.
- mkvextract: AV1/IVF: fixed a potential calculation error when deriving frame rate numerator & denominator from Matroska’s default duration. Part of the fix of #6120.
- mkvextract: AV1/IVF: fixed calculation of IVF frame number calculation from Matroska’s frame timestamps by rounding instead of truncating. Part of the fix of #6120.
Have fun 😁

Hey :)
Time for another release: a couple of new features/enhancements contributed by a kind person, a handful of bug fixes.
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:

- mkvmerge: PCM packetizer: mkvmerge will now always write frames with 40ms of samples, no matter how long or short the frames in the source files were. Part of the fix of #6149.

MKVToolNix v94.0 released
2025-07-27 — mosu
Hey y’all.
This is probably the smallest release I’ve ever done :) Just one bug fix & one feature. Apart from that a ton of work went into the macOS build scripts in order to be able to build universal binaries. It’s not finished yet, and therefore the work’s not part of the release.
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 94.0 “Initiate” 2025-07-27
New features and enhancements
- MKVToolNix GUI: multiplexer: the “delete source files after multiplexing” job runner will now delete both files of an
.idx/.subVobSub file pair. Implements #6133.
Bug fixes
- all: fix compilation without FLAC. Fixes #6128.
Have fun 😁
