threading.md All five threads, CDVQueue ring buffer, synchronization primitives, shutdown order, post-capture phase
dv-format.md DIF frame structure, SSYB subcode, pack 0x62/0x63, BCD decoding, Y2K pivot, STA error fields, audio error detection
ui-layout.md Dialog architecture, tab control, proportional resize system, status display, CLI commands, error reporting
building.md Prerequisites, CMake and VC6 build steps, SDK paths, linked libraries (v1.6.0)
usb-dv-capture.md USB DV streaming compatibility, known working cameras, troubleshooting

Quick Orientation

WinDV is a single-dialog MFC application layered as follows:

CDVToolsDlg (UI)
  └── CDV (orchestrator, owns pipeline)
        ├── CDVInput / CAVIJoiner   (frame source)
        ├── CDVQueue                (ring buffer)
        ├── CAVIWriter / CDVOutput  (frame sink)
        ├── CMonitor                (preview)
        ├── DVError.cpp/h           (per-frame STA error analysis)
        └── sha256.c/h              (post-capture SHA-256 hash + sidecar)

For the full class hierarchy see architecture.md. For the DirectShow graph topologies see directshow-pipeline.md. For thread roles and synchronisation see threading.md.
