}Evidence claims
- [sourced_fact] Page documents protocol version 1.0.1: per-sample camera pose (meters, pan/tilt/roll degrees), lens distortion/focus/iris/zoom, timecode and sync status, static metadata about every 2 seconds. · locator: Data and static metadata sections source
- [sourced_fact] Transport is typically IPv4 UDP, multicast recommended (239.135.1.x), default port 55555, JSON or CBOR payloads with Fletcher-16 checksum, unidirectional; IPv6 not supported. · locator: Transport section source
- [sourced_fact] Page links the camdkit reference toolkit, Mo-Sys opentrackio-cpp, a JSON schema and the OpenLensIO lens model PDF; it contains no license statement. · locator: Links section source
- [upstream_claim] Research review verdict at export: reviewed (as of 2026-10-17). Recorded by the research pipeline, not a hub review outcome; evidence.review stays unreviewed until an independent reviewer records one.
