Data Fields
union {
struct {
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.
}   fields
uint16_t   value
}	segment_flags
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 [4]
	Reserved bytes for future use, must be zero.
