SolveigMM MKV Muxer filter
The MKV/WEBM muxer filter implemented as a DirectShow filter. It's purpouse is to multiplex input video/audo/subtitles into Matroska or WEB Matroska containers.

Features
The filter supports MKV and WEBM as an output formats.
The filter's property page is a table shown on fig. 1. It includes the following control elements:
- DocType - output stream type (matroska or webm).
- A set of properties for each input stream(including Track's name and language and also enabling/disabling current track).
Usage
NOTE: All changes must be applied (using either APPLY button in Graph Editor or Apply method of IPropertyPage interface) to take place, the default values are used otherwise.
To use the filter manually:
- Add filter to a graph.
- Build the graph.
- Set desired properties for each input streams and the type of output stream.
- Run the graph.
To use programmatically not using property page:
The following section describes the Parameter GUIDs declared in the PropID_MatroskaMuxer.h header file to be used for tuning the SolveigMM Matroska Muxer Filter by means of the IModuleConfig interface.
