public final class EXTSurfaceCTA861_3Metadata extends java.lang.ObjectNative bindings to the EXT_surface_CTA861_3_metadata extension.
This extension adds additional EGL surface attributes for the metadata defined by the CTA (Consumer Technology Association) 861.3 standard. This metadata, in addition to the SMPTE 2086 metadata, is used to define the color volume of the mastering display as well as the content (CTA-861.3), The mastering display is the display where creative work is done and creative intent is established. To preserve such creative intent as much as possible and achieve consistent color reproduction on different viewing displays, it is useful for the display pipeline to know the color volume of the original mastering display where content is created or tuned. This avoids performing unnecessary mapping of colors that are not displayable on the original mastering display.
This extension adds the ability to pass the CTA-861.3 metadata via EGL, from which the color volume can be derived. While the general purpose of the metadata is to assist in the transformation between different color volumes of different displays and help achieve better color reproduction, it is not in the scope of this extension to define how exactly the metadata should be used in such a process. It is up to the implementation to determine how to make use of the metadata.
