This application relates to video encoding and decoding, and specifically to tools and techniques for using and providing supplemental enhancement information in bitstreams. Among other things, the detailed description presents innovations for bitstreams having supplemental enhancement information (SEI). In particular embodiments, the SEI message includes picture source data (e.g., data indicating whether the associated picture is a progressive scan picture or an interlaced scan picture and/or data indicating whether the associated picture is a duplicate picture). The SEI message can also express a confidence level of the encoder's relative confidence in the accuracy of this picture source data. A decoder can use the confidence level indication to determine whether the decoder should separately identify the picture as progressive or interlaced and/or a duplicate picture or honor the picture source scanning information in the SEI as it is.
In a computer system that implements a video encoder, a method comprising:
A computer system comprising one or more processing units and memory, wherein the computer system implements a video decoder configured to perform operations comprising:
One or more non-transitory computer-readable media having stored thereon encoded data in at least part of a bitstream, the encoded data including, in a syntax structure, multiple syntax elements that indicate one of multiple possible options for a scan type for the video content and degree of confidence in the scan type for the video content, wherein each of the multiple possible options can be indicated with the multiple syntax elements, the multiple possible options including:
