Fields

pcm_sample_bit_depth_luma_minus1: u8

Defines PcmBitDepth_Y.

pcm_sample_bit_depth_chroma_minus1: u8

Defines PcmBitDepth_C.

log2_min_pcm_luma_coding_block_size_minus3: u64

This value plus 3 specifies the minimum size of coding blocks with pcm_flag equal to true.

Defines Log2MinIpcmCbSizeY.

log2_diff_max_min_pcm_luma_coding_block_size: u64

Specifies the difference between the maximum and minimum size of coding blocks with pcm_flag equal to true.

Defines Log2MaxIpcmCbSizeY.

pcm_loop_filter_disabled_flag: bool

Specifies whether the loop filter process is disabled on reconstructed samples in a coding unit with pcm_flag equal to true.

Implementations

impl Pcm

pub fn pcm_bit_depth_y(&self) -> u8

Specifies the number of bits used to represent each of PCM sample values of the luma component.

The value of PcmBitDepthY is less than or equal to the value of BitDepthY.

PcmBitDepthY = pcm_sample_bit_depth_luma_minus1 + 1 (7-25)

ISO/IEC 23008-2 - 7.4.3.2.1

pub fn pcm_bit_depth_c(&self) -> u8

Specifies the number of bits used to represent each of PCM sample values of the chroma components.

The value of PcmBitDepthC is less than or equal to the value of BitDepthC. When ChromaArrayType is equal to 0, decoders shall ignore its value.

PcmBitDepthC = pcm_sample_bit_depth_chroma_minus1 + 1 (7-26)

ISO/IEC 23008-2 - 7.4.3.2.1

pub fn log2_min_ipcm_cb_size_y(&self) -> u64

The value is range [Min(MinCbLog2SizeY, 5), Min(CtbLog2SizeY, 5)].

Log2MinIpcmCbSizeY = log2_min_pcm_luma_coding_block_size_minus3 + 3

ISO/IEC 23008-2 - 7.4.3.2.1

pub fn log2_max_ipcm_cb_size_y(&self) -> u64

The value is less than or equal to Min(CtbLog2SizeY, 5).

Log2MaxIpcmCbSizeY = log2_diff_max_min_pcm_luma_coding_block_size + Log2MinIpcmCbSizeY

ISO/IEC 23008-2 - 7.4.3.2.1

Trait Implementations

impl Clone for Pcm

fn clone(&self) -> Pcm

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Pcm

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

Formats the value using the given formatter.

impl PartialEq for Pcm

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