Struct MkvColorInfo 

pub struct MkvColorInfo {
    pub bits_per_channel: Option<u8>,
    pub chroma_subsampling_horz: Option<u8>,
    pub chroma_subsampling_vert: Option<u8>,
    pub chroma_siting_horz: Option<u8>,
    pub chroma_siting_vert: Option<u8>,
    pub max_cll: Option<u32>,
    pub max_fall: Option<u32>,
    pub mastering: Option<MkvMasteringMetadata>,
}

Extended MKV colour/mastering metadata parsed from Segment → Tracks → TrackEntry → Video → Colour and its nested MasteringMetadata. The core H.273-equivalent fields (matrix / primaries / transfer / full-range) round-trip through StreamInfo.color_metadata on DemuxResult; this struct exists to carry the rest (bits_per_channel, chroma siting / subsampling offsets, MaxCLL/MaxFALL, SMPTE-2086 mastering chromaticities) without requiring a breaking extension of the shared StreamInfo type in the codec crate.

Populated by demux::probe_mkv_color_info for callers that need it (mux HDR signalling, future SEI passthrough). Returns None for non-MKV containers and for MKVs with no Colour element.

Fields

bits_per_channel: Option<u8>

MatroskaElement 0x55B2 — decoded bits per channel (e.g. 10 for HDR10 sources).

chroma_subsampling_horz: Option<u8>

MatroskaElement 0x55B3 — Cb/Cr horizontal subsampling ratio.

chroma_subsampling_vert: Option<u8>

MatroskaElement 0x55B4 — Cb/Cr vertical subsampling ratio.

chroma_siting_horz: Option<u8>

MatroskaElement 0x55B7 — horizontal chroma siting (0=unspecified, 1=left-collocated, 2=half).

chroma_siting_vert: Option<u8>

MatroskaElement 0x55B8 — vertical chroma siting.

max_cll: Option<u32>

MatroskaElement 0x55BC — MaxCLL in cd/m².

max_fall: Option<u32>

MatroskaElement 0x55BD — MaxFALL in cd/m².

mastering: Option<MkvMasteringMetadata>

MatroskaElement 0x55D0 nested — SMPTE ST 2086 mastering display primaries + luminance. Emitted when any sub-element is present.

Trait Implementations

impl Clone for MkvColorInfo

fn clone(&self) -> MkvColorInfo

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MkvColorInfo

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

Formats the value using the given formatter.

impl Default for MkvColorInfo

fn default() -> MkvColorInfo

Returns the “default value” for a type.

impl PartialEq for MkvColorInfo

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