  1. Alrighty, let's do another MKVToolNix release, v98.0 this time. Again, pretty small in scope, but then again there's no use in not doing a release, so why not? 😂 Have fun! bunkus.org/2026/04/2026-04-05- #MKVToolNix #Matroska

  2. The long test is looking good for the `av1an`, `mkvmerge`, and `cleanup` modules, the Golang client is doing exactly what its supposed to which is a welcome change from yesterday. I need to do long tests on the `ffmpeg` and `handbrake` modules next, but I'll handle those tomorrow.

    After that, I'll update documentation, release the `2.0.0` client, and deprecate the old client.

  3. Okay, spammed* as many audio related forums and mailing lists as I could think of where I actually use their stuff or where there might be general interest about my musical stems file format for DJing and tracks meant for re-mixing. It's such a niche thing that I have received very little feedback so far, but if you can think of anyplace that might be open to providing feedback (ie. DJ applications like Mixxx or DAWs like Ardour who might want to implement the format in the future), let me know so I can ask if they're willing!

    * With a relevant ask for help from potentially interested stakeholders.

  4. I've just released Mp3tag for Mac v1.12 🌱

    • Download via mp3tag.app/get
    • Release Notes at community.mp3tag.de/t/mp3tag-f

    Mp3tag is a powerful and easy-to-use tool to edit metadata of audio files. Musicians, DJs, podcasters, and audio-enthusiasts use it for many different aspects of handling audio files.

    Enjoy and take care 🧡

  5. Ah previous me...I see you've decided to make this rewrite more difficult because you got _clever_ and I decided to keep backward compatibility. Thought that the `ffmpeg` module would be the biggest pain in the ass, but I was completely wrong. The `mkvmerge` part is coming along and I'm hoping to have it done today or tomorrow. Things progress.

  6. What's a good to serialize simple structured in an efficient way?

    I'm thinking about some binary encoding. Also, .1 because it natively uses integers, not just strings. Is the packed representation (PER) widely supported?

    The data will be a bunch of interleaved time series streams, so variable field lengths could be a big win.

    Is there a format for stuff like that?

    's EBML? Only I'd have to hack the schema in.

  11. The smallest release of MKVToolNix ever is out, v97, with just one change. But still, have to keep up with the schedule, I guess 😁 Note to macOS users: I've decided to stop offering macOS binaries in the second half of 2026 due to Apple sunsetting support for the Rosetta x86-to-ARM translation technology and my build process only producing x86 binaries. bunkus.org/2026/01/2026-01-02- #MKVToolNix #Matroska

  13. Free Software that I rely on. One per day.

    Day 18:

    MKVToolNix

    This is a tool kit of utilities, including a GUI front end, for manipulating Matroska streaming multimedia files (usually "MKV" or "MKA" files).

    The Matroska container format allows for multiple audio, video, and text streams, which means you can encode a video with multiple options for audio and subtitles (as well as alternate video tracks).

    It also supports setting up "Chapter" marks.

    A must-have for authoring and checking complex videos for streaming and download use.

  14. Let's do another release of MKVToolNix today, v96.0. This is another of those small maintenance releases with a couple of enhancements & a couple of bug fixes. Have fun! 😁 bunkus.org/2025/11/2025-11-08- #MKVToolNix #Matroska

  15. The idea behind this new format is simple: what if we returned to the older AUP format, but we put everything in a binary #XML representation? After all, an #AUP project is just an XML file with a directory containing block files, so why not merge all this data in a binary XML representation?

    It turns out we can, and what better format to use than #EBML? #Matroska uses it, and since it's a container that supports audio, we can use it as a starting point for our new project format.

  16. Hey 😁 Time for release v95 of MKVToolNix: a couple of new features/enhancements contributed by a kind person, a handful of bug fixes. Have fun! mkvtoolnix.download #MKVToolNix #Matroska

  17. Firefox tukee nyt Matroska-videoformaattia

    Pyyntö Matroskan (eli MKV:n) tuen lisäämiseksi Firefoxiin tehtiin jo 8 vuotta sitten, mutta nyt se - vihdoin - on saatu mukaan Firefoxiin.

  18. Small thing I noticed today: splitting `.mkv` files using `ffmpeg` via the `-ss` and `-t` options works great, but the resulting `.mkv` file contains the wrong number of frames in the metadata. Evidently the total frames from the source file gets written into the metadata instead of the resulting frames post-splitting which is annoying. Not a deal breaker, but kind of annoying...easy to fix with a quick run through `mkvmerge` but still just weird.

  19. 2/3

    A little more reading of some non-AI internet had me try just changing the file type suffix from webm to mkv.
    That's #Matroska, #MKV - a container.

    And the video (only) plays on the #SamsungTV base model code #JU6400.
    And the TV tells me the audio format ( .opus) is not supported.

    But #FFMPeg made short work of transcoding audio. Under 3 minutes instead of hours. Went to aac. Still renaming the webm file to a .mkv container.

  20. A new MKVToolNix release is out, v92, with a handful of bug fixes & enhancements. Nothing major. Have fun! :grin: bunkus.org/2025/04/2025-04-26-

  21. MKVToolNix v91 is out with a lot of enhancements to the GUI & bug fixes in other components. Get it while it's hot! bunkus.org/2025/03/2025-03-16-

  22. A new MKVToolNix is out right now, v90. Couple of bug fixes, one nice enhancement for header editor users. Have fun! bunkus.org/2025/02/2025-02-08-

  23. End of year? Time for a last release of MKVToolNix: v89 is out. A handful of fixes & enhancements, nothing too crazy. Is it good for you? You bet! bunkus.org/2024/12/2024-12-27-

  24. yay, a new MKVToolNix v88 is out 🥳 Not really a lot of changes, but we have to keep the party going, I guess! bunkus.org/2024/10/mkvtoolnix-

  25. A new MKVToolNix is out, version 87.0. Not a lot happening, couple of small fixes, couple enhancements. Enjoy! bunkus.org/blog/2024/09/mkvtoo

  33. I've just released MKVToolNix v86. You know the drill: a couple of enhancements, a handful of bug fixes, have fun updating. bunkus.org/blog/2024/07/mkvtoo

  34. Just released MKVToolNix v85! bunkus.org/blog/2024/06/mkvtoo Not a lot going on here, just a tiny number of bug fixes. Enjoy!
