Describes High Dynamic Range Meta Data for HDR10.
Specifies the colour volume(the colour primaries, white point and luminance range) of a display considered to be the mastering display for the associated video content -e.g., the colour volume of a display that was used for viewing while authoring the video content. See ITU-T H.265 D.3.27 Mastering display colour volume SEI message semantics.
Specifies upper bounds for the nominal light level of the content. See ITU-T H.265 D.3.35 Content light level information SEI message semantics.
This structure can be used to indicate the HDR10 metadata for 1) the content which was authored; 2) the display on which the content will be presented. If it is for display, max_content_light_level and max_pic_average_light_level are ignored.
uint16_t VAHdrMetaDataHDR10::display_primaries_x[3] |
X chromaticity coordinate of the mastering display.
Index value c equal to 0 should correspond to the green primary. Index value c equal to 1 should correspond to the blue primary. Index value c equal to 2 should correspond to the red primary. The value for display_primaries_x shall be in the range of 0 to 50000 inclusive.
uint16_t VAHdrMetaDataHDR10::display_primaries_y[3] |
Y chromaticity coordinate of the mastering display.
Index value c equal to 0 should correspond to the green primary. Index value c equal to 1 should correspond to the blue primary. Index value c equal to 2 should correspond to the red primary. The value for display_primaries_y shall be in the range of 0 to 50000 inclusive.
uint16_t VAHdrMetaDataHDR10::max_content_light_level |
The maximum content light level (MaxCLL).
The value is in units of 1 candelas per square metre.
uint32_t VAHdrMetaDataHDR10::max_display_mastering_luminance |
The maximum display luminance of the mastering display.
The value is in units of 0.0001 candelas per square metre.
uint16_t VAHdrMetaDataHDR10::max_pic_average_light_level |
The maximum picture average light level (MaxFALL).
The value is in units of 1 candelas per square metre.
uint32_t VAHdrMetaDataHDR10::min_display_mastering_luminance |
The minumum display luminance of the mastering display.
The value is in units of 0.0001 candelas per square metre.

uint16_t VAHdrMetaDataHDR10::white_point_x |
X chromaticity coordinate of the white point of the mastering display.
The value for white_point_x shall be in the range of 0 to 50000 inclusive.
uint16_t VAHdrMetaDataHDR10::white_point_y |
Y chromaticity coordinate of the white point of the mastering display.
The value for white_point_y shall be in the range of 0 to 50000 inclusive.
