SPEC §5 *Broadcast and streaming codecs* registers two sink-supplied payload
capabilities, 2026-10-18, no edition named:
- wai.video.vp8 (RFC 6386): VP8 frames in the IVF frame container, FourCC
VP80, the framing wai.video.vp9 uses. Royalty-free, as VP9. Replicate class
StandardUnclassified: RFC 6386's decoder-conformance text was not read, so
the registry promises no byte identity.
- wai.audio.opus.packet (RFC 6716): one Opus packet (§3), TOC byte first, no
container, the per-packet form a live track carries. No pre-skip or output
gain (those are Ogg Opus's, RFC 7845 §5.1); wai.audio.opus stays the stored
stream. Royalty-free; StandardTolerance as wai.audio.opus (RFC 6716 §6).
Both are standalone, Lossy, outside the floor and the recommended set, and
neither is an LCEVC base. The class functions, the registry table, the
classical list, the glossary links and the registry tests list both; SPEC §7's
class table, the research registry (footnote 15) and the changelog record
them. The generated exports follow in the next commit.
