Detailed Description

Parses HEVC SEI messages for supplemental video information.

The CHevcSei class is used to interpret and handle Supplemental Enhancement Information (SEI) messages found in High Efficiency Video Coding (HEVC) bitstreams. It is particularly useful for extracting HDR10+ metadata and other types of supplemental data from HEVC encoded video streams.

Note

This class deals with SEI messages in HEVC streams and does not process the video content itself.
