## capture service
- capture-manager.js: add 'deltacast' source_type to _buildInputArgs.
Uses 'deltacast://<index>' with ffmpeg deltacast demuxer when
/dev/deltacast<N> exists; falls back to lavfi testsrc2 + sine test card
(matching deltacast-sdi-recorder standalone app) when hardware absent.
- routes/capture.js: add GET /devices/deltacast endpoint (enumerates
/dev/deltacast* + DELTACAST_PORT_COUNT env fallback). Extend /probe to
handle source_type=deltacast.
## node-agent
- detectHardware(): add 'deltacast' array to capabilities payload.
Enumerates /dev/deltacast* nodes; falls back to DELTACAST_PORT_COUNT env.
Adds DELTACAST_MODEL env support. Logs dc= count in heartbeat line.
- sidecar /start: bind /dev/deltacast* device nodes into capture containers
when sourceType='deltacast'.
## mam-api
- cluster.js: add GET /cluster/devices/deltacast and
GET /cluster/devices/deltacast/signal endpoints — same shape as
blackmagic equivalents for UI parity.
- recorders.js /start: pass DELTACAST_PORT_COUNT env to capture container;
bind /dev/deltacast* device nodes on local spawn.
- migration 024: ALTER TYPE source_type ADD VALUE 'deltacast' (idempotent).
- schema.sql: add 'deltacast' to source_type ENUM for fresh installs.
## web-ui
- modal-new-recorder.jsx: add 'Deltacast' source type card; fetch
/cluster/devices/deltacast on selection; port picker with TEST CARD
badge when hardware absent; falls through to manual index entry if
no devices detected.
DeckLink Duo 2 does not support two simultaneous ffmpeg processes on the
same port. The second (proxy) process immediately gets 'Cannot Autodetect
input stream or No signal', producing an empty upload that could crash the
container before the hires upload completes.
Fix: remove the parallel proxy spawn for SDI entirely. proxyKey is now
always null for SDI recordings (same as SRT/RTMP). needsProxy=true is
already set when proxyKey is null, so the BullMQ worker generates the
proxy from the hires master after stop — same pattern that works for
network sources.
Also revert bad regex change: ffmpeg -sources decklink output on this
hardware uses hex-address format ('81:76669a80:00000000 [DeckLink Duo (1)]')
not bare indented names — original regex was correct.
- capture-manager.js, routes/capture.js: fix ffmpeg -sources decklink
parse regex from v4l2 hex-address format (never matched DeckLink output)
to correct indented-line format. Port 2+ (index 1+) was falling through
to a wrong model-name fallback, causing ffmpeg to open the wrong input
and produce black frames. Now logs the detected device list and the
selected name at start.
- recorders.js (/start): accept per-take projectId override in request
body. If provided, clips go to that project instead of the recorder's
default project_id. Used for both the live-asset INSERT and the
PROJECT_ID env var passed to the capture container.
- screens-ingest.jsx (RecorderRow): add project dropdown shown when
recorder is stopped. Defaults to the recorder's configured project;
operator can change it before hitting Record without editing the
recorder config.
Two things that together stop bogus URLs from masquerading as a recording:
PROBE BUTTON in the New Recorder panel. Before you commit to record, hit Probe Source - the capture container runs ffprobe with a 10s timeout against the URL and returns the parsed streams. UI shows green Signal Detected with codec/resolution/fps/audio, or red No Signal Detected with the actual ffprobe error message. For SDI it lists DeckLink devices. Listener-mode sources cannot be probed standalone (would block waiting for a publisher) and the UI says so.
MAIN STATUS LABEL ON THE RECORDING CARD now mirrors the live signal instead of hardcoding Recording. So a recorder pointed at a dead URL goes Connecting... -> Connection error (red) instead of looking like everything is fine. When frames actually start arriving the label flips to Recording (blue) and the dot turns blue. If a previously-good stream drops the label switches to Signal lost (red).
API:
* capture: POST /capture/probe runs ffprobe and returns { ok, streams, format, error? }
* mam-api: POST /api/v1/recorders/probe proxies through to the capture sidecar with a 15s outer timeout
- Accept source_type, source_url, listen, listen_port, stream_key
- Validate: SDI requires device; SRT/RTMP caller requires source_url
- Pass all params through to captureManager.start()
- On stop: if proxyKey is null (network source), include needsProxy flag
in MAM API registration so worker can generate proxy asynchronously
