 /*! \brief Defines ROI settings.
 *
 *    {Top, Bottom, Left, Right} defines the ROI boundary. The values are in unit of blocks. The block size M should use LCU size (e.g. sif LCU size is 32x32, M is 32). And its range should be within the frame boundary, so that:
 *        0 <= Top <= Bottom <= (FrameHeight+ M-1)/M -1
 *        0 <= Left <= Right <= (FrameWidth+M-1)/M-1
 *    If input range is out of frame boundary, driver should trim it.
 *    ROI alignes with LCU based rectangular blocks and cannot have arbitrary pixel-based location.
 *    Region overlapping is allowed. For MBs reside within more than one ROIs, parameters from ROI with smaller index rules. For example, when ROI[0] and ROI[1] overlap on a certain area, the QP value for the overlapped area will be determined by value of ROI[0]. The order of ROI[] reflects objects’ relative relationship of depth. Foreground objects should have ROI index smaller than background objects.

For ROIValueInDeltaQP equals 0BRC cases, this parameter describes the priority level of the ROI region. Value range [-3..3]. The higher the absolute value, the bigger range of delta QP is allowed. And it is usually applies on BRC case. BRC will decide the actual delta QP value. Positive priority level means negative delta QP should be applied. And negative priority level means positive delta QP which implies the region should be intentionally blurred. In either case, value Priority level 0 means same as non-ROI region. It is suggested that application does not set value 0. But if it happens, driver will treat that ROI as part of non-ROI background.

	* ROI alignes with LCU based rectangular blocks and cannot have arbitrary pixel-based location.
	* Region overlapping is allowed. For MBs reside within more than one ROIs, parameters from ROI with smaller index rules. For example, when ROI[0] and ROI[1] overlap on a certain area, the QP value for the overlapped area will be determined by value of ROI[0]. The order of ROI[] reflects objects’ relative relationship of depth. Foreground objects should have ROI index smaller than background objects.
