Struct HdrSourceMetadata 

pub struct HdrSourceMetadata {
    pub eotf: TransferFunction,
    pub display_primaries: ColorimetryInfo,
    pub max_display_mastering_luminance: u16,
    pub min_display_mastering_luminance: u16,
    pub max_content_light_level: u16,
    pub max_frame_average_light_level: u16,
}

What the source is emitting.

Units follow CTA-861.3:

field	unit
max_display_mastering_luminance	cd/m², 1 cd/m² steps
min_display_mastering_luminance	0.0001 cd/m² steps
max_content_light_level	cd/m², 1 cd/m² steps
max_frame_average_light_level	cd/m², 1 cd/m² steps

This describes the content, not the display it is going to. A sink that cannot reach these levels tone-maps; that is the sink’s business, and misreporting here to flatter it produces worse results, not better.

Fields

eotf: TransferFunction

Transfer function the content is encoded with.

display_primaries: ColorimetryInfo

Mastering display primaries and white point.

Named by color here; the serializer reorders to the green/blue/red the wire format asks for.

max_display_mastering_luminance: u16

Peak luminance of the mastering display, cd/m².

min_display_mastering_luminance: u16

Black level of the mastering display, in 0.0001 cd/m² steps.

max_content_light_level: u16

Brightest pixel in the content, cd/m².

max_frame_average_light_level: u16

Brightest frame average in the content, cd/m².
