As you probably know, we have released today a stable DirectShow parser 
to read matroska files. It can be found on 

There is also a TCMP plugin to retrieve more infos about a matroska 
file. And also new sources with additions and some bug corrections (on 
reading and writing).

The next steps I can see in the near future :
- DS: add a properties dialog box to retrieve informations from the 
matroska file, and maybe inspect the queues

- DS: make a non UNICODE version for Win98 ?

- libmatroska: change ProcessMandatory so that mandatory elements that 
are not unique are at least added once. Writing applications may need a 
few modifications (fill this first element before adding new ones to the 

Then we can work on the more important things. The DirectShow filter 
being in the center (and muxing apps when new features are added), like 
moving to an ASync reader (which is already the case but not in the DS 
terms) and being able to select the audio/video/subtitles tracks.
