}Fields§
§function: u32§mb_ctrl: u32\brief MB (16x16) control input buffer. It is valid only when (mb_input | mb_size_ctrl) is set to 1. The data in this buffer correspond to the input source. 16x16 MB is in raster scan order, each MB control data structure is defined by VAEncFEIMBControlH264. Buffer size shall not be less than the number of 16x16 blocks multiplied by sizeof(VAEncFEIMBControlH264). Note: if mb_qp is set, VAEncQPBufferH264 is expected.
distortion: u32\brief distortion output of MB ENC or ENC_PAK. Each 16x16 block has one distortion data with VAEncFEIDistortionH264 layout Buffer size shall not be less than the number of 16x16 blocks multiplied by sizeof(VAEncFEIDistortionH264).
mv_data: u32\brief MVs data output of MB ENC. Each 16x16 block has one MVs data with layout VAMotionVector Buffer size shall not be less than the number of 16x16 blocks multiplied by sizeof(VAMotionVector) * 16.
mb_code_data: u32\brief MBCode data output of MB ENC. Each 16x16 block has one MB Code data with layout VAEncFEIMBCodeH264 Buffer size shall not be less than the number of 16x16 blocks multiplied by sizeof(VAEncFEIMBCodeH264).
qp: u32\brief QP input buffer with layout VAEncQPBufferH264. It is valid only when mb_qp is set to 1. The data in this buffer correspond to the input source. One QP per 16x16 block in raster scan order, each QP is a signed char (8-bit) value.
mv_predictor: u32\brief MV predictor. It is valid only when mv_predictor_enable is set to 1. Each 16x16 block has one or more pair of motion vectors and the corresponding reference indexes as defined by VAEncFEIMVPredictorH264. 16x16 block is in raster scan order. Buffer size shall not be less than the number of 16x16 blocks multiplied by sizeof(VAEncFEIMVPredictorH264).

num_passes: u32\brief number of passes, every pass has different QP
delta_qp: *mut u8\brief delta QP list for every pass
