Replace these with versions built using an older toolset (so as to avoid ABI compatibilities when linking on Ubuntu 14.04 for packaging purposes)

	/// It contains parameters of input, output and shared parameters. 
	/// Using the isSupported() method, the StreamParameters can be 
	/// checked if opening a Stream using this StreamParameters would 
	/// succeed or not. Accessors are provided to higher-level parameters 
	/// aswell as the lower-level parameters which are mainly intended for 
	/// internal use.
