        Initialize with SEI MDCV and CLLI as defined by ISO/IEC 23008-2:2017 `displayData' The value is 24 bytes containing a big-endian structure as defined in D.2.28 Mastering display colour volume SEI message. If nil, uses system defaults. `contentData' The value is 4 bytes containing a big-endian structure as defined in D.2.35 Content light level information SEI message. If nil, uses system defaults. `scale' Scale factor relating (display-referred linear) extended range buffer values (such as MTLPixelFormatRGBA16Float) to optical output of a reference display. Values y in the buffer are assumed to be proportional to the optical output C (in cd/m^2) of a reference display; denoting the opticalOutputScale as C1 (cd/m^2), the relationship is C = C1 * y. As an example, if C1 = 100 cd/m^2, the optical output corresponding to y = 1 is C = C1 = 100 cd/m^2, and the display-referred linear value corresponding to C = 4,000 cd/m^2 is y = 40. If the content, y, is in a normalized pixel format then `scale' is assumed to be 10,000.

      • HLGMetadata

        @NotNull
public static @NotNull CAEDRMetadata HLGMetadata()
        Content is scene referred and originally encoded with the ITU-R BT.2100-2 Hybrid Log Gamma (HLG) opto-electrical transfer function (OETF). The system will apply the opto-optical transfer function (OOTF) based on peak display brightness and ambient. If rendering to a CAMetalLayer with a linear colorspace (for floating point extended dynamic range layers), the content provider must have already applied the HLG inverse OETF.
