## Discord Bot Setup

1. [Discord Developer Portal](https://discord.com/developers/applications) oeffnen
2. **Drei** Applications erstellen (z.B. "Jukebox Bot", "Radio Bot", "Notifications Bot")
3. Fuer jede Application:
   - Bot erstellen unter "Bot"
   - Token kopieren
   - **Privileged Gateway Intents** aktivieren:
     - Server Members Intent
     - Message Content Intent (optional)
   - Unter "OAuth2 > URL Generator":
     - Scopes: `bot`
     - Bot Permissions: `Connect`, `Speak`, `Use Voice Activity`, `Send Messages`, `Embed Links`
   - Generierte URL im Browser oeffnen, Bot zum Server einladen
4. Tokens als `DISCORD_TOKEN_JUKEBOX`, `DISCORD_TOKEN_RADIO` und `DISCORD_TOKEN_NOTIFICATIONS` setzen

## Persistenz

Alle Daten werden im `DATA_DIR` (`/data`) gespeichert:

```
/data/
├── sounds/
│   ├── hub-state.json  # Plugin-State (Volumes, Favorites, Channels, Profiles, ...)
│   ├── sound1.mp3
│   ├── subfolder/
│   │   └── sound2.wav
│   └── ...
```

State wird automatisch bei Aenderungen geschrieben (Atomic Writes mit `.tmp` + `.bak` Rotation) und beim Start geladen.

## Dockerfile (Multi-Stage)

4 Build-Stages:

1. **web-build** - React/Vite Frontend kompilieren
2. **server-deps** - npm install + native Build-Tools (python3, make, g++)
3. **server-build** - TypeScript Backend kompilieren + Dev-Dependencies entfernen
4. **runtime** - Finales Image (node:24-slim) mit FFmpeg + kompiliertem Code

Finales Image enthaelt nur Production Dependencies, kein TypeScript/Dev-Tooling.

## Streaming Qualitaets-Presets

Der Streamer kann vor dem Broadcast ein Preset waehlen:

| Preset | Aufloesung | FPS | Bitrate |
|--------|-----------|-----|---------|
| 720p30 | 1280x720 | 30 | 2.5 Mbit/s |
| 1080p30 | 1920x1080 | 30 | 5 Mbit/s |
| 1080p60 | 1920x1080 | 60 | 8 Mbit/s |
| 1440p60 | 2560x1440 | 60 | 14 Mbit/s |
| 4K60 | 3840x2160 | 60 | 25 Mbit/s |
| 4K165 Ultra | 3840x2160 | 165 | 50 Mbit/s |

Standard: 1080p60. Das Dropdown ist waehrend eines aktiven Broadcasts deaktiviert.
