## Configuration

### Native (TOML Config)

VuIO uses TOML configuration files on native platforms. Config location: `./config/config.toml`

```toml
[server]
port = 8080
interface = "0.0.0.0"
name = "VuIO Server"
uuid = "auto-generated"

[network]
interface_selection = "Auto"
multicast_ttl = 4
announce_interval_seconds = 30

[media]
scan_on_startup = true
watch_for_changes = true
cleanup_deleted_files = true
scan_playlists = true
supported_extensions = ["mp4", "mkv", "avi", "mp3", "flac", "wav", "jpg", "png"]

[[media.directories]]
path = "/home/user/Videos"
recursive = true
extensions = ["mp4", "mkv", "avi", "mov", "wmv", "webm"]
exclude_patterns = ["*.tmp", ".*"]
validation_mode = "Warn"  # Strict, Warn, or Skip

[[media.directories]]
path = "/home/user/Music"
recursive = true
extensions = ["mp3", "flac", "wav", "aac", "ogg", "wma", "m4a", "opus"]
exclude_patterns = ["*.tmp", ".*"]

[[media.directories]]
path = "/home/user/Pictures"
recursive = true
extensions = ["jpg", "jpeg", "png", "gif", "bmp", "webp"]
exclude_patterns = ["*.tmp", ".*"]

[database]
path = "~/.local/share/vuio/media.redb"
vacuum_on_startup = false
backup_enabled = true
```

### Configuration Options

**Server:**
- `port` - HTTP server port
- `interface` - Network interface to bind (0.0.0.0 for all)
- `name` - DLNA server friendly name
- `uuid` - Device UUID (auto-generated if not set)
- `ip` - Specific IP for DLNA announcements (optional)

**Network:**
- `interface_selection` - "Auto", "All", or specific interface name
- `multicast_ttl` - Multicast time-to-live
- `announce_interval_seconds` - SSDP announcement interval

**Media:**
- `scan_on_startup` - Scan directories on startup
- `watch_for_changes` - Real-time file monitoring
- `cleanup_deleted_files` - Auto-remove deleted files from database
- `scan_playlists` - Import M3U/PLS playlist files
- `supported_extensions` - Global list of media extensions

**Media Directories:**
- `path` - Directory path
- `recursive` - Scan subdirectories
- `extensions` - Override extensions for this directory
- `exclude_patterns` - Patterns to exclude (e.g., "*.tmp", ".*")
- `validation_mode` - Path validation: "Strict" (fail if missing), "Warn" (log warning), "Skip" (no validation)

**Database:**
- `path` - Database file location
- `vacuum_on_startup` - Compact database on startup
- `backup_enabled` - Enable automatic backups

## Audio Features

### Metadata Extraction

VuIO automatically extracts metadata from audio files:
- Title, Artist, Album, Album Artist
- Genre, Year, Track Number
- Duration
- Falls back to filename parsing when tags are missing

### Supported Audio Formats

- **Lossless:** FLAC, WAV, AIFF
- **Lossy:** MP3, AAC, OGG, WMA, OPUS, M4A

### Playlist Support

VuIO automatically discovers and imports playlist files:
- **M3U/M3U8** - Most common format
- **PLS** - WinAmp/iTunes compatible

Playlists are scanned from media directories on startup and made available to DLNA clients.

Configure: `scan_playlists = true` or `VUIO_SCAN_PLAYLISTS=true`

### Music Organization

Recommended directory structure:
```
/music/
├── Artist Name/
│   └── Album Name (Year)/
│       ├── 01 - Track.flac
│       └── folder.jpg
└── playlists/
    ├── favorites.m3u
    └── workout.pls
```

## Database

VuIO uses Redb, an embedded ACID-compliant database.

### Database Location

| Platform | Default Path |
|----------|--------------|
| **Windows** | `[exe dir]\config\database\media.redb` |
| **Linux** | `~/.local/share/vuio/media.redb` |
| **macOS** | `~/Library/Application Support/vuio/media.redb` |
| **Docker** | `/data/vuio.redb` (or `VUIO_DB_PATH`) |

When running from source on Windows:
```
C:\Users\Welcome\Downloads\code\rust\vuio\target\release\config\database\media.redb
```

### Reset Database

```bash
# Windows (PowerShell)
Remove-Item -Force .\target\release\config\database\media.redb

# Linux
rm -f ~/.local/share/vuio/media.redb

# macOS
rm -f ~/Library/Application\ Support/vuio/media.redb

# Docker
docker exec vuio-server rm -f /data/vuio.redb
```

VuIO will create a new database and rescan media on next startup.

## Platform Notes

### Windows

- Auto-excludes `Thumbs.db`, `desktop.ini`

### macOS
- Supports network volumes under `/Volumes`
- Auto-excludes `.DS_Store`, `.AppleDouble`
