7. Prompt() - User input
8. GetVideoInfo() - Video information extraction
9. GetPhysicalCores() - CPU core detection
10. CheckFFmpeg() / CheckFFprobe() - Dependency checking

🎮 Unified Interface

Old Usage (4 separate tools):

./gwemplate                    # Fast AV1 encoding
./gwenquick --web              # Web-optimized encoding
./gwenquick --quick            # Quick encoding
./gwenquick --tiny             # Tiny file encoding
./gwencode_v2                  # Full interactive mode
./gwripper                     # YouTube downloading

New Usage (1 unified tool):

./gwencoder --fast             # Fast AV1 encoding (gwemplate)
./gwencoder --web              # Web-optimized encoding (gwquick --web)
./gwencoder --quick            # Quick encoding (gwquick --quick)
./gwencoder --tiny             # Tiny file encoding (gwquick --tiny)
./gwencoder --full             # Full interactive mode (GWEncoder.go)
./gwencoder --help             # Help information
./gwencoder --info             # System information
./gwencoder --stats            # Encoding statistics

📁 Shared Utilities Package (gwutils)

Common Functions (common.go):

• GetVideoDuration() - Extract video duration using ffprobe
• ParseFFmpegProgress() - Parse FFmpeg progress output
• FormatTime() - Convert seconds to HH:MM:SS format
• GetAudioBitrate() - Calculate audio bitrate based on channels
• FindMediaFiles() - Find media files with exclusion patterns
• AppendToFile() - Append text to log files
• Prompt() - User input with defaults
• GetVideoInfo() - Get video resolution and codec info
• GetPhysicalCores() - Calculate physical CPU cores
• CheckFFmpeg() / CheckFFprobe() - Check tool availability

Configuration (config.go):

• Config struct - Unified configuration structure
• EncodingMode struct - Encoding mode definitions
• Preset struct - Preset definitions
• ProgressTracker struct - Progress tracking
• LoadConfig() / SaveConfig() - Configuration management
• GetDefaultPresets() / GetDefaultModes() - Default settings

🎯 Encoding Modes Available

--fast Mode (gwemplate functionality)
