Public Attributes | |
| VABufferID | mb_ctrl |
| 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. | |
| VABufferID | distortion |
| 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). | |
| VABufferID | mv_data |
| 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. | |
| VABufferID | mb_code_data |
| 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). | |
| VABufferID | qp |
| 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. | |
| VABufferID | mv_predictor |
| 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). | |
| uint32_t | num_mv_predictors_l0: 16 |
| number of MV predictors. It must not be greater than maximum supported MV predictor. | |
| uint32_t | search_path: 8 |
| motion search method definition 0: default value, diamond search 1: full search 2: diamond search | |
| uint32_t | len_sp: 8 |
| maximum number of Search Units, valid range is [1, 63] 0 is treated as 1. reference search locations are grouped in a predefined pattern, and all locations within the same group must be either all are chosen or all are skipped. These predefined groups are called search unit (SU). | |
| uint32_t | sub_mb_part_mask: 7 |
| defines the bit-mask for disabling sub-partition The lower 4 bits are for the major partitions (sub-macroblock) and the higher 3 bits for minor partitions (with sub-partition for 4x(8x8) sub-macroblocks. xxxxxx1 : 16x16 sub-macroblock disabled xxxxx1x : 2x(16x8) sub-macroblock within 16x16 disabled xxxx1xx : 2x(8x16) sub-macroblock within 16x16 disabled xxx1xxx : 1x(8x8) sub-partition for 4x(8x8) within 16x16 disabled xx1xxxx : 2x(8x4) sub-partition for 4x(8x8) within 16x16 disabled x1xxxxx : 2x(4x8) sub-partition for 4x(8x8) within 16x16 disabled 1xxxxxx : 4x(4x4) sub-partition for 4x(8x8) within 16x16 disabled 1111111 : Invalid 0000000 : default value | |

| uint32_t | ref_width: 8 |
| motion search window(ref_width * ref_height) | |
| uint32_t | search_window: 4 |
| predefined motion search windows. If selected, len_sp, window(ref_width * ref_eight) and search_path setting are ignored. 0: not use predefined search window 1: Tiny, len_sp=4, 24x24 window and diamond search 2: Small, len_sp=9, 28x28 window and diamond search 3: Diamond, len_sp=16, 48x40 window and diamond search 4: Large Diamond, len_sp=32, 48x40 window and diamond search 5: Exhaustive, len_sp=48, 48x40 window and full search 6: Extend Diamond, len_sp=16, 64x40 window and diamond search 7: Extend Large Diamond, len_sp=32, 64x40 window and diamond search 8: Extend Exhaustive, len_sp=48, 64x40 window and full search | |
