Bringing more versatility to VVC with VSEI
summary
VSEI is a companion spec to VVC that centralizes optional SEI messages so they can be referenced by VVC H.264 HEVC and future codecs its second and third editions are standardized and a fourth is under development New messages include neural network post-filter characteristics which signal a model or a URL and recommended postprocessing order object masking information for per‑pixel masks carried as an auxiliary layer and display overlays with alpha for composited targets plus packed regions constituent rectangles bit‑depth ranges and quality‑metric signaling enabling explicit encoder optimizations and synchronized text tags.
