Introduction It’s not often you see so many logos of tech giants on one page backing the same technology. In my experience, every enterprise has developed a case of NIH and come up with their standards. No surprise then that there’s an XKCD describing this phenomenon! But when the AV1...

Matroska is a multimedia container widely know for it's video format (mkv). Lesser known are the audio (mka) and subtitles (mks) formats. Also the stereoscopic/3D format (mk3d). Aside from being open and royalty-free, why are these formats interesting?
Tools
MKVToolNix is a CLI (optional GUI) tool to work with Matroska files. It works with mkv and mka, which are the two formats I tested. It's a single tool to work with both audio and video formats.
Features
Matroska is a do-it-all "universal" container that does many things well. The most interesting being:
- Chapters. For an audio file that means an entire album or audiobook can be contained in a single large mka file splitted by chapters, similar to m4b files. It's easy to make such a file in mkvtoolnix, would save me a lot of time from picking every ogg chapter file in librivox recordings.
- Multiple streams. A single file can hold different codecs (e.g. vorbis, opus and MP3) or different bitrates and they can be muxed from a supported player. Video players commonly support it whereas I am not aware of audio players with this feature.
- Subtitle embedding. Closed captions are popular in mkv, but mka could also hold an entire timestamped audiobook or music lyrics inside. Haven't tested it though, and I think there's no player that supports such scheme.

So, what about MKS?
I couldn't find documentation about it, or even sample files. Maybe you can help.

I am looking for a website similar to Privacytools, Prism Break, Ethical.net or switching.software but more focused on freedom than privacy, presenting the best replacements for proprietary programs in the desktop and mobile. Is there anything like that?
