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.

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!

Matroska Stem Files

This document defines a multi-track profile of the Matroska container format for storing stems for use by DJ applications while remaining backwards compatible with existing media players.

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.

What's a good #format to serialize simple structured #data in an efficient way?

I'm thinking about some binary #XML encoding. Also, #ASN.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?

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

One of the things that is interesting doing mass encodes is verifying all of the little things that can just mess everything up. If you're pulling in stuff like 3rd-party subtitles, then you have to verify the timing of the subtitles and adjust as necessary. Even better, if those are SubStation Alpha subtitles, you have to verify if the style fonts get added as attachments to the MKV file.

And if it's across something like a TV show, you definitely need to do this for every episode. If there _is_ an issue, you get to fire up Aegisub and try to track down the exact offset you'll need and either correct that via Aegisub or when you inevitably have to remux via `mkvmerge`/MkvToolnix.

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. https://www.bunkus.org/2026/01/2026-01-02-mkvtoolnix-v97-released/ #MKVToolNix #Matroska

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.
