Public Attributes | |
| uint8_t | filter_level [4][2] |
| Specifies the filter level information per segment. The value corresponds to variable lfi->lvl[seg][ref][mode] in VP9 code, where m is [ref], and n is [mode] in FilterLevel[m][n]. | |
| int16_t | luma_ac_quant_scale |
| Specifies per segment Luma AC quantization scale. Corresponding to y_dequant[qindex][1] in vp9_mb_init_quantizer() function of VP9 code. | |
| int16_t | luma_dc_quant_scale |
| Specifies per segment Luma DC quantization scale. Corresponding to y_dequant[qindex][0] in vp9_mb_init_quantizer() function of VP9 code. | |
| int16_t | chroma_ac_quant_scale |
| Specifies per segment Chroma AC quantization scale. Corresponding to uv_dequant[qindex][1] in vp9_mb_init_quantizer() function of VP9 code. | |
| int16_t | chroma_dc_quant_scale |
| Specifies per segment Chroma DC quantization scale. Corresponding to uv_dequant[qindex][0] in vp9_mb_init_quantizer() function of VP9 code. | |
| uint32_t | va_reserved [VA_PADDING_LOW] |
| Reserved bytes for future use, must be zero. | |
| uint16_t | segment_reference_enabled: 1 |
| Indicates if per segment reference frame indicator is enabled. Corresponding to variable feature_enabled when j == SEG_LVL_REF_FRAME in function setup_segmentation() VP9 code. | |
| uint16_t | segment_reference: 2 |
| Specifies per segment reference indication. 0: reserved 1: Last ref 2: golden 3: altref Value can be derived from variable data when j == SEG_LVL_REF_FRAME in function setup_segmentation() VP9 code. | |
| uint16_t | segment_reference_skipped: 1 |
| Indicates if per segment skip feature is enabled. Corresponding to variable feature_enabled when j == SEG_LVL_SKIP in function setup_segmentation() VP9 code. | |
VP9 Segmentation Parameter Data Structure.
This structure conveys per segment parameters. 8 of this data structure will be included in VASegmentationParameterBufferVP9 and sent to API in a single buffer.
