Matroska Muxer filter for DirectShow

I'm trying to create graph AudioCapture -> Vorbis Encoder -> Matroska Muxer, but graphedit inserts Vorbis Decoder before Matroska Muxer. I want th开发者_StackOverflow社区is graph working without Vorbis Decoder. How can I do this?

This means that the multiplexer you are using is unable to accept the Vorbis stream as a valid input. It can be one of the two:

• Something is wrong with media type, and it should be corrected so that both capture and mux accept it
• More likely - the multiplexer implementation has no sufficient support for Vorbis audio, and what you basically need to do is to replace it with the Vorbis-friendly alternative.
