Function Documentation

OMX_ERRORTYPE base_video_port_Constructor	(	OMX_COMPONENTTYPE *	openmaxStandComp,
		omx_base_PortType **	openmaxStandPort,
		OMX_U32	nPortIndex,
		OMX_BOOL	isInput
	)

The base contructor for the generic OpenMAX ST Video port.

This function is executed by the component that uses a port. The parameter contains the info about the component. It takes care of constructing the instance of the port and every object needed by the base port.

Parameters:

	openmaxStandComp	pointer to the Handle of the component
	openmaxStandPort	the ST port to be initialized
	nPortIndex	Index of the port to be constructed
	isInput	specifices if the port is an input or an output

Returns:

OMX_ErrorInsufficientResources if a memory allocation fails
