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

# 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:

./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

# 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:

# 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

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

// 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
