# GWEncoder v3.0 - Unified Video Encoding Tool

This is the consolidated version of all the encoding tools, providing a unified interface with multiple encoding modes.

## 🚀 Consolidation Summary

### What Was Consolidated:
- **gwemplate** - Fast AV1 encoder functionality → `--fast` mode
- **gwquick** - Command-line AV1 encoder → `--web`, `--quick`, `--tiny` modes  
- **GWEncoder.go** - Full interactive encoder → `--full` mode
- **GWRipper** - YouTube downloader (separate tool, minimal overlap)

### Code Reduction:
- **Before**: 4 separate tools, ~2,400 lines total
- **After**: 1 unified tool, ~800 lines (67% reduction)
- **Eliminated**: 1,000+ lines of duplicate code

## 🛠️ Building the Unified Tool

### Prerequisites:
```bash
# Install Go (if not already installed)
# Ubuntu/Debian:
sudo apt update
sudo apt install golang-go

# CentOS/RHEL:
sudo yum install golang

# macOS:
brew install go
```

### Build Commands:
```bash
# Navigate to the project directory
cd /home/user/Public/GWUTILZ

# Build the shared utilities package
cd gwutils
go build

# Build the unified encoder
cd ../gwencoder
go mod tidy
go build -o gwencoder main.go

# Make executable
chmod +x gwencoder
```

## 🎮 Usage

### Quick Start:
```bash
# Fast AV1 encoding (replaces gwemplate)
./gwencoder --fast

# Web-optimized encoding (replaces gwquick --web)
./gwencoder --web

# Quick encoding (replaces gwquick --quick)  
./gwencoder --quick

# Tiny file encoding (replaces gwquick --tiny)
./gwencoder --tiny

# Full interactive mode (replaces GWEncoder.go)
./gwencoder --full

# System information
./gwencoder --info

# Encoding statistics
./gwencoder --stats

# Help
./gwencoder --help
```

## 🎯 Encoding Modes

### `--fast` Mode (gwemplate functionality)
- **Purpose**: Fast AV1 encoding for quick results
- **Settings**: CRF 32, Preset 10, MKV container
- **Audio**: Opus 64kbps per channel
- **Use Case**: Quick local encoding

### `--web` Mode (gwquick web functionality)
- **Purpose**: Web-optimized encoding for streaming
- **Settings**: CRF 40, Preset 10, WEBM container
- **Audio**: Opus 64kbps per channel
- **Use Case**: Web uploads, social media

### `--quick` Mode (gwquick quick functionality)
- **Purpose**: Balanced quality and speed
- **Settings**: CRF 32, Preset 10, MKV container
- **Audio**: Opus 80kbps per channel
- **Use Case**: General purpose encoding

### `--tiny` Mode (gwquick tiny functionality)
- **Purpose**: Maximum compression
- **Settings**: CRF 45, Preset 8, MP4 container
- **Audio**: Opus 64kbps per channel
- **Use Case**: Storage optimization

### `--full` Mode (GWEncoder.go functionality)
- **Purpose**: Full interactive mode with all options
- **Features**: Multiple codecs, hardware acceleration, presets
- **Use Case**: Advanced users who need full control

## ⚙️ Features

### Shared Utilities (gwutils package):
- **Common Functions**: Duration detection, progress parsing, file operations
- **Unified Configuration**: Single JSON config structure
- **Progress Tracking**: Real-time encoding progress with ETA
- **File Operations**: Automatic media file detection
- **Error Handling**: Comprehensive error logging

### Encoding Features:
- **Multiple Codecs**: AV1 (primary), HEVC, H264, X265 support
- **Hardware Acceleration**: NVENC support for NVIDIA GPUs
- **Automatic Optimization**: CPU core detection and optimization
- **Progress Display**: Visual progress bars with ETA
- **Subtitle Handling**: Automatic subtitle extraction
- **Format Support**: MKV, MP4, WEBM containers

## 📊 Configuration

### Configuration File: `gwencoder_config.json`
```json
{
  "last_codec": "1",
  "last_audio_codec": "1", 
  "last_container": "1",
  "last_resolution": "original",
  "last_crf": "28",
  "last_preset": "medium",
  "last_bitrate": "2000",
  "extract_subtitles": true,
  "audio_bitrate": 64
}
```

### Log Files:
- `gwencoder_log.txt` - Successful encoding history
- `gwencoder_errors.txt` - Error logs for troubleshooting
- `gwencoder_stats.json` - Encoding statistics

## 🔧 Migration from Individual Tools

### From gwemplate:
```bash
# Old:
./gwemplate

# New:
./gwencoder --fast
```

### From gwquick:
```bash
# Old:
./gwenquick --web
./gwenquick --quick
./gwenquick --tiny

# New:

## 📈 Benefits of Consolidation

1. **Reduced Maintenance**: Single codebase to maintain instead of 4
2. **Consistent Behavior**: Same progress tracking, error handling across all modes
3. **Better Testing**: Test once, works everywhere
4. **Easier Feature Addition**: Add to one place, available everywhere
5. **Simplified Distribution**: Single binary with multiple modes
6. **Code Reuse**: Shared utilities eliminate 1,000+ lines of duplicate code

## 🚀 Future Enhancements

The unified structure makes it easy to add:
- New encoding modes
- Additional codec support
- GUI interface
- Batch processing improvements
- Cloud encoding support
- Plugin system

## 🤝 Contributing

The consolidated codebase makes contributions easier:
- Single codebase to understand
- Shared utilities reduce complexity
- Consistent patterns across all modes
- Better testing infrastructure
