 * always get the actual from the component after the param is set. Encoder will receive
 * each input image in full, and shall encode it into tiles in row-major, top-row first,
 * left-to-right order, and send each encoded tile in a separate output buffer. All output
 * buffers for the same input buffer shall carry the same timestamp as the input buffer.
 * If the input buffer is marked EOS, the EOS should only appear on the last output buffer
 * for that input buffer.
 *
 * OMX_VIDEO_CodingHEVC encoders might also receive this param when it's used for image
 * encoding, although in this case the param only serves as a hint. The encoder will
 * receive the input image tiles in row-major, top-row first, left-to-right order.
 * The grid config can be used for quality control, or optimizations.
 *
 * If this param is not set, the component shall assume that grid option is disabled.
 *
 *  nSize                      : Size of the structure in bytes
 *  nVersion                   : OMX specification version information
 *  nPortIndex                 : Port that this structure applies to (output port for encoders)
 *  bEnabled                   : Whether grid is enabled. If true, the other parameters
 *                               specifies the grid config; otherwise they shall be ignored.
 *  nTileWidth                 : Width of each tile.
 *  nTileHeight                : Height of each tile.
 *  nGridRows                  : Number of rows in the grid.
 *  nGridCols                  : Number of cols in the grid.
