Just wanted to clear up two things:
1) it's not a lib. ;). It's a plugin. If you want to use it yourself,
copy the files, make it a loadable plugin in your system and provide
LGPL sources and patches. That's fully legal. Don't forget that the
sources require glib. There's a win32 version of glib, it's LGPL too.
You can also do a search'n'replace, we mostly only use types from glib
(gint instead of int, gchar instead of char, etc. - for portability
reasons), we don't use that many glib functions.
2) the things unimplemented are menus and metadata.
The code can be found in CVS, module gst-plugins, dir gst/matroska/.
