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
