test pyuvc

- Introduced VideoPlayer class to handle local video playback, emitting frames via frame_ready signal.
- Updated MainWindow to switch between camera and video sources, integrating video playback controls.
- Enhanced AppMenuBar with options to open video files and manage inference models.
- Implemented BboxOverlay for displaying detection results on video frames.
- Added InferenceManager to manage YOLO inference in a separate process, with error handling and restart logic.
- Created tests for BboxOverlay and InferenceManager to ensure functionality and robustness.
- Updated pyproject.toml to include optional dependencies for inference support.

-# MVP Implementation Plan — Duck Preview
+# Plan działania — MVP Camera Preview (PySide6)
 
-## Stack
+## Środowisko
 
-- **Language:** Python 3.12
-- **GUI/Framework:** PySide6 6.11 (QtMultimedia + QtWidgets)
-- **Camera backend:** QCamera + QMediaCaptureSession + QVideoSink (native GPU)
-- **Rendering:** QWidget (paintEvent) z QPainter — manual render z QVideoFrame → QImage
-- **Testing:** pytest
-- **Linting/Formatting:** ruff
-
-## Architecture
-
-```
-CameraService
-  └─ QVideoSink.videoFrame ──→ FrameDispatcher.on_frame
-                                   ├─ VideoWidget.on_frame  (render klatki)
-                                   ├─ TelemetryCollector.on_frame  (timestamp)

-## Kolejność implementacji
-
-### 0. Project scaffolding
-`pyproject.toml` — projekt, zależność PySide6, entry point, ruff config, pytest
-`duck_preview/__init__.py`, `__main__.py` — entry point `python -m duck_preview`
-Podkatalogi: `camera/`, `dispatcher/`, `rendering/`, `telemetry/`
-
-### 1. CameraService (`camera/service.py`)
-- Wrapper na `QCamera` + `QMediaCaptureSession` + `QVideoSink`
-- `available_cameras()` — static, zwraca listę `QCameraDevice` z `QMediaDevices`
-- `start(device)` / `stop()` — zarządzanie cyklem życia kamery
-- `set_camera_format(fmt)` — zmiana rozdzielczości/FPS
-- `sink` property — QVideoSink do podpięcia dispatchera
-- `error_occurred` Signal — propagacja błędów kamery
-
-### 2. FrameDispatcher (`dispatcher/frame_dispatcher.py`)
-- Prosty pub/sub: `subscribe(cb)` / `unsubscribe(cb)`
-- `on_frame(frame)` — wołany z sygnału QVideoSink, iteruje wszystkich subskrybentów
-- Frame dropping: na razie brak (wszystkie callbacki szybkie)
-
-### 3. TelemetryCollector (`telemetry/collector.py`)
-- Subskrybent dispatchera
-- Zbiera timestampy (`deque`, maxlen=500)
-- `metrics()` → dict: fps (klatki z ostatniej sekundy), frame_time_ms (średnia delta między klatkami), frame_count
-- Brak CPU usage (out of scope na MVP)
-
-### 4. VideoWidget (`rendering/video_widget.py`)
-- `QWidget` z `WA_OpaquePaintEvent`
-- `on_frame(frame)` — `frame.toImage()` → zapis QImage → `update()`
-- `paintEvent` — skalowanie z zachowaniem proporcji, centrowanie, letterboxing
-- Brak klatek → wyświetla "No camera feed"
-
-### 5. OverlayWidget (`rendering/overlay.py`)
-- Przezroczysty QWidget (`WA_TransparentForMouseEvents`)
-- Nakładka na video, rysuje tekst metryk (FPS, frame time, frame count)
-- Semi-transparentne tło, zielona czcionka Consolas
-- Toggle widoczności przez menu Debug
-
-### 6. MainWindow (`main_window.py`)
-- `QMainWindow` z menu barem:
-  - **Camera** — lista dostępnych kamer (dynamiczna, reaguje na `videoInputsChanged`)
-  - **Resolution** — dostępne rozdzielczości dla wybranej kamery
-  - **FPS** — dostępne FPS dla wybranej rozdzielczości
-  - **Debug** — toggle nakładki
-- Central widget: GridLayout z VideoWidget + OverlayWidget (stacked)
-
-### 7. App (`app.py`)
-- `main()` — tworzy QApplication, instancjonuje i łączy zależności (ręczne DI)
-- Wire: camera.sink → dispatcher.on_frame
-- Wire: dispatcher → telemetry.on_frame, video_widget.on_frame
-- QTimer 200ms: telemetry.metrics() → overlay.set_metrics()
-- `__main__.py` → `from duck_preview.app import main; main()`

+
+#### 0.2 Pliki konfiguracyjne
+
+- `pyproject.toml` — konfiguracja ruff (linter/formatter) i pytest
+- `requirements.txt` — zależności produkcyjne (PySide6)
+- `requirements-dev.txt` — zależności deweloperskie (pytest, ruff)
+- `.gitignore` — aktualizacja o artefakty Pythona
+
+---
+
+### Faza 1 — Camera Service
+
+Cel: stabilne pobranie obrazu z kamery przez QtMultimedia.
+
+#### 1.1 Camera Enumerator
+
+- `QMediaDevices.videoInputs()` — lista dostępnych kamer
+- Zwraca listę `QCameraDevice` z nazwą, id i obsługiwanymi formatami
+- Obsługa braku kamer (komunikat, nie crash)
+- Test jednostkowy: mockowanie `QMediaDevices`
+
+#### 1.2 Camera Service
+
+- Opakowuje `QCamera` + `QMediaCaptureSession`
+- API:
+  - `start(device: QCameraDevice)` — uruchamia kamerę
+  - `stop()` — zatrzymuje kamerę
+  - `set_resolution(width, height)` — ustawia format
+  - `set_fps(fps)` — ustawia docelowy FPS
+  - `reconnect()` — restart po błędzie
+- `QVideoSink` jako punkt odbioru klatek
+- Sygnał `frame_ready(QVideoFrame)` do Frame Dispatcher
+- Obsługa błędów kamery (`QCamera.errorOccurred`)
+
+#### 1.3 Uwagi platformowe
+
+| Aspekt | Windows 11 (dev) | macOS Ventura (target) |
+|---|---|---|
+| Backend | DirectShow / Media Foundation | AVFoundation |
+| Kamera ELP | USB, standardowy UVC driver | USB, UVC |
+| Format klatek | YUYV / MJPEG | YUYV / MJPEG |
+| GPU rendering | ANGLE (OpenGL ES) | Metal |
+
+---
+
+### Faza 2 — Frame Dispatcher
+
+Cel: dystrybucja klatek do wielu odbiorców bez blokowania akwizycji.
+
+#### 2.1 Frame Dispatcher
+
+- Wzorzec: publish-subscribe (lista callbacków)
+- `subscribe(callback: Callable[[QVideoFrame], None])`
+- `unsubscribe(callback)`
+- `dispatch(frame: QVideoFrame)` — wywołuje wszystkich subskrybentów
+- Klatki NIE są kopiowane — subskrybenci działają na referencji
+- Subskrybenci mogą **pominąć klatkę** (tryb drop-if-busy)
+- Wywołanie `dispatch` następuje w wątku GUI (slot połączony z `frame_ready`)
+
+#### 2.2 Subskrybenci w Fazie 1
+
+| Subskrybent | Działanie |
+|---|---|
+| Video Renderer | przekazuje klatkę do `QVideoSink` / `QVideoWidget` |
+| Telemetry Collector | mierzy czas, zlicza klatki |
+
+---
+
+### Faza 3 — Video Renderer
+
+Cel: renderowanie klatki w GUI bez zbędnych kopii.
+
+#### 3.1 Podejście
+
+- `QVideoWidget` jako główny widget podglądu
+- `QMediaCaptureSession.setVideoOutput(QVideoWidget)` — ścieżka bezpośrednia, zero kopii
+- Alternatywnie: `QVideoSink` → `QGraphicsVideoItem` dla przyszłych overlayów
+- Domyślnie: `QVideoWidget` (prosta, niska latencja)
+
+#### 3.2 Wymagania
+
+- Preview nie blokuje wątku GUI
+- Obsługa aspect ratio (letter/pillarbox)
+- Resize okna bez migotania
+
+---
+
+### Faza 4 — Telemetry Collector
+
+Cel: dokładne metryki pipeline'u wideo.
+
+#### 4.1 Zbierane metryki
+
+| Metryka | Metoda pomiaru |
+|---|---|
+| Realtime FPS | licznik klatek / okno 1 s |
+| Frame time | `time.perf_counter()` między klatkami |
+| Frame acquisition time | timestamp wejście frame_ready → dispatch |
+| Rendering time | czas `QVideoWidget.update()` (opcjonalnie) |
+| Dropped frames | detekcja przez numerację lub timestamp gap |
+| CPU usage | `psutil.cpu_percent()` (dodać do requirements) |
+| Memory usage | `psutil.virtual_memory()` (opcjonalnie) |
+
+#### 4.2 API
+
+- `TelemetryCollector` — subskrybent Frame Dispatcher
+- `on_frame(frame: QVideoFrame)` — rejestruje timestamp klatki
+- `get_snapshot() -> TelemetrySnapshot` — aktualny stan metryk (dataclass)
+- `update_interval_ms: int` — jak często odświeżać snapshot (domyślnie 500 ms)
+- Sygnał `metrics_updated(TelemetrySnapshot)` — emitowany co `update_interval_ms`
+
+#### 4.3 TelemetrySnapshot (dataclass)
+
+```python
+@dataclass
+class TelemetrySnapshot:
+    fps: float
+    frame_time_ms: float
+    dropped_frames: int
+    cpu_percent: float
+    memory_mb: float | None
+    timestamp: float
 ```
 
 ---
 
-## Edge cases / uwagi
+### Faza 5 — Overlay System
 
-- Brak kamer → menu Camera pokazuje "No cameras detected"
-- Brak klatek → VideoWidget pokazuje ciemne tło + napis
-- Błąd kamery → CameraService emituje `error_occurred` (na razie tylko log)
-- Zamknięcie okna → `closeEvent` → `camera.stop()`
-- QVideoFrame.toImage() kopiuje dane — akceptowalne dla MVP
-- Wszystkie obiekty żyją w main thread — brak problemów z threadingiem
+Cel: wyświetlanie metryk na przezroczystej warstwie nad podglądem.
+
+#### 5.1 Architektura
+
+- `OverlayWidget(QWidget)` — przezroczysty widget (`WA_TransparentForMouseEvents`)
+- Pozycjonowany absolutnie nad `QVideoWidget` (ten sam parent, wyższy z-index)
+- `paintEvent` rysuje semi-przezroczysty prostokąt + tekst z metrykami
+- Połączony z sygnałem `metrics_updated` — odświeża tylko gdy dane się zmienią
+
+#### 5.2 Zawartość overlaya (MVP)
+
+```
+FPS:    60.0
+Frame:  16.7 ms
+Drop:   0
+CPU:    12.3 %
+```
+
+#### 5.3 Sterowalność
+
+- Widoczność overlaya: toggle przez menu Debug
+- Pozycja: lewy górny róg (stała w MVP)
+- Kolor tła: `rgba(0, 0, 0, 160)`
+
+---
+
+### Faza 6 — GUI / Main Window
+
+Cel: minimalne, funkcjonalne okno aplikacji.
+
+#### 6.1 MainWindow
+
+- `QMainWindow` z `QVideoWidget` jako central widget
+- `OverlayWidget` nałożony na video
+- Obsługa resize → reposition overlay
+- Tytuł okna: `Duck Preview`
+
+#### 6.2 MenuBar
+
+Menu **Camera**:
+- Lista wykrytych kamer (radio-style)
+- Separator
+- Reconnect
+
+Menu **Video**:
+- Resolution submenu (pobierane dynamicznie z `QCameraDevice.videoFormats()`)
+- FPS submenu
+
+Menu **Debug**:
+- Toggle overlay metryk
+- Logowanie do konsoli (toggle)
+
+#### 6.3 Startup flow
+
+```
+main.py
+  → QApplication
+  → CameraEnumerator.list_cameras()
+  → MainWindow(cameras)
+  → CameraService.start(cameras[0])  # pierwsza kamera lub ELP
+  → FrameDispatcher.subscribe(telemetry, renderer)
+  → app.exec()
+```
+
+---
+
+### Faza 7 — Testy i walidacja
+
+#### 7.1 Testy jednostkowe
+
+| Moduł | Co testować |
+|---|---|
+| `CameraEnumerator` | lista kamer, brak kamer, format danych |
+| `TelemetryCollector` | obliczenia FPS, wykrywanie dropów |
+| `FrameDispatcher` | subskrypcja, odsubskrypcja, dispatch |
+| `TelemetrySnapshot` | poprawność dataclass |
+
+#### 7.2 Testy manualne (Windows dev)
+
+- [ ] Uruchomienie z kamerą laptopa / USB webcam
+- [ ] Przełączanie kamer
+- [ ] Zmiana rozdzielczości
+- [ ] Zmiana FPS
+- [ ] Toggle overlay
+- [ ] Reconnect po odłączeniu kamery
+
+#### 7.3 Testy na Mac Mini (target)
+
+- [ ] Wykrycie kamery ELP
+- [ ] Poprawny format YUYV/MJPEG
+- [ ] Wydajność AVFoundation vs DirectShow
+- [ ] GPU rendering przez Metal
+
+#### 7.4 Kryteria sukcesu (z PRD)
+
+- Preview stabilny i płynny
+- Latencja renderowania niska
+- Dane telemetrii dokładne
+- GUI responsywne
+- Overlay działa poprawnie
+- Architektura gotowa na subskrybentów AI

+Sprint 6:  Faza 5  — OverlayWidget
+Sprint 7:  Faza 6  — MenuBar (camera/resolution/fps switch)
+Sprint 8:  Faza 7  — Testy, poprawki, walidacja na Mac Mini
+```

+
+## Zależności do dodania
+
+```
+# requirements.txt
+PySide6>=6.7
+psutil>=6.0
+
+# requirements-dev.txt
+pytest>=8.0
+ruff>=0.4
+```
+
+---
+
+## Uwagi cross-platform
+
+1. **ELP camera** — kamera UVC, powinna działać bez dodatkowych sterowników na obu platformach. Sprawdzić obsługiwane rozdzielczości i FPS przez `QCameraDevice.videoFormats()`.
+2. **Ścieżki absolutne** — unikać `os.path` na korzyść `pathlib.Path`.
+3. **Threading** — wszystkie operacje Qt muszą odbywać się w wątku GUI. `TelemetryCollector` może używać `QTimer` zamiast osobnego wątku.
+4. **Format klatek** — na macOS AVFoundation preferuje `BGRA` lub `NV12`. Konwersja powinna być leniwa i tylko gdy potrzebna (nie w hot path renderowania).
+5. **High DPI** — włączyć `QApplication.setHighDpiScaleFactorRoundingPolicy` dla konsistencji Windows/Mac.
+6. **Testowanie bez kamery** — `CameraEnumerator` powinien umożliwiać dependency injection / mock dla środowisk CI.

+
+### Opis komponentów
+
+#### CameraEnumerator (`app/camera/camera_enumerator.py`)
+- Wykrywa dostępne kamery przez `QMediaDevices.videoInputs()`
+- Zwraca listę `CameraInfo` z nazwą, id i listą obsługiwanych formatów (rozdzielczość × FPS)
+- Formaty deduplikowane i posortowane (największa rozdzielczość pierwsza)
+- Obsługa braku kamer bez crasha
+
+#### CameraService (`app/camera/camera_service.py`)
+- Opakowuje `QCamera` + `QMediaCaptureSession` + `QVideoSink`
+- API: `start(CameraInfo)`, `stop()`, `reconnect()`, `set_resolution()`, `set_fps()`
+- Algorytm doboru formatu: score-based (priorytet: dopasowanie rozdzielczości, potem FPS)
+- Sygnały: `frame_ready(QVideoFrame)`, `camera_started`, `camera_stopped`, `camera_error`
+
+#### FrameDispatcher (`app/pipeline/frame_dispatcher.py`)
+- Pub/sub: `subscribe(callback, drop_if_busy=True)` / `unsubscribe(callback)`
+- `drop_if_busy=True` — klatka pomijana jeśli subskrybent jest zajęty (render)
+- `drop_if_busy=False` — każda klatka dociera (telemetria)
+- Odporny na wyjątki w subskrybentach (jeden nie blokuje pozostałych)
+
+#### TelemetryCollector (`app/telemetry/telemetry_collector.py`)
+- Subskrybuje każdą klatkę (`drop_if_busy=False`)
+- Mierzy: FPS (okno 1 s), średni frame time (ring-buffer 120 próbek), dropped frames (heurystyka 2.5× avg)
+- CPU: `psutil.Process.cpu_percent()` — tylko nasz proces, inicjalizowany w `__init__` (warmup)
+- RAM: `memory_info().wset` (Windows private working set) lub `rss` (macOS/Linux)
+- Emituje `metrics_updated(TelemetrySnapshot)` co 500 ms przez `QTimer`
+
+#### IOverlayLayer (`app/overlay/overlay_layer.py`)
+- Abstrakcja (ABC) dla pluggable overlayów
+- Interface: `paint(painter: QPainter, video_rect: QRect)`, `visible: bool`, `name: str`
+- Nowe overlaye nie wymagają modyfikacji żadnego istniejącego kodu
+
+#### TelemetryOverlay (`app/overlay/telemetry_overlay.py`)
+- Implementacja `IOverlayLayer`
+- Rysuje semi-przezroczysty box z metrykami w lewym górnym rogu video
+- Slot `on_metrics_updated(TelemetrySnapshot)` — odbiera dane z TelemetryCollector
+- Format: FPS, Frame time, Drop count, CPU %, Mem MB
+
+#### CameraView (`app/ui/camera_view.py`)
+- Zwykły `QWidget` (nie `QVideoWidget`) — render przez `QPainter` w `paintEvent`
+- Odbiera `QVideoFrame` przez slot `on_frame()`, konwertuje do `QImage.Format_RGB32`
+- Letterboxing z zachowaniem aspect ratio
+- Rejestr overlayów: `add_overlay_layer()`, `remove_overlay_layer()`, `set_all_overlays_visible()`
+- W `paintEvent`: rysuje klatkę → iteruje po warstwach, każda dostaje `painter.save()/restore()`
+
+#### MainWindow (`app/ui/main_window.py`)
+- Wires together wszystkie komponenty
+- Minimalny status bar (nazwa kamery, błędy)
+- `closeEvent` → `CameraService.stop()`
+
+#### AppMenuBar (`app/ui/menu_bar.py`)
+- Menu **Camera**: lista wykrytych kamer (radio), Reconnect
+- Menu **Video**: Resolution submenu, FPS submenu (pobierane z `QCameraDevice.videoFormats()`)
+- Menu **Debug**: Show Overlay (toggle), Console Logging (toggle poziom logowania)
+
+---
+
+## Co działało na Windows 11 (dev)
+
+- Wykrycie wbudowanej kamery laptopa
+- Podgląd w czasie rzeczywistym
+- Przełączanie rozdzielczości i FPS z menu
+- Overlay z metrykami widoczny i aktualizowany
+- Toggle overlay przez Debug menu
+- Logowanie do konsoli przez Debug menu
+- Reconnect po zmianie kamery
+- Letterboxing przy resize okna
+
+---
+
+## Co próbowaliśmy i nie wyszło
+
+### QVideoWidget jako renderer (porzucone)
+
+**Podejście:** Użycie `QVideoWidget` jako centralnego widgetu + nałożenie `OverlayWidget` (child lub sibling).
+
+**Problem:** Na Windows `QVideoWidget` tworzy natywne okno HWND z powierzchnią D3D (Media Foundation backend). Natywna powierzchnia jest rysowana poza hierarchią Qt i zawsze przykrywa wszystkie `QWidget` — niezależnie od:
+- kolejności z-order (`raise_()`)
+- rodzica (child/sibling)
+- flag okna
+- `WA_TranslucentBackground` / `WA_NoSystemBackground`
+
+Żaden `QWidget` nie może się wyświetlić nad `QVideoWidget` na Windows.
+
+**Próby ratowania:**
+1. `OverlayWidget` jako child `QVideoWidget` — zasłonięty przez natywną powierzchnię
+2. Kontener `QWidget` z `QVideoWidget` i `OverlayWidget` jako rodzeństwo — nadal zasłonięty
+3. `setWindowFlags(FramelessWindowHint)` na child widget — odrywa widget od rodzica, tworzy osobne (niewidoczne) okno top-level
+
+**Rozwiązanie:** Porzucenie `QVideoWidget`. Własny `CameraView(QWidget)` odbiera klatki przez `QVideoSink`, konwertuje do `QImage` i rysuje przez `QPainter`. Overlay w tym samym `paintEvent` — brak konfliktu z natywnym renderowaniem.
+
+### OverlayWidget jako osobny QWidget (porzucone)
+
+**Podejście:** `OverlayWidget` z `WA_TransparentForMouseEvents` i `WA_TranslucentBackground` nałożony na video.
+
+**Problem:** Poza konfliktem z `QVideoWidget`, `WA_TranslucentBackground` na child widget działa tylko gdy rodzic też jest transparentny — Qt nie komponuje dziecka z tłem rodzica innym niż własne. W praktyce overlay był niewidoczny lub zasłaniał video czarnym prostokątem.
+
+---
+
+## Znane ograniczenia i uwagi
+
+### Pomiar CPU
+
+`psutil.Process.cpu_percent()` zwraca procent **względem jednego rdzenia** (np. 50% = pół rdzenia). Na wielordzeniowym procesorze 15% w Task Managerze (uśrednione po rdzeniach) może odpowiadać 50% na jednym rdzeniu. To nie jest błąd — to różna metodologia. Task Manager pokazuje `total_cpu / num_cores`, psutil pokazuje `cpu_time / wall_time`.
+
+Jeśli potrzebny jest widok "jak Task Manager": `process.cpu_percent() / psutil.cpu_count()`.
+
+### Pomiar RAM
+
+`memory_info().wset` (Windows) = Private Working Set = to co Task Manager pokazuje w kolumnie "Pamięć". RSS zawiera też współdzielone biblioteki (Qt DLLs ~40 MB) i dlatego było zawyżone. Na macOS używane jest `rss` (tam `wset` nie istnieje).
+
+### Wydajność konwersji klatek
+
+`QVideoFrame.toImage()` + `convertToFormat(RGB32)` wykonuje się na CPU. Przy 1080p60 to koszt ~1-3 ms/klatkę. Dla MVP akceptowalny. Przy przyszłej integracji YOLO warto rozważyć bezpośredni dostęp do danych przez `QVideoFrame.map()` i przekazywanie raw bufora do GPU.
+
+### Brak testów integracyjnych
+
+Testy jednostkowe pokrywają `FrameDispatcher` i `TelemetryCollector` w izolacji (bez Qt event loop). Brak testów `CameraView`, `CameraService` i `MainWindow` — wymagałyby `QApplication` i mockowania urządzeń.
+
+---

-1. Przejście z manualnego `QPainter` renderowania na natywny `QVideoWidget`
-2. Dodanie `QVideoSink` jako drugiego wyjścia (frame access dla telemetrii)
-3. Obsługa `QCameraPermission` (Qt 6.5+)
-4. Dokumentacja packagingu przez `pyside6-deploy` na macOS
-
-## Kolejność implementacji
-
-### 1. camera/service.py
-
-```python
-class CameraService(QObject):
-    error_occurred = Signal(str)
-
-    def __init__(self, parent=None):
-        super().__init__(parent)
-        self._session = QMediaCaptureSession()
-        self._camera: QCamera | None = None
-
-    def set_video_widget(self, widget: QVideoWidget) -> None:
-        self._session.setVideoOutput(widget)
-
-    def set_video_sink(self, sink: QVideoSink) -> None:
-        self._session.setVideoSink(sink)
-
-    @property
-    def session(self) -> QMediaCaptureSession:
-        return self._session
-
-    @staticmethod
-    def available_cameras() -> list[QCameraDevice]:
-        return QMediaDevices.videoInputs()
-
-    def is_active(self) -> bool:
-        return self._camera is not None and self._camera.isActive()
-
-    def start(self, device: QCameraDevice) -> None:
-        self.stop()
-        self._camera = QCamera(device, self)
-        self._camera.errorOccurred.connect(self._on_error)
-        self._session.setCamera(self._camera)
-        self._camera.start()
-
-    def stop(self) -> None:
-        if self._camera is not None:
-            self._camera.stop()
-            self._session.setCamera(None)
-            self._camera.deleteLater()
-            self._camera = None
-
-    def set_camera_format(self, fmt: QCameraFormat) -> None:
-        if self._camera is not None:
-            self._camera.setCameraFormat(fmt)
-
-    def _on_error(self, error, error_string):
-        self.error_occurred.emit(error_string)
-```
-
-Zmiany:
-- Usunięto `self._sink` z `__init__`
-- Usunięto `self._session.setVideoOutput(self._sink)`
-- Dodano `set_video_widget(widget)` → `session.setVideoOutput(widget)`
-- Dodano `set_video_sink(sink)` → `session.setVideoSink(sink)`
-
-### 2. rendering/video_widget.py
-
-```python
-from __future__ import annotations
-
-from PySide6.QtMultimediaWidgets import QVideoWidget
-
-
-class VideoWidget(QVideoWidget):
-    def __init__(self, parent=None):
-        super().__init__(parent)
-        self.setMinimumSize(320, 240)
-```
-
-Zmiany:
-- Dziedziczy po `QVideoWidget` zamiast `QWidget`
-- Usunięto `on_frame(frame)` — nie potrzeba, renderowanie natywne
-- Usunięto `paintEvent` — nie potrzeba, robi to Qt
-- Usunięto `QImage`, `QPainter`, `SmoothPixmapTransform`
-
-### 3. rendering/overlay.py
-
-```python
-font = QFont("monospace", 11)  # zamiast "Consolas"
-```
-
-Dodatkowo: obsługa błędu w `paintEvent`:
-- Jeśli `self._metrics` ma klucz `"error"` → pomiń normalne metryki, narysuj czerwony komunikat błędu
-- Użyj `QColor(180, 40, 40)` zamiast zielonego
-
-### 4. app.py — nowe DI wiring
-
-```python
-def main():
-    app = QApplication(sys.argv)
-    app.setApplicationName("Duck Preview")
-
-    camera = CameraService()
-    video_sink = QVideoSink()
-    dispatcher = FrameDispatcher()
-    telemetry = TelemetryCollector()
-    video_widget = VideoWidget()
-    overlay = OverlayWidget()
-
-    camera.set_video_widget(video_widget)
-    camera.set_video_sink(video_sink)
-
-    video_sink.videoFrameChanged.connect(dispatcher.on_frame)
-    dispatcher.subscribe(telemetry.on_frame)
-
-    window = MainWindow(camera, video_widget, overlay)
-
-    # Wire error → overlay
-    camera.error_occurred.connect(
-        lambda msg: overlay.set_metrics({"error": msg})
-    )
-
-    # Poll telemetry → overlay
-    metrics_timer = QTimer()
-    metrics_timer.timeout.connect(
-        lambda: overlay.set_metrics(telemetry.metrics())
-    )
-    metrics_timer.start(200)
-
-    window.show()
-    sys.exit(app.exec())
-```
-
-Zmiany:
-- Tworzy `QVideoSink` jawnie
-- `camera.set_video_widget(video_widget)` + `camera.set_video_sink(video_sink)`
-- `video_sink.videoFrameChanged → dispatcher.on_frame`
-- Usunięto `camera.sink` (property nie istnieje)
-- `camera.error_occurred → overlay.set_metrics({"error": msg})`
-
-### 5. main_window.py — permission flow
-
-```python
-# Importy
-from PySide6.QtCore import QCameraPermission, Qt
-from PySide6.QtWidgets import QApplication
-
-# W _on_camera_selected:
-def _on_camera_selected(self, device: QCameraDevice) -> None:

-        case Qt.PermissionStatus.Granted:
-            self._camera.start(device)
-            self._rebuild_resolution_menu(device)

-# macOS — Camera on macOS with PySide6
-
-## Problem
-
-Aplikacja uruchomiona w interpreted mode (`python -m duck_preview`) na macOS z kamerą Elgato nie wyświetla obrazu.
-
-## Przyczyna
-
-Oficjalny przykład PySide6 (`camera.qml` / examples/multimedia) zawiera kod:
-
-```python
-if sys.platform == "darwin":
-    is_nuitka = "__compiled__" in globals()
-    if not is_nuitka and sys.platform == "darwin":
-        print("This example does not work on macOS when Python is run "
-              "in interpreted mode. For this example to work on macOS, "
-              "package the example using pyside6-deploy")
-        sys.exit(0)
-```
-
-**macOS → AVFoundation → wymaga spakowania przez Nuitka/pyside6-deploy.**
-
-`QCamera` na macOS potrzebuje properly bundled app structure (Info.plist, entitlements, code signing). W interpreted mode Python nie ma tego contextu.
-
-## Rozwiązanie
-
-Pakować aplikację przez `pyside6-deploy` (Nuitka) na macOS. Na Windows działa bez pakowania.
-
----
-
-## Qt Permission API (`QCameraPermission`)
-
-Od Qt 6.5+ dostępne jest `QCameraPermission` — nowoczesne API do proszenia o zgodę kamery.
-
-### API
-
-```python
-from PySide6.QtCore import QCameraPermission, Qt
-from PySide6.QtWidgets import QApplication
-
-perm = QCameraPermission()
-match QApplication.checkPermission(perm):
-    case Qt.PermissionStatus.Undetermined:
-        # Prosimy o zgodę → callback wywoła init ponownie
-        QApplication.requestPermission(perm, parent, callback)
-        return
-    case Qt.PermissionStatus.Denied:
-        # overlay: "Camera permission denied"
-    case Qt.PermissionStatus.Granted:
-        # uruchom kamerę
-```
-
-### Permission flow
-
-```
-User → wybiera kamerę w menu
-  → MainWindow._on_camera_selected(device)
-    → checkPermission(QCameraPermission)
-      ├─ Undetermined → requestPermission(camera, parent, callback)
-      │                   └─ callback → _on_camera_selected ponownie
-      ├─ Denied → overlay: "Camera permission denied. Grant access in System Settings > Privacy & Security > Camera"
-      └─ Granted → CameraService.start(device)
-```
-
----
-
-## QVideoWidget + QVideoSink — dual output
-
-PySide6 6.11 ma osobne metody w `QMediaCaptureSession`:
-
-| Metoda | Przeznaczenie |
-|--------|---------------|
-| `setVideoOutput(QVideoWidget*)` | Natywne renderowanie (GPU) |
-| `setVideoSink(QVideoSink*)` | Dostęp do klatek (telemetria, AI) |
-
-Oba działają **równolegle** — nie ma konfliktu.
-
-```
-QMediaCaptureSession
-  ├─ setVideoOutput(QVideoWidget)  → natywne renderowanie
-  └─ setVideoSink(QVideoSink)      → frame access
-                                       └─ videoFrameChanged → FrameDispatcher
-```
-
-QVideoSink dostarcza sygnał `videoFrameChanged(QVideoFrame)` — na to podpina się FrameDispatcher, a ten rozsyła do TelemetryCollector i przyszłych AI subscriberów.
-
----
-
-## macOS — packaging
-
-### pyside6-deploy
-
-```bash
-pip install nuitka
-pyside6-deploy duck_preview/__main__.py --name "Duck Preview"
-```
-
-### pyside6-deploy.toml
-
-```toml
-[app]
-script = "duck_preview/__main__.py"
-name = "Duck Preview"
-bundle_identifier = "com.bartool.duck-preview"
-categories = "public.app-category.photography"
-platforms = ["macos"]
-```
-
-Po spakowaniu powstaje `Duck Preview.app` — standalone bundle z dostępem do AVFoundation.
-
-### Windows
-
-Na Windows działa bez pakowania — `python -m duck_preview` w venv.
-
----
-
-## Font fallback
-
-`Consolas` nie istnieje na macOS. Używać `"monospace"` (generic font family — Qt mapuje na Menlo na macOS, Consolas na Windows).
-
-## Error state w Overlay
-
-Overlay wspiera wyświetlanie błędów (np. brak permisji):
-- Normalny stan → zielone metryki (FPS, frame times)
-- Error state → czerwony komunikat
-- Przełączanie przez `overlay.set_metrics({"error": "message"})`

+# Goal
+
+Zbudować aplikację do podglądu kamery w czasie rzeczywistym (PySide6) z telemetrią, overlayami i systemem logowania do pliku — docelowo na Mac Mini z kamerą ELP.
+
+---
+
+# Constraints & Preferences

+- Python 3.12.10, venv w `.venv-win`
+- Dev: Windows 11
+- Target: Mac Mini Intel i7, macOS Ventura, kamera ELP USB
+- `PySide6 6.11.0`, `psutil`, `pytest`, `ruff`

+- Logi:
+  - `logs/` w katalogu projektu
+  - nowy plik z timestamp per sesja
+  - max 20 plików
+- CSV telemetrii:
+  - co 5 sekund
+  - `flush` po każdym wierszu
+- CPU:
+  - pokazywać oba:
+    - sys %
+    - per-core % (jak Task Manager)
+- Zmiana formatu kamery przez `stop+start`
+  - nie `setCameraFormat` na żywej kamerze

+# Key Decisions
+
+## Rendering
+
+### `QVideoWidget` → własny `CameraView(QWidget)`
+
+Jedyny skuteczny sposób obejścia problemu z natywnym HWND na Windows.
+
+## Overlay Architecture
+
+### `IOverlayLayer` ABC
+
+Pluggable overlaye bez modyfikacji `CameraView`.
+
+Gotowe pod:
+
+- YOLO
+- OCR
+- inne overlaye
+
+## Pipeline
+
+### `FrameDispatcher`
+
+Pub/sub z `drop_if_busy`:
+
+- render może gubić klatki
+- telemetria nigdy
+
+## CPU Metrics
+
+- CPU per-core (`psutil`)
+- dzielone przez `cpu_count`
+- wynik zgodny z Task Manager
+
+## Memory Metrics
+
+- `memory_info().wset` (Windows)
+- zamiast `rss`
+- odpowiada `Private Working Set`
+
+## Logging Strategy
+
+Dwa osobne pliki per sesja:
+
+- `.log` — diagnostyka
+- `.csv` — metryki szeregów czasowych
+
+## CameraFormat
+
+`CameraFormat` dataclass zamiast krotki:
+
+- niesie `pixel_format`
+- potrzebny w logach
+
+---
+
+# Next Steps
+
+1. Przetestować na Windows:
+   - czy logi powstają w `logs/`
+   - czy CSV zapisuje dane co ~5 s
+
+2. Przenieść na Mac Mini i przetestować z kamerą ELP:
+   - sprawdzić `pixel_format` w logu
+   - sprawdzić wykrycie backendu AVFoundation
+
+3. Zweryfikować overlay telemetrii na żywym obrazie
+
+4. (Opcjonalnie) dodać kolejne `IOverlayLayer`
+   - YOLO
+   - OCR

+```
+
+`menu_bar.py` i `camera_service.py` iterują po:
+
+- `fmt.width`
+- `fmt.height`
+- `fmt.max_fps`
+

+## CSV Logger
+
+Ścieżka CSV:

+
+Powstaje para:

+- `.log`
+- `.csv`
+
+z tym samym timestamp.

+# Stan projektu po sesji: UVC controls + przebudowa menu formatu
+
+## Kontekst
+
+Aplikacja uruchomiona na docelowym Mac Mini. Kamera ELP dostarcza klatki w formacie NV12 (przez backend AVFoundation). Stare menu z osobnymi podmenu `Resolution` i `FPS` nie nadawało się do użycia — kamera eksponuje formaty jako kombinacje (rozdzielczość + fps + pixel format), a ich niezależne ustawianie dawało nieskoordynowane wyniki.
+
+Dodano też interfejs do kontroli parametrów obrazu kamery.
+
+---
+
+## Zmiany w tej sesji
+
+### 1. Menu formatu — przebudowane (`app/ui/menu_bar.py`)
+
+**Przed:** dwa osobne podmenu — `Video → Resolution` i `Video → FPS`.
+
+**Po:** jedno podmenu `Video → Resolution` z pozycjami reprezentującymi pełny format:
+
+```
+1920×1080 @ 30fps (NV12)
+1920×1080 @ 30fps (MJPG)
+1280×720 @ 30fps (NV12)
+1280×720 @ 5fps (YUY2)
+640×480 @ 30fps (MJPG)
+...
+```
+
+Każda pozycja odpowiada dokładnie jednemu `CameraFormat` z `CameraInfo.formats`. Kolejność odzwierciedla sortowanie z `CameraEnumerator` (największa powierzchnia → najwyższe fps).
+
+**Sygnały:**
+
+- Usunięto: `resolution_selected(int, int)`, `fps_selected(float)`
+- Dodano: `format_selected(CameraFormat)` — emituje pełny obiekt formatu
+- Dodano: `camera_settings_requested()` — otwiera dialog ustawień
+
+**Metody publiczne:**
+
+- `populate_formats(camera_info)` — zamiast `populate_resolutions` + `populate_fps`
+- `set_active_format(fmt)` — zaznacza aktywny format po zmianie (matching po w/h/fps/pixel_format)
+- Usunięto: `set_console_level()` (przeniesione do wewnętrznego `_on_log_toggled`)
+
+**Nowe menu `Image`:**
+
+```
+Image
+  └── Camera Settings…   → otwiera CameraSettingsDialog
+```
+
+---
+
+### 2. CameraService — `set_format()` (`app/camera/camera_service.py`)
+
+**Przed:** dwie metody `set_resolution(w, h)` i `set_fps(fps)` przechowujące `_desired_width`, `_desired_height`, `_desired_fps` osobno.
+
+**Po:** jedna metoda `set_format(fmt: CameraFormat)` przechowująca `_desired_fmt: CameraFormat | None`.
+
+```python
+def set_format(self, fmt: CameraFormat) -> None:
+    self._desired_fmt = fmt
+    if self._current_info is not None:
+        self.start(self._current_info)   # stop+start jak poprzednio
+```
+
+**Scoring przy wyborze formatu Qt (`_apply_format`):**
+
+Poprzednio scoringował tylko rozdzielczość i fps. Teraz uwzględnia też pixel format:
+
+```python
+exact_res  = int(w == desired.width and h == desired.height) * 1000
+exact_pf   = int(pf == desired.pixel_format) * 500
+exact_fps  = int(abs(f - desired.max_fps) < 0.5) * 100
+area_diff  = abs(w * h - desired.width * desired.height)
+score      = exact_res + exact_pf + exact_fps - area_diff
+```
+
+Pixel format jest drugim co do ważności kryterium (po rozdzielczości, przed fps).
+
+**Nowa właściwość:**
+
+```python
+@property
+def qt_camera(self) -> QCamera | None:
+    ...
+```
+
+Udostępnia wewnętrzny `QCamera` dla `CameraSettingsDialog` (potrzebny do ustawiania WB i exposure przez Qt API).
+
+**Poprawione logowanie:**
+
+`_log_actual_format()` loguje teraz ostrzeżenia zarówno dla FPS jak i rozdzielczości jeśli kamera nie dostarczyła tego co było żądane.
+
+---
+
+### 3. Warstwa UVC (`app/camera/uvc/`)
+
+Nowy pakiet z abstrakcją dla sterowania parametrami obrazu przez UVC (USB Video Class).
+
+#### Dlaczego osobna warstwa, nie Qt?
+
+`QCamera.Feature` w Qt6 obejmuje: `ColorTemperature`, `ExposureCompensation`, `IsoSensitivity`, `ManualExposureTime`, `CustomFocusPoint`, `FocusDistance`. **Nie obejmuje** brightness, contrast, saturation, hue, sharpness, gamma, backlight compensation — są to niskopoziomowe UVC/V4L2 controls poza zakresem Qt Multimedia.
+
+Sterowanie nimi wymaga osobnych bibliotek natywnych, innych na każdej platformie.
+
+#### Dostępne biblioteki
+
+| Biblioteka | Platforma | Instalacja | Uwagi |
+|---|---|---|---|
+| `duvc-ctl` | Windows only | `pip install duvc-ctl` | DirectShow, stabilna, PyPI, MIT |
+| `pyuvc` | macOS + Linux | `brew install libusb jpeg-turbo && pip install pyuvc` | libuvc bindings, wymaga kompilacji |
+| `uvc-py` | macOS + Linux (Win w planie) | `pip install uvc-py` | dev/alpha, brak UVC controls |
+
+#### Struktura
+
+```
+app/camera/uvc/
+├── __init__.py      # make_uvc_controller(name) — factory z detekcją platformy
+├── base.py          # UvcControllerBase ABC, UvcParam enum, UvcParamInfo dataclass
+├── stub.py          # NullUvcController — no-op fallback
+├── windows.py       # WindowsUvcController — duvc-ctl (DirectShow)
+└── macos.py         # MacUvcController — pyuvc (libuvc)
+```
+
+#### `UvcParam` enum
+
+```python
+class UvcParam(Enum):
+    BRIGHTNESS
+    CONTRAST
+    SATURATION
+    HUE
+    SHARPNESS
+    GAMMA
+    WHITE_BALANCE
+    BACKLIGHT_COMPENSATION
+    EXPOSURE
+```
+
+#### `UvcParamInfo` dataclass
+
+```python
+@dataclass
+class UvcParamInfo:
+    param: UvcParam
+    supported: bool
+    minimum: int = 0
+    maximum: int = 100
+    default: int = 50
+    current: int = 50
+    step: int = 1
+    auto_supported: bool = False
+    auto_enabled: bool = False
+```
+
+#### `UvcControllerBase` ABC — interfejs
+
+```python
+def open(self, device_name: str) -> bool     # otwiera uchwyt do urządzenia
+def close(self) -> None
+def is_open(self) -> bool
+def get_param_info(self, param: UvcParam) -> UvcParamInfo
+def get_all_params(self) -> list[UvcParamInfo]
+def set_value(self, param: UvcParam, value: int) -> bool
+def set_auto(self, param: UvcParam, enabled: bool) -> bool
+```
+
+#### `make_uvc_controller(device_name)` — factory
+
+Detekcja platformy w runtime:
+
+```python
+if system == "Windows":
+    → WindowsUvcController (duvc-ctl)
+elif system == "Darwin":
+    → MacUvcController (pyuvc)
+else:
+    → NullUvcController
+```
+
+Jeśli biblioteka nie jest zainstalowana — `ImportError` przechwycony, fallback na `NullUvcController`. Loguje `WARNING` z instrukcją instalacji.
+
+#### `WindowsUvcController` — szczegóły
+
+- Łączy się z pierwszym urządzeniem którego nazwa zawiera `device_name` (case-insensitive)
+- Mapowanie `UvcParam → duvc-ctl VidProp/CamProp` string:
+  - `BRIGHTNESS → "brightness"`, `CONTRAST → "contrast"`, ..., `EXPOSURE → "exposure"`
+- `set_auto()` używa `duvc.CamMode.AUTO/MANUAL`
+- `_refresh_supported()` odpytuje `cam.get_supported_properties()` po otwarciu
+
+#### `MacUvcController` — szczegóły
+
+- Używa `uvc.device_list()` do wyszukania urządzenia po nazwie
+- Otwiera przez `uvc.Capture(uid)`
+- Mapowanie `UvcParam → pyuvc display_name` string:
+  - `WHITE_BALANCE → "White Balance temperature"`, `EXPOSURE → "Absolute Exposure Time"`, itd.
+- `auto_mode` via `ctrl.auto_mode` (atrybut pyuvc control)
+
+---
+
+### 4. CameraSettingsDialog (`app/ui/camera_settings_dialog.py`)
+
+`QDialog` ze scrollowaną zawartością, dwoma sekcjami. Zmiany aplikowane **na żywo** (brak OK/Apply — tylko Close).
+
+#### Sekcja Qt Camera Controls
+
+| Kontrolka | Widget | Akcja |
+|---|---|---|
+| White Balance | `QComboBox` (8 trybów + Manual) | `camera.setWhiteBalanceMode()` |
+| Colour Temp (K) | `QSpinBox` 2000–10000, krok 100 | `camera.setColorTemperature()` — widoczny tylko w trybie Manual |
+| Exposure Mode | `QComboBox` (Auto / Manual) | `camera.setExposureMode()` |
+| Exposure Time (s) | `QDoubleSpinBox`, 6 miejsc po przecinku | `camera.setManualExposureTime()` — widoczny tylko w trybie Manual |
+
+Dynamiczna widoczność: pola `Colour Temp` i `Exposure Time` pojawiają się tylko gdy wybrano tryb Manual.
+
+Tryby WB sprawdzane przez `camera.isWhiteBalanceModeSupported()` przed aplikacją — jeśli kamera nie obsługuje trybu, zmiana jest ignorowana (logowane DEBUG).
+
+#### Sekcja UVC Camera Controls
+
+Dla każdego `UvcParam`:
+
+- Jeśli `supported=False`: wyświetla "Not supported" (disabled)
+- Jeśli `supported=True`: `QSlider` + `QSpinBox` zsynchronizowane dwukierunkowo
+- Jeśli `auto_supported=True`: dodatkowy `QCheckBox "Auto"` — po zaznaczeniu blokuje slider i spinbox
+
+Jeśli `NullUvcController` (żadne kontrolki nieobsługiwane): sekcja wyświetla notatkę:
+
+```
+UVC controls not available.
+Install duvc-ctl (Windows) or pyuvc (macOS) to enable.
+```
+
+---
+
+### 5. MainWindow — aktualizacje (`app/ui/main_window.py`)
+
+**Nowe pola:**
+
+```python
+self._uvc: UvcControllerBase = NullUvcController()
+```
+
+**Nowe metody:**
+
+- `_open_uvc(cam)` — zamyka poprzedni UVC controller i otwiera nowy dla wybranej kamery
+- `_on_format_selected(fmt)` → `camera_service.set_format(fmt)`
+- `_on_settings_requested()` → tworzy `CameraSettingsDialog(qt_camera, uvc)` i wywołuje `.exec()`
+
+**Zmiany w `_wire_signals()`:**
+
+- Usunięto: `menu.resolution_selected`, `menu.fps_selected`
+- Dodano: `menu.format_selected → _on_format_selected`
+- Dodano: `menu.camera_settings_requested → _on_settings_requested`
+
+**`closeEvent`:**
+
+- Dodano: `self._uvc.close()` jeśli `is_open()`
+
+---
+
+### 6. Testy (`tests/test_uvc.py`) — nowy plik, 15 testów
+
+| Klasa testowa | Co testuje |
+|---|---|
+| `TestNullUvcController` | `open` → False, `is_open` → False, `close` bez wyjątku, `get_param_info` → unsupported, `get_all_params` zwraca wszystkie `UvcParam`, `set_value`/`set_auto` → False bez wyjątku |
+| `TestUvcParamInfo` | wartości domyślne dataclass, flaga `supported=False`, custom range |
+| `TestMakeUvcControllerFallback` | zwraca instancję `UvcControllerBase`, fallback na stub gdy `ImportError` |
+
+Łącznie testów: **35** (20 poprzednich + 15 nowych), wszystkie zielone.
+
+---
+
+## Decyzje architektoniczne
+
+### Dlaczego `set_format()` zamiast osobnych `set_resolution`/`set_fps`?
+
+Kamera ELP przez AVFoundation eksponuje formaty jako niepodzielne kombinacje `(W × H, fps, pixel_format)`. Próba niezależnej zmiany rozdzielczości bez zmiany fps (i odwrotnie) prowadziła do niespójnych stanów — kamera ignorowała jedną z wartości albo wybierała domyślny format. Jeden `CameraFormat` jako atomowa jednostka wyboru eliminuje problem.
+
+### Dlaczego warstwowa architektura UVC a nie jedna biblioteka?
+
+Brak cross-platform biblioteki Python dla UVC controls. `duvc-ctl` — Windows only (DirectShow), `pyuvc` — macOS/Linux (libuvc). Warstwa abstrakcji z platformową detekcją w runtime pozwala:
+- Działać bez żadnej biblioteki (NullUvcController — grayed-out w UI)
+- Dodać obsługę nowej platformy bez zmiany warstwy wyżej
+- Testować logikę UI niezależnie od dostępności sprzętu
+
+### Dlaczego Qt controls i UVC controls w jednym dialogu?
+
+WB i exposure są dostępne przez oba API (Qt i UVC). Qt API jest wyżej poziomowe (tryby, EV), UVC daje surowe wartości rejestrów. Użytkownik widzi jedno spójne miejsce — nie musi wiedzieć przez które API co działa.
+
+---
+
+## Pliki zmienione / dodane
+
+### Zmienione
+
+| Plik | Co zmieniono |
+|---|---|
+| `app/ui/menu_bar.py` | Przebudowa menu: `format_selected` zamiast `resolution_selected`+`fps_selected`, nowe menu Image |
+| `app/camera/camera_service.py` | `set_format()` zamiast `set_resolution`/`set_fps`, `qt_camera` property, lepsza walidacja w `_log_actual_format` |
+| `app/ui/main_window.py` | UVC lifecycle, nowe sygnały menu, `_on_settings_requested` |
+
+### Dodane
+
+| Plik | Co zawiera |
+|---|---|
+| `app/camera/uvc/__init__.py` | `make_uvc_controller()` factory |
+| `app/camera/uvc/base.py` | `UvcControllerBase`, `UvcParam`, `UvcParamInfo` |
+| `app/camera/uvc/stub.py` | `NullUvcController` |
+| `app/camera/uvc/windows.py` | `WindowsUvcController` (duvc-ctl) |
+| `app/camera/uvc/macos.py` | `MacUvcController` (pyuvc) |
+| `app/ui/camera_settings_dialog.py` | `CameraSettingsDialog` |
+| `tests/test_uvc.py` | 15 testów UVC layer |
+
+---
+
+## Instalacja bibliotek UVC
+
+### Mac Mini (cel docelowy)
+
+```bash
+brew install libusb jpeg-turbo
+pip install pyuvc
+```
+
+### Windows (dev)
+
+```bash
+pip install duvc-ctl
+```
+
+### Bez bibliotek
+
+Aplikacja działa normalnie — sekcja UVC w `CameraSettingsDialog` wyświetla komunikat o braku biblioteki. Qt controls (WB, Exposure) działają niezależnie od UVC.
+
+---
+
+## Next Steps
+
+1. Przetestować na Mac Mini z kamerą ELP:
+   - czy `MacUvcController` otwiera urządzenie po `pip install pyuvc`
+   - czy slidery zmieniają rzeczywiste parametry kamery
+   - czy `Camera Settings…` poprawnie pokazuje zakresy dla ELP (np. brightness 0–255)
+
+2. Sprawdzić czy AVFoundation na macOS honoruje `setCameraFormat` bez stop+start (Qt docs mówią że na macOS inny proces może nadpisać format — `_log_actual_format` oznaczy to jako warning)
+
+3. Dodać `set_active_format()` call po `_log_actual_format()` żeby menu zaznaczało faktycznie działający format (nie żądany)
+
+4. Rozważyć `QSlider` z etykietą wartości min/max/default w dialogu — aktualnie są tylko slider + spinbox
+
+5. (Opcjonalnie) Preset systemu: zapisz/wczytaj ustawienia do JSON per kamera
+
+---
+
+## Critical Context
+
+- `CameraService.qt_camera` → `QCamera | None` — potrzebny do `CameraSettingsDialog`, jest `None` gdy kamera zatrzymana
+- `make_uvc_controller(name)` zwraca **już otwarty lub próbujący otworzyć** kontroler; `MainWindow._open_uvc()` nie wywołuje `.open()` ponownie jeśli `is_open()` zwróci True
+- `MacUvcController` używa `uvc.device_list()` (pyuvc API) — wymaga że kamera **nie jest** aktywnie używana przez inny proces (ograniczenie libusb na macOS)
+- `WindowsUvcController` działa **równolegle** z Qt — DirectShow pozwala na jednoczesny dostęp do controls i streamu
+- Testy UVC nie wymagają sprzętu ani bibliotek natywnych — `NullUvcController` jest czystym Pythonem
+
+## Uruchamianie
+
+```bash
+# Windows dev
+.venv-win\Scripts\python.exe -m app.main
+
+# Mac Mini (po instalacji pyuvc)

+# Stan projektu po sesji: YOLO inference + odtwarzanie wideo
+
+Poprzedni stan: `04-mvp-uvc.md`
+
+---
+
+## Kontekst
+
+Po uruchomieniu aplikacji na Mac Mini z kamerą ELP, kolejny krok to weryfikacja
+wytrenowanego modelu YOLO. Wymagania:
+
+- Model działa w **osobnym procesie** — crash workera nie wywala GUI
+- Inference **nie blokuje** i **nie spowalnia** podglądu kamery
+- Worker **ignoruje klatki** dopóki analizuje poprzednią (drop-if-busy)
+- Możliwość wczytania **pliku wideo** zamiast kamery do oceny modelu
+- Bbox narysowany na nowej **warstwie overlay**
+- W przyszłości OCR będzie działał w tym samym procesie co YOLO

+## Nowe pakiety
+
+### `app/video/`
+
+```
+app/video/
+├── __init__.py
+└── video_player.py
+```
+
+### `app/inference/`
+
+```
+app/inference/
+├── __init__.py
+├── worker.py           # funkcja uruchamiana w subprocess
+├── worker_manager.py   # InferenceManager (QObject) — IPC, polling, auto-restart
+└── bbox_overlay.py     # BboxOverlay(IOverlayLayer) — rysuje bbox+label+conf
+```
+
+---
+
+## Szczegółowy opis zmian
+
+### 1. `app/video/video_player.py` — `VideoPlayer`
+
+Nowa klasa `VideoPlayer(QObject)` — identyczny interfejs sygnałowy jak `CameraService`:
+
+```python
+frame_ready     = Signal(QVideoFrame)
+playback_started = Signal()
+playback_stopped = Signal()
+playback_error   = Signal(str)
+```
+
+Wewnętrznie: `QMediaPlayer` + `QVideoSink`. Obsługuje formaty: `.mp4`, `.avi`,
+`.mov`, `.mkv`, `.m4v`, `.webm` (cokolwiek obsługuje FFmpeg backend Qt).
+
+Odtwarzanie w czasie rzeczywistym (1×). Brak seek/pauzy — tylko Open + Stop.
+
+`MainWindow` podłącza do `FrameDispatcher` albo `CameraService.frame_ready`,
+albo `VideoPlayer.frame_ready` — nigdy obu naraz. Przełączanie przez
+`_switch_to_camera()` / `_switch_to_video()`.
+
+---
+
+### 2. `app/inference/worker.py` — worker process
+
+#### Struktury IPC (NamedTuple — pickle-safe)
+
+```python
+class FramePacket(NamedTuple):
+    frame_id: int
+    raw_bytes: bytes    # RGB, (H×W×3)
+    width: int
+    height: int
+    channels: int       # zawsze 3
+
+class WorkerReadyPacket(NamedTuple):
+    device: str         # "cpu" | "mps" — wysyłany raz po załadowaniu modelu
+
+class ResultPacket(NamedTuple):
+    frame_id: int
+    detections: list    # list of (x1, y1, x2, y2, conf, label)
+    width: int
+    height: int
+    elapsed_ms: float   # czas wywołania model() w ms
+```
+
+#### Protokół IPC
+
+```
+input_queue  ← FramePacket
+output_queue → WorkerReadyPacket  (raz, zaraz po załadowaniu modelu)
+             → ResultPacket       (po każdej analizowanej klatce)
+             → None               (tylko przy błędzie ładowania modelu)
+```
+
+#### `_select_device()` — wybór urządzenia
+
+Wywoływany **raz przy starcie workera** (nie per-frame jak wcześniej):
+
+```python
+def _select_device() -> str:
+    if platform.system() == "Darwin":
+        if torch.backends.mps.is_available():
+            return "mps"   # Metal GPU na macOS
+    return "cpu"
+```
+
+`device` jest przekazywany do `_load_model()` i do każdego wywołania `_infer()`.
+Eliminuje redundantne wykrywanie urządzenia przy każdej klatce.
+
+#### `_infer()` — pomiar czasu
+
+```python
+t0 = time.perf_counter()
+results = model(frame_np, device=device, verbose=False)
+elapsed_ms = (time.perf_counter() - t0) * 1000.0
+```
+
+`elapsed_ms` trafia do `ResultPacket` i jest logowany w managerze przy detekcjach.
+
+---
+
+### 3. `app/inference/worker_manager.py` — `InferenceManager`
+
+#### Sygnały
+
+```python
+detections_ready      = Signal(object, object)  # list[Detection], tuple[int,int]
+detection_count_updated = Signal(int)           # łączna liczba klatek z detekcją
+inference_stats_updated = Signal(str, float)    # device, avg_elapsed_ms
+inference_device_changed = Signal(str)          # emitowany raz po WorkerReadyPacket
+inference_started     = Signal()
+inference_stopped     = Signal()
+inference_error       = Signal(str)
+```
+
+#### Mechanizm drop-if-busy
+
+```python
+def submit_frame(self, frame: QVideoFrame) -> None:
+    if not self.is_running or self._paused or self._busy:
+        return   # klatka odrzucona cicho
+    # konwersja + put_nowait → self._busy = True
+```
+
+`self._busy` wraca do `False` dopiero gdy `_poll_output()` odbierze `ResultPacket`.
+Gwarantuje że nigdy nie ma więcej niż jedna klatka w locie.
+
+#### Konwersja klatki w GUI thread
+
+Zamiast `frame.bits(0)` (dawało tylko płaszczyznę Y dla NV12):
+
+```python
+image = frame.toImage()                           # Qt dekoduje NV12/YUV/MJPG → RGB
+image = image.convertToFormat(Format_RGB32)       # packed BGRX
+arr = np.frombuffer(image.bits(), dtype=np.uint8).reshape((H, W, 4))
+rgb = arr[:, :, [2, 1, 0]].copy()                # BGRX → RGB, drop X
+```
+
+Obsługuje każdy pixel format jaki kamera może dostarczyć.
+
+#### Rolling average elapsed_ms
+
+```python
+_elapsed_window: deque[float]  # maxlen=10
+avg_ms = sum(_elapsed_window) / len(_elapsed_window)
+```
+
+Emitowany przez `inference_stats_updated(device, avg_ms)` po każdym `ResultPacket`.
+
+#### `_poll_output()` — obsługa `WorkerReadyPacket`
+
+```python
+if isinstance(item, WorkerReadyPacket):
+    self._current_device = item.device
+    self.inference_device_changed.emit(item.device)
+    continue
+```
+
+Odróżnienie od `ResultPacket` przez `isinstance` — nie wymaga sentinel wartości.
+
+#### Auto-restart
+
+- Watchdog co 2s sprawdza `process.is_alive()`
+- Timeout 10s bez odpowiedzi → terminate + restart
+- Max 3 restartów (konfigurowalny przez `INFERENCE_MAX_RESTARTS`)
+- Po przekroczeniu: `QMessageBox.critical` + overlay wyłączony
+
+#### Logowanie — tylko detekcje
+
+```python
+if detections:
+    logger.info(
+        "frame %d: %d detection(s) in %.1f ms — %s",
+        packet.frame_id, len(detections), packet.elapsed_ms, conf_summary,
+    )
+```
+
+Klatki bez detekcji: brak logu. `conf_summary = "label 0.94, label 0.81"`.
+
+---
+
+### 4. `app/inference/bbox_overlay.py` — `BboxOverlay`
+
+```python
+class Detection(NamedTuple):
+    x1: float; y1: float; x2: float; y2: float
+    conf: float
+    label: str
+```
+
+Współrzędne w pikselach **oryginalnej klatki**. `paint()` skaluje do `video_rect`:
+
+```python
+scale_x = video_rect.width() / src_w
+scale_y = video_rect.height() / src_h
+wx1 = video_rect.x() + int(det.x1 * scale_x)
+# ...
+```
+
+Każdy bbox: prostokąt w kolorze `BBOX_COLOR` + label `"label 0.87"` na tle
+`BBOX_LABEL_BG_COLOR` nad lewym górnym rogiem boxa (lub wewnątrz gdy brakuje miejsca).
+
+`BboxOverlay.visible = False` domyślnie — pojawia się dopiero po włączeniu inference toggle.
+
+---
+
+### 5. Menu — zmiany w `app/ui/menu_bar.py`
+
+Dodano dwa nowe menu przed istniejącymi:
+
+```
+File
+  ├── Open Video…         QFileDialog (.mp4 .avi .mov .mkv .m4v .webm)
+  └── Close Video         disabled gdy źródło = kamera
+
+Model
+  ├── Load Model…         QFileDialog (.pt .pth)
+  ├── Enable Inference    QAction checkable, disabled do momentu załadowania modelu
+  └── Model: (none)       disabled — info o załadowanym pliku
+```
+
+Nowe sygnały:
+- `video_file_selected(str)` — ścieżka pliku wideo
+- `video_closed()` — powrót do kamery
+- `model_file_selected(str)` — ścieżka modelu
+- `inference_toggled(bool)` — włącz/wyłącz inference
+
+---
+
+### 6. `app/ui/main_window.py` — integracja
+
+#### Przełączanie źródła klatek
+
+```python
+def _switch_to_camera(self):
+    video_player.frame_ready.disconnect(dispatcher.dispatch)
+    camera_service.frame_ready.connect(dispatcher.dispatch)
+
+def _switch_to_video(self):
+    camera_service.frame_ready.disconnect(dispatcher.dispatch)
+    video_player.frame_ready.connect(dispatcher.dispatch)
+```
+
+Dispatcher i wszyscy subskrybenci (CameraView, TelemetryCollector,
+InferenceManager) są podłączeni do dispatchera — źródło klatek jest dla nich
+transparentne.
+
+#### Inference toggle
+
+```python
+def _on_inference_toggled(self, enabled: bool):
+    if enabled:
+        inference.resume()
+        dispatcher.subscribe(inference.submit_frame, drop_if_busy=True)
+        bbox_overlay.visible = True
+        detection_label.setVisible(True)
+    else:
+        inference.pause()
+        dispatcher.unsubscribe(inference.submit_frame)
+        bbox_overlay.clear()
+        bbox_overlay.visible = False
+        detection_label.setVisible(False)
+        telemetry.clear_inference_stats()
+```
+
+`pause()` nie zatrzymuje procesu — tylko blokuje `submit_frame`. Proces
+pozostaje załadowany w pamięci.
+
+#### Status bar — counter detekcji
+
+```python
+self._detection_label = QLabel("")   # addPermanentWidget (prawa strona)
+```
+
+Pokazywany tylko gdy inference włączone. Aktualizowany przez
+`inference.detection_count_updated(int)` → `"Detections: 17 frames"`.
+
+---
+
+### 7. Telemetria + overlay — nowe pola inference
+
+#### `TelemetrySnapshot` — nowe pola
+
+```python
+@dataclass
+class TelemetrySnapshot:
+    # ... istniejące pola ...
+    inference_device: str | None = None    # "cpu" | "mps" | None
+    inference_time_ms: float | None = None  # rolling avg, None gdy wyłączone
+```
+
+#### `TelemetryCollector` — nowe metody
+
+```python
+def set_inference_stats(self, device: str, avg_ms: float) -> None: ...
+def clear_inference_stats(self) -> None: ...
+```
+
+Wywoływane z `MainWindow` przy każdym `inference_stats_updated` i przy
+wyłączeniu inference.
+
+#### `TelemetryOverlay` — nowe wiersze
+
+```
+FPS req   30.0
+FPS got   29.8
+Frame     33.5 ms
+Drop         0
+CPU sys    8.2 %
+CPU core  65.7 %
+Mem        71 MB
+Inf.dev    mps        ← widoczny tylko gdy model załadowany
+Inf.time   87 ms      ← rolling avg ostatnich 10 klatek
+```
+
+Wiersze `Inf.dev` i `Inf.time` znikają gdy inference jest wyłączone
+(`clear_inference_stats()` → pola `None` → `_format_lines` ich nie emituje).
+
+---
+
+### 8. Bugfixes (zidentyfikowane po uruchomieniu)
+
+#### `Unexpected frame size: 921600 bytes for 1280×720`
+
+**Przyczyna:** `frame.bits(0)` zwraca tylko płaszczyznę 0 (luma Y) dla formatów
+planarnych NV12/YUV420P — `1280 × 720 × 1 = 921600` zamiast `1280 × 720 × 3`.
+
+**Naprawa:** zamiana na `frame.toImage() → Format_RGB32 → bits()`. Qt dekoduje
+każdy format wewnętrznie. Identyczna ścieżka jak `CameraView.on_frame()`.
+
+#### `Subscriber not found for removal` (WARNING w logu)
+
+**Przyczyna:** `_on_inference_toggled(False)` wywoływał `dispatcher.unsubscribe()`
+zanim subscriber był dodany (pierwsze wyłączenie przed włączeniem).
+
+**Naprawa:** zmiana poziomu logu z `WARNING` na `DEBUG` w
+`FrameDispatcher.unsubscribe()` — brak subscribera nie jest błędem.
+
+---
+
+## Decyzje architektoniczne
+
+### Osobny proces zamiast wątku
+
+`multiprocessing.Process(context="spawn")` zamiast `QThread` lub `threading.Thread`:
+- Osobny GIL — inference nie blokuje Python event loop GUI
+- Crash workera (segfault, OOM) nie wywala aplikacji
+- `spawn` zamiast `fork` — wymagane na macOS od Python 3.12 (Apple deprecuje `fork`)
+
+### `toImage()` zamiast `bits(0)`
+
+`QVideoFrame.bits(plane)` daje surowe bajty jednej płaszczyzny. W formatach
+planarnych (NV12: Y w plane 0, UV w plane 1) to tylko część obrazu. `toImage()`
+wywołuje wewnętrzny dekoder Qt i zawsze zwraca kompletny obraz niezależnie od
+pixel formatu.
+
+### `WorkerReadyPacket` zamiast osobnego IPC kanału
+
+Worker wysyła `WorkerReadyPacket(device)` do tej samej `output_queue` zaraz
+po załadowaniu modelu. Manager odróżnia go przez `isinstance`. Eliminuje
+potrzebę dodatkowej kolejki lub pipe tylko dla metadanych startu.
+
+### Inference stats przez `TelemetryCollector`, nie bezpośrednio do overlay
+
+`InferenceManager.inference_stats_updated` → `MainWindow._on_inference_stats_updated`
+→ `TelemetryCollector.set_inference_stats()` → `TelemetrySnapshot.inference_*`
+→ `TelemetryOverlay.paint()`.
+
+Alternatywa: bezpośrednie połączenie `InferenceManager → TelemetryOverlay`.
+Wybrano pośrednie przez `TelemetryCollector` bo:
+- `TelemetrySnapshot` jest jedyną strukturą danych opisującą stan systemu
+- CSV logger automatycznie dostaje inference stats bez dodatkowego kodu
+- Overlay ma jeden spójny model danych

+## Instalacja
+
+```bash
+# Wymagane do inference:
+pip install ultralytics numpy
+# lub:
+pip install -e ".[inference]"
+```
+
+Aplikacja startuje bez tych pakietów — `Load Model…` zostaje aktywne, ale
+`InferenceManager.start()` zgłosi błąd jeśli `ultralytics` nie jest zainstalowany
+(obsłużony przez `try/except ImportError` w workerze → `output_queue.put(None)`
+→ manager emituje `inference_error`).
+
+---
+
+## Uruchamianie
+
+```bash
+# Windows dev
+.venv-win\Scripts\python.exe -m app.main
+
+# Mac Mini
+.venv/bin/python -m app.main
+
+# Mac Mini z plikiem wideo od razu (CLI nie zaimplementowany — użyj File → Open Video…)
+.venv/bin/python -m app.main
+```
+
+---
+
+## Next Steps
+
+1. Przetestować na Mac Mini z kamerą ELP:
+   - czy `_select_device()` wykrywa MPS i loguje `"MPS (Metal) available"`
+   - czy `Inf.dev mps` pojawia się w overlayzie
+   - czy `Inf.time` jest znacząco niższy niż na CPU
+
+2. OCR w tym samym procesie co YOLO:
+   - Worker process może obsługiwać wiele zadań — dodać `OcrTask` do `FramePacket`
+   - lub uruchomić OCR jako osobny subscriber `FrameDispatcher` w osobnym procesie
+
+3. Dodać możliwość regulacji progu confidence (`conf_threshold`) przez menu/dialog
+   — przekazać jako parametr do `run_worker()` w `FramePacket` lub przy starcie
+
+4. `set_active_format()` call po `_log_actual_format()` żeby menu zaznaczało
+   faktycznie działający format (nie żądany) — z poprzedniej sesji
+
+---
+
+## Critical Context
+
+- `WorkerReadyPacket` jest rozróżniany od `ResultPacket` przez `isinstance` —
+  nie używaj `None` jako sentinela dla obu typów
+- `_select_device()` wywołany raz przy starcie — jeśli zmienisz device w trakcie
+  działania, trzeba zrestartować workera
+- `BboxOverlay.on_detections(detections, source_size)` — `source_size` to
+  `tuple[int, int]` (width, height) klatki która była inferowana, nie aktualnego
+  widgetu; potrzebne do poprawnego skalowania przy zmianie rozdzielczości
+- `InferenceManager.pause()` nie zatrzymuje procesu — `submit_frame` tylko
+  sprawdza flagę; model pozostaje załadowany, można szybko wznowić
+- `multiprocessing.get_context("spawn")` — wymagane na macOS/Windows;
+  `fork` jest domyślny na Linux ale niebezpieczny z Qt
