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.

Abstract: In one example, a device for processing media content includes a memory configured to store media content; and one or more processors implemented in circuitry and configured to process a first packed region of the media content, wherein to process the first packed region, the one or more processors are configured to unpack the first packed region to produce a first unpacked region, and form a first projected region from the first unpacked region; and process a second packed region of the media content, the second packed region overlapping the first packed region at least in part, wherein to process the second packed region, the one or more processors are configured to unpack the second packed region to produce a second unpacked region, and form a second projected region from the second unpacked region.
