URLs using the placeholder host `server` are rewritten to the configured file server (see File/API Server configuration). + - `autoplay` (boolean): start playback automatically when the event becomes active (default: true). + - `loop` (boolean): loop playback indefinitely. + - `volume` (float): 0.0–1.0 (mapped internally to VLC's 0–100 volume scale). +- If `python-vlc` is not installed, the Display Manager will fall back to launching the external `vlc` binary. +- The manager attempts to make the player window fullscreen and remove window decorations. For a truly panel-free fullscreen (no taskbar), run the Display Manager inside a minimal kiosk X session or a dedicated user session without a desktop panel (see the kiosk notes below). + +## 🌐 Web Events + +```json +{ + "web": { + "url": "https://dashboard.example.com" + } +} +``` + +Opens webpage in Chromium kiosk mode (fullscreen, no UI). + +## 🗂️ Project Structure + +``` +infoscreen-dev/ +├── .env # Environment configuration +├── README.md # This file +├── IMPRESSIVE_INTEGRATION.md # Detailed presentation system docs +├── src/ +│ ├── simclient.py # MQTT client (events, heartbeat, discovery) +│ ├── display_manager.py # Display controller (manages applications) +│ ├── requirements.txt # Python dependencies +│ ├── current_event.json # Current active event (runtime) +│ ├── config/ # Persistent client data +│ │ ├── client_uuid.txt +│ │ └── last_group_id.txt +│ ├── presentation/ # Downloaded presentation files +│ └── screenshots/ # Dashboard screenshots +├── scripts/ +│ ├── start-dev.sh # Start development client +│ ├── start-display-manager.sh # Start Display Manager +│ ├── test-display-manager.sh # Interactive testing +│ ├── test-impressive.sh # Test Impressive (auto-quit mode) +│ ├── test-impressive-loop.sh # Test Impressive (loop mode) +│ ├── test-mqtt.sh # Test MQTT connectivity +│ ├── test-screenshot.sh # Test screenshot capture +│ ├── test-utc-timestamps.sh # Test event timing +│ └── present-pdf-auto-advance.sh # PDF presentation wrapper +└── logs/ # Application logs +``` + +## 🧪 Testing + +### Test Display Manager + +```bash +./scripts/test-display-manager.sh +``` + +Interactive menu for testing: +- Check Display Manager status +- Create test events (presentation, video, webpage) +- View active processes +- Cycle through different event types + +### Test Impressive Presentation + +**Single playthrough (auto-quit):** +```bash +./scripts/test-impressive.sh +``` + +**Loop mode (infinite):** +```bash +./scripts/test-impressive-loop.sh +``` + +### Test MQTT Communication + +```bash +./scripts/test-mqtt.sh +``` + +Verifies MQTT broker connectivity and topics. + +### Test Screenshot Capture + +```bash +./scripts/test-screenshot.sh +``` + +Captures test screenshot for dashboard monitoring. + +## 🔧 Configuration Details + +### Environment Variables + +#### Environment +- `ENV` - `development` or `production` +- `DEBUG_MODE` - Enable debug output (1=on, 0=off) +- `LOG_LEVEL` - `DEBUG`, `INFO`, `WARNING`, `ERROR` + +#### MQTT +- `MQTT_BROKER` - Primary MQTT broker IP/hostname +- `MQTT_PORT` - MQTT port (default: 1883) +- `MQTT_BROKER_FALLBACKS` - Comma-separated fallback brokers +- `MQTT_USERNAME` - Optional authentication +- `MQTT_PASSWORD` - Optional authentication + +#### Timing +- `HEARTBEAT_INTERVAL` - Status update frequency (seconds) +- `SCREENSHOT_INTERVAL` - Dashboard screenshot frequency (seconds) +- `DISPLAY_CHECK_INTERVAL` - Event check frequency (seconds) + +#### File/API Server +- `FILE_SERVER_HOST` - Host/IP of the file server;

The display manager now prefers `event_type` when selecting which renderer to start. +- Web display: Chromium is launched in kiosk mode for web events. `website` events (scheduler) and legacy `web` keys are both supported and normalized. +- Auto-scroll feature: automatic scrolling for long websites implemented. Two mechanisms are available: + - CDP injection: The display manager attempts to inject a small auto-scroll script via Chrome DevTools Protocol (DevTools websocket) when possible (uses `websocket-client` and `requests`). Default injection duration: 60s. + - Extension fallback: When DevTools websocket handshakes are blocked (403), a tiny local Chrome extension (`src/chrome_autoscroll`) is loaded via `--load-extension` to run a content script that performs the auto-scroll reliably. +- Autoscroll enabled only for scheduler events with `event_type: "website"` (not for general `web` or `webpage`). The extension and CDP injection are only used when autoscroll is requested for that event type. +- New test utilities: + - `scripts/test_cdp.py` — quick DevTools JSON listing + Runtime.evaluate tester + - `scripts/test_cdp_origins.py` — tries several Origin headers to diagnose 403 handshakes +- Dependencies: `src/requirements.txt` updated to include `websocket-client` (used by the CDP injector). +- Small refactors and improved logging in `src/display_manager.py` to make event dispatch and browser injection more robust. + +If you rely on autoscroll in production, review the security considerations around `--remote-debugging-port` (DevTools) and prefer the extension fallback if your Chromium build enforces strict websocket Origin policies. diff --git a/SCHEDULER_FIELDS_SUPPORT.md b/SCHEDULER_FIELDS_SUPPORT.md new file mode 100644 index 0000000..02597dc --- /dev/null +++ b/SCHEDULER_FIELDS_SUPPORT.md @@ -0,0 +1,202 @@ +# Scheduler Fields Support + +## Overview + +The infoscreen client automatically preserves all fields sent by the scheduler in the event database, including scheduler-specific metadata fields like `page_progress` and `auto_progress`. + +## How It Works + +### Event Storage (`simclient.py`) + +When an event is received via MQTT on the `infoscreen/events/{group_id}` topic: + +1. **Full Preservation**: The `save_event_to_json()` function stores the complete event data using `json.dump()` without filtering +2. **No Data Loss**: All fields from the scheduler are preserved, including: + - `page_progress` - Current page/slide progress tracking + - `auto_progress` - Auto-progression state + - `occurrence_of_id` - Original event ID for recurring events + - `recurrence_rule` - iCal recurrence rule (RRULE format) + - `recurrence_end` - End date for recurring events + - Any other scheduler-specific fields + +3. **Debug Logging**: When `LOG_LEVEL=DEBUG`, the system logs the presence of `page_progress` and `auto_progress` fields + +### Event Processing (`display_manager.py`) + +The Display Manager: +- Uses scheduler-specific fields to control presentation behavior: + - `page_progress`: Controls Impressive's `--page-progress` option (overall progress bar) + - `auto_progress`: Controls Impressive's `--auto-progress` option (per-page countdown) +- Other scheduler-specific fields are preserved but not actively used by display logic + +## Example Event with Scheduler Fields + +```json +{ + "id": 57, + "occurrence_of_id": 57, + "group_id": 2, + "title": "2.
