// SEI payload types form a common namespace between the H.264, H.265
// and H.266 standards.  A given payload type always has the same
// meaning, but some names have different payload types in different
// standards (e.g. scalable-nesting is 30 in H.264 but 133 in H.265).
// The content of the payload data depends on the standard, though
// many generic parts have the same interpretation everywhere (such as
// mastering-display-colour-volume and user-data-unregistered).
