Answer 1

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!

Answer 2

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

Answer 3

You might try asking this over at doom9 forums in their development section. Also mediainfo.dll might also work for you.

Answer 4

The simplest way to get a lot of this is to spawn an instance of mkvinfo and parse its output. One problem with what you are asking is that a Matroska file can have an unlimited number of video and audio streams. So you would have to enumerate the streams in the file prior to getting these properties.
