Overview

Embeds and extracts C2PA manifest references in WebVTT files using NOTE blocks with ASCII armour delimiters. The manifest is placed immediately after the WEBVTT header, where it survives HLS/DASH segmentation.

WEBVTT

NOTE -----BEGIN C2PA MANIFEST----- https://example.com/m.c2pa -----END C2PA MANIFEST-----
