Here is the caller graph for this function:

const char* FindMatchingElementName	(	const char *	srcCapsString,
		const char *	typeName
	)

Find an element name for an element that can produce caps compatible with 'srcCapsString' on its source pad, and has a klass name include 'typeName'. Returns NULL if none is found.

e.g. Call FindMatchingElementName("application/ogg", "Muxer") to get an ogg muxer element name ("oggmux" will be returned).
