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
Three problems blocked the end-to-end flow:
1) Library always rendered empty because /assets returns {assets,total} but
index.html (and capture.html) assumed r.data was an array. Fixed in
api.js by unwrapping r.data.assets centrally; total is kept on r.total.
2) SRT/RTMP caller mode pulled audio only. ffmpeg opened the network input
before the H264 SPS arrived, marked the video stream as pix_fmt=none,
and silently dropped it from the stream map. Added -probesize 32M
-analyzeduration 10M -fflags +genpts and explicit -map 0✌️0?/0🅰️0? so
each track survives independently of when it appears.
3) Hitting Record gave no feedback about whether a stream was actually
arriving. capture-manager now parses ffmpeg progress lines (frame=...
fps=...) and tracks framesReceived, currentFps, lastFrameAt, lastError.
getStatus() returns a derived signal enum (connecting | receiving |
lost | error | stopped). The recorder controller gives each spawned
container a stable network alias `recorder-<id>` and the GET
/recorders/:id/status endpoint proxies the live capture status through.
recorders.html polls that every 2s and renders the badge under each
active card with the running frame/fps counter or the ffmpeg error.
Also:
* recorders.html: dropped the listener-mode UI entirely. All new recorders
are caller-mode (pull). The MAM is no longer offered as an RTMP/SRT
server. Legacy listener records still render but read-only.
