# Unified Framecache — Implementation Plan
## Context
Replace the current named-FIFO-per-source architecture with a shared-memory
ring buffer (framecache) that fans raw video frames from any ingest source to
unlimited concurrent consumers with zero-copy reads.
**Approved design:** docs/design/framecache/DESIGN.md
**Branch:** feat/unified-framecache
**Roadmap (out of scope here):** RDMA cross-node, AJA, growing-file-while-recording browser playback
---
## Migration Strategy
Ship in 5 phases. Each phase is independently deployable and leaves the system
in a working state. Existing recording workflows are unaffected until Phase 5
cuts over.
---
## Phase 1 — Framecache Container (foundation)
**Goal:** Running framecache service with slot registry. No ingest writers yet.
### 1.1 — Create `services/framecache/` directory structure
```
services/framecache/
src/
framecache.c # main — slot manager + HTTP API
slot.c / slot.h # shm ring buffer lifecycle
registry.c # /dev/shm/framecache/registry.json writer
http.c # lightweight HTTP server (libmicrohttpd)
client/
fc_client.c / fc_client.h # consumer library
fc_client_node/
binding.cc # Node.js N-API addon
binding.gyp
Dockerfile
CMakeLists.txt
```
### 1.2 — Shared memory layout (slot.h)
Each slot lives at `/dev/shm/framecache/<slot_id>`:
```c
#define FC_MAGIC 0x46524D43 // "FRMC"
#define FC_RING_DEPTH 120 // ~2s at 59.94fps
#define FC_HEADER_SIZE 4096 // 4KB header block
typedef struct {
uint32_t magic;
uint32_t version; // = 1
uint32_t width;
uint32_t height;
uint32_t fps_num;
uint32_t fps_den;
uint32_t pixel_format; // FC_PIX_UYVY422 = 0
uint32_t frame_size; // width * height * 2
uint32_t ring_depth; // = FC_RING_DEPTH
_Atomic uint64_t write_cursor; // monotonically increasing frame index
_Atomic uint64_t dropped_frames;
uint8_t _pad[FC_HEADER_SIZE - 48];
} fc_header_t;
typedef struct {
uint64_t pts_us;
uint64_t wall_us;
uint32_t size;
uint8_t data[]; // frame_size bytes
} fc_frame_t;
```
Semaphore: `sem_open("/framecache-<slot_id>-write", ...)` — posted by writer
on each new frame, consumers `sem_timedwait` on it.
### 1.3 — HTTP API (port 7435)
```
POST /slots body: {slot_id, width, height, fps_num, fps_den, source_type}
creates shm region, writes registry entry
201 {slot_id, shm_path, sem_name}
GET /slots 200 [{slot_id, width, height, fps_num, fps_den,
source_type, write_cursor, dropped_frames,
current_fps}]
GET /slots/:id 200 slot detail
DELETE /slots/:id destroys shm + semaphore, removes registry entry, 204
GET /health 200 {status: "ok"}
```
### 1.4 — Registry file
Written to `/dev/shm/framecache/registry.json` on every slot create/delete.
### 1.5 — Dockerfile
```dockerfile
FROM debian:bookworm
RUN apt-get update && apt-get install -y \
build-essential cmake libmicrohttpd-dev \
&& rm -rf /var/lib/apt/lists/*
COPY . /src
RUN cmake -S /src -B /build -DCMAKE_BUILD_TYPE=Release \
&& cmake --build /build -j$(nproc)
EXPOSE 7435
CMD ["/build/framecache"]
```
### 1.6 — docker-compose.worker.yml addition
```yaml
framecache:
build: ./services/framecache
ipc: host
shm_size: '60gb'
environment:
FC_SHM_SIZE: ${FC_SHM_SIZE:-64424509440}
FC_PORT: 7435
ports:
- "7435:7435"
volumes:
- /dev/shm:/dev/shm
restart: unless-stopped
```
### 1.7 — Consumer library (fc_client.c)
```c
fc_slot_t *fc_open(const char *slot_id);
int fc_read_frame(fc_slot_t *slot, fc_frame_t **out, uint64_t timeout_ms);
void fc_close(fc_slot_t *slot);
```
**Commit:** `feat(framecache): phase 1 — framecache container + consumer library`
---
## Phase 2 — Deltacast Bridge writes to framecache
**Goal:** deltacast-bridge writes frames to framecache shm instead of named FIFOs.
Legacy FIFO path kept as compile-time fallback (`-DLEGACY_FIFO=ON`) until Phase 5.
On signal lock:
1. POST /slots to framecache HTTP API
2. shm_open + mmap the slot
3. Video thread writes frame into ring, advances write_cursor atomically, sem_post
4. Audio: keeps writing to audio FIFO (unchanged)
5. On shutdown: DELETE /slots/:id
**Commit:** `feat(framecache): phase 2 — deltacast-bridge writes to shm`
---
## Phase 3 — Blackmagic DeckLink Bridge
**Goal:** New decklink-bridge C program mirrors deltacast-bridge, replaces
ffmpeg -f decklink direct path.
- Uses IDeckLinkIterator to enumerate devices
- VideoInputFrameArrived callback calls fc_write_frame
- Registers slot on signal lock, deregisters on shutdown
- Audio stays in FIFO (same as deltacast)
**Commit:** `feat(framecache): phase 3 — decklink-bridge writes to shm`
---
## Phase 4 — capture-manager reads from framecache
**Goal:** Enables simultaneous growing + proxy + HLS from one SDI input.
- Node.js N-API addon wrapping fc_open/fc_read_frame/fc_close
- capture-manager opens THREE fc_client handles per slot (own cursor each):
1. Growing/master ffmpeg feed
2. Proxy ffmpeg feed
3. HLS preview ffmpeg feed
- Each gets a separate rawvideo pipe to ffmpeg
- Growing MXF workflow (raw2bmx orchestrator) completely unchanged
**Commit:** `feat(framecache): phase 4 — capture-manager reads from framecache`
---
## Phase 5 — Network ingest (RTMP/SRT) into framecache
**Goal:** RTMP and SRT sources decoded to raw UYVY422, written into framecache slots.
- net_ingest process per source: ffmpeg decodes to rawvideo, writes to slot
- capture-manager waits for slot, same fc_client consumer pattern
- Remove legacy FIFO code once all paths go through framecache
**Commit:** `feat(framecache): phase 5 — network ingest via framecache`
---
## Hardware / Deployment
| Node | RAM | /dev/shm | FC_SHM_SIZE |
|------|-----|----------|-------------|
| Baratheon | 251GB | 126GB | 60GB |
| zampp1 | 93GB | 47GB | 40GB |
| zampp2 | 18GB (upgrade) | 9.4GB | 8GB |
Ring buffer per 1080p59.94 source: ~494MB (120 frames × 4.1MB)
All recorder sidecars require `ipc: host`.
---
## Roadmap (not in this branch)
- Audio in framecache shm
- RDMA cross-node slot replication
- AJA hardware support
- Growing-file-while-recording browser HLS playback
- Mastercontrol/playout consumer

/**
* decklink-bridge/main.cpp
*
* Blackmagic DeckLink SDI shared multi-device bridge daemon.
*
* Opens one or more DeckLink devices and for each device:
* - Auto-detects the incoming signal format
* - Registers a framecache slot via HTTP API
* - Writes raw UYVY422 (bmdFormat8BitYUV) video frames into the shm ring
* - Writes PCM s16le audio to a named FIFO (audio-in-shm is roadmap)
*
* Slot ID format: "decklink-<node_id>-<device_index>"
* node_id comes from NODE_ID env var (set by node-agent), falls back to hostname.
*
* Usage:
* decklink-bridge --devices <csv> # device indices, e.g. "0,1"
* decklink-bridge --device <N> # single device compat alias
* [--fc-url http://framecache:7435]
* [--audio-pipe-dir /dev/shm/decklink]
* [--signal-timeout <sec>]
*
* For each device that acquires signal, emits one JSON line to stderr:
* {"device":N,"width":W,"height":H,"fps_num":N,"fps_den":D,
* "interlaced":false,"pix_fmt":"uyvy422",
* "audio_channels":2,"audio_rate":48000,
* "slot_id":"decklink-<node>-<N>"}
*
* Compile with -DLEGACY_FIFO=1 to fall back to writing a raw video FIFO
* instead of the framecache shm path.

* Deltacast VideoMaster SDI shared multi-port bridge daemon.
*
* Opens the board ONCE, opens RX streams for all requested ports, and
* writes each port's video frames into a shared-memory framecache slot
* (and audio to a named FIFO audio-in-shm is a future roadmap item).
*
* Signal fan-out architecture:
* Board video_thread fc_writer /dev/shm/framecache/<slot>
* N consumers (recording, proxy,
* HLS preview) each read with
* their own cursor zero-copy,
* no bandwidth splitting.
* writes each port's video/audio to named FIFOs in a shared directory.
* One reader thread + one audio thread per port run concurrently.
*
* Usage:
* deltacast-bridge --device <N> --ports <csv>
* [--video-pipe-dir /dev/shm/deltacast]
* [--audio-pipe-dir /dev/shm/deltacast]
* [--fc-url http://framecache:7435]
* [--signal-timeout <sec>]
*
* Compat alias: --port <N> treated as --ports <N> (single port).
*
* For each port that acquires signal, emits one JSON line to stderr:
* {"port":N,"width":W,"height":H,"fps_num":N,"fps_den":D,
* "pix_fmt":"uyvy422","audio_rate":48000,"audio_channels":2,
* "slot_id":"deltacast-<device>-<port>"}
*
* Compile with -DLEGACY_FIFO=1 to disable shm writes and fall back to
* the original named-FIFO path (for nodes without framecache running).
* "pix_fmt":"uyvy422","audio_rate":48000,"audio_channels":2}
*
* Runs until SIGTERM/SIGINT, then closes all streams and the board.

/**
* fc_pipe.c Framecache slot stdout pipe adapter.
*
* Opens a framecache slot as a consumer and writes raw video frames to
* stdout in a continuous stream. capture-manager.js spawns this process
* and feeds its stdout to ffmpeg as a rawvideo pipe input identical to
* the way DeckLink bridges currently pipe raw frames.
*
* Each consumer instance has its own independent read cursor, so multiple
* fc_pipe processes reading from the same slot never interfere with each
* other. This is how growing + proxy + HLS all read the same SDI signal
* simultaneously.
*
* Usage:
* fc_pipe <slot_id> [wait_ms]
*
* Writes raw UYVY422 frame data to stdout. Terminates on:
* - SIGTERM / SIGINT (clean stop from capture-manager)
* - stdout EPIPE (ffmpeg exited)
* - Slot disappears (bridge stopped)
*
* Exit codes:
* 0 clean stop (SIGTERM)
* 1 slot not found within wait_ms

/**
* net_ingest.c Network source (RTMP/SRT) framecache slot ingest.
*
* Spawns ffmpeg to decode a network stream to raw UYVY422 on stdout, then
* reads those frames and writes them into a framecache slot via the shm
* ring buffer. Registers the slot with the framecache HTTP API on startup
* and deregisters on clean exit.
*
* Usage:
* net_ingest --url <srt://...|rtmp://...>
* --slot-id <recorder-uuid>
* --fc-url http://framecache:7435
* --width <W> --height <H>
* --fps-num <N> --fps-den <D>
* [--source-type srt|rtmp]
* [--listen] # SRT/RTMP listener mode
* [--listen-port <N>] # listener port (SRT default 9000, RTMP 1935)
* [--stream-key <k>] # RTMP stream key (default "stream")
*
* Emits one JSON line to stderr on first frame:
* {"slot_id":"<id>","width":W,"height":H,"fps_num":N,"fps_den":D,
* "source_type":"srt","pix_fmt":"uyvy422"}
*
* Exits 0 on clean stop (SIGTERM), 1 on error.
*
* The framecache slot stays alive between ffmpeg reconnects (listener mode):
* net_ingest keeps the slot open and restarts ffmpeg on disconnect.

// HEAD reports correct size, full GET (`bytes=0-`) works perfectly, but
// `bytes=8179166-` returns 206 + the right Content-Range header and a zero-
// byte body. A streaming GET from 0 reads cleanly *through* the broken zone.
//
// RustFS issue #143 (empty body on ranged GETs past ~5.9 MB) was fixed in
// RustFS 1.0.0-alpha.94 (PR #2493). Standard ranged GETs used throughout.
// Workaround until the proxy worker emits HLS (planned v1.2.1): stream the
// proxy from offset 0, skip bytes the client didn't ask for, stop after the
// requested end. Browser sees a normal 206 + Content-Range. Mem stays flat;
// extra RustFS-to-mam-api bandwidth = (end+1 - actual-range) per seek.

// - We anchor every chunk's start at a multiple of RUSTFS_SAFE_CHUNK

// - Wait — that puts later starts past the threshold.
// Instead: skip directly to the chunk containing `startByte`, but request
// it as `bytes=anchorStart-end` where anchorStart < threshold. Since the
// bug only bites when the *request start* offset is large, we never issue
// a single GET whose Range start is past the broken zone — we instead
// exploit that a low-offset GET that *continues past* the threshold reads
// cleanly (confirmed by the bytes=0- full-GET probe).
