MKVCleaver!

MKVToolnix is a set of tools to create, alter and inspect Matroska files under Linux, other Unices and Windows. They do for Matroska what the OGMtools do for the OGM format and then some. The latest builds now have the ability to create WebM compliant Files.

This is a GUI frontend for mkvextract from MKVToolnix. It will extract the tracks of a Matroska video and audio files.
