	De-initializes the component.
bool	getData (uint64_t sourceID, uint8_t *pDest, int *width, int *height, MIPTime *t=0)
	Returns video frame data for source sourceID.
bool	getSourceIDs (std::list< uint64_t > &sourceIDs)
	Fills in the list sourceIDs with the IDs of sources of which video frames are currently being stored.

bool MIPVideoFrameStorage::getData	(	uint64_t	sourceID,
		uint8_t *	pDest,
		int *	width,
		int *	height,
		MIPTime *	t = 0
	)

This function accesses the last video frame for a specific source.

Parameters:

sourceID	The ID of the source whose video frame you which to access.
pDest	Buffer to store the video frame data in, in YUV420P format. If the parameter is NULL, the video frame is not copied. The buffer must be large enough to store the frame in.
width	If not NULL, the width of the video frame is stored in *width.
height	If not NULL, the width of the video frame is stored in *height.
t	If not NULL, the time at which the video frame was received is stored in *t.
