584 * \brief Encoding region-of-interest (ROI) attribute. Read-only.
586 * This attribute conveys whether the driver supports region-of-interest (ROI) encoding,
587 * based on user provided ROI rectangles. The attribute value returned indicates the number
588 * of regions that are supported. e.g. A value of 0 means ROI encoding is not supported.
589 * If ROI encoding is supported, the ROI information is passed to the driver using
1336 /** \brief Buffer type used for region-of-interest (ROI) parameters. */
1659 * \brief Encoding region-of-interest (ROI).
1661 * The encoding ROI can be set through this structure, if the implementation
1662 * supports ROI input. The ROI set through this structure is applicable only to the
1664 * VAConfigAttribEncRoi. The encoder will use the ROI information to adjust the QP
1678 /** \brief Defines the ROI boundary in pixels, the driver will map it to appropriate
1683 * priority of the ROI region relative to the non-ROI region. It can positive (more important) or
1684 * negative (less important) values and is compared with non-ROI region (taken as value 0).
1685 * E.g. ROI region with roi_value -3 is less important than the non-ROI region (roi_value implied to be 0)
1686 * which is less important than ROI region with roi_value +2. For overlapping regions, the roi_value
1687 * that is first in the ROI array will have priority. */
