EmptyBufferDone(const CMMFBuffer *, TInt)

TInt	EmptyBufferDone	(	const CMMFBuffer *	aBuffer,
			TInt	aPortIndex
		)	[pure virtual]

Callback method that returns the buffer that has been emptied.

Parameters

const CMMFBuffer * aBuffer	The buffer returned by the OpenMAX component.
TInt aPortIndex	The OpenMAX component's port index returning the buffer.

EventHandler(OMX_EVENTTYPE, TUint32, TUint32, TAny *)

TInt	EventHandler	(	OMX_EVENTTYPE	aEvent,
			TUint32	aData1,
			TUint32	aData2,
			TAny *	aExtraInfo
		)	[pure virtual]

Callback method used by the component to notify the client application of a particular event.

Parameters

OMX_EVENTTYPE aEvent	Event the component wants to notify the application about.
TUint32 aData1	The first integer event-specific parameter.
TUint32 aData2	The second integer event-specific parameter.
TAny * aExtraInfo	A pointer to additional event-specific data the component wants to send to the application. The component owns the memory.

FillBufferDone(CMMFBuffer *, TInt)

TInt	FillBufferDone	(	CMMFBuffer *	aBuffer,
			TInt	aPortIndex
		)	[pure virtual]

Callback method that returns the buffer that has been filled.

Parameters

CMMFBuffer * aBuffer	The buffer returned by the OpenMAX component.
TInt aPortIndex	The OpenMAX component's port index returning the buffer.
