# VideoTools Cross-Platform Compatibility Guide

## Overview

VideoTools has been enhanced to provide seamless support for Arch Linux and Windows 11, with intelligent GUI detection and adaptive window sizing across both platforms.

## 🐧 Arch Linux Enhancements

### Installation Improvements

The `scripts/install.sh` script has been enhanced with:

#### GUI Environment Detection
- **Display Server Detection**: Automatically detects Wayland vs X11
- **Desktop Environment**: Detects GNOME, KDE, XFCE, i3, Sway
- **GPU Detection**: Identifies NVIDIA, AMD, Intel graphics cards
- **Driver Verification**: Checks if appropriate drivers are loaded

#### Enhanced Dependency Management
```bash
# The enhanced install function provides detailed feedback:
🔧 Detecting Arch Linux configuration...
   Display Server: Wayland detected
   Desktop Environment: GNOME
   GPU: NVIDIA detected - ensuring proper driver setup
   💡 Install NVIDIA drivers: sudo mhwd -a pci nonfree 0300
📦 Installing core packages...
   ✅ Arch Linux core dependencies installed
```

#### Package Installation
- **Core Dependencies**: FFmpeg, GStreamer with development headers
- **Display Server Specific**: Wayland protocols or X11 server packages
- **Desktop Environment Specific**: GNOME, KDE, XFCE packages when detectable
- **GPU Drivers**: Recommendations and verification for NVIDIA/AMD/Intel

### Testing

Run the test script to verify Arch Linux support:
```bash
./scripts/test-cross-platform.sh arch
```

## 🪟 Windows 11 Enhancements

### Native Installation (No WSL Required)

The `scripts/install-deps-windows.ps1` script now provides:

#### Windows 11 Detection
- **Build Number Detection**: Distinguishes Windows 11 (22000+) from Windows 10
- **Edition Detection**: Identifies Home, Pro, Education editions
- **Display Scaling**: Automatic DPI scaling detection
- **GPU Analysis**: Vendor, model, and DirectX 12 support detection

#### Enhanced PowerShell Functions
```powershell
# Get comprehensive Windows 11 information
$win11Info = Get-Windows11Info
$win11Info.IsWindows11          # boolean
$win11Info.DisplayScale         # e.g., 1.25, 1.5, 2.0
$win11Info.GPUInfo.Name       # e.g., "NVIDIA GeForce RTX 4070"
$win11Info.GPUInfo.SupportsDirectX12  # boolean
```

#### Native Dependency Installation
- **Chocolatey Integration**: Automatic installation and management
- **Native Dependencies**: FFmpeg, GStreamer, Go for Windows
- **GPU Optimization**: Vendor-specific driver recommendations
- **No WSL Dependency**: Pure Windows installation

### GPU Driver Recommendations
- **NVIDIA**: GeForce Experience updates, Game Ready Drivers
- **AMD**: Adrenalin Software updates
- **Intel**: Windows Update driver integration

### Testing

Run the test script to verify Windows 11 support:
```powershell
# From Git Bash (on Windows)
./scripts/test-cross-platform.sh windows

# From PowerShell
.\scripts\test-cross-platform.sh windows
```

## 🖥️ Cross-Platform GUI Detection

### New GUI Environment System

VideoTools now includes a comprehensive GUI detection system in `internal/utils/gui_detection.go`:

#### Platform Detection
```go
guiEnv := guitutils.DetectGUIEnvironment()
fmt.Printf("Display: %s, Desktop: %s, Scale: %.1fx, GPU: %s %s",
    guiEnv.DisplayServer, guiEnv.DesktopEnvironment, 
    guiEnv.ScaleFactor, guiEnv.GPUInfo.Vendor, guiEnv.GPUInfo.Model)
```

#### Supported Environments

| Platform | Display Server | Desktop | GPU Detection | Scaling |
|----------|----------------|----------|----------------|----------|
| Arch Linux | X11, Wayland | GNOME, KDE, XFCE, i3, Sway | ✅ | ✅ |
| Windows 11 | Windows Native | Windows 11 | ✅ | ✅ |
| macOS | Darwin | macOS | ✅ | ✅ |

### Adaptive Window Sizing

Windows automatically adapt to the detected environment:

#### Size Calculation Logic
```go
// Get optimal window size for current environment
optimalSize := guiEnv.GetOptimalWindowSize(800, 600)

// Module-specific sizing
playerSize := guiEnv.GetModuleSpecificSize("player")     // 1024x768 base
authorSize := guiEnv.GetModuleSpecificSize("author")     // 900x700 base
queueSize := guiEnv.GetModuleSpecificSize("queue")       // 700x500 base
```

#### Platform-Specific Adjustments
- **Windows 11**: Modern UI scaling, max 1600x1200
- **Wayland**: Good scaling support, max 1400x1000  
- **X11 High DPI**: Conservative scaling, max 1200x900
- **GPU Acceleration**: Disabled on very high DPI displays (>2.0x)

## 🧪 Testing Framework

### Comprehensive Test Script
