Abstract
A method and apparatus comprising computer code configured to cause a processor or processors to obtain video data comprising at least one coded picture, identify, by a decoder, at least one first supplementary information enhancement (SEI) message type included with the video data and from a plurality of SEI message types that is required to be processed by the decoder, and the first SEI message type is selected based on a value of a profile indicator; and decode, by the decoder, the video data based on the first SEI message type.
