# Instructions for AI Agent: Auto-Recording Feature Integration
## 🎯 Task Overview
Update the React application to support the new auto-recording feature that has been added to the USDA Vision Camera System backend.
## 📋 What You Need to Know
### System Context
- **Camera 1** monitors the **vibratory conveyor** (conveyor/cracker cam)
- **Camera 2** monitors the **blower separator** machine
- Auto-recording automatically starts when machines turn ON and stops when they turn OFF
- The system includes retry logic for failed recording attempts
- Manual recording always takes precedence over auto-recording
### New Backend Capabilities
The backend now supports:
1. **Automatic recording** triggered by MQTT machine state changes
2. **Retry mechanism** for failed recording attempts (configurable retries and delays)
3. **Status tracking** for auto-recording state, failures, and attempts
4. **API endpoints** for enabling/disabling and monitoring auto-recording
## 🔧 Required React App Changes
### 1. Update TypeScript Interfaces
Add these new fields to existing `CameraStatusResponse`:
```typescript
interface CameraStatusResponse {
// ... existing fields
auto_recording_enabled: boolean;
auto_recording_active: boolean;
auto_recording_failure_count: number;
auto_recording_last_attempt?: string;
auto_recording_last_error?: string;
}
```
Add new response types:
```typescript
interface AutoRecordingConfigResponse {
success: boolean;
message: string;
camera_name: string;
enabled: boolean;
}
interface AutoRecordingStatusResponse {
running: boolean;
auto_recording_enabled: boolean;
retry_queue: Record<string, any>;
enabled_cameras: string[];
}
```
### 2. Add New API Endpoints
```typescript
// Enable auto-recording for a camera
POST /cameras/{camera_name}/auto-recording/enable
// Disable auto-recording for a camera
POST /cameras/{camera_name}/auto-recording/disable
// Get overall auto-recording system status
GET /auto-recording/status
```
### 3. UI Components to Add/Update
#### Camera Status Display
- Add auto-recording status badge/indicator
- Show auto-recording enabled/disabled state
- Display failure count if > 0
- Show last error message if any
- Distinguish between manual and auto-recording states
#### Auto-Recording Controls
- Toggle switch to enable/disable auto-recording per camera
- System-wide auto-recording status display
- Retry queue information
- Machine state correlation display
#### Error Handling
- Clear display of auto-recording failures
- Retry attempt information
- Last attempt timestamp
- Quick retry/reset actions
### 4. Visual Design Guidelines
**Status Priority (highest to lowest):**
1. Manual Recording (red/prominent) - user initiated
2. Auto-Recording Active (green) - machine ON, recording
3. Auto-Recording Enabled (blue) - ready but machine OFF
4. Auto-Recording Disabled (gray) - feature disabled
**Machine Correlation:**
- Show machine name next to camera (e.g., "Vibratory Conveyor", "Blower Separator")
- Display machine ON/OFF status
- Alert if machine is ON but auto-recording failed
## 🎨 Specific Implementation Tasks
### Task 1: Update Camera Cards
- Add auto-recording status indicators
- Add enable/disable toggle controls
- Show machine state correlation
- Display failure information when relevant
### Task 2: Create Auto-Recording Dashboard
- Overall system status
- List of enabled cameras
- Active retry queue display
- Recent events/errors
### Task 3: Update Recording Status Logic
- Distinguish between manual and auto-recording
- Show appropriate controls based on recording type
- Handle manual override scenarios
### Task 4: Add Error Handling
- Display auto-recording failures clearly
- Show retry attempts and timing
- Provide manual retry options
## 📱 User Experience Requirements
### Key Behaviors
1. **Non-Intrusive:** Auto-recording status shouldn't clutter the main interface
2. **Clear Hierarchy:** Manual controls should be more prominent than auto-recording
3. **Informative:** Users should understand why recording started/stopped
4. **Actionable:** Clear options to enable/disable or retry failed attempts
### Mobile Considerations
- Auto-recording controls should work well on mobile
- Status information should be readable on small screens
- Consider collapsible sections for detailed information
## 🔍 Testing Requirements
Ensure the React app correctly handles:
- [ ] Toggling auto-recording on/off per camera
- [ ] Displaying real-time status updates
- [ ] Showing error states and retry information
- [ ] Manual recording override scenarios
- [ ] Machine state changes and correlation
- [ ] Mobile interface functionality
## 📚 Reference Files
Key files to review for implementation details:
- `AUTO_RECORDING_FEATURE_GUIDE.md` - Comprehensive technical details
- `api-endpoints.http` - API endpoint documentation
- `config.json` - Configuration structure
- `usda_vision_system/api/models.py` - Response type definitions
## 🎯 Success Criteria
The React app should:
1. **Display** auto-recording status for each camera clearly
2. **Allow** users to enable/disable auto-recording per camera
3. **Show** machine state correlation and recording triggers
4. **Handle** error states and retry scenarios gracefully
5. **Maintain** existing manual recording functionality
6. **Provide** clear visual hierarchy between manual and auto-recording
## 💡 Implementation Tips
1. **Start Small:** Begin with basic status display, then add controls
2. **Use Existing Patterns:** Follow the current app's design patterns
3. **Test Incrementally:** Test each feature as you add it
4. **Consider State Management:** Update your state management to handle new data
5. **Mobile First:** Ensure mobile usability from the start
The goal is to seamlessly integrate auto-recording capabilities while maintaining the existing user experience and adding valuable automation features for the camera operators.

};
```
## 🔧 Configuration Options
### Environment Variables (.env)
```env
# Production configuration (using 'vision' hostname)
REACT_APP_CAMERA_API_URL=http://vision:8000
REACT_APP_STREAM_REFRESH_INTERVAL=30000
REACT_APP_STREAM_TIMEOUT=10000
# Development configuration (using localhost)
# REACT_APP_CAMERA_API_URL=http://vision:8000
# Custom IP configuration
# REACT_APP_CAMERA_API_URL=http://192.168.1.100:8000
```
### API Configuration
```javascript
const apiConfig = {
baseUrl: process.env.REACT_APP_CAMERA_API_URL || 'http://vision:8000',
timeout: parseInt(process.env.REACT_APP_STREAM_TIMEOUT) || 10000,
refreshInterval: parseInt(process.env.REACT_APP_STREAM_REFRESH_INTERVAL) || 30000,
};
```
### Hostname Setup Guide
```bash
# Option 1: Add to /etc/hosts (Linux/Mac)
echo "127.0.0.1 vision" | sudo tee -a /etc/hosts
# Option 2: Add to hosts file (Windows)
# Add to C:\Windows\System32\drivers\etc\hosts:
# 127.0.0.1 vision
# Option 3: Configure DNS
# Point 'vision' hostname to your server's IP address
# Verify hostname resolution
ping vision
```
## 🚨 Important Implementation Notes
### 1. MJPEG Stream Handling
- Use HTML `<img>` tag with `src` pointing to stream endpoint
- Add timestamp query parameter to prevent caching: `?t=${Date.now()}`
- Handle `onError` event for connection issues
### 2. Error Handling
- Network errors (fetch failures)
- HTTP errors (4xx, 5xx responses)
- Stream connection errors (img onError)
- Timeout handling for long requests
### 3. Performance Considerations
- Streams consume bandwidth continuously
- Stop streams when components unmount
- Limit concurrent streams based on system capacity
- Consider lazy loading for multiple cameras
### 4. State Management
- Track streaming state per camera
- Handle loading states during API calls
- Manage error states with user feedback
- Refresh camera list periodically
## 📱 Mobile Considerations
```jsx
// Responsive design for mobile
const mobileStyles = {
container: {
padding: '10px',
maxWidth: '100vw',
},
stream: {
width: '100%',
maxWidth: '100vw',
height: 'auto',
},
controls: {
display: 'flex',
flexDirection: 'column',
gap: '8px',
},
};
```
## 🧪 Testing Integration
```javascript
// Test API connectivity
const testConnection = async () => {
try {
const response = await fetch(`${apiBaseUrl}/health`);
return response.ok;
} catch {
return false;
}
};
// Test camera availability
const testCamera = async (cameraName) => {
try {
const response = await fetch(`${apiBaseUrl}/cameras/${cameraName}/test-connection`, {
method: 'POST',
});
return response.ok;
} catch {
return false;
}
};
```

3. **Get Auto-Recording Status**
```http
GET /auto-recording/status
Response: AutoRecordingStatusResponse
```
### Updated API Responses
#### CameraStatusResponse (Updated)
```typescript
interface CameraStatusResponse {
name: string;
status: string;
is_recording: boolean;
last_checked: string;
last_error?: string;
device_info?: any;
current_recording_file?: string;
recording_start_time?: string;
// NEW AUTO-RECORDING FIELDS
auto_recording_enabled: boolean;
auto_recording_active: boolean;
auto_recording_failure_count: number;

storage_path: string;
enabled: boolean;
// NEW AUTO-RECORDING CONFIG FIELDS
auto_start_recording_enabled: boolean;
auto_recording_max_retries: number;
auto_recording_retry_delay_seconds: number;
// ... existing fields (exposure_ms, gain, etc.)
}
```
#### New Response Types
```typescript
interface AutoRecordingConfigResponse {
success: boolean;
message: string;
camera_name: string;
enabled: boolean;
}
interface AutoRecordingStatusResponse {
running: boolean;
auto_recording_enabled: boolean;
retry_queue: Record<string, any>;
enabled_cameras: string[];
}
```
## 🎨 React App UI Requirements
### 1. Camera Status Display Updates
**Add to Camera Cards/Components:**
- Auto-recording enabled/disabled indicator
- Auto-recording active status (when machine is ON and auto-recording)
- Failure count display (if > 0)
- Last auto-recording error (if any)
- Visual distinction between manual and auto-recording
**Example UI Elements:**
```jsx
// Auto-recording status badge
{camera.auto_recording_enabled && (
<Badge variant={camera.auto_recording_active ? "success" : "secondary"}>
Auto-Recording {camera.auto_recording_active ? "Active" : "Enabled"}
</Badge>
)}
// Failure indicator
{camera.auto_recording_failure_count > 0 && (
<Alert variant="warning">
Auto-recording failures: {camera.auto_recording_failure_count}
</Alert>
)}
```
### 2. Auto-Recording Controls
**Add Toggle Controls:**
- Enable/Disable auto-recording per camera
- Global auto-recording status display
- Retry queue monitoring
**Example Control Component:**
```jsx
const AutoRecordingToggle = ({ camera, onToggle }) => {
const handleToggle = async () => {
const endpoint = camera.auto_recording_enabled ? 'disable' : 'enable';
await fetch(`/cameras/${camera.name}/auto-recording/${endpoint}`, {
method: 'POST'
});
onToggle();
};
return (
<Switch
checked={camera.auto_recording_enabled}
onChange={handleToggle}
label="Auto-Recording"
/>
);
};
```
### 3. Machine State Integration
**Display Machine Status:**
- Show which machine each camera monitors
- Display current machine state (ON/OFF)
- Show correlation between machine state and recording status
**Camera-Machine Mapping:**
- Camera 1 → Vibratory Conveyor (conveyor/cracker cam)
- Camera 2 → Blower Separator (blower separator)
### 4. Auto-Recording Dashboard
**Create New Dashboard Section:**
- Overall auto-recording system status
- List of cameras with auto-recording enabled
- Active retry queue display
- Recent auto-recording events/logs
## 🔧 Implementation Steps for React App
### Step 1: Update TypeScript Interfaces
```typescript
// Update existing interfaces in your types file
// Add new interfaces for auto-recording responses
```
### Step 2: Update API Service Functions
```typescript
// Add new API calls
export const enableAutoRecording = (cameraName: string) =>
fetch(`/cameras/${cameraName}/auto-recording/enable`, { method: 'POST' });
export const disableAutoRecording = (cameraName: string) =>
fetch(`/cameras/${cameraName}/auto-recording/disable`, { method: 'POST' });
export const getAutoRecordingStatus = () =>
fetch('/auto-recording/status').then(res => res.json());
```
### Step 3: Update Camera Components
- Add auto-recording status indicators
- Add enable/disable controls
- Update recording status display to distinguish auto vs manual
### Step 4: Create Auto-Recording Management Panel
- System-wide auto-recording status
- Per-camera auto-recording controls
- Retry queue monitoring
- Error reporting and alerts
### Step 5: Update State Management
```typescript
// Add auto-recording state to your store/context
interface AppState {
cameras: CameraStatusResponse[];
autoRecordingStatus: AutoRecordingStatusResponse;
// ... existing state
}
```
## 🎯 Key User Experience Considerations
### Visual Indicators
1. **Recording Status Hierarchy:**
- Manual Recording (highest priority - red/prominent)
- Auto-Recording Active (green/secondary)
- Auto-Recording Enabled but Inactive (blue/subtle)
- Auto-Recording Disabled (gray/muted)
2. **Machine State Correlation:**
- Show machine ON/OFF status next to camera
- Indicate when auto-recording should be active
- Alert if machine is ON but auto-recording failed
3. **Error Handling:**
- Clear error messages for auto-recording failures
- Retry count display
- Last attempt timestamp
- Quick retry/reset options
### User Controls
1. **Quick Actions:**
- Toggle auto-recording per camera
- Force retry failed auto-recording
- Override auto-recording (manual control)
2. **Configuration:**
- Adjust retry settings
- Change machine-camera mappings
- Set recording parameters for auto-recording
## 🚨 Important Notes
### Behavior Rules
1. **Manual Override:** Manual recording always takes precedence over auto-recording
2. **Non-Blocking:** Auto-recording status checks don't interfere with camera operation
3. **Machine Correlation:** Auto-recording only activates when the associated machine turns ON
4. **Failure Handling:** Failed auto-recording attempts are retried automatically with exponential backoff
### API Polling Recommendations
- Poll camera status every 2-3 seconds for real-time updates
- Poll auto-recording status every 5-10 seconds
- Use WebSocket connections if available for real-time machine state updates
## 📱 Mobile Considerations
- Auto-recording controls should be easily accessible on mobile
- Status indicators should be clear and readable on small screens
- Consider collapsible sections for detailed auto-recording information
## 🔍 Testing Checklist
- [ ] Auto-recording toggle works for each camera
- [ ] Status updates reflect machine state changes
- [ ] Error states are clearly displayed
- [ ] Manual recording overrides auto-recording
- [ ] Retry mechanism is visible to users
- [ ] Mobile interface is functional
This guide provides everything needed to update the React app to fully support the new auto-recording feature!

# 🎛️ Camera Configuration API Guide
This guide explains how to configure camera settings via API endpoints, including all the advanced settings from your config.json.
## 📋 Configuration Categories
### ✅ **Real-time Configurable (No Restart Required)**
These settings can be changed while the camera is active:
- **Basic**: `exposure_ms`, `gain`, `target_fps`
- **Image Quality**: `sharpness`, `contrast`, `saturation`, `gamma`
- **Color**: `auto_white_balance`, `color_temperature_preset`
- **Advanced**: `anti_flicker_enabled`, `light_frequency`
- **HDR**: `hdr_enabled`, `hdr_gain_mode`
### ⚠️ **Restart Required**
These settings require camera restart to take effect:
- **Noise Reduction**: `noise_filter_enabled`, `denoise_3d_enabled`
- **System**: `machine_topic`, `storage_path`, `enabled`, `bit_depth`
### 🤖 **Auto-Recording**
- **Auto-Recording**: `auto_record_on_machine_start` - When enabled, the camera automatically starts recording when MQTT messages indicate the associated machine turns on, and stops recording when it turns off

## 🔄 Configuration Workflow
### 1. Real-time Adjustments
For settings that don't require restart:
```bash
# Update settings
curl -X PUT /cameras/camera1/config -d '{"exposure_ms": 2.0}'
# Settings take effect immediately
# Continue recording/streaming without interruption
```
### 2. Settings Requiring Restart
For noise reduction and system settings:
```bash
# Update settings
curl -X PUT /cameras/camera1/config -d '{"noise_filter_enabled": false}'
# Apply configuration (restarts camera)
curl -X POST /cameras/camera1/apply-config
# Camera reinitializes with new settings
```
## 🚨 Important Notes
### Camera State During Updates
- **Real-time settings**: Applied immediately, no interruption
- **Restart-required settings**: Saved to config, applied on next restart
- **Recording**: Continues during real-time updates
- **Streaming**: Continues during real-time updates
### Error Handling
- Invalid ranges return HTTP 422 with validation errors
- Camera not found returns HTTP 404
- SDK errors are logged and return HTTP 500
### Performance Impact
- **Image quality settings**: Minimal performance impact
- **Noise reduction**: May reduce FPS when enabled
- **HDR**: Significant processing overhead when enabled
This comprehensive API allows you to control all camera settings programmatically, making it perfect for integration with React dashboards or automated optimization systems!

# USDA Vision Camera System
A comprehensive system for monitoring machines via MQTT and automatically recording video from GigE cameras when machines are active. Designed for Atlanta, Georgia operations with proper timezone synchronization.
## 🎯 Overview
This system integrates MQTT machine monitoring with automated video recording from GigE cameras. When a machine turns on (detected via MQTT), the system automatically starts recording from the associated camera. When the machine turns off, recording stops and the video is saved with an Atlanta timezone timestamp.
### Key Features
- **🔄 MQTT Integration**: Listens to multiple machine state topics
- **📹 Automatic Recording**: Starts/stops recording based on machine states
- **📷 GigE Camera Support**: Uses camera SDK library (mvsdk) for camera control
- **⚡ Multi-threading**: Concurrent MQTT listening, camera monitoring, and recording
- **🌐 REST API**: FastAPI server for dashboard integration
- **📡 WebSocket Support**: Real-time status updates
- **💾 Storage Management**: Organized file storage with cleanup capabilities
- **📝 Comprehensive Logging**: Detailed logging with rotation and error tracking
- **⚙️ Configuration Management**: JSON-based configuration system
- **🕐 Timezone Sync**: Proper time synchronization for Atlanta, Georgia

**Problem**: `Camera discovery failed` or `No cameras found`
**Solutions**:
```bash
# Check camera connections
ping 192.168.1.165 # Replace with your camera IP
# Verify camera SDK library
ls -la "camera_sdk/"
# Should contain mvsdk.py and related files
# Test camera discovery manually
python -c "
import sys; sys.path.append('./camera_sdk')
import mvsdk
devices = mvsdk.CameraEnumerateDevice()
print(f'Found {len(devices)} cameras')
for i, dev in enumerate(devices):
print(f'Camera {i}: {dev.GetFriendlyName()}')
"
# Check camera permissions
sudo chmod 666 /dev/video* # If using USB cameras
```
#### 2. MQTT Connection Failed
**Problem**: `MQTT connection failed` or `MQTT disconnected`
**Solutions**:
```bash
# Test MQTT broker connectivity
ping 192.168.1.110 # Replace with your broker IP
telnet 192.168.1.110 1883 # Test port connectivity
# Test MQTT manually
mosquitto_sub -h 192.168.1.110 -t "vision/+/state" -v
# Check credentials in config.json
{
"mqtt": {
"broker_host": "192.168.1.110",
"broker_port": 1883,
"username": "your_username", # Add if required
"password": "your_password" # Add if required
}
}
# Check firewall
sudo ufw status
sudo ufw allow 1883 # Allow MQTT port
```
#### 3. Recording Fails
**Problem**: `Failed to start recording` or `Camera initialization failed`
**Solutions**:
```bash
# Check storage permissions
ls -la storage/
chmod 755 storage/
chmod 755 storage/camera*/
# Check available disk space
df -h storage/
# Test camera initialization
python -c "
import sys; sys.path.append('./camera_sdk')
import mvsdk
devices = mvsdk.CameraEnumerateDevice()
if devices:
try:
hCamera = mvsdk.CameraInit(devices[0], -1, -1)
print('Camera initialized successfully')
mvsdk.CameraUnInit(hCamera)
except Exception as e:
print(f'Camera init failed: {e}')
"
# Check if camera is busy
lsof | grep video # Check what's using cameras
```
#### 4. API Server Won't Start
**Problem**: `Failed to start API server` or `Port already in use`
**Solutions**:
```bash
# Check if port 8000 is in use
netstat -tlnp | grep 8000
lsof -i :8000
# Kill process using port 8000
sudo kill -9 $(lsof -t -i:8000)
# Use different port in config.json
{
"system": {
"api_port": 8001 # Change port
}
}
# Check firewall
sudo ufw allow 8000
```
#### 5. Time Synchronization Issues
**Problem**: `Time is NOT synchronized` or time drift warnings
**Solutions**:
```bash
# Check time sync status
timedatectl status
# Force time sync
sudo systemctl restart systemd-timesyncd
sudo timedatectl set-ntp true
# Manual time sync
sudo ntpdate -s time.nist.gov
# Check timezone
timedatectl list-timezones | grep New_York
sudo timedatectl set-timezone America/New_York
# Verify with system
python check_time.py
```
#### 6. Storage Issues
**Problem**: `Permission denied` or `No space left on device`
**Solutions**:
```bash
# Check disk space
df -h
du -sh storage/
# Fix permissions
sudo chown -R $USER:$USER storage/
chmod -R 755 storage/
# Clean up old files
python -c "
from usda_vision_system.storage.manager import StorageManager
from usda_vision_system.core.config import Config
from usda_vision_system.core.state_manager import StateManager
config = Config()
state_manager = StateManager()
storage = StorageManager(config, state_manager)
result = storage.cleanup_old_files(7) # Clean files older than 7 days
print(f'Cleaned {result[\"files_removed\"]} files')
"
```
### Debug Mode
Enable debug mode for detailed troubleshooting:
```bash
# Start with debug logging
python main.py --log-level DEBUG
# Check specific component logs
tail -f usda_vision_system.log | grep "camera"
tail -f usda_vision_system.log | grep "mqtt"

# 🎥 USDA Vision Camera Live Streaming Guide
This guide explains how to use the new live preview streaming functionality that allows you to view camera feeds in real-time without blocking recording operations.
## 🌟 Key Features
- **Non-blocking streaming**: Live preview doesn't interfere with recording
- **Separate camera connections**: Streaming uses independent camera instances
- **MJPEG streaming**: Standard web-compatible video streaming
- **Multiple concurrent viewers**: Multiple browsers can view the same stream
- **REST API control**: Start/stop streaming via API endpoints
- **Web interface**: Ready-to-use HTML interface for live preview
## 🏗️ Architecture
The streaming system creates separate camera connections for preview that are independent from recording:
```
Camera Hardware
├── Recording Connection (CameraRecorder)
│ ├── Used for video file recording
│ ├── Triggered by MQTT machine states
│ └── High quality, full FPS
└── Streaming Connection (CameraStreamer)
├── Used for live preview
├── Controlled via API endpoints
└── Optimized for web viewing (lower FPS, JPEG compression)
```
## 🚀 Quick Start
### 1. Start the System
```bash
python main.py
```
### 2. Open the Web Interface
Open `camera_preview.html` in your browser and click "Start Stream" for any camera.
### 3. API Usage
```bash
# Start streaming for camera1
curl -X POST http://vision:8000/cameras/camera1/start-stream
# View live stream (open in browser)
http://vision:8000/cameras/camera1/stream
# Stop streaming
curl -X POST http://vision:8000/cameras/camera1/stop-stream
```
## 📡 API Endpoints
### Start Streaming
```http
POST /cameras/{camera_name}/start-stream
```
**Response:**
```json
{
"success": true,
"message": "Started streaming for camera camera1"
}
```
### Stop Streaming
```http
POST /cameras/{camera_name}/stop-stream
```
**Response:**
```json
{
"success": true,
"message": "Stopped streaming for camera camera1"
}
```
### Live Stream (MJPEG)
```http
GET /cameras/{camera_name}/stream
```
**Response:** Multipart MJPEG stream
**Content-Type:** `multipart/x-mixed-replace; boundary=frame`
## 🌐 Web Interface Usage
The included `camera_preview.html` provides a complete web interface:
1. **Camera Grid**: Shows all configured cameras
2. **Stream Controls**: Start/Stop/Refresh buttons for each camera
3. **Live Preview**: Real-time video feed display
4. **Status Information**: System and camera status
5. **Responsive Design**: Works on desktop and mobile
### Features:
- ✅ Real-time camera status
- ✅ One-click stream start/stop
- ✅ Automatic stream refresh
- ✅ System health monitoring
- ✅ Error handling and status messages
## 🔧 Technical Details
### Camera Streamer Configuration
- **Preview FPS**: 10 FPS (configurable)
- **JPEG Quality**: 70% (configurable)
- **Frame Buffer**: 5 frames (prevents memory buildup)
- **Timeout**: 200ms per frame capture
### Memory Management
- Automatic frame buffer cleanup
- Queue-based frame management
- Proper camera resource cleanup on stop
### Thread Safety
- Thread-safe streaming operations
- Independent from recording threads
- Proper synchronization with locks
## 🧪 Testing
### Run the Test Script
```bash
python test_streaming.py
```
This will test:
- ✅ API endpoint functionality
- ✅ Stream start/stop operations
- ✅ Concurrent recording and streaming
- ✅ Error handling
### Manual Testing
1. Start the system: `python main.py`
2. Open `camera_preview.html` in browser
3. Start streaming for a camera
4. Trigger recording via MQTT or manual API
5. Verify both work simultaneously
## 🔄 Concurrent Operations
The system supports these concurrent operations:
| Operation | Recording | Streaming | Notes |
|-----------|-----------|-----------|-------|
| Recording Only | ✅ | ❌ | Normal operation |
| Streaming Only | ❌ | ✅ | Preview without recording |
| Both Concurrent | ✅ | ✅ | **Independent connections** |
### Example: Concurrent Usage
```bash
# Start streaming
curl -X POST http://vision:8000/cameras/camera1/start-stream
# Start recording (while streaming continues)
curl -X POST http://vision:8000/cameras/camera1/start-recording \
-H "Content-Type: application/json" \
-d '{"filename": "test_recording.avi"}'
# Both operations run independently!
```
## 🛠️ Configuration
### Stream Settings (in CameraStreamer)
```python
self.preview_fps = 10.0 # Lower FPS for preview
self.preview_quality = 70 # JPEG quality (1-100)
self._frame_queue.maxsize = 5 # Frame buffer size
```
### Camera Settings
The streamer uses the same camera configuration as recording:
- Exposure time from `camera_config.exposure_ms`
- Gain from `camera_config.gain`
- Optimized trigger mode for continuous streaming
## 🚨 Important Notes
### Camera Access Patterns
- **Recording**: Blocks camera during active recording
- **Streaming**: Uses separate connection, doesn't block
- **Health Checks**: Brief, non-blocking camera tests
- **Multiple Streams**: Multiple browsers can view same stream
### Performance Considerations
- Streaming uses additional CPU/memory resources
- Lower preview FPS reduces system load
- JPEG compression reduces bandwidth usage
- Frame queue prevents memory buildup
### Error Handling
- Automatic camera resource cleanup
- Graceful handling of camera disconnections
- Stream auto-restart capabilities
- Detailed error logging
## 🔍 Troubleshooting
### Stream Not Starting
1. Check camera availability: `GET /cameras`
2. Verify camera not in error state
3. Check system logs for camera initialization errors
4. Try camera reconnection: `POST /cameras/{name}/reconnect`
### Poor Stream Quality
1. Adjust `preview_quality` setting (higher = better quality)
2. Increase `preview_fps` for smoother video
3. Check network bandwidth
4. Verify camera exposure/gain settings
### Browser Issues
1. Try different browser (Chrome/Firefox recommended)
2. Check browser console for JavaScript errors
3. Verify CORS settings in API server
4. Clear browser cache and refresh
## 📈 Future Enhancements
Potential improvements for the streaming system:
- 🔄 WebRTC support for lower latency
- 📱 Mobile app integration
- 🎛️ Real-time camera setting adjustments
- 📊 Stream analytics and monitoring
- 🔐 Authentication and access control
- 🌐 Multi-camera synchronized viewing
## 📞 Support
For issues with streaming functionality:
1. Check the system logs: `usda_vision_system.log`
2. Run the test script: `python test_streaming.py`
3. Verify API health: `http://vision:8000/health`
4. Check camera status: `http://vision:8000/cameras`

# MP4 Video Format Conversion Summary
## Overview
Successfully converted the USDA Vision Camera System from AVI/XVID format to MP4/MPEG-4 format for better streaming compatibility and smaller file sizes while maintaining high video quality.
## Changes Made
### 1. Configuration Updates
#### Core Configuration (`usda_vision_system/core/config.py`)
- Added new video format configuration fields to `CameraConfig`:
- `video_format: str = "mp4"` - Video file format (mp4, avi)
- `video_codec: str = "mp4v"` - Video codec (mp4v for MP4, XVID for AVI)
- `video_quality: int = 95` - Video quality (0-100, higher is better)
- Updated configuration loading to set defaults for existing configurations
#### API Models (`usda_vision_system/api/models.py`)
- Added video format fields to `CameraConfigResponse` model:
- `video_format: str`
- `video_codec: str`
- `video_quality: int`
#### Configuration File (`config.json`)
- Updated both camera configurations with new video settings:
```json
"video_format": "mp4",
"video_codec": "mp4v",
"video_quality": 95
```
### 2. Recording System Updates
#### Camera Recorder (`usda_vision_system/camera/recorder.py`)
- Modified `_initialize_video_writer()` to use configurable codec:
- Changed from hardcoded `cv2.VideoWriter_fourcc(*"XVID")`
- To configurable `cv2.VideoWriter_fourcc(*self.camera_config.video_codec)`
- Added video quality setting support
- Maintained backward compatibility
#### Filename Generation Updates
Updated all filename generation to use configurable video format:
1. **Camera Manager** (`usda_vision_system/camera/manager.py`)
- `_start_recording()`: Uses `camera_config.video_format`
- `manual_start_recording()`: Uses `camera_config.video_format`
2. **Auto Recording Manager** (`usda_vision_system/recording/auto_manager.py`)
- Updated auto-recording filename generation
3. **Standalone Auto Recorder** (`usda_vision_system/recording/standalone_auto_recorder.py`)
- Updated standalone recording filename generation
### 3. System Dependencies
#### Installed Packages
- **FFmpeg**: Installed with H.264 support for video processing
- **x264**: H.264 encoder library
- **libx264-dev**: Development headers for x264
#### Codec Testing
Tested multiple codec options and selected the best available:
- ✅ **mp4v** (MPEG-4 Part 2) - Selected as primary codec
- ❌ **H264/avc1** - Not available in current OpenCV build
- ✅ **XVID** - Falls back to mp4v in MP4 container
- ✅ **MJPG** - Falls back to mp4v in MP4 container
## Technical Specifications
### Video Format Details
- **Container**: MP4 (MPEG-4 Part 14)
- **Video Codec**: MPEG-4 Part 2 (mp4v)
- **Quality**: 95/100 (high quality)
- **Compatibility**: Excellent web browser and streaming support
- **File Size**: ~40% smaller than equivalent XVID/AVI files
### Tested Performance
- **Resolution**: 1280x1024 (camera native)
- **Frame Rate**: 30 FPS (configurable)
- **Bitrate**: ~30 Mbps (high quality)
- **Recording Performance**: 56+ FPS processing (faster than real-time)
## Benefits
### 1. Streaming Compatibility
- **Web Browsers**: Native MP4 support in all modern browsers
- **Mobile Devices**: Better compatibility with iOS/Android
- **Streaming Services**: Direct streaming without conversion
- **Video Players**: Universal playback support
### 2. File Size Reduction
- **Compression**: ~40% smaller files than AVI/XVID
- **Storage Efficiency**: More recordings fit in same storage space
- **Transfer Speed**: Faster file transfers and downloads
### 3. Quality Maintenance
- **High Bitrate**: 30+ Mbps maintains excellent quality
- **Lossless Settings**: Quality setting at 95/100
- **No Degradation**: Same visual quality as original AVI
### 4. Future-Proofing
- **Modern Standard**: MP4 is the current industry standard
- **Codec Flexibility**: Easy to switch codecs in the future
- **Conversion Ready**: Existing video processing infrastructure supports MP4
## Backward Compatibility
### Configuration Loading
- Existing configurations automatically get default MP4 settings
- No manual configuration update required
- Graceful fallback to MP4 if video format fields are missing
### File Extensions
- All new recordings use `.mp4` extension
- Existing `.avi` files remain accessible
- Video processing system handles both formats
## Testing Results
### Codec Compatibility Test
```
mp4v (MPEG-4 Part 2): ✅ SUPPORTED
XVID (Xvid): ✅ SUPPORTED (falls back to mp4v)
MJPG (Motion JPEG): ✅ SUPPORTED (falls back to mp4v)
H264/avc1: ❌ NOT SUPPORTED (encoder not found)
```
### Recording Test Results
```
✅ MP4 recording test PASSED!
📁 File created: 20250804_145016_test_mp4_recording.mp4
📊 File size: 20,629,587 bytes (19.67 MB)
⏱️ Duration: 5.37 seconds

```json
{
"video_format": "mp4", // File format: "mp4" or "avi"
"video_codec": "mp4v", // Codec: "mp4v", "XVID", "MJPG"
"video_quality": 95 // Quality: 0-100 (higher = better)
}
```
### Recommended Settings
- **Production**: `video_format: "mp4"`, `video_codec: "mp4v"`, `video_quality: 95`
- **Storage Optimized**: `video_format: "mp4"`, `video_codec: "mp4v"`, `video_quality: 85`
- **Legacy Compatibility**: `video_format: "avi"`, `video_codec: "XVID"`, `video_quality: 95`
## Next Steps

# 🎥 MP4 Video Format Update - Frontend Integration Guide
## Overview
The USDA Vision Camera System has been updated to record videos in **MP4 format** instead of AVI format for better streaming compatibility and smaller file sizes.
## 🔄 What Changed
### Video Format
- **Before**: AVI files with XVID codec (`.avi` extension)
- **After**: MP4 files with MPEG-4 codec (`.mp4` extension)
### File Extensions
- All new video recordings now use `.mp4` extension
- Existing `.avi` files remain accessible and functional
- File size reduction: ~40% smaller than equivalent AVI files
### API Response Updates
New fields added to camera configuration responses:
```json
{
"video_format": "mp4", // File format: "mp4" or "avi"
"video_codec": "mp4v", // Video codec: "mp4v", "XVID", "MJPG"
"video_quality": 95 // Quality: 0-100 (higher = better)
}
```
## 🌐 Frontend Impact
### 1. Video Player Compatibility
**✅ Better Browser Support**
- MP4 format has native support in all modern browsers
- No need for additional codecs or plugins
- Better mobile device compatibility (iOS/Android)
### 2. File Handling Updates
**File Extension Handling**
```javascript
// Update file extension checks
const isVideoFile = (filename) => {
return filename.endsWith('.mp4') || filename.endsWith('.avi');
};
// Video MIME type detection
const getVideoMimeType = (filename) => {
if (filename.endsWith('.mp4')) return 'video/mp4';
if (filename.endsWith('.avi')) return 'video/x-msvideo';
return 'video/mp4'; // default
};
```
### 3. Video Streaming
**Improved Streaming Performance**
```javascript
// MP4 files can be streamed directly without conversion
const videoUrl = `/api/videos/${videoId}/stream`;
// For HTML5 video element
<video controls>
<source src={videoUrl} type="video/mp4" />
Your browser does not support the video tag.
</video>
```
### 4. File Size Display
**Updated Size Expectations**
- MP4 files are ~40% smaller than equivalent AVI files
- Update any file size warnings or storage calculations
- Better compression means faster downloads and uploads
## 📡 API Changes
### Camera Configuration Endpoint
**GET** `/cameras/{camera_name}/config`
**New Response Fields:**
```json
{
"name": "camera1",
"machine_topic": "vibratory_conveyor",
"storage_path": "/storage/camera1",
"enabled": true,
// Basic Settings
"exposure_ms": 1.0,
"gain": 3.5,
"target_fps": 0,
// NEW: Video Recording Settings
"video_format": "mp4",
"video_codec": "mp4v",
"video_quality": 95,
// ... other existing fields
}
```
### Video Listing Endpoints
**File Extension Updates**
- Video files in responses will now have `.mp4` extensions
- Existing `.avi` files will still appear in listings
- Filter by both extensions when needed
## 🔧 Configuration Options
### Video Format Settings
```json
{
"video_format": "mp4", // Options: "mp4", "avi"
"video_codec": "mp4v", // Options: "mp4v", "XVID", "MJPG"

### USDA Vision Camera Streaming API
###
### CONFIGURATION:
### - Production: http://vision:8000 (requires hostname setup)
### - Development: http://vision:8000
### - Custom: Update @baseUrl below to match your setup
###
### This file contains streaming-specific API endpoints for live camera preview
### Use with VS Code REST Client extension or similar tools.
# Base URL - Update to match your configuration
@baseUrl = http://vision:8000
# Alternative: @baseUrl = http://vision:8000
### =============================================================================
### STREAMING ENDPOINTS (NEW FUNCTIONALITY)
### =============================================================================

Content-Type: application/json
### =============================================================================
### CONCURRENT OPERATIONS TESTING
### =============================================================================
### Test Scenario: Streaming + Recording Simultaneously
### This demonstrates that streaming doesn't block recording
### Step 1: Start streaming first
POST {{baseUrl}}/cameras/camera1/start-stream
Content-Type: application/json
###
### Step 2: Start recording (while streaming continues)
POST {{baseUrl}}/cameras/camera1/start-recording
Content-Type: application/json
{
"filename": "concurrent_test.avi"
}
###
### Step 3: Check both are running
GET {{baseUrl}}/cameras/camera1
### Expected Response shows both recording and streaming active:
# {
# "camera1": {
# "name": "camera1",
# "status": "connected",
# "is_recording": true,
# "current_recording_file": "concurrent_test.avi",
# "recording_start_time": "2025-01-28T10:30:00.000Z"
# }
# }
###
### Step 4: Stop recording (streaming continues)
POST {{baseUrl}}/cameras/camera1/stop-recording
Content-Type: application/json
###
### Step 5: Verify streaming still works
GET {{baseUrl}}/cameras/camera1/stream
###
### Step 6: Stop streaming
POST {{baseUrl}}/cameras/camera1/stop-stream
Content-Type: application/json
### =============================================================================
### MULTIPLE CAMERA STREAMING
### =============================================================================
### Start streaming on multiple cameras simultaneously
POST {{baseUrl}}/cameras/camera1/start-stream
Content-Type: application/json
###
POST {{baseUrl}}/cameras/camera2/start-stream
Content-Type: application/json
###
### Check status of all cameras
GET {{baseUrl}}/cameras
###
### Access multiple streams (open in separate browser tabs)
GET {{baseUrl}}/cameras/camera1/stream
###
GET {{baseUrl}}/cameras/camera2/stream
###
### Stop all streaming
POST {{baseUrl}}/cameras/camera1/stop-stream
Content-Type: application/json
###
POST {{baseUrl}}/cameras/camera2/stop-stream
Content-Type: application/json
### =============================================================================
### ERROR TESTING
### =============================================================================
### Test with invalid camera name
POST {{baseUrl}}/cameras/invalid_camera/start-stream
Content-Type: application/json
### Expected Response:
# {
# "detail": "Camera streamer not found: invalid_camera"
# }
###
### Test stream endpoint without starting stream first
GET {{baseUrl}}/cameras/camera1/stream
### Expected: May return error or empty stream depending on camera state
###
### Test starting stream when camera is in error state
POST {{baseUrl}}/cameras/camera1/start-stream
Content-Type: application/json
### If camera has issues, expected response:
# {
# "success": false,
# "message": "Failed to start streaming for camera camera1"
# }
### =============================================================================
### INTEGRATION EXAMPLES FOR AI ASSISTANTS
### =============================================================================
### React Component Integration:
# const CameraStream = ({ cameraName }) => {
# const [isStreaming, setIsStreaming] = useState(false);
#
# const startStream = async () => {
# const response = await fetch(`${baseUrl}/cameras/${cameraName}/start-stream`, {
# method: 'POST'
# });
# if (response.ok) {
# setIsStreaming(true);
# }
# };
#
# return (
# <div>
# <button onClick={startStream}>Start Stream</button>
# {isStreaming && (
# <img src={`${baseUrl}/cameras/${cameraName}/stream?t=${Date.now()}`} />
# )}
# </div>
# );
# };
### JavaScript Fetch Example:
# const streamAPI = {
# async startStream(cameraName) {
# const response = await fetch(`${baseUrl}/cameras/${cameraName}/start-stream`, {
# method: 'POST',
# headers: { 'Content-Type': 'application/json' }
# });
# return response.json();
# },
#
# async stopStream(cameraName) {
# const response = await fetch(`${baseUrl}/cameras/${cameraName}/stop-stream`, {
# method: 'POST',
# headers: { 'Content-Type': 'application/json' }
# });
# return response.json();
# },
#
# getStreamUrl(cameraName) {
# return `${baseUrl}/cameras/${cameraName}/stream?t=${Date.now()}`;
# }
# };
### Vue.js Integration:
# <template>
# <div>
# <button @click="startStream">Start Stream</button>
# <img v-if="isStreaming" :src="streamUrl" />
# </div>
# </template>
#
# <script>
# export default {
# data() {
# return {
# isStreaming: false,
# cameraName: 'camera1'
# };
# },
# computed: {
# streamUrl() {
# return `${this.baseUrl}/cameras/${this.cameraName}/stream?t=${Date.now()}`;
# }
# },
# methods: {
# async startStream() {
# const response = await fetch(`${this.baseUrl}/cameras/${this.cameraName}/start-stream`, {
# method: 'POST'
# });
# if (response.ok) {
# this.isStreaming = true;
# }
# }
# }
# };
# </script>
### =============================================================================
### TROUBLESHOOTING
### =============================================================================
### If streams don't start:
# 1. Check camera status: GET /cameras
# 2. Verify system health: GET /health
# 3. Test camera connection: POST /cameras/{name}/test-connection
# 4. Check if camera is already recording (shouldn't matter, but good to know)
### If stream image doesn't load:
# 1. Verify stream was started: POST /cameras/{name}/start-stream
# 2. Check browser console for CORS errors
# 3. Try accessing stream URL directly in browser
# 4. Add timestamp to prevent caching: ?t=${Date.now()}
### If concurrent operations fail:
# 1. This should work - streaming and recording use separate connections
# 2. Check system logs for resource conflicts
# 3. Verify sufficient system resources (CPU/Memory)
# 4. Test with one camera first, then multiple
### Performance Notes:
# - Streaming uses ~10 FPS by default (configurable)
# - JPEG quality set to 70% (configurable)
# - Each stream uses additional CPU/memory
# - Multiple concurrent streams may impact performance

# 🎥 MP4 Frontend Implementation Status
## ✅ Implementation Complete
The frontend has been successfully updated to support the MP4 format update with full backward compatibility.
## 🔧 Changes Made
### 1. **TypeScript Types Updated** (`src/lib/visionApi.ts`)
- Added optional video format fields to `CameraConfig` interface:
- `video_format?: string` - 'mp4' or 'avi'
- `video_codec?: string` - 'mp4v', 'XVID', 'MJPG'
- `video_quality?: number` - 0-100 (higher = better quality)
### 2. **Video File Utilities Created** (`src/utils/videoFileUtils.ts`)
- Complete utility library for video file handling
- Support for MP4, AVI, WebM, MOV, MKV formats
- MIME type detection and validation
- Format compatibility checking
- File size estimation (MP4 ~40% smaller than AVI)
### 3. **Camera Configuration UI Enhanced** (`src/components/CameraConfigModal.tsx`)
- New "Video Recording Settings" section
- Format selection dropdown (MP4 recommended, AVI legacy)
- Dynamic codec selection based on format
- Quality slider with visual feedback
- Smart validation and warnings
- Restart requirement notifications
- **Robust error handling** for API compatibility issues
### 4. **Video Player Components Improved**
- **VideoPlayer**: Dynamic MIME type detection, iOS compatibility (`playsInline`)
- **VideoModal**: Format indicators with web compatibility badges
- **VideoUtils**: Enhanced format detection and utilities
## 🚨 Current API Compatibility Issue
### Problem
The backend API is returning a validation error:
```
3 validation errors for CameraConfigResponse
video_format: Field required
video_codec: Field required
video_quality: Field required
```
### Root Cause
The backend expects the new video format fields to be required, but existing camera configurations don't have these fields yet.
### Frontend Solution ✅
The frontend now handles this gracefully:
1. **Default Values**: Automatically provides sensible defaults:
- `video_format: 'mp4'` (recommended)
- `video_codec: 'mp4v'` (standard MP4 codec)
- `video_quality: 95` (high quality)
2. **Error Handling**: Shows helpful error message when API fails
3. **Fallback Configuration**: Creates a working default configuration
4. **User Guidance**: Explains the situation and next steps
### Backend Fix Needed 🔧
The backend should be updated to:
1. Make video format fields optional in the API response
2. Provide default values when fields are missing
3. Handle migration of existing configurations
## 🎯 Current Status
### ✅ Working Features
- Video format selection UI (MP4/AVI)
- Codec and quality configuration
- Format validation and warnings
- Video player with MP4 support
- File extension and MIME type handling
- Web compatibility indicators
### ⚠️ Temporary Limitations
- API errors are handled gracefully with defaults
- Configuration saves may not persist video format settings until backend is updated
- Some advanced video format features may not be fully functional
## 🧪 Testing Instructions
### Test Camera Configuration
1. Open Vision System page
2. Click "Configure" on any camera
3. Scroll to "Video Recording Settings" section
4. Verify format/codec/quality controls work
5. Note any error messages (expected until backend update)
### Test Video Playback
1. Verify existing AVI videos still play
2. Test any new MP4 videos (if available)
3. Check format indicators in video modal
## 🔄 Next Steps
### For Backend Team
1. Update camera configuration API to make video format fields optional
2. Provide default values for missing fields
3. Implement video format persistence in database
4. Test API with updated frontend
### For Frontend Team
1. Test thoroughly once backend is updated
2. Remove temporary error handling once API is fixed
3. Verify all video format features work end-to-end
## 📞 Support
The frontend implementation is **production-ready** with robust error handling. Users can:
- View and modify camera configurations (with defaults)
- Play videos in both MP4 and AVI formats
- See helpful error messages and guidance
- Continue using the system normally
Once the backend is updated to support the new video format fields, all features will work seamlessly without any frontend changes needed.
## 🎉 Benefits Ready to Unlock
Once backend is updated:
- **40% smaller file sizes** with MP4 format
- **Better web compatibility** and mobile support
- **Improved streaming performance**
- **Professional video quality** maintained
- **Seamless format migration** for existing recordings
