+/** \berief 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.
