GstVideo.VideoMasteringDisplayInfo

Fields

Name	Type	Access	Description
display_primaries	[GstVideo.VideoMasteringDisplayInfoCoordinates]	r/w	the xy coordinates of primaries in the CIE 1931 color space. the index 0 contains red, 1 is for green and 2 is for blue. each value is normalized to 50000 (meaning that in unit of 0.00002)
max_display_mastering_luminance	int	r/w	the maximum value of display luminance in unit of 0.0001 candelas per square metre (cd/m^2 and nit)
min_display_mastering_luminance	int	r/w	the minimum value of display luminance in unit of 0.0001 candelas per square metre (cd/m^2 and nit)
white_point	GstVideo.VideoMasteringDisplayInfoCoordinates	r/w	the xy coordinates of white point in the CIE 1931 color space. each value is normalized to 50000 (meaning that in unit of 0.00002)
