- services/framecache/src/net_ingest.c: new network ingest process
- Spawns ffmpeg to decode SRT/RTMP → raw UYVY422 stdout
- Reads decoded frames and writes into framecache slot via shm
- Registers slot with framecache HTTP API on startup
- Deregisters slot on clean exit (SIGTERM)
- Reconnect loop for listener mode (stays alive between sessions)
- --url, --slot-id, --fc-url, --width, --height, --fps-num/den,
--source-type, --listen, --listen-port, --stream-key args
- Emits format JSON to stderr on first frame
- services/framecache/CMakeLists.txt: add net_ingest target
- services/framecache/Dockerfile: copy net_ingest to runtime image
- services/node-agent/index.js:
- startNetIngest() / stopNetIngest(): lifecycle management per recorder
- Spawns net_ingest before sidecar start for srt/rtmp sourceTypes
- Injects FC_SLOT_ID=net-<containerId> into sidecar env
- Sets IpcMode=host for network sidecars using framecache
- Maps temp id → real containerId after container create
- stopNetIngest() called on sidecar stop
- NET_INGEST_BIN env var (default: docker exec framecache net_ingest)
- services/capture/src/capture-manager.js:
- _buildInputArgs srt/rtmp: framecache path when FC_SLOT_ID set
(spawns fc_pipe, uses pipe:0 rawvideo input — same as SDI path)
- Falls back to direct URL when FC_SLOT_ID not set (legacy path)
- audioMap: network via framecache uses '0🅰️0?' (video-only fc_pipe,
no audio FIFO — audio-in-shm is roadmap)
- HLS tee: sdiHlsDir covers network-via-framecache; legacy tee gated
on !FC_SLOT_ID to avoid duplicate HLS outputs
- fc_pipe piped to ffmpeg stdin for network framecache path
- docker-compose.worker.yml: FC_URL + NET_INGEST_BIN in node-agent env
