Expand processor class discovery to include re-exported classes by disabling module-only filtering in package/file scans. Also broaden subclass-check error handling to catch unexpected exceptions and log full context when discovery encounters problematic objects.
Create `dlclivegui/processors/__init__.py` to re-export `register_processor`, `BaseProcessorSocket`, and `PROCESSOR_REGISTRY` from `dlc_processor_socket`, making these APIs available via package-level imports.
Refactors `dlc_processor_socket.py` by removing the in-file example processors and `OneEuroFilter`, and adds them to a new `dlclivegui/processors/examples.py` module. This separates demonstration/experiment-specific logic from the core socket processor implementation, improving maintainability while preserving existing example processor behavior.
Update processor package discovery to ignore `dlc_processor_socket` during namespace scanning, since it only provides the base class/registry and should not be listed as an available processor source. The package fallback scan now uses default class discovery behavior, and related outdated comments/docstring lines were cleaned up.
Change `register_processor` to log a warning instead of raising on duplicate `PROCESSOR_ID` keys, allowing later registrations to override earlier ones without import-time failures. Update subclass save tests to load processor classes from `dlclivegui.processors.examples` via a dedicated fixture, so the parametrized tests validate the concrete example processors against the correct module data path.
Moves processor registration and discovery helpers out of `dlc_processor_socket.py` into a new `registry.py` module so registry access no longer depends on importing socket logic. `dlc_processor_socket.py` now imports the shared registry helpers and adds a safe fallback when `dlclive` is unavailable, reducing import-time failures in environments without that dependency. Package exports were updated to expose registry APIs from the new module.
Centralized recording container configuration by introducing shared allowed/default container constants and using them across settings, UI, and utilities. The recording UI now populates container options from config and keeps the filename extension aligned with the selected container when switching between known video formats, so saved settings and path previews stay consistent.
Introduce a new `DLC_DO_LOG_TIMING` config flag and wire `WorkerTimingStats` into `DLCLiveMainWindow` for DLC enqueue and pose-ready callback timing. The pose callback now logs camera-to-GUI latency in debug mode, marks display state dirty instead of forcing an immediate redraw, and emits periodic timing stats via `maybe_log()`.
Update `_enqueue_frame` to keep enqueueing the newest frame by removing one queued item when `put_nowait` hits `queue.Full`, instead of dropping the incoming frame. This makes processing more real-time under load and keeps enqueue/drop stats consistent, including safe `task_done()` handling.
Demoted multiple verbose runtime messages from INFO to DEBUG in Basler and GenTL backends. This keeps normal logs cleaner by moving routine configuration/readback details (FPS setup, converter mode, exposure/gain settings, trigger configuration, and startup/close diagnostics) out of INFO-level output while preserving the diagnostics when DEBUG is enabled.
Adds fine-grained `WorkerTimingStats` instrumentation across enqueue, initialization, inference, and emit paths, with error/frame accounting and optional timing logging. It also makes worker startup/stop behavior safer by deferring queue creation until RUNNING, blocking enqueue during STARTING, normalizing input frames before inference, and adding richer debug diagnostics (CUDA/runner state and thread stack dumps on stuck shutdown).
Comment out the camera-to-GUI pose latency calculation and debug log in `pose_ready_callback`. This removes the try/except-wrapped timing log path while leaving pose handling and display update behavior unchanged.
Reorders preview teardown so inference is stopped before stopping the multi-camera controller. This avoids stopping the controller while inference is still active and keeps shutdown state cleanup consistent.
Adds a `preserve_mono` option to the GenTL camera backend so Mono pixel formats can remain 2D Mono8 output instead of always converting to BGR. The backend now reports preserve-mono capability, exposes recommended/actual output format based on camera format, and persists detected pixel/output format metadata in settings. It also logs first-frame format details to make runtime format behavior easier to inspect.
Move recording shutdown off the UI thread and finalize it via a Qt signal so stop actions no longer block the interface. RecordingManager now uses a lock-protected recorder map plus a bounded background frame-dispatch queue/thread to decouple frame intake from disk writes, drop frames under sustained backpressure, and cleanly stop/tear down recorders. The recording-with-overlays UI path is also disabled in this change.
