Struct HdrMetadata 

pub struct HdrMetadata {
    pub transfer_function: Option<TransferFunction>,
    pub colour_primaries: Option<ColourPrimaries>,
    pub mastering_display: Option<MasteringDisplay>,
    pub content_light_level: Option<ContentLightLevel>,
    pub dolby_vision: Option<DolbyVisionMeta>,
}

Unified HDR metadata attached to a video stream.

Carry exactly the fields present in the source; absent fields are None. Use HdrMetadata::validate before attaching to a mux.

Fields

transfer_function: Option<TransferFunction>

Transfer function (EOTF/OETF).

colour_primaries: Option<ColourPrimaries>

Colour primaries.

mastering_display: Option<MasteringDisplay>

SMPTE ST 2086 mastering display colour volume.

content_light_level: Option<ContentLightLevel>

CTA-861.3 content light level (MaxCLL / MaxFALL).

dolby_vision: Option<DolbyVisionMeta>

Dolby Vision metadata (if present).

Implementations

impl HdrMetadata

pub fn hdr10(mastering: MasteringDisplay, cll: ContentLightLevel) -> Self

Creates a minimal HDR10 metadata bundle with mastering display and CLL.

pub fn hlg() -> Self

Creates a minimal HLG metadata bundle.

pub fn is_hdr(&self) -> bool

Returns true if this bundle carries any HDR signal.

pub fn validate(&self) -> Result<(), HdrError>

Validates all present sub-descriptors.

Errors

Returns an error if any sub-descriptor fails validation.

Trait Implementations

impl Clone for HdrMetadata

fn clone(&self) -> HdrMetadata

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HdrMetadata

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

Formats the value using the given formatter.

impl Default for HdrMetadata

fn default() -> HdrMetadata

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for HdrMetadata

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for HdrMetadata

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

impl Serialize for HdrMetadata

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
