# VNC Agent Bridge v0.2.0 - Feature Release Plan

**Version:** 0.2.0  
**Release Type:** Minor Feature Release  
**Estimated Duration:** 10-14 days  
**Release Date Target:** November 10, 2025  

---

## 📋 Executive Summary

Version 0.2.0 adds **screenshot capture**, **video recording**, and **clipboard management** capabilities to the VNC Agent Bridge package. This release transforms the package from a pure input control library into a comprehensive VNC automation toolkit.

### Key Features
- 📸 **Screenshot Capture**: Capture framebuffer at any point in time
- 🎥 **Video Recording**: Record screen sessions with configurable FPS
- 📋 **Clipboard Management**: Send/receive text via clipboard
- 🔄 **Framebuffer Updates**: Real-time screen content synchronization
- 🖼️ **Image Export**: Save screenshots as PNG, JPEG, BMP
- 🎬 **Video Export**: Export recordings to common formats

### Design Philosophy
- **Maintain Simplicity**: Keep the same easy-to-use API style
- **Optional Dependencies**: New features require optional dependencies
- **Backward Compatible**: All v0.1.0 code continues to work
- **Synchronous API**: Stay consistent with v0.1.0's sync approach
- **Type Safety**: Maintain 100% mypy strict compliance

## 📦 New Dependencies

### Required for New Features
```toml
[project.optional-dependencies]
capture = [
    "numpy>=1.20.0",      # Framebuffer array manipulation
    "Pillow>=9.0.0",      # Image saving (PNG, JPEG, BMP)
]
video = [
    "numpy>=1.20.0",      # Frame data handling
    "Pillow>=9.0.0",      # Frame-to-image conversion
]
full = [
    "numpy>=1.20.0",      # All features
    "Pillow>=9.0.0",      # All features
]
```

### Installation Options
```bash
# Base package (v0.1.0 features only)
pip install vnc-agent-bridge

# With screenshot support
pip install vnc-agent-bridge[capture]

# With video recording support
pip install vnc-agent-bridge[video]

# With all features
pip install vnc-agent-bridge[full]

# Development (all features + dev tools)
pip install vnc-agent-bridge[full,dev]
```

### Dependency Rationale
- **numpy**: Industry standard for efficient array/image operations
- **Pillow**: Pure Python image library, widely used, no C dependencies required
- **No video codec libraries**: Initial version saves frame sequences, not encoded video

## 🔄 Backward Compatibility

### Compatibility Guarantees
1. **All v0.1.0 APIs unchanged**: Mouse, keyboard, scroll controllers work exactly the same
2. **Optional dependencies**: New features require opt-in installation
3. **Same import structure**: `from vnc_agent_bridge import VNCAgentBridge`
4. **No breaking changes**: Existing code runs without modifications

### Migration Path
```python
# v0.1.0 code (still works in v0.2.0)
from vnc_agent_bridge import VNCAgentBridge

with VNCAgentBridge('localhost') as vnc:
    vnc.mouse.left_click(100, 100)
    vnc.keyboard.type_text("Hello")

# v0.2.0 new features (requires optional dependencies)
with VNCAgentBridge('localhost') as vnc:
    # Existing features
    vnc.mouse.left_click(100, 100)
    
    # New features
    vnc.screenshot.save('screen.png')
    vnc.clipboard.send_text("Hello")
```

## 📋 Risk Assessment

### High Risk
1. **Dependency bloat**: Adding numpy/Pillow increases install size
   - **Mitigation**: Make dependencies optional, clear documentation
   
2. **Performance issues**: Video recording at high FPS
   - **Mitigation**: Thorough performance testing, optimization
   
3. **Memory leaks**: Long recordings accumulate frames
   - **Mitigation**: Memory profiling, frame cleanup strategies

### Medium Risk
1. **Encoding compatibility**: Not all VNC servers support all encodings
   - **Mitigation**: Support most common encodings, clear error messages
   
2. **Threading complexity**: Background video recording
   - **Mitigation**: Use threading.Thread, proper synchronization

3. **Image format issues**: Different PIL versions
   - **Mitigation**: Test with multiple Pillow versions

### Low Risk
1. **Clipboard encoding**: Different text encodings
   - **Mitigation**: Handle UTF-8 and latin-1, fallback logic
   
2. **Documentation completeness**: Many new features to document
   - **Mitigation**: Allocate sufficient time, review process

## 🎓 Example Usage Scenarios

### Scenario 1: Automated Testing with Screenshots
```python
from vnc_agent_bridge import VNCAgentBridge

with VNCAgentBridge('test-server') as vnc:
    # Navigate to login page
    vnc.mouse.left_click(100, 50)  # Click URL bar
    vnc.keyboard.type_text("http://app.test/login")
    vnc.keyboard.press_key('return')
    
    # Wait for page load and capture
    vnc.screenshot.save('1_login_page.png', delay=2.0)
    
    # Enter credentials
    vnc.mouse.left_click(200, 150)  # Username field
    vnc.keyboard.type_text("testuser")
    vnc.screenshot.save('2_username_entered.png')
    
    vnc.keyboard.press_key('tab')  # Move to password
    vnc.keyboard.type_text("password123")
    vnc.screenshot.save('3_password_entered.png')
    
    # Submit and capture result
    vnc.keyboard.press_key('return')
    vnc.screenshot.save('4_login_result.png', delay=1.0)
```

### Scenario 2: Video Recording of User Workflow
```python
from vnc_agent_bridge import VNCAgentBridge

with VNCAgentBridge('demo-server') as vnc:
    # Start recording
    vnc.video.start_recording(fps=30.0)
    
    # Perform workflow
    vnc.mouse.left_click(50, 50)  # Open menu
    vnc.keyboard.type_text("New Document")
    vnc.keyboard.press_key('return')
    
    # Type some content
    vnc.keyboard.type_text("This is a demo document.")
    
    # Save document
    vnc.keyboard.hotkey('ctrl', 's')
    vnc.keyboard.type_text("demo.txt")
    vnc.keyboard.press_key('return')
    
    # Stop recording and save
    frames = vnc.video.stop_recording()
    vnc.video.save_frames(frames, 'workflow_recording/')
    
    print(f"Recorded {len(frames)} frames")
    print(f"Duration: {vnc.video.get_duration(frames):.2f}s")
```

### Scenario 3: Clipboard-Based Data Transfer
```python
from vnc_agent_bridge import VNCAgentBridge
import json

with VNCAgentBridge('data-server') as vnc:
    # Send structured data via clipboard
    data = {
        "name": "John Doe",
        "email": "john@example.com",
        "age": 30
    }
    
    # Convert to JSON and send
    json_text = json.dumps(data, indent=2)
    vnc.clipboard.send_text(json_text)
    
    # Paste into application
    vnc.mouse.left_click(300, 200)  # Click text area
    vnc.keyboard.hotkey('ctrl', 'v')
    
    # Capture result
    vnc.screenshot.save('data_pasted.png', delay=0.5)
```

### Scenario 4: Advanced Monitoring with Conditional Recording
```python
from vnc_agent_bridge import VNCAgentBridge
import numpy as np

with VNCAgentBridge('monitor-server') as vnc:
    def error_detected():
        # Capture current screen
        screenshot = vnc.screenshot.capture()
        
        # Simple color-based detection (example)
        # Check for red error dialogs
        red_channel = screenshot[:, :, 0]
        red_percentage = np.mean(red_channel > 200)
        
        return red_percentage > 0.1  # 10% red pixels
    
    # Record until error appears (max 60 seconds)
    frames = vnc.video.record_until(
        condition=error_detected,
        max_duration=60.0,
        fps=15.0  # Lower FPS for monitoring
    )
    
    if len(frames) > 0:
        # Error detected, save recording
        vnc.video.save_frames(frames, 'error_recording/')
        
        # Also save final screenshot
        vnc.screenshot.save('error_screenshot.png')
        
        print(f"Error detected after {frames[-1].timestamp:.2f}s")
```

## 📝 Notes and Considerations

### Design Decisions

1. **Synchronous API**: Stay consistent with v0.1.0, async support can be added in v0.3.0
2. **Optional Dependencies**: Don't force users to install numpy/Pillow if they only need input control
3. **No Video Encoding**: Initial version saves frame sequences, video encoding can be added in v0.3.0
4. **PIL over OpenCV**: Pillow is pure Python, lighter weight, sufficient for our needs
5. **Threading over Asyncio**: Simpler for synchronous API, consistent with current design

### Future Enhancements (v0.3.0+)

- Async/await support for all operations
- Video encoding (H.264, WebM, etc.)
- Audio capture (if VNC server supports)
- OCR integration for text recognition
- Object detection integration
- Region-based frame difference detection
- Adaptive FPS based on screen changes
- Compressed frame storage
- Streaming support (websockets, RTSP)

### Known Limitations

1. **No Audio**: VNC protocol doesn't include audio
2. **Performance**: Video recording is CPU-intensive at high FPS
3. **Memory**: Long recordings consume significant memory
4. **Encoding**: Limited to Raw, CopyRect, RRE, Hextile, ZRLE initially
5. **Clipboard**: Text only, no rich formats initially
