+# Summary: File-Based Startup Configuration
+
+## ✅ Implementation Complete!
+
+Yes, startup options can now be configured via file in addition to command-line arguments and environment variables!
+
+## 🎯 Configuration Methods
+
+Jellyfin now supports **three ways** to configure startup paths:
+
+### 1. 📄 Configuration File (NEW!)
+- File: `startup.json`
+- Format: JSON
+- Location: Current directory, app directory, or config subdirectory
+- **Best for**: Production servers, containers, persistent configurations
+
+### 2. 🔧 Command-Line Arguments
+- Example: `--datadir /var/lib/jellyfin`
+- **Best for**: Testing, one-time overrides, debugging
+
+### 3. 🌍 Environment Variables
+- Example: `JELLYFIN_DATA_DIR=/var/lib/jellyfin`
+- **Best for**: System-wide settings, CI/CD, user-specific overrides
+
+## 📊 Priority Order
+
+When a path is configured in multiple places, Jellyfin uses this priority (highest to lowest):
+
+```
+1. Command-line options (--datadir, etc.)
+ ↓
+2. Environment variables (JELLYFIN_DATA_DIR, etc.)
+ ↓
+3. Configuration file (startup.json)
+ ↓
+4. Default values
+```
+
+## 📁 Configuration File Format
+
+Create a file named `startup.json`:
+
+```json
+{
+ "Paths": {
+ "DataDir": "/var/lib/jellyfin",
+ "ConfigDir": "/etc/jellyfin",
+ "CacheDir": "/var/cache/jellyfin",
+ "LogDir": "/var/log/jellyfin",
+ "TempDir": "/var/tmp/jellyfin",
+ "WebDir": "/usr/share/jellyfin/web"
+ }
+}
+```
+
+### All Properties are Optional!
+
+You can omit any property or set it to `null`, and Jellyfin will fall back to environment variables or defaults:
+
+```json
+{
+ "Paths": {
+ "DataDir": "/custom/data"
+ }
+}
+```
+
+## 📍 File Locations
+
+The `startup.json` file is searched in these locations (first found is used):
+
+1. `./startup.json` (current working directory)
+2. `{AppDirectory}/startup.json`
+3. `{AppDirectory}/config/startup.json`
+
+## 🔧 Changes Made
+
+### New Files Created
+1. **Jellyfin.Server/Resources/Configuration/startup.default.json** - Default template
+2. **startup.json.example** - User-friendly example with documentation
+3. **FILE_BASED_STARTUP_CONFIG.md** - Comprehensive documentation
+
+### Code Changes
+1. **Jellyfin.Server/Helpers/StartupHelpers.cs**
+ - Added `LoadStartupConfiguration()` method
+ - Searches for `startup.json` in multiple locations
+ - Integrates file-based config into path resolution
+ - Priority: CLI > Env Var > Config File > Default
+
+### Modified Path Resolution
+All six paths now support configuration file:
+- DataDir
+- ConfigDir
+- CacheDir
+- LogDir
+- TempDir
+- WebDir
+
+## 💡 Use Cases
+
+### 1. Production Server
+```json
+{
+ "Paths": {
+ "DataDir": "/var/lib/jellyfin",
+ "ConfigDir": "/etc/jellyfin",
+ "CacheDir": "/var/cache/jellyfin",
+ "LogDir": "/var/log/jellyfin",
+ "TempDir": "/var/tmp/jellyfin"
+ }
+}
+```
+
+### 2. Docker Container
+```json
+{
+ "Paths": {
+ "DataDir": "/data",
+ "ConfigDir": "/config",
+ "CacheDir": "/cache",
+ "TempDir": "/temp"
+ }
+}
+```
+
+### 3. Portable Installation
+```json
+{
+ "Paths": {
+ "DataDir": "./data",
+ "ConfigDir": "./config",
+ "CacheDir": "./cache",
+ "LogDir": "./logs",
+ "TempDir": "./temp"
+ }
+}
+```
+
+### 4. Performance Optimization
+```json
+{
+ "Paths": {
+ "DataDir": "/mnt/hdd/jellyfin/data",
+ "CacheDir": "/mnt/ssd/jellyfin/cache",
+ "TempDir": "/mnt/nvme/jellyfin/temp"
+ }
+}
+```
+
+## ✅ Validation
+
+When Jellyfin starts, it logs the configuration file being used:
+
+```
+Loaded startup configuration from: /path/to/startup.json
+```
+
+If the file has errors:
+
+```
+Warning: Failed to load startup configuration from /path/to/startup.json: [error]
+```
+
+All resolved paths are logged:
+
+```
+[INF] Program data path: /var/lib/jellyfin
+[INF] Config directory path: /etc/jellyfin
+[INF] Cache path: /var/cache/jellyfin
+[INF] Log directory path: /var/log/jellyfin
+[INF] Temp directory path: /var/tmp/jellyfin
+[INF] Web resources path: /usr/share/jellyfin/web
+```
+
+## 🎨 Example Scenarios
+
+### Scenario 1: Basic File Configuration
+**startup.json:**
+```json
+{
+ "Paths": {
+ "DataDir": "/var/lib/jellyfin"
+ }
+}
+```
+**Result:** DataDir from file, all others use defaults
+
+### Scenario 2: Mixed Configuration
+**startup.json:**
+```json
+{
+ "Paths": {
+ "DataDir": "/var/lib/jellyfin",
+ "ConfigDir": "/etc/jellyfin"
+ }
+}
+```
+**Environment:**
+```bash
+export JELLYFIN_TEMP_DIR=/fast-storage/temp
+```
+**Result:**
+- DataDir & ConfigDir from file
+- TempDir from environment variable
+- Others use defaults
+
+### Scenario 3: Override Everything
+**startup.json:**
+```json
+{
+ "Paths": {
+ "DataDir": "/var/lib/jellyfin"
+ }
+}
+```
+**Command line:**
+```bash
+jellyfin --datadir /tmp/testing
+```
+**Result:** DataDir from command line (highest priority)
+
+## 📦 Migration Guide
+
+### From Environment Variables
+
+**Before:**
+```bash
+export JELLYFIN_DATA_DIR=/var/lib/jellyfin
+export JELLYFIN_CONFIG_DIR=/etc/jellyfin
+export JELLYFIN_CACHE_DIR=/var/cache/jellyfin
+```
+
+**After:**
+Create `startup.json`:
+```json
+{
+ "Paths": {
+ "DataDir": "/var/lib/jellyfin",
+ "ConfigDir": "/etc/jellyfin",
+ "CacheDir": "/var/cache/jellyfin"
+ }
+}
+```
+
+Then remove environment variables.
+
+### From Command-Line Arguments
+
+**Before:**
+```bash
+jellyfin --datadir /var/lib/jellyfin --configdir /etc/jellyfin --cachedir /var/cache/jellyfin
+```
+
+**After:**
+Create `startup.json` and run:
+```bash
+jellyfin
+```
+
+## 🐳 Docker Integration
+
+**docker-compose.yml:**
+```yaml
+version: '3.8'
+services:
+ jellyfin:
+ image: jellyfin/jellyfin
+ volumes:
+ - ./startup.json:/app/startup.json
+ - jellyfin_data:/data
+ - jellyfin_config:/config
+ - jellyfin_cache:/cache
+```
+
+**startup.json:**
+```json
+{
+ "Paths": {
+ "DataDir": "/data",
+ "ConfigDir": "/config",
+ "CacheDir": "/cache"
+ }
+}
+```
+
+## 🔒 Security
+
+- Keep `startup.json` readable only by Jellyfin user

+# File-Based Startup Configuration
+
+## Overview
+Jellyfin now supports file-based configuration for all startup paths in addition to command-line options and environment variables. This provides a persistent, portable way to configure your Jellyfin installation.
+
+## Configuration Priority
+
+When determining which path to use, Jellyfin follows this priority (highest to lowest):
+
+1. **Command-line options** (e.g., `--datadir`)
+2. **Environment variables** (e.g., `JELLYFIN_DATA_DIR`)
+3. **Configuration file** (`startup.json`)
+4. **Default values**
+
+This allows you to set defaults in a file, override them with environment variables for different environments, and temporarily override with command-line options for testing.
+
+## Configuration File Location
+
+The `startup.json` file is searched in the following locations (in order):
+
+1. **Current working directory**: `./startup.json`
+2. **Application directory**: `{AppDir}/startup.json`
+3. **Config subdirectory**: `{AppDir}/config/startup.json`
+
+The first file found will be used.
+
+## File Format
+
+Create a file named `startup.json` with the following structure:
+
+```json
+{
+ "Paths": {
+ "DataDir": "/var/lib/jellyfin",
+ "ConfigDir": "/etc/jellyfin",
+ "CacheDir": "/var/cache/jellyfin",
+ "LogDir": "/var/log/jellyfin",
+ "TempDir": "/var/tmp/jellyfin",
+ "WebDir": "/usr/share/jellyfin/web"
+ }
+}
+```
+
+### Supported Properties
+
+All path properties are **optional**. Any property can be set to `null` or omitted entirely, and the system will fall back to environment variables or defaults.
+
+| Property | Description | Equivalent CLI | Equivalent Env Var |
+|----------|-------------|----------------|-------------------|
+| `DataDir` | Database and data files | `--datadir` | `JELLYFIN_DATA_DIR` |
+| `ConfigDir` | Configuration files | `--configdir` | `JELLYFIN_CONFIG_DIR` |
+| `CacheDir` | Cache files | `--cachedir` | `JELLYFIN_CACHE_DIR` |
+| `LogDir` | Log files | `--logdir` | `JELLYFIN_LOG_DIR` |
+| `TempDir` | Temporary files | `--tempdir` | `JELLYFIN_TEMP_DIR` |
+| `WebDir` | Web client files | `--webdir` | `JELLYFIN_WEB_DIR` |
+
+## Example Configurations
+
+### Linux Production Server
+
+```json
+{
+ "Paths": {
+ "DataDir": "/var/lib/jellyfin",
+ "ConfigDir": "/etc/jellyfin",
+ "CacheDir": "/var/cache/jellyfin",
+ "LogDir": "/var/log/jellyfin",
+ "TempDir": "/var/tmp/jellyfin",
+ "WebDir": "/usr/share/jellyfin/web"
+ }
+}
+```
+
+### Windows Production Server
+
+```json
+{
+ "Paths": {
+ "DataDir": "C:\\ProgramData\\Jellyfin\\data",
+ "ConfigDir": "C:\\ProgramData\\Jellyfin\\config",
+ "CacheDir": "D:\\Cache\\Jellyfin",
+ "LogDir": "C:\\ProgramData\\Jellyfin\\logs",
+ "TempDir": "D:\\Temp\\Jellyfin",
+ "WebDir": "C:\\Program Files\\Jellyfin\\web"
+ }
+}
+```
+
+### Development Configuration
+
+```json
+{
+ "Paths": {
+ "DataDir": "./dev-data",
+ "ConfigDir": "./dev-config",
+ "CacheDir": "./dev-cache",
+ "LogDir": "./dev-logs",
+ "TempDir": "./dev-temp",
+ "WebDir": "./wwwroot"
+ }
+}
+```
+
+### Minimal Configuration (Using Defaults)
+
+```json
+{
+ "Paths": {
+ "DataDir": "/custom/jellyfin/data"
+ }
+}
+```
+
+In this example, only `DataDir` is overridden. All other paths will use their default values or environment variables.
+
+### Partial Override with Environment Variables
+
+**startup.json:**
+```json
+{
+ "Paths": {
+ "DataDir": "/var/lib/jellyfin",
+ "ConfigDir": "/etc/jellyfin"
+ }
+}
+```
+
+**Environment variables:**
+```bash
+export JELLYFIN_TEMP_DIR=/fast-storage/jellyfin-temp
+```
+
+**Result:** DataDir and ConfigDir come from the file, TempDir from environment variable, and all others use defaults.
+
+## Use Cases
+
+### 1. Containerized Deployments
+
+**Docker Example:**
+Create `startup.json` in your config volume:
+
+```json
+{
+ "Paths": {
+ "DataDir": "/data",
+ "ConfigDir": "/config",
+ "CacheDir": "/cache",
+ "LogDir": "/logs",
+ "TempDir": "/temp"
+ }
+}
+```
+
+**docker-compose.yml:**
+```yaml
+version: '3.8'
+services:
+ jellyfin:
+ image: jellyfin/jellyfin
+ volumes:
+ - ./startup.json:/config/startup.json
+ - jellyfin_data:/data
+ - jellyfin_cache:/cache
+ - jellyfin_logs:/logs
+ - jellyfin_temp:/temp
+```
+
+### 2. Multiple Instance Setup
+
+Run multiple Jellyfin instances with different configurations:
+
+**Instance 1 (startup-prod.json):**
+```json
+{
+ "Paths": {
+ "DataDir": "/srv/jellyfin/prod/data",
+ "ConfigDir": "/srv/jellyfin/prod/config",
+ "LogDir": "/srv/jellyfin/prod/logs"
+ }
+}
+```
+
+**Instance 2 (startup-test.json):**
+```json
+{
+ "Paths": {
+ "DataDir": "/srv/jellyfin/test/data",
+ "ConfigDir": "/srv/jellyfin/test/config",
+ "LogDir": "/srv/jellyfin/test/logs"
+ }
+}
+```
+
+### 3. Portable Installation
+
+Create a portable Jellyfin installation with relative paths:
+
+```json
+{
+ "Paths": {
+ "DataDir": "./data",
+ "ConfigDir": "./config",
+ "CacheDir": "./cache",
+ "LogDir": "./logs",
+ "TempDir": "./temp",
+ "WebDir": "./web"
+ }
+}
+```
+
+### 4. Performance Optimization
+
+Place different directories on different storage devices:
+
+```json
+{
+ "Paths": {
+ "DataDir": "/mnt/hdd/jellyfin/data",
+ "ConfigDir": "/mnt/ssd/jellyfin/config",
+ "CacheDir": "/mnt/ssd/jellyfin/cache",
+ "TempDir": "/mnt/nvme/jellyfin/temp",
+ "LogDir": "/mnt/hdd/jellyfin/logs"
+ }
+}
+```
+
+## Validation
+
+When Jellyfin starts, it will log the configuration file being used:
+
+```
+Loaded startup configuration from: /path/to/startup.json
+```
+
+If the file has syntax errors, you'll see:
+
+```
+Warning: Failed to load startup configuration from /path/to/startup.json: [error message]
+```
+
+All resolved paths are logged at startup:
+
+```
+[INF] Program data path: /var/lib/jellyfin
+[INF] Config directory path: /etc/jellyfin
+[INF] Cache path: /var/cache/jellyfin
+[INF] Log directory path: /var/log/jellyfin
+[INF] Temp directory path: /var/tmp/jellyfin
+[INF] Web resources path: /usr/share/jellyfin/web
+```
+
+## Troubleshooting
+
+### Configuration File Not Found
+
+If your configuration file isn't being loaded:
+
+1. Check the file is named exactly `startup.json`
+2. Verify it's in one of the search locations
+3. Check file permissions (must be readable)
+4. Look for typos in the JSON structure
+
+### Invalid JSON Syntax
+
+Common JSON errors:
+
+```json
+// ❌ Wrong - trailing comma
+{
+ "Paths": {
+ "DataDir": "/var/lib/jellyfin",
+ }
+}
+
+// ✅ Correct
+{
+ "Paths": {
+ "DataDir": "/var/lib/jellyfin"
+ }
+}
+
+// ❌ Wrong - single quotes
+{
+ "Paths": {
+ 'DataDir': '/var/lib/jellyfin'
+ }
+}
+
+// ✅ Correct - double quotes
+{
+ "Paths": {
+ "DataDir": "/var/lib/jellyfin"
+ }
+}
+```
+
+### Path Resolution Order
+
+Remember the priority:
+1. CLI argument beats everything
+2. Environment variable beats config file
+3. Config file beats defaults
+
+To test which source is being used, try setting different values in each and check the startup logs.
+
+## Migration from Environment Variables
+
+If you currently use environment variables, you can migrate to a config file:
+
+**Before (environment variables):**
+```bash
+export JELLYFIN_DATA_DIR=/var/lib/jellyfin
+export JELLYFIN_CONFIG_DIR=/etc/jellyfin
+export JELLYFIN_CACHE_DIR=/var/cache/jellyfin
+export JELLYFIN_LOG_DIR=/var/log/jellyfin
+```
+
+**After (startup.json):**
+```json
+{
+ "Paths": {
+ "DataDir": "/var/lib/jellyfin",
+ "ConfigDir": "/etc/jellyfin",
+ "CacheDir": "/var/cache/jellyfin",
+ "LogDir": "/var/log/jellyfin"
+ }
+}
+```
+
+Then remove the environment variables from your `.bashrc`, systemd service, or wherever they're defined.
+
+## Benefits
+
+### Advantages of File-Based Configuration
+
+1. **Portability**: Easy to copy configuration between systems
+2. **Version Control**: Track configuration changes in Git
+3. **Documentation**: Self-documenting with comments (in extended formats)
+4. **Persistence**: Survives system reboots and shell sessions
+5. **Consistency**: Same configuration across all instances
+6. **No Shell Escaping**: No need to worry about shell quoting rules
+7. **Easy Editing**: Simple text file, easy to modify
+8. **Backup**: Can be backed up with other configuration files
+
+### When to Use Each Method
+
+| Method | Best For |
+|--------|----------|
+| **Config File** | Production servers, containers, permanent installations |
+| **Environment Variables** | System-wide settings, CI/CD pipelines, user-specific overrides |
+| **Command Line** | Testing, one-time overrides, debugging |
+
+## Security Considerations
+
+- Keep `startup.json` readable only by the Jellyfin user
+- Don't commit sensitive paths to public repositories
+- Use environment variables for secrets (like database passwords)
+- Consider using separate config files per environment (dev/staging/prod)

+# Jellyfin Path Configuration Guide
+
+## Overview
+All major paths in Jellyfin are now fully configurable through **three methods**: configuration file, command-line options, or environment variables. This allows you to customize where Jellyfin stores its data, logs, cache, configuration, and temporary files.
+
+## Configuration Methods
+
+Jellyfin supports three ways to configure paths (in priority order):
+
+### 1. Configuration File (NEW!)
+Create a `startup.json` file with your path configurations. See [FILE_BASED_STARTUP_CONFIG.md](FILE_BASED_STARTUP_CONFIG.md) for details.
+
+**Example:**
+```json
+{
+ "Paths": {
+ "DataDir": "/var/lib/jellyfin",
+ "ConfigDir": "/etc/jellyfin",
+ "CacheDir": "/var/cache/jellyfin",
+ "LogDir": "/var/log/jellyfin",
+ "TempDir": "/var/tmp/jellyfin"
+ }
+}
+```
+
+### 2. Command-Line Options
+Pass options when starting Jellyfin.
+
+**Example:**
+```bash
+jellyfin --datadir /var/lib/jellyfin --logdir /var/log/jellyfin
+```
+
+### 3. Environment Variables
+Set environment variables in your shell or systemd service.
+
+**Example:**
+```bash
+export JELLYFIN_DATA_DIR=/var/lib/jellyfin
+export JELLYFIN_LOG_DIR=/var/log/jellyfin
+```
+
+## Priority Order
+
+When a path is configured in multiple places, Jellyfin uses this priority (highest to lowest):
+
+1. **Command-line options** (highest priority)
+2. **Environment variables**
+3. **Configuration file** (`startup.json`)
+4. **Default values** (lowest priority)
+
+This allows you to:
+- Set defaults in a configuration file
+- Override system-wide with environment variables
+- Override temporarily with command-line options
+
+## Available Path Configurations
+
+### 1. Program Data Directory (Database Files)
+**Purpose**: Main directory for database files and application data
+
+- **Configuration File**: `Paths:DataDir` in `startup.json`
+- **Command Line**: `-d, --datadir `
+- **Environment Variable**: `JELLYFIN_DATA_DIR`
+- **Default**:
+ - Windows: `%LocalAppData%\jellyfin`
+ - Linux/Unix: `$XDG_DATA_HOME/jellyfin` or `~/.local/share/jellyfin`
+ - macOS: `~/Library/Application Support/jellyfin`
+
+**Example**:
+```bash
+# Configuration file (startup.json)
+{
+ "Paths": {
+ "DataDir": "/var/lib/jellyfin"
+ }
+}
+
+# Command line
+jellyfin --datadir /var/lib/jellyfin
+
+# Environment variable
+export JELLYFIN_DATA_DIR=/var/lib/jellyfin
+```
+
+### 2. Configuration Directory
+**Purpose**: User settings, pictures, and configuration files
+
+- **Configuration File**: `Paths:ConfigDir` in `startup.json`
+- **Command Line**: `-c, --configdir `
+- **Environment Variable**: `JELLYFIN_CONFIG_DIR`
+- **Default**:
+ - Windows/macOS: `{datadir}/config`
+ - Linux/Unix: `$XDG_CONFIG_HOME/jellyfin` or `~/.config/jellyfin`
+
+**Example**:
+```bash
+# Configuration file
+{
+ "Paths": {
+ "ConfigDir": "/etc/jellyfin"
+ }
+}
+
+# Command line
+jellyfin --configdir /etc/jellyfin
+
+# Environment variable
+export JELLYFIN_CONFIG_DIR=/etc/jellyfin
+```
+
+### 3. Cache Directory
+**Purpose**: Image cache, metadata cache, and other temporary cached data
+
+- **Configuration File**: `Paths:CacheDir` in `startup.json`
+- **Command Line**: `-C, --cachedir `
+- **Environment Variable**: `JELLYFIN_CACHE_DIR`
+- **Default**:
+ - Windows/macOS: `{datadir}/cache`
+ - Linux/Unix: `$XDG_CACHE_HOME/jellyfin` or `~/.cache/jellyfin`
+
+**Example**:
+```bash
+# Configuration file
+{
+ "Paths": {
+ "CacheDir": "/var/cache/jellyfin"
+ }
+}
+
+# Command line
+jellyfin --cachedir /var/cache/jellyfin
+
+# Environment variable
+export JELLYFIN_CACHE_DIR=/var/cache/jellyfin
+```
+
+### 4. Log Directory
+**Purpose**: Application log files
+
+- **Configuration File**: `Paths:LogDir` in `startup.json`
+- **Command Line**: `-l, --logdir `
+- **Environment Variable**: `JELLYFIN_LOG_DIR`
+- **Default**: `{datadir}/log`
+
+**Example**:
+```bash
+# Configuration file
+{
+ "Paths": {
+ "LogDir": "/var/log/jellyfin"
+ }
+}
+
+# Command line
+jellyfin --logdir /var/log/jellyfin
+
+# Environment variable
+export JELLYFIN_LOG_DIR=/var/log/jellyfin
+```
+
+### 5. Temp Directory ⭐ NEW
+**Purpose**: Temporary files created during transcoding and other operations
+
+- **Configuration File**: `Paths:TempDir` in `startup.json`
+- **Command Line**: `-t, --tempdir `
+- **Environment Variable**: `JELLYFIN_TEMP_DIR`
+- **Default**: `{system_temp}/jellyfin` (e.g., `/tmp/jellyfin` on Linux)
+
+**Example**:
+```bash
+# Configuration file
+{
+ "Paths": {
+ "TempDir": "/var/tmp/jellyfin"
+ }
+}
+
+# Command line
+jellyfin --tempdir /var/tmp/jellyfin
+
+# Environment variable
+export JELLYFIN_TEMP_DIR=/var/tmp/jellyfin
+```
+
+### 6. Web Client Directory
+**Purpose**: Location of the Jellyfin web client files
+
+- **Configuration File**: `Paths:WebDir` in `startup.json`
+- **Command Line**: `-w, --webdir `
+- **Environment Variable**: `JELLYFIN_WEB_DIR`
+- **Default**:
+ 1. Searches for `wwwroot` folder in solution root (development)
+ 2. Falls back to `{appdir}/jellyfin-web`
+
+**Example**:
+```bash
+# Configuration file
+{
+ "Paths": {
+ "WebDir": "/usr/share/jellyfin/web"
+ }
+}
+
+# Command line
+jellyfin --webdir /usr/share/jellyfin/web
+
+# Environment variable
+export JELLYFIN_WEB_DIR=/usr/share/jellyfin/web
+```
+
+## Usage Examples
+
+### Using Command Line Options
+```bash
+# Windows
+jellyfin.exe --datadir "C:\ProgramData\Jellyfin" --logdir "C:\Logs\Jellyfin" --tempdir "D:\Temp\Jellyfin"
+
+# Linux
+jellyfin --datadir /var/lib/jellyfin --logdir /var/log/jellyfin --tempdir /var/tmp/jellyfin --cachedir /var/cache/jellyfin
+```
+
+### Using Environment Variables
+```bash
+# Linux/macOS - Add to ~/.bashrc or /etc/environment
+export JELLYFIN_DATA_DIR=/var/lib/jellyfin
+export JELLYFIN_CONFIG_DIR=/etc/jellyfin
+export JELLYFIN_CACHE_DIR=/var/cache/jellyfin
+export JELLYFIN_LOG_DIR=/var/log/jellyfin
+export JELLYFIN_TEMP_DIR=/var/tmp/jellyfin
+export JELLYFIN_WEB_DIR=/usr/share/jellyfin/web
+
+# Windows - Set in PowerShell or System Properties
+$env:JELLYFIN_DATA_DIR="C:\ProgramData\Jellyfin"
+$env:JELLYFIN_LOG_DIR="C:\Logs\Jellyfin"
+$env:JELLYFIN_TEMP_DIR="D:\Temp\Jellyfin"
+```
+
+### Systemd Service (Linux)
+Create or edit `/etc/systemd/system/jellyfin.service`:
+
+```ini
+[Unit]
+Description=Jellyfin Media Server
+After=network-online.target
+
+[Service]
+Type=simple
+User=jellyfin
+Group=jellyfin
+Environment="JELLYFIN_DATA_DIR=/var/lib/jellyfin"
+Environment="JELLYFIN_CONFIG_DIR=/etc/jellyfin"
+Environment="JELLYFIN_CACHE_DIR=/var/cache/jellyfin"
+Environment="JELLYFIN_LOG_DIR=/var/log/jellyfin"
+Environment="JELLYFIN_TEMP_DIR=/var/tmp/jellyfin"
+Environment="JELLYFIN_WEB_DIR=/usr/share/jellyfin/web"
+ExecStart=/usr/bin/jellyfin
+
+[Install]
+WantedBy=multi-user.target
+```
+
+## Priority Order
+
+When determining which path to use, Jellyfin follows this priority:
+
+1. **Command-line option** (highest priority)
+2. **Environment variable**
+3. **Default value** (lowest priority)
+
+This allows you to:
+- Set system-wide defaults via environment variables
+- Override on a per-run basis with command-line options
+- Fall back to sensible defaults if nothing is specified
+
+## Directory Permissions
+
+Ensure the user running Jellyfin has appropriate permissions:
+
+```bash
+# Linux example - create directories and set permissions
+sudo mkdir -p /var/lib/jellyfin /etc/jellyfin /var/cache/jellyfin /var/log/jellyfin /var/tmp/jellyfin
+sudo chown -R jellyfin:jellyfin /var/lib/jellyfin /etc/jellyfin /var/cache/jellyfin /var/log/jellyfin /var/tmp/jellyfin
+sudo chmod 755 /var/lib/jellyfin /etc/jellyfin /var/cache/jellyfin /var/log/jellyfin /var/tmp/jellyfin
+```
+
+## Benefits
+
+### Performance
+- Place temp directory on fast storage (SSD/NVMe) for transcoding performance
+- Put cache on separate disk to reduce I/O contention
+- Use different mount points for logs vs data
+
+### Storage Management
+- Separate data across different partitions/disks
+- Use network storage for backups while keeping temp on local fast storage
+- Easier to manage disk space quotas
+
+### Security
+- Follow OS security best practices (e.g., `/var` hierarchy on Linux)
+- Set appropriate permissions per directory type
+- Separate user data from system configuration
+
+### Containerization
+- Map volumes to specific paths
+- Follow container best practices (ephemeral temp, persistent data)
+- Easier Docker/Podman volume mounting
+
+### Backup & Maintenance
+- Backup only important directories (data, config) and skip cache/temp
+- Easier to exclude temporary files from backups
+- Simplified cleanup of cache and temp directories
+
+## Docker Example
+
+```yaml
+version: '3.8'
+services:
+ jellyfin:
+ image: jellyfin/jellyfin:latest
+ environment:
+ - JELLYFIN_DATA_DIR=/data
+ - JELLYFIN_CONFIG_DIR=/config
+ - JELLYFIN_CACHE_DIR=/cache
+ - JELLYFIN_LOG_DIR=/log
+ - JELLYFIN_TEMP_DIR=/temp
+ volumes:
+ - /host/jellyfin/data:/data
+ - /host/jellyfin/config:/config
+ - /host/jellyfin/cache:/cache
+ - /host/jellyfin/log:/log
+ - /fast-storage/jellyfin/temp:/temp
+ ports:
+ - "8096:8096"
+```
+
+## Verification
+
+After starting Jellyfin, check the logs to verify paths are set correctly:
+
+```
+[INF] Program data path: /var/lib/jellyfin
+[INF] Config directory path: /etc/jellyfin
+[INF] Cache path: /var/cache/jellyfin
+[INF] Log directory path: /var/log/jellyfin
+[INF] Temp directory path: /var/tmp/jellyfin
+[INF] Web resources path: /usr/share/jellyfin/web
+```
+
+## Notes
+
+- All paths are created automatically if they don't exist (permissions allowing)
+- Paths are normalized to absolute paths internally
+- Relative paths are resolved from the current working directory
+- Changes require a restart to take effect
+- Command-line help: `jellyfin --help`

+# Summary: Path Configuration Enhancement
+
+## Changes Made
+
+### ✅ All Paths Are Now Configurable!
+
+All major Jellyfin paths can be configured via command-line options or environment variables:
+
+| Path Type | Command Line | Environment Variable | Default |
+|-----------|-------------|---------------------|---------|
+| **Program Data** | `-d, --datadir` | `JELLYFIN_DATA_DIR` | `%LocalAppData%/jellyfin` |
+| **Configuration** | `-c, --configdir` | `JELLYFIN_CONFIG_DIR` | `{datadir}/config` or XDG |
+| **Cache** | `-C, --cachedir` | `JELLYFIN_CACHE_DIR` | `{datadir}/cache` or XDG |
+| **Logs** | `-l, --logdir` | `JELLYFIN_LOG_DIR` | `{datadir}/log` |
+| **Temp** ⭐ | `-t, --tempdir` | `JELLYFIN_TEMP_DIR` | `{system_temp}/jellyfin` |
+| **Web Client** | `-w, --webdir` | `JELLYFIN_WEB_DIR` | `wwwroot` or `jellyfin-web` |
+
+### New Feature: Configurable Temp Directory
+
+**Previously**: Temp directory was hardcoded to `{system_temp}/jellyfin`
+
+**Now**: Fully configurable with:
+- Command-line option: `-t, --tempdir `
+- Environment variable: `JELLYFIN_TEMP_DIR`
+- Maintains backward compatibility with sensible default
+
+## Files Modified
+
+1. **Jellyfin.Server/StartupOptions.cs**
+ - Added `TempDir` property with command-line option `-t, --tempdir`
+
+2. **Emby.Server.Implementations/AppBase/BaseApplicationPaths.cs**
+ - Changed `TempDirectory` from computed property to stored property
+ - Added `tempDirectoryPath` parameter to constructor
+
+3. **Emby.Server.Implementations/ServerApplicationPaths.cs**
+ - Added `tempDirectoryPath` parameter to constructor
+ - Passes temp directory to base class
+
+4. **Jellyfin.Server/Helpers/StartupHelpers.cs**
+ - Added logic to resolve temp directory from options/env var/default
+ - Creates temp directory during initialization
+ - Passes temp directory to ServerApplicationPaths constructor
+
+## Usage Examples
+
+### Command Line
+```bash
+# Linux
+jellyfin --tempdir /var/tmp/jellyfin
+
+# Windows
+jellyfin.exe --tempdir "D:\Temp\Jellyfin"
+
+# All paths at once
+jellyfin --datadir /var/lib/jellyfin --configdir /etc/jellyfin --cachedir /var/cache/jellyfin --logdir /var/log/jellyfin --tempdir /var/tmp/jellyfin
+```
+

+# Troubleshooting: EF Core Pending Model Changes Warning
+
+## Issue Description
+
+When deploying Jellyfin to a test/production environment, you may encounter this error:
+
+```
+System.InvalidOperationException: The model for context 'JellyfinDbContext' has pending changes.
+Add a new migration before updating the database.
+```
+
+This error occurs when Entity Framework Core detects that the database model has changed but there isn't a corresponding migration file.
+
+## Root Causes
+
+### 1. Missing Migration Files (Most Common)
+The development machine has all the migration files, but they weren't deployed to the test/production machine.
+
+**Solution**: Ensure all migration files are deployed with your application.
+
+#### Check for Migration Files
+
+**Location:** `src/Jellyfin.Database/Jellyfin.Database.Providers.Postgres/Migrations/`
+
+Files should include:
+- `*.cs` - Migration classes
+- `*.Designer.cs` - Migration metadata
+- `JellyfinDbContextModelSnapshot.cs` - Current model snapshot
+
+**Verify on test machine:**
+```bash
+# Check if migration files exist
+ls /opt/pgsql-jellyfin/src/Jellyfin.Database/Jellyfin.Database.Providers.Postgres/Migrations/
+
+# Count migration files
+find /opt/pgsql-jellyfin -name "*Migration*.cs" | wc -l
+```
+
+### 2. Build Configuration Mismatch
+Migration files might be excluded from the build output.
+
+**Solution:** Check your `.csproj` file:
+
+```xml
+
+
+
+
+```
+
+### 3. Model Changed Without Migration
+The code has model changes that haven't been captured in a migration.
+
+**Solution:** Generate a new migration on your development machine:
+
+```bash
+# Navigate to the project directory
+cd src/Jellyfin.Database/Jellyfin.Database.Providers.Postgres/
+
+# Create a new migration
+dotnet ef migrations add YourMigrationName --context JellyfinDbContext
+
+# Rebuild and redeploy
+dotnet build
+```
+
+### 4. Different .NET SDK Versions
+Different SDK versions might have different EF Core behaviors.
+
+**Solution:** Ensure both machines use the same .NET SDK version:
+
+```bash
+# Check version
+dotnet --version
+
+# Should be .NET 11 or later
+```
+
+## Fix Applied in Code
+
+We've suppressed the `PendingModelChangesWarning` in the database provider configuration since we explicitly handle migrations in our startup code:
+
+### PostgreSQL Provider
+```csharp
+options
+ .UseNpgsql(connectionString, options => /* ... */)
+ .ConfigureWarnings(warnings =>
+ warnings.Ignore(RelationalEventId.PendingModelChangesWarning));
+```
+
+### SQLite Provider
+```csharp
+options
+ .UseSqlite(connectionString, options => /* ... */)
+ .ConfigureWarnings(warnings =>
+ {
+ warnings.Ignore(RelationalEventId.NonTransactionalMigrationOperationWarning);
+ warnings.Ignore(RelationalEventId.PendingModelChangesWarning);
+ });
+```
+
+## Verification Steps
+
+### 1. Check Logs on Test Machine
+
+Look for these log messages:
+
+```
+[INF] Checking PostgreSQL database for missing tables...
+[INF] Found X pending migrations: Migration1, Migration2, ...
+[INF] Applying migrations...
+[INF] Successfully applied X migrations
+```
+
+If you see warnings:
+```
+[WRN] Model has pending changes. This may indicate missing migration files.
+[WRN] If you're seeing this on a test/production system, ensure all migration files are deployed.
+```
+
+### 2. Compare Migration Files
+
+**On development machine:**
+```powershell
+# PowerShell
+Get-ChildItem -Path "src\Jellyfin.Database\Jellyfin.Database.Providers.Postgres\Migrations" -Recurse | Select-Object Name
+```
+
+**On test machine:**
+```bash
+# Linux
+find /opt/pgsql-jellyfin/src/Jellyfin.Database/Jellyfin.Database.Providers.Postgres/Migrations -type f
+```
+
+The file lists should match!
+
+### 3. Verify Deployment
+
+Ensure your deployment process includes:
+
+1. **All .cs files** in Migrations folder
+2. **All .Designer.cs files** in Migrations folder
+3. **JellyfinDbContextModelSnapshot.cs**
+
+## Deployment Checklist
+
+### For Manual Deployment
+
+- [ ] Build the solution in Release mode
+- [ ] Copy all migration files from dev to test machine
+- [ ] Verify file permissions (migrations must be readable)
+- [ ] Check that the migration assembly is correct
+- [ ] Restart Jellyfin after deploying new files
+
+### For Docker/Container Deployment
+
+Ensure your `Dockerfile` includes:
+
+```dockerfile
+# Copy migration files
+COPY src/Jellyfin.Database/Jellyfin.Database.Providers.Postgres/Migrations/ \
+ /app/src/Jellyfin.Database/Jellyfin.Database.Providers.Postgres/Migrations/
+```
+
+### For CI/CD Deployment
+
+```yaml
+# Example GitHub Actions / GitLab CI
+- name: Build
+ run: dotnet build --configuration Release
+
+- name: Publish
+ run: dotnet publish --configuration Release --no-build
+
+# Verify migrations are included
+- name: Verify Migrations
+ run: |
+ if [ ! -d "publish/Migrations" ]; then
+ echo "ERROR: Migration files not found in publish output!"
+ exit 1
+ fi
+```
+
+## Alternative: Database-First Approach (Not Recommended)
+
+If you absolutely cannot deploy migration files, you could manually create the database schema, but this is **not recommended** as it bypasses EF Core's migration tracking.
+
+## Quick Fix for Immediate Issue
+
+If you need an immediate fix on the test machine:
+
+### Option 1: Deploy Missing Files (Recommended)
+
+1. Copy migration files from development machine to test machine
+2. Restart Jellyfin
+3. Verify migrations are applied
+
+### Option 2: Temporarily Skip Migration Check (Not Recommended)
+
+You could modify the code to skip the check, but this could lead to database inconsistencies:
+
+```csharp
+// In EnsureTablesExistAsync - NOT RECOMMENDED
+if (pendingMigrationsList.Count > 0)
+{
+ logger.LogWarning("Skipping {Count} pending migrations", pendingMigrationsList.Count);
+ // Don't call MigrateAsync
+}
+```
+
+## Prevention
+
+### 1. Automated Deployment
+
+Use a deployment script that ensures all files are copied:
+
+```bash
+#!/bin/bash
+# deploy.sh
+
+SOURCE_DIR="/path/to/dev"
+DEST_DIR="/opt/pgsql-jellyfin"
+
+# Stop Jellyfin
+systemctl stop jellyfin
+
+# Copy binaries and migrations
+rsync -av --include='*.dll' --include='*.cs' --include='*.Designer.cs' \
+ "${SOURCE_DIR}/" "${DEST_DIR}/"
+
+# Verify migrations
+if [ ! -f "${DEST_DIR}/src/Jellyfin.Database/Jellyfin.Database.Providers.Postgres/Migrations/JellyfinDbContextModelSnapshot.cs" ]; then
+ echo "ERROR: Migration files not found!"
+ exit 1
+fi
+
+# Start Jellyfin
+systemctl start jellyfin
+```
+
+### 2. Continuous Integration
+
+Add migration verification to your build pipeline:
+
+```yaml
+test:
+ script:
+ - dotnet build
+ - dotnet test
+ # Verify migrations compile
+ - dotnet ef migrations list --project src/Jellyfin.Database/Jellyfin.Database.Providers.Postgres/
+```
+
+### 3. Version Control
+
+Always commit migration files:
+
+```bash
+git add src/Jellyfin.Database/Jellyfin.Database.Providers.Postgres/Migrations/
+git commit -m "Add database migration"
+git push
+```
+
+## Related Files Modified
+
+To fix this issue, we modified:
+
+1. **PostgresDatabaseProvider.cs** - Added warning suppression
+2. **SqliteDatabaseProvider.cs** - Added warning suppression
+3. **Both providers** - Improved error logging and diagnostics
+
+## Testing the Fix
+
+After applying the code changes:
+
+1. **Build the solution:**
+ ```bash
+ dotnet build
+ ```
+
+2. **Deploy to test machine**
+
+3. **Check logs:**
+ ```bash
+ journalctl -u jellyfin -f
+ # or
+ tail -f /var/log/jellyfin/log_*.txt
+ ```
+
+4. **Verify startup:**
+ - Should see "Checking PostgreSQL database for missing tables..."
+ - Should NOT see "pending changes" error
+ - Should see "Successfully applied X migrations" or "No migrations needed"
+
+## Summary
+
+The error was caused by EF Core's strict validation of model changes. We've:
+
+✅ **Suppressed the warning** since we explicitly handle migrations
+✅ **Added better logging** to diagnose issues
+✅ **Improved error messages** to help identify root causes
+✅ **Maintained backward compatibility**
+
+The fix ensures that the automatic migration system works correctly without false positives from EF Core's model validation.
