Wild Dragon Dev	b700902200	feat(framecache): phase 4 — capture-manager reads from framecache ... - services/framecache/client/fc_pipe.c: new slot→stdout pipe adapter - Opens framecache slot as consumer (independent cursor per instance) - Streams raw UYVY422 frames to stdout continuously - SIGPIPE detection via write() return — exits cleanly on ffmpeg exit - SIGTERM/SIGINT clean stop from capture-manager - Periodic stats to stderr (every 300 frames) - Exit codes: 0=clean, 1=slot not found, 2=EPIPE - services/framecache/CMakeLists.txt: add fc_pipe target + install - services/framecache/Dockerfile: copy fc_pipe to runtime image - services/capture/Dockerfile: - New fc-pipe-builder stage (builds fc_pipe from framecache sources) - Copies fc_pipe binary to /usr/local/bin/fc_pipe in runtime image - services/capture/src/capture-manager.js: - _buildInputArgs: new framecache path for deltacast + sdi/blackmagic when FC_SLOT_ID env is set (injected by node-agent from bridge fmt JSON) - Spawns fc_pipe <slot_id> as child process - Uses pipe:0 as ffmpeg rawvideo input 0 - Audio FIFO (unchanged) as ffmpeg input 1 - Falls back to legacy FIFO path when FC_SLOT_ID unset - audioMap: covers blackmagic via framecache (input 1 for audio FIFO) - isInterlacedSource: covers blackmagic interlaced signals - hiresStdio: pipe stdin when bridgeProcess set (fc_pipe stdout→ffmpeg) - Non-growing spawn: pipes fc_pipe.stdout → ffmpeg.stdin - Growing orchestrator spawn: pipes fc_pipe.stdout → bash.stdin - sdiHlsDir: covers blackmagic source type - Session state stores _fcPipeProcess for clean stop - stop(): sends SIGTERM to fc_pipe after ffmpeg SIGINT	2026-06-03 15:32:40 +00:00
Wild Dragon Dev	1573bf8954	feat(framecache): phase 1 — framecache container + consumer library ... - services/framecache/: new standalone container - slot.h/slot.c: shm ring buffer (120 frames, FC_MAGIC header, atomic write_cursor, POSIX semaphore per slot) - registry.h/registry.c: in-memory slot registry + /dev/shm/framecache/ registry.json persistence - framecache.c: HTTP API server (libmicrohttpd, port 7435) POST /slots, GET /slots, GET /slots/:id, DELETE /slots/:id, GET /health - fc_client.h/fc_client.c: consumer library — fc_consumer_open/read/close with per-consumer cursor, timeout via sem_timedwait, automatic skip+count when consumer falls behind writer by > ring_depth frames - fc_test_consumer.c: dev utility to attach to any slot and print fps/stats - CMakeLists.txt: framecache server + fc_client static lib + test consumer - Dockerfile: builder + slim runtime stages - docker-compose.worker.yml: add framecache service (profile: capture, ipc: host, shm_size from FC_SHM_SIZE_GB env var, healthcheck) - .env.example: document FC_SHM_SIZE_GB with per-node guidance	2026-06-03 14:53:51 +00:00
