Struct PicScalingMatrix 

pub struct PicScalingMatrix {
    pub scaling_lists4x4: ScalingLists4x4,
    pub scaling_lists8x8: Option<ScalingLists8x8>,
}

Fields

scaling_lists4x4: ScalingLists4x4

scaling_lists8x8: Option<ScalingLists8x8>

Some when transform_8x8_mode_flag is true, None otherwise

Implementations

impl PicScalingMatrix

pub fn scaling_lists_4x4(&self, sps_chroma: &ChromaInfo) -> [[u8; 16]; 6]

Resolve 4x4 scaling lists using PPS fall-back rules (Table 7-2).

Uses rule set B when the SPS has a scaling matrix (seq_scaling_matrix_present_flag = 1), otherwise rule set A.

pub fn scaling_lists_8x8( &self, sps_chroma: &ChromaInfo, ) -> Option<ScalingLists8x8Resolved>

Resolve 8x8 scaling lists using PPS fall-back rules (Table 7-2).

Returns None when transform_8x8_mode_flag is false (no 8x8 lists in PPS).
