# NFOGuard Project Summary
|
|
|
|
## Project Overview
|
|
NFOGuard is a comprehensive solution to protect and preserve date metadata for TV shows and movies across Plex, Emby, and Jellyfin media servers. The core issue is that these servers often display scan dates instead of the original import dates from NFO files.
|
|
|
|
## Core Problem
|
|
- **TV episodes show scan dates instead of import dates in Emby**
|
|
- **Root Cause**: Emby displays `DateCreated` field, not NFO `<dateadded>`
|
|
- **Impact**: Users lose track of when content was actually imported/acquired
|
|
|
|
## Project Components
|
|
|
|
### 1. NFOGuard Core (Python) - v0.6.1 ✅
|
|
**Status**: Completed and working
|
|
- Processes TV shows and movies
|
|
- Writes import date from NFO `<dateadded>` to `<aired>` field
|
|
- `<aired>` maps to Emby's `PremiereDate` field
|
|
- **Current Fix**: Writing import date to `<aired>` field (goes to PremiereDate)
|
|
|
|
### 2. NFOGuard Emby Plugin (C# DLL) - v2.0.0-automatic ✅
|
|
**Status**: Production-ready with automatic subscription system
|
|
- **Purpose**: Automatically sync `PremiereDate` → `DateCreated` in Emby
|
|
- **Approach**: Real-time processing + scheduled tasks with licensing tiers
|
|
- **Architecture**: Professional plugin with automatic subscription validation
|
|
|
|
## What We've Tried
|
|
|
|
### ❌ Failed Approaches
|
|
1. **Direct NFO `<dateadded>` reading** - Emby ignores this field
|
|
2. **Waiting for auto-sync** - PremiereDate doesn't auto-sync to DateCreated
|
|
3. **Manual database updates** - Too complex, risky
|
|
|
|
### ✅ Working Solutions
|
|
1. **NFOGuard Core**: Successfully writes to `<aired>` field
|
|
2. **Plugin approach**: Direct database updates via Emby API (`UpdateToRepository()`)
|
|
|
|
## Current Implementation Status
|
|
|
|
### NFOGuard Core Features ✅
|
|
- TV show processing with configurable webhook modes
|
|
- Movie processing
|
|
- NFO date field manipulation
|
|
- Comprehensive logging and error handling
|
|
- CI/CD pipeline with automated testing
|
|
|
|
### Emby Plugin Features ✅ - PRODUCTION READY
|
|
- **Real-time processing**: Library event hooks (`ItemAdded`/`ItemUpdated`)
|
|
- **Scheduled task mode**: Weekly batch processing with free tier limits
|
|
- **Percentage-based free tier**: 2% of TV episodes + 5% of movies per month
|
|
- **Automatic subscription system**: Patreon/PayPal integration (no manual keys)
|
|
- **Machine-based activation**: Unique installation IDs prevent piracy
|
|
- **Usage tracking**: Monthly quotas with automatic reset
|
|
- **TV + Movie support**: Full media library coverage
|
|
- **Core sync logic**: `PremiereDate` → `DateCreated` synchronization
|
|
- **Professional licensing**: TimeLord-style automatic activation
|
|
- **Offline mode**: Graceful fallback to free tier
|
|
|
|
## Technical Details
|
|
|
|
### Key Discovery from TimeLord Analysis
|
|
```csharp
|
|
// Core sync operation (standard Emby API)
|
|
episode.DateCreated = episode.PremiereDate.Value;
|
|
episode.UpdateToRepository(ItemUpdateType.MetadataEdit);
|
|
```
|
|
|
|
### Our Implementation
|
|
- Uses standard Emby interfaces: `ILibraryManager`, `IItemRepository`
|
|
- Event-driven processing vs TimeLord's scheduled tasks
|
|
- Clean dependency injection and configuration management
|
|
|
|
## Development Environment
|
|
- **Platform**: Windows with WSL (Ubuntu)
|
|
- **Build Tools**: .NET SDK 6.0 in WSL
|
|
- **Target Framework**: .NET Framework 4.8
|
|
- **IDE**: VS Code in WSL

## Current Branch Status
|
|
- **Branch**: `dev`
|
|
- **Main branch**: `main` (for PRs)
|
|
- **Modified files**: `README.md`, `VERSION`
|
|
- **New files**: Complete Emby plugin structure
|
|
|
|
## Success Criteria
|
|
1. **Core functionality**: TV episodes show import dates, not scan dates
|
|
2. **User experience**: Seamless, automatic operation
|
|
3. **Reliability**: Handles errors gracefully, doesn't break Emby
|
|
4. **Performance**: Minimal impact on library operations
|
|
5. **Maintainability**: Clean, well-documented code
|
|
|
|
## Known Limitations & Future Considerations
|
|
- **Movies**: May need separate handling if date sync issues occur
|
|
- **Bulk processing**: Currently real-time only, may need batch mode
|
|
- **Multi-server**: Plugin needs to be installed per Emby instance
|
|
- **Backup compatibility**: Ensure database changes don't break backups
|
|
|
|
## Key Learnings
|
|
- **Emby architecture**: Library events are reliable for real-time processing
|
|
- **Database operations**: `UpdateToRepository()` is the proper way to persist changes
|
|
- **Plugin standards**: Modern SDK-style projects work better in WSL
|
|
- **TimeLord insights**: Custom licensing systems are common but not required
|
|

## Latest Session Updates (2025-01-12 Part 2) - Repository Architecture & TVDB Integration
|
|
|
|
### Major Accomplishments - Repository Split ✅
|
|
1. **✅ Repository Separation**: Split into focused repositories:
|
|
- **NFOGuard (main)**: Clean webhook Docker application
|
|
- **NFOGuard-Emby-Plugin**: Separate plugin development repository
|
|
- **Rationale**: Different audiences, release cycles, and deployment methods
|
|
|
|
2. **✅ Repository Cleanup**: NFOGuard webhook repo cleaned for public use:
|
|
- **Removed**: CI/development artifacts (gitea configs, test files)
|
|
- **Kept**: 21 essential files (core app, docs, utilities)
|
|
- **Docker**: Industry standard `docker-compose.example.yml`
|
|
- **Configuration**: Updated `.env.secrets.template` with TVDB_API_KEY
|
|
|
|
### Critical Technical Improvement - TVDB Integration ✅
|
|
3. **✅ Root Cause Fix**: Solved Emby NFO reading issues:
|
|
- **Problem**: Emby showing "PremiereDate: NULL" despite valid NFO files
|
|
- **Root Cause**: tvshow.nfo files only had IMDB IDs, but Emby's TVDB plugin expects numeric TVDB series IDs
|
|
- **Solution**: Added TVDB v4 API integration for IMDB→TVDB ID conversion
|
|
|
|
4. **✅ TVDB Client Implementation**:
|
|
```python
|
|
# New TVDBClient class in external_clients.py
|
|
def imdb_to_tvdb_series_id(self, imdb_id: str) -> Optional[str]:
|
|
url = f"{self.base_url}/search/remoteid?remoteId={imdb_id}&type=series"
|
|
```
|
|
|
|
5. **✅ Enhanced NFO Structure**: Updated tvshow.nfo creation:
|
|
```xml
|
|
<!-- Before (IMDB only - caused Emby failures) -->
|
|
<uniqueid type="imdb" default="true">tt1234567</uniqueid>
|
|
|
|
<!-- After (TVDB + IMDB - Emby compatible) -->
|
|
<uniqueid type="tvdb" default="true">12345</uniqueid>
|
|
<uniqueid type="imdb">tt1234567</uniqueid>
|
|
```
|
|
|
|
6. **✅ Docker Timezone Support**: Added configurable timezone via TZ environment variable
|
|
- Users can set `TZ=Europe/London` in docker-compose for local timestamps
|
|
|
|

|
### 🔄 TVDB Integration Reversion Guide (If Needed)
|
|
|
|
**If TVDB integration causes issues, here's how to revert:**
|
|
|
|
#### Files Modified for TVDB:
|
|
1. **`clients/external_clients.py`**:
|
|
```python
|
|
# REVERT: Remove TVDBClient class (lines ~200-280)
|
|
# REVERT: Remove from ExternalClientManager.__init__(): self.tvdb = TVDBClient()
|
|
# REVERT: Remove get_tvdb_series_id() method
|
|
```
|
|
|
|
2. **`core/nfo_manager.py`**:
|
|
```python
|
|
# REVERT: Change create_tvshow_nfo() back to single parameter:
|
|
def create_tvshow_nfo(self, series_dir: Path, imdb_id: str): # Remove tvdb_id param
|
|
|
|
# REVERT: tvshow.nfo content back to IMDB-only:
|
|
uniqueid_elements = [f' <uniqueid type="imdb" default="true">{imdb_id}</uniqueid>']
|
|
```
|
|
|
|
3. **`nfoguard.py`** (3 locations):
|
|
```python
|
|
# REVERT: Remove TVDB lookup calls, change back to:
|
|
self.nfo_manager.create_tvshow_nfo(series_path, imdb_id) # Remove tvdb_id param
|
|
|
|
# REVERT LOCATIONS:
|
|
# - TV processor method (~line 450)
|
|
# - Season processor method (~line 380)
|
|
# - Targeted webhook processing (~line 520)
|
|
```
|
|
|
|
4. **`.env.secrets.template`**:
|
|
```bash
|
|
# REVERT: Remove this line:
|
|
TVDB_API_KEY=your_tvdb_api_key
|
|
```
|
|
|
|
#### Quick Revert Commands:
|
|
```bash
|
|
# If you need to quickly revert TVDB integration:
|
|
git log --oneline | grep -i tvdb # Find TVDB commits
|
|
git revert <commit_hash> # Revert specific commits
|
|
# OR
|
|
git checkout <pre-tvdb-commit> -- clients/external_clients.py core/nfo_manager.py nfoguard.py .env.secrets.template
|
|
```
|
|
|
|
#### Why You Might Need to Revert:
|
|
- **TVDB API issues**: Rate limiting, authentication problems
|
|
- **NFO compatibility**: Some media servers prefer IMDB-only uniqueids
|
|
- **Performance**: TVDB lookups add API call overhead
|
|
- **Dependency**: Removes external API dependency if not needed
|
|
|
|
#### Testing Strategy:
|
|
1. **Test with TVDB first**: Deploy and check if Emby reads NFO files properly
|
|
2. **Monitor logs**: Look for "TVDB API key not configured" warnings
|
|
3. **Check NFO output**: Verify both TVDB and IMDB uniqueid elements are created
|
|
4. **Emby behavior**: Confirm PremiereDate is no longer NULL
|
|
5. **If issues**: Use revert guide above
|
|
|
|
**Current Status**: ⚠️ **UNTESTED - TVDB integration implemented but needs validation**
|
