Fields

base_q_idx: u32

Indicates the base frame qindex. This is used for Y AC coefficients and as the base value for the other quantizers.

diff_uv_delta: bool

Indicates the base frame qindex. This is used for Y AC coefficients and as the base value for the other quantizers.

using_qmatrix: bool

Specifies that the quantizer matrix will be used to compute quantizers.

qm_y: u32

Specifies the level in the quantizer matrix that should be used for luma plane decoding.

qm_u: u32

Specifies the level in the quantizer matrix that should be used for chroma U plane decoding.

qm_v: u32

Specifies the level in the quantizer matrix that should be used for chroma V plane decoding.

delta_q_present: bool

Specifies whether quantizer index delta values are present.

delta_q_res: u32

Specifies the left shift which should be applied to decoded quantizer index delta values.

delta_q_y_dc: i32

Same as DeltaQYDc

delta_q_u_dc: i32

Same as DeltaQUDc

delta_q_u_ac: i32

Same as DeltaQUAc

delta_q_v_dc: i32

Same as DeltaQVDc

delta_q_v_ac: i32

Same as DeltaQVAc

Trait Implementations

impl Clone for QuantizationParams

fn clone(&self) -> QuantizationParams

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for QuantizationParams

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

Formats the value using the given formatter.

impl Default for QuantizationParams

fn default() -> QuantizationParams

Returns the “default value” for a type.

impl PartialEq for QuantizationParams

fn eq(&self, other: &QuantizationParams) -> 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.
