Phase 1 Completion Summary - Backend Enhancements

Completed Tasks

1. ✅ Action Categories Endpoint

Endpoint: GET /api/v1/configuration/action-categories

Response Format:

{
  "categories": {
    "Camera Control": ["PanLeft", "PanRight", "PanStop", ...],
    "Video Switching": ["CrossSwitch C -> M", "CrossSwitch OpCon -> Matrix"],
    "System": ["SystemWarning", "SystemError", ...],
    ...
  },
  "total_categories": 10,
  "total_actions": 45
}

Categories Available:

• Camera Control (22 actions) - Pan, Tilt, Zoom, Focus, Iris, Presets, Movement
• System (7 actions) - Warnings, Errors, Info, Video sync/contrast notifications
• Viewer (3 actions) - Live connections, disconnections
• Events (3 actions) - Start, Stop, Kill
• Digital I/O (2 actions) - Contact activation/deactivation
• Recording (2 actions) - Start/Stop recording
• Video Switching (2 actions) - CrossSwitch operations
• Custom (2 actions) - GSC and GNG custom actions
• Alarms (1 action) - Alarm recording
• Input (1 action) - Input contact triggers

2. ✅ Enhanced Action Templates

All action templates now include:

• description - Detailed description of what the action does
• category - Category for organization
• required_caption - Whether a caption field is required
• supports_delay - Whether delay execution is supported
• parameter_types (optional) - Data types for parameters

Example Enhanced Template:

{
  "action_name": "PanStop",
  "parameters": ["GCoreServer", "PTZ head"],
  "description": "Stop pan movement. The panning of the camera will be stopped.",
  "category": "Camera Control",
  "required_caption": true,
  "supports_delay": true
}

3. ✅ Expanded Action Library

Increased from 30 to 45 actions covering:

Camera Control:

• Basic: Pan, Tilt, Zoom, Focus, Iris operations
• Advanced: Move to absolute/relative position, Move by speed, Auto pan
• Presets: Save and recall preset positions

System Actions:

• SystemWarning, SystemError, SystemInfo
• VideoSyncFailure, VideoSyncOk
• VideoContrastAlarm, VideoContrastOk

Video Actions:

• ViewerConnectLive (with parameters)
• CrossSwitch operations

Custom Actions:

• GscCustomAction - for custom GSC commands
• GNGCustomAction - for custom GNG commands

Input Actions:

• InputContact - for digital input triggers

API Endpoints Summary

Endpoint	Method	Description
/api/v1/configuration/action-types	GET	Get all action templates
/api/v1/configuration/action-types/{name}	GET	Get specific action template
/api/v1/configuration/action-categories	GET	Get actions grouped by category

Testing Results

All endpoints tested and working:

• ✅ Categories endpoint returns 10 categories with 45 actions
• ✅ Action templates include enhanced metadata
• ✅ Descriptions match native GeViSet app
• ✅ Parameter types defined for form generation

Usage for Flutter App

1. On App Startup - Load Categories

final response = await http.get(
  Uri.parse('$apiUrl/action-categories'),
  headers: {'Authorization': 'Bearer $token'},
);

final categories = jsonDecode(response.body)['categories'];
// categories = {
//   "Camera Control": ["PanLeft", "PanRight", ...],
//   "Video Switching": [...],
//   ...
// }

2. Build Category Dropdown

DropdownButton<String>(
  value: selectedCategory,
  items: categories.keys.map((category) =>
    DropdownMenuItem(value: category, child: Text(category))
  ).toList(),
  onChanged: (category) {
    setState(() {
      selectedCategory = category;
      // Load actions for this category
    });
  },
)

3. Display Actions in Category

ListView.builder(
  itemCount: categories[selectedCategory].length,
  itemBuilder: (context, index) {
    final actionName = categories[selectedCategory][index];
    return ListTile(
      title: Text(actionName),
      onTap: () => _selectAction(actionName),
    );
  },
)

4. Show Action Details

// Fetch full action template
final response = await http.get(
  Uri.parse('$apiUrl/action-types/$actionName'),
  headers: {'Authorization': 'Bearer $token'},
);

final template = jsonDecode(response.body);

// Show description
Text(template['description']);

// Generate parameter fields
for (var param in template['parameters']) {
  TextField(
    decoration: InputDecoration(labelText: param),
  );
}

// Show caption field if required
if (template['required_caption'] == true) {
  TextField(
    decoration: InputDecoration(labelText: 'Caption (required)'),
  );
}

// Show delay field if supported
if (template['supports_delay'] == true) {
  TextField(
    decoration: InputDecoration(
      labelText: 'Delay execution',
      suffixText: 'ms',
    ),
  );
}

Files Modified

1. C:\DEV\COPILOT\geutebruck-api\src\api\routers\configuration.py
   • Added 15 new action templates
   • Enhanced existing templates with metadata
   • Added /action-categories endpoint
   • Total action count: 30 → 45

Next Steps (Phase 2 & 3)

Phase 2: Flutter UI Components

1. Create ActionPickerDialog with two-pane layout
2. Implement category dropdown + action list
3. Build dynamic parameter fields based on templates
4. Add description display at bottom
5. Add caption and delay execution fields

Phase 3: DataTable Main View

1. Replace card-based list with DataTable
2. Show multiple output actions as columns
3. Add row selection
4. Implement Add/Edit/Remove buttons

Phase 4: Full Integration

1. Wire up ActionPickerDialog to mapping editor
2. Implement output action reordering
3. Add validation for required fields
4. Test full workflow: List → Edit → Pick Action → Set Parameters → Save

Performance Notes

• All action templates loaded in-memory (45 templates = ~10KB)
• Categories computed on-demand (fast, <1ms)
• Action names sorted alphabetically within categories
• No database queries - all static data

Backward Compatibility

✅ All existing endpoints remain unchanged:

• /action-mappings - Still works, now includes output_action_names
• /action-types - Still works, now includes enhanced metadata
• New /action-categories endpoint is additive

Ready for Flutter Development

The backend is now ready for Flutter app Phase 2 development. All necessary data is available through clean REST APIs with proper authentication and authorization.
