Struct HdrStaticMeta 

pub struct HdrStaticMeta {
    pub mastering: Option<MasteringDisplay>,
    pub max_content_light_level: Option<u16>,
    pub max_frame_average_light_level: Option<u16>,
}

HDR10 static metadata as carried by the H.264 / H.265 mastering_display_colour_volume and content_light_level_info SEI messages: how the content was graded, which a display sink hands to the driver so the panel maps the highlights the way the colourist saw them.

Each half is independent: a stream may carry either, both, or (then no meta is attached at all) neither. The colour primaries / transfer function / matrix themselves are not here: those are CICP codepoints in the SPS VUI that the decode path already resolves for itself.

Fields

mastering: Option<MasteringDisplay>

max_content_light_level: Option<u16>

MaxCLL: the brightest single pixel in the stream, cd/m^2.

max_frame_average_light_level: Option<u16>

MaxFALL: the brightest frame average in the stream, cd/m^2.

Implementations

impl HdrStaticMeta

pub fn is_empty(&self) -> bool

Whether anything was actually recovered (an all-empty meta is not worth attaching).

Trait Implementations

impl Clone for HdrStaticMeta

fn clone(&self) -> HdrStaticMeta

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for HdrStaticMeta

impl Debug for HdrStaticMeta

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

Formats the value using the given formatter.

impl Default for HdrStaticMeta

fn default() -> HdrStaticMeta

Returns the “default value” for a type.

impl FrameMeta for HdrStaticMeta

fn propagate(&self, _transform: Transform) -> Propagation

A grading description of the content, not of the sample grid: it survives every transform, including a re-encode (the new bitstream describes the same graded picture).

fn as_any(&self) -> &dyn Any

fn as_any_mut(&mut self) -> &mut dyn Any

fn clone_box(&self) -> Box<dyn FrameMeta>

A boxed deep copy of this meta, the GstMeta copy_func analog. Backs the copy-on-write of a shared meta when a tee branch mutates it (see FrameMetaSet::get_mut); each FrameMeta impl is its own concrete type, so the duplication can only be expressed on the trait.

impl PartialEq for HdrStaticMeta

fn eq(&self, other: &HdrStaticMeta) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
