Detailed Description

A wrapper around static HDR metadata.

This class acts as an intermediate format between FFmpeg's HDR metadata structures and the single structure used by the linux kernel. Values are currently scaled/converted as appropriate for those expected by the linux DRM subsystem and may need adjusting for other platforms/APIs.

Note: The linux kernel structures are aligned with the structures defined in the HDMI standards (e.g. CTA-861-G).
