Drop in the redesigned timeline-centric Playout (PGM monitor, transport, SCTE-35 card, as-run drawer) from the on-node redesign, fully wired to the real playout API (channels/transport/HLS preview w/ error-recovery/as-run); no mock data. In-page ConfirmModal for destructive actions. SCTE-35: new playout_scte_breaks table (migration 033), endpoints to schedule/trigger/list/cancel breaks (POST/GET/DELETE /channels/:id/scte[/trigger]), scheduler due-break sweep, engine triggerScte + auto-return + as-run 'scte' rows + on-air SCTE-BREAK state and timeline AD markers. In-stream SCTE-35 cue injection is a documented stub (CasparCG FFMPEG consumer exposes no scte35 muxer) — scheduling/triggering/countdown/as-run are functional.

-- Migration 033 — SCTE-35 ad-break markers for playout.
|
|
--
|
|
-- Adds the missing SCTE-35 splice feature to the playout (MCR) subsystem. An
|
|
-- operator can either schedule an ad break on a channel's timeline (relative to
|
|
-- the active playlist position, or at a wall-clock time) or fire one immediately
|
|
-- ("splice now"). Each break is recorded here and, when fired, also written to
|
|
-- the append-only as-run log so it shows in the compliance record alongside the
|
|
-- clips that aired.
|
|
--
|
|
-- type:
|
|
-- splice_insert — a scheduled break (out → return), duration_s seconds long
|
|
-- immediate — fire-now splice (operator pressed "Trigger ad break now")
|
|
-- splice_out — open-ended avail out (provider break start)
|
|
-- splice_in — return-to-network (provider break end)
|
|
--
|
|
-- status: pending → fired (when the engine acts on it) → done (when the break
|
|
-- window has elapsed). cancelled is set if the operator removes a pending break.
|
|
--
|
|
-- The engine (services/playout) acts on a break by logging the cue, marking the
|
|
-- as-run row, and — where the output path supports it — injecting a real
|
|
-- SCTE-35 cue (see playout-manager.triggerScte for the injection point/TODO).
