Struct TransformSimd 

pub struct TransformSimd<S> { /* private fields */ }

AV1 transform SIMD operations.

Implementations

impl<S: SimdOpsExt> TransformSimd<S>

pub const fn new(simd: S) -> Self

Create a new transform SIMD instance.

pub fn forward_dct_4x4(&self, input: &[i16; 16], output: &mut [i16; 16])

Forward DCT 4x4 transform.

Input: 4x4 block of residuals (i16) Output: 4x4 block of transform coefficients (i16)

pub fn inverse_dct_4x4(&self, input: &[i16; 16], output: &mut [i16; 16])

Inverse DCT 4x4 transform.

pub fn forward_dct_8x8(&self, input: &[i16; 64], output: &mut [i16; 64])

Forward DCT 8x8 transform.

pub fn inverse_dct_8x8(&self, input: &[i16; 64], output: &mut [i16; 64])

Inverse DCT 8x8 transform.

pub fn forward_adst_4x4(&self, input: &[i16; 16], output: &mut [i16; 16])

Forward ADST 4x4 transform.

Asymmetric Discrete Sine Transform used for directional prediction residuals.

pub fn inverse_adst_4x4(&self, input: &[i16; 16], output: &mut [i16; 16])

Inverse ADST 4x4 transform.

pub fn identity_4x4(&self, input: &[i16; 16], output: &mut [i16; 16])

Identity transform (no transform, just scaling).
