Johanness 62e2dc49bf cmake: enable MXL tools build by default (testsrc, sink) 2026-06-14 17:03:50 +03:00
Johanness 1ab41b6740 feat: add fabric-bridge node for RDMA/inter-host MXL flow sharing 
- New fabric-bridge node: initiator mode reads local MXL flow and
  transfers via Fabrics (RDMA/TCP); target mode receives remote data
  and commits to local MXL flow writer
- Add set_mxl_instance/get_mxl_instance to Node base class
- CMake option DMF_BUILD_FABRICS=OFF by default (needs libfabric)
- Target publishes target_info in status for out-of-band exchange
- Initiator receives target_info via config parameter

Johanness 34f72c22f0 hardcoded decklink mode fix 2026-05-28 23:43:26 +03:00
Johanness d02223224f feat: add DeckLink input and output nodes 
decklink-in:
- IDeckLinkInputCallback::VideoInputFrameArrived captures V210 frames
- Frame data stored with mutex, copied to MXL grain in process thread
- Uses mxlSleepUntil for TAI-time-based grain pacing
- Configurable: device_index (int), mode (1080i50/1080p50/etc)
- Auto-detect input format via bmdVideoInputEnableFormatDetection
- 1 output port: video_out (V210)

decklink-out:
- Reads V210 grains from MXL, schedules playback via DeckLink output
- Creates IDeckLinkMutableVideoFrame, copies grain data, schedules
- Uses ScheduledFrameCompleted callback for frame completion
- Configurable: device_index (int), mode (1080i50/1080p50/etc)
- 1 input port: video_in (V210)

Both nodes:
- Use DeckLinkAPIDispatch.cpp for CreateDeckLinkIteratorInstance
- Access pixel data via IDeckLinkVideoBuffer (latest SDK API)
- Graceful device open/close on writer/reader add/remove
- Build conditionally via DMF_BUILD_DECKLINK + DECKLINK_SDK_DIR

Johanness 5b5ffa1308 feat: scaffold project framework with engine, node skeleton, and passthrough node 
- CMake build system with vcpkg dependency management
- libdmf-node: Node interface, port definitions, WebSocket control
  server, node runner with MXL lifecycle management
- libdmf-engine: Graph model (nodes/edges CRUD, serialization),
  FlowManager (UUID + V210 NMOS flow definitions), ProcessManager
  (fork/exec node processes), ApiServer (REST API for graph control)
- Passthrough node: reads V210 grains from MXL, copies, writes to MXL
- Unit tests for Graph and FlowManager (6 cases, 21 assertions)
- MXL SDK as git submodule (symlinked from extern/mxl)
