\brief HEVC Inverse Quantization Matrix Buffer Structure

This structure is sent once per frame, and only when scaling_list_enabled_flag = 1. When sps_scaling_list_data_present_flag = 0, app still needs to send in this structure with default matrix values.

Matrix entries are in raster scan order which follows HEVC spec.

Fields

ScalingList4x4: [[u8; 16]; 6]

\brief scaling lists, corresponds to same HEVC spec syntax element ScalingList[ i ][ MatrixID ][ j ].

\brief 4x4 scaling, correspongs i = 0, MatrixID is in the range of 0 to 5, inclusive. And j is in the range of 0 to 15, inclusive.

ScalingList8x8: [[u8; 64]; 6]

\brief 8x8 scaling, correspongs i = 1, MatrixID is in the range of 0 to 5, inclusive. And j is in the range of 0 to 63, inclusive.

ScalingList16x16: [[u8; 64]; 6]

\brief 16x16 scaling, correspongs i = 2, MatrixID is in the range of 0 to 5, inclusive. And j is in the range of 0 to 63, inclusive.

ScalingList32x32: [[u8; 64]; 2]

\brief 32x32 scaling, correspongs i = 3, MatrixID is in the range of 0 to 1, inclusive. And j is in the range of 0 to 63, inclusive.

ScalingListDC16x16: [u8; 6]

\brief DC values of the 16x16 scaling lists, corresponds to HEVC spec syntax scaling_list_dc_coef_minus8[ sizeID - 2 ][ matrixID ] + 8 with sizeID = 2 and matrixID in the range of 0 to 5, inclusive.

ScalingListDC32x32: [u8; 2]

\brief DC values of the 32x32 scaling lists, corresponds to HEVC spec syntax scaling_list_dc_coef_minus8[ sizeID - 2 ][ matrixID ] + 8 with sizeID = 3 and matrixID in the range of 0 to 1, inclusive.

va_reserved: [u32; 4]

\brief Reserved bytes for future use, must be zero

Trait Implementations

impl Clone for _VAIQMatrixBufferHEVC

fn clone(&self) -> _VAIQMatrixBufferHEVC

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for _VAIQMatrixBufferHEVC

impl Debug for _VAIQMatrixBufferHEVC

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

Formats the value using the given formatter.

impl Default for _VAIQMatrixBufferHEVC

fn default() -> Self

Returns the “default value” for a type.

impl Eq for _VAIQMatrixBufferHEVC

impl PartialEq for _VAIQMatrixBufferHEVC

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