Playback
The Playback router provides video streaming and thumbnail access via presigned URLs served through cdn.lynxvizion.com (Cloudflare CDN). All endpoints return redirects to presigned URLs that expire after 1 hour.
No authentication required — endpoints use non-guessable UUIDs (job_id) as implicit authorization.
