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.
