Does MKV have metadata?

MKV metadata is the data information about the MKV file – including the title, artist, creation date, genera, album name, encoded date, and more. It makes the MKV files easier for viewers, search engines, and software to understand and organize.

There is always attempting to parse the header yourself.

Also I've seen references to the EBML library being used to decode MKV files. Good luck!

I recently posted C# version to https://github.com/OlegZee/nebml. It contains Title editor sample which demostrate inline editing of certain properties.
