Abstract: In various implementations, provided are techniques, as well as systems that implement these techniques, for SEI messages that distinguish “essential” information from “non-essential” information. In various implementations, an encoder can be configured to determine whether information associated with video data is essential or is not essential. In various implementations, different types of SEI messages can be defined, where one or more of these types of SEI messages can indicate whether information associated with a particular video is essential or not essential. Essential information is required for presenting the video data, and is not required for decoding the video data.
