Fields

log2_max_transform_skip_block_size_minus2: u32

log2_max_transform_skip_block_size_minus2 plus 2 specifies the maximum transform block size for which transform_skip_flag may be present in coded pictures referring to the PPS. When not present, the value of log2_max_transform_skip_block_size_minus2 is inferred to be equal to 0. When present, the value of log2_max_transform_skip_block_size_minus2 shall be less than or equal to MaxTbLog2SizeY − 2.

cross_component_prediction_enabled_flag: bool

When set, specifies that log2_res_scale_abs_plus1 and res_scale_sign_flag may be present in the transform unit syntax for pictures referring to the PPS. When not set, specifies that log2_res_scale_abs_plus1 and res_scale_sign_flag are not present for pictures referring to the PPS.

chroma_qp_offset_list_enabled_flag: bool

When set, specifies that the cu_chroma_qp_offset_flag may be present in the transform unit syntax. When not set, specifies that the cu_chroma_qp_offset_flag is not present in the transform unit syntax.

diff_cu_chroma_qp_offset_depth: u32

Specifies the difference between the luma CTB size and the minimum luma coding block size of coding units that convey cu_chroma_qp_offset_flag.

chroma_qp_offset_list_len_minus1: u32

chroma_qp_offset_list_len_minus1 plus 1 specifies the number of cb_qp_offset_list[ i ] and cr_qp_offset_list[ i ] syntax elements that are present in the PPS.

cb_qp_offset_list: [i32; 6]

Specify offsets used in the derivation of Qp′Cb and Qp′Cr, respectively.

cr_qp_offset_list: [i32; 6]

Specify offsets used in the derivation of Qp′Cb and Qp′Cr, respectively.

log2_sao_offset_scale_luma: u32

The base 2 logarithm of the scaling parameter that is used to scale sample adaptive offset (SAO) offset values for luma samples.

log2_sao_offset_scale_chroma: u32

The base 2 logarithm of the scaling parameter that is used to scale SAO offset values for chroma samples.

Trait Implementations

impl Clone for PpsRangeExtension

fn clone(&self) -> PpsRangeExtension

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PpsRangeExtension

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for PpsRangeExtension

fn default() -> PpsRangeExtension

Returns the “default value” for a type.

impl PartialEq for PpsRangeExtension

fn eq(&self, other: &PpsRangeExtension) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
