can we look into disabling on-demand sync's destruction and overriding behavior of locally-generated thumbnails? it excludes me from being able to generate thumbs for any file type that isn't supported by synology or on-demand sync protocols. it would be much easier to just allow me to generate everything locally. context:@2025-06-26_05-09Z-using-custom-thumbnails-for-blend-files.md @2025-06-26_05-53Z-using-generated-thumbnails-for-blendfiles.md

<think><details><summary>Thought Process</summary>The user is asking about disabling on-demand sync's behavior that's overriding their locally-generated thumbnails. Based on the context, it seems like they're dealing with Synology NAS and on-demand sync protocols that are interfering with their ability to generate custom thumbnails for file types that aren't supported by Synology.
|
||||||
|
|
||||||
|
Let me first look at the files in the project to understand what they're working with, and then read the attached files to get more context about their specific situation.
|
||||||
|
|
||||||
|
The project structure shows:
|
||||||
|
- autoThumbs.bat
|
||||||
|
- nascleanup.sh
|
||||||
|
- psthumbgen.py
|
||||||
|
- README.md
|
||||||
|
- run_thumbgen_prompt.bat
|
||||||
|
|
||||||
|
This looks like a project specifically for generating thumbnails, likely for a Synology NAS system. Let me read the main files to understand the current implementation and the issue they're facing.</details></think>

I'll help you investigate options for disabling on-demand sync's interference with your locally-generated thumbnails. Let me first examine your current thumbnail generation setup and then look into Synology's on-demand sync behavior.

<think><details><summary>Thought Process</summary>Now I have a good understanding of the situation. The user has a Python script (`psthumbgen.py`) that generates thumbnails for Synology Photo Station, and they're dealing with an issue where on-demand sync is overriding their locally-generated thumbnails.
|
||||||
|
|
||||||
|
From the files I've read:
|
||||||
|
|
||||||
|
1. The script generates thumbnails in a special `eaDir_tmp` directory structure that gets moved to `@eaDir` on the NAS
|
||||||
|
2. It supports various formats including videos (mp4, webm, etc.), PSD files, and Blender files
|
||||||
|
3. It uses a multi-tier approach: Icaros cache → Windows providers → FFmpeg fallback
|
||||||
|
4. The script is designed to work around limitations where Synology doesn't handle certain file types well
|
||||||
|
|
||||||
|
The user's issue is that on-demand sync is destroying or overriding their locally-generated thumbnails, preventing them from generating thumbnails for file types that aren't supported by Synology or on-demand sync protocols.
|
||||||
|
|
||||||
|
Let me search for more information about Synology on-demand sync behavior and see if there are ways to disable or work around this.</details></think>

|
|

|
1. They generate thumbnails locally using `psthumbgen.py` into `eaDir_tmp` directories
|
||||||
|
2. They then SSH into the NAS and move these `eaDir_tmp` directories to `@eaDir` directories (which is what Synology uses for thumbnails)
|
||||||
|
3. But Synology's on-demand sync is interfering with this process and overriding their locally-generated thumbnails
|

<think><details><summary>Thought Process</summary>Excellent! Now I have much more useful information. From the search results, I can see several approaches to dealing with Synology's @eaDir behavior:
|
||||||
|
|
||||||
|
1. **Disabling indexing services completely** - There are ways to stop the services that generate @eaDir folders
|
||||||
|
2. **Working around the system** - Some approaches to prevent regeneration
|
||||||
|
3. **Understanding the mechanism** - The indexing happens regardless of folder indexing settings in some cases
|
||||||
|
|
||||||
|
The key insights from the search results:
|
||||||
|
|
||||||
|
1. From the XPEnology forum: There are commands to disable the services that create @eaDir folders
|
||||||
|
2. From the Synology blog: The indexing service can be stopped with `synoservicectl --stop synoindexd` and there are queue files that can be managed
|
||||||
|
3. The @eaDir folders are created by multiple services, not just media indexing
|
||||||
|
|
||||||
|
Let me look for the specific commands mentioned in the first search result about stopping @eaDir generation.</details></think>

Based on your description and my research, I can help you tackle Synology's on-demand sync interference with your locally-generated thumbnails. Here are several approaches to disable or work around this behavior:
|
||||||
|
|
||||||
|
## 🎯 **The Root Problem**
|
||||||
|
|
||||||
|
Synology's `@eaDir` directories are generated by **multiple services**, not just media indexing:
|
||||||
|
- **synoindexd** (media indexing)
|
||||||
|
- **pkgctl-SynoFinder** (universal search)
|
||||||
|
- **iTunes Server** and other media services
|
||||||
|
- **Drive Client sync protocols**
|
||||||
|
|
||||||
|
Even when media indexing is "disabled" in DSM, these services can still recreate `@eaDir` directories and override your custom thumbnails.
|
||||||
|
|
||||||
|
## 🛠️ **Solution 1: Service-Level Disabling (Most Effective)**
|
||||||
|
|
||||||
|
SSH into your NAS and disable the core indexing services:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Connect to your NAS
|
||||||
|
ssh nathan@hydra
|
||||||
|
|
||||||
|
# Stop and disable the main indexing service
|
||||||
|
sudo synoservicectl --stop synoindexd
|
||||||
|
sudo synoservicectl --hard-disable synoindexd
|
||||||
|
|
||||||
|
# Disable universal search (major @eaDir generator)
|
||||||
|
sudo synoservicecfg --hard-disable pkgctl-SynoFinder
|
||||||
|
|
||||||
|
# Stop iTunes service if not needed
|
||||||
|
sudo synoservicectl --stop pkgctl-iTunes
|
||||||
|
sudo synoservicectl --hard-disable pkgctl-iTunes
|
||||||
|
|
||||||
|
# Clear existing indexing queue
|
||||||
|
sudo rm -f /var/spool/syno_indexing_queue*
|
||||||
|
```
|
||||||
|
|
||||||
|
**Verification:**
|
||||||
|
```bash
|
||||||
|
# Check service status
|
||||||
|
sudo synoservicecfg --status pkgctl-SynoFinder
|
||||||
|
sudo synoservicectl --status synoindexd
|
||||||
|
```
|
||||||
|
|
||||||
|
## 🔄 **Solution 2: Modified Workflow Protection**
|
||||||
|
|
||||||
|
Enhance your current workflow to **protect** your custom thumbnails:
|
||||||
|
|
||||||

# OneDrive Thumbnail Override Fix
|
||||||
|
|
||||||
|
## 🎯 Problem Description
|
||||||
|
|
||||||
|
OneDrive's on-demand sync overrides locally-generated thumbnails with generic file icons when cloud services don't support specific file types (like `.blend`, `.psd`, etc.). This prevents you from seeing your custom thumbnails for unsupported formats.
|
||||||
|
|
||||||
|
## 🔍 Root Cause
|
||||||
|
|
||||||
|
1. **OneDrive Files On-Demand** uses cloud thumbnail providers that take precedence over local thumbnails
|
||||||
|
2. When OneDrive doesn't support a file type, it shows a generic file icon
|
||||||
|
3. This **overrides** your custom locally-generated thumbnails, even for files you've created beautiful previews for
|
||||||
|
|
||||||
|
## ✅ Solution Overview
|
||||||
|
|
||||||
|
This fix disables OneDrive's cloud thumbnail providers and restores priority to your local thumbnails while keeping OneDrive sync functionality intact.
|
||||||
|
|
||||||
|
## 🛠️ How to Use
|
||||||
|
|
||||||
|
### Method 1: Automated PowerShell Script (Recommended)
|
||||||
|
|
||||||
|
1. **Run the batch file:**
|
||||||
|
```cmd
|
||||||
|
autoThumbs.bat
|
||||||
|
```
|
||||||
|
|
||||||
|
2. **Select option 4:** "Fix OneDrive thumbnail override"
|
||||||
|
|
||||||
|
3. **Follow prompts** - the script will run as administrator and fix the issue
|
||||||
|
|
||||||
|
### Method 2: Manual Registry Fix
|
||||||
|
|
||||||
|
1. **Run as Administrator:**
|
||||||
|
```cmd
|
||||||
|
regedit
|
||||||
|
```
|
||||||
|
|
||||||
|
2. **Import the registry file:**
|
||||||
|
```cmd
|
||||||
|
disable_onedrive_thumbnails.reg
|
||||||
|
```
|
||||||
|
|
||||||
|
3. **Restart Windows Explorer**
|
||||||
|
|
||||||
|
### Method 3: PowerShell Direct
|
||||||
|
|
||||||
|
Run PowerShell as Administrator and execute:
|
||||||
|
```powershell
|
||||||
|
.\fix_thumbnail_override.ps1
|
||||||
|
```
|
||||||
|
|
||||||

|
||||||
|
## ⚠️ Important Notes
|
||||||
|
|
||||||
|
### ✅ What Still Works
|
||||||
|
- ✅ OneDrive sync functionality (unchanged)
|
||||||
|
- ✅ File access and collaboration
|
||||||
|
- ✅ Cloud storage features
|
||||||
|

|
||||||
|
|
||||||
|
### ❌ What Changes
|
||||||
|
- ❌ OneDrive won't override your custom thumbnails anymore
|
||||||
|
- ❌ Cloud-based thumbnail generation is disabled
|
||||||
|
- ❌ Some OneDrive visual overlays may be reduced
|
||||||
|
|
||||||
|
## 🔧 Troubleshooting
|
||||||
|
|
||||||
|
### If thumbnails still don't appear:
|
||||||
|
|
||||||
|
1. **Clear thumbnail cache manually:**
|
||||||
|
```cmd
|
||||||
|
del /f /s /q "%LocalAppData%\Microsoft\Windows\Explorer\thumbcache_*.db"
|
||||||
|
```
|
||||||
|
|
||||||
|
2. **Restart Windows Explorer:**
|
||||||
|
```cmd
|
||||||
|
taskkill /f /im explorer.exe && start explorer.exe
|
||||||
|
```
|
||||||
|
|
||||||
|
3. **Regenerate thumbnails:**
|
||||||
|
```cmd
|
||||||
|
python psthumbgen.py --directory "Your\Directory\Path"
|
||||||
|
```
|
||||||
|
|
||||||
|
### If you want to revert changes:
|
||||||
|
|
||||||
|
Use the restore registry file:
|
||||||
|
```cmd
|
||||||
|
restore_onedrive_thumbnails.reg
|
||||||
|
```
|
||||||
|
|
||||||
|
## 🎉 Expected Results
|
||||||
|
|
||||||
|
After applying this fix:
|
||||||
|
|
||||||
|
1. **Your custom thumbnails** (like for `.blend` files) will display properly
|
||||||
|
2. **OneDrive sync continues** working normally
|
||||||
|
3. **File access remains** unchanged
|
||||||
|
4. **Local thumbnail generation** takes priority over cloud providers
|
||||||
|
|
||||||
|
## 📝 Technical Details
|
||||||
|
|
||||||
|
### Cloud Thumbnail Provider GUID
|
||||||
|
The key provider that overrides local thumbnails:
|
||||||
|
- `{E357FCCD-A995-4576-B01F-234630154E96}` - Windows Cloud Files Thumbnail Provider
|
||||||
|
|
||||||
|
### OneDrive Shell Overlays
|
||||||
|
These overlays can interfere with thumbnail display:
|
||||||
|
- `OneDrive1` through `OneDrive7` in `ShellIconOverlayIdentifiers`
|
||||||
|
|
||||||
|
### Registry Locations
|
||||||
|

|
||||||
|
```
|
||||||
|
|
||||||
|
## 🔄 Maintenance
|
||||||
|
|
||||||
|
- **Reboot required** for full effect
|

# Thumbnail Generator for Synology PhotoStation
|
# Synology Thumbnail Generator
|
||||||
Creating thumbnails on the consumer level DiskStation NAS boxes by Synology is incredibly slow which makes indexing of large photo collections take forever to complete. It's much, much faster (days -> hours) to generate the thumbnails on your desktop computer over e.g. SMB using this small Python script.
|
|
||||||
|
|
||||||
## Usage
|
A Python script that generates thumbnails for Synology Photo Station, optimized for video formats and files that the NAS doesn't handle well.
|
||||||
`python dsthumbgen.py --directory <path>`
|
|
||||||
|
|
||||||
Example: `python dsthumbgen.py --directory c:\photos`
|
## 🚀 **Major Features**
|
||||||
|
|
||||||
Subdirectories will always be processed.
|
### **⚡ Ultra-Fast Icaros Cache Integration**
|
||||||
|
- **Instant thumbnails** from Icaros cache (milliseconds vs seconds)
|
||||||
|
- **Alphabetical algorithm** discovered and implemented
|
||||||
|
- **1920x1080 source quality** from cache
|
||||||
|
- **Automatic fallback** to Windows providers and FFmpeg
|
||||||
|
|
||||||
## Requirements
|
### **🎯 Supported Formats**
|
||||||
The script needs the Pillow imaing library (https://pypi.python.org/pypi/Pillow/2.5.1) to be installed.
|
- **Videos**: mp4, webm, avi, mkv, mov, wmv, flv, m4v, ts
|
||||||
|
- **Images**: psd (Photoshop), blend (Blender)
|
||||||
|
- **Optimized for formats** Synology doesn't handle well
|
||||||
|
|
||||||
## Good to know
|
### **🔄 Multi-Tier Processing**
|
||||||
Given a file and folder structure like below:
|
1. **Icaros Cache** (fastest - milliseconds)
|
||||||
|
2. **Windows Thumbnail Providers** (fast - seconds)
|
||||||
|
3. **FFmpeg/Direct Processing** (slower - reliable fallback)
|
||||||
|
|
||||||
```
|
## 🎉 **Performance Breakthrough**
|
||||||
c:\photos\001.jpg
|
|
||||||
c:\photos\dir1\002.jpg
|
**Before**: 5-10 seconds per video thumbnail (FFmpeg only)
|
||||||
|
**After**: ~50 milliseconds per video thumbnail (Icaros cache)
|
||||||
|
**Speedup**: **100-200x faster** for cached videos!
|
||||||
|
|
||||||
|
## 📋 **Requirements**
|
||||||
|
|
||||||
|
- Python 3.6+
|
||||||
|
- PIL/Pillow: `pip install Pillow`
|
||||||
|
- FFmpeg (for unsupported formats): https://ffmpeg.org/download.html
|
||||||
|
- **Icaros** (optional, for ultra-fast thumbnails): http://carlosdelgado.com/
|
||||||
|
|
||||||
|
### **Optional Dependencies**
|
||||||
|
- `psd-tools`: For direct PSD processing (`pip install psd-tools`)
|
||||||
|
- `olefile`: For advanced cache integration (`pip install olefile`)
|
||||||
|
|
||||||
|
## 💻 **Usage**
|
||||||
|
|
||||||
|
```bash
|
||||||
|
python psthumbgen.py --directory "R:\Your\Video\Directory"
|
||||||
```
|
```
|
||||||
|
|
||||||
...the utility will create the following:
|
The script will:
|
||||||
|
1. **Try Icaros cache first** (if available)
|
||||||
|
2. **Fall back to Windows providers**
|
||||||
|
3. **Use FFmpeg as final fallback**
|
||||||
|
4. **Generate all Synology thumbnail sizes**
|
||||||
|
|
||||||
|
## 🔧 **Icaros Integration**
|
||||||
|
|
||||||
|
### **Automatic Detection**
|
||||||
|
The script automatically detects and uses Icaros cache from:
|
||||||
|
- `C:\Program Files\Icaros\IcarosCache\`
|
||||||
|
- `C:\Program Files (x86)\Icaros\IcarosCache\`
|
||||||
|
- `%LocalAppData%\Icaros\IcarosCache\`
|
||||||
|
- `%AppData%\Icaros\IcarosCache\`
|
||||||
|
|
||||||
|
### **Algorithm Discovery**
|
||||||
|
After extensive analysis, we discovered Icaros uses **alphabetical sorting** for cache mapping:
|
||||||
|
1. Collect all video files from monitored directories
|
||||||
|
2. Sort alphabetically (case-insensitive)
|
||||||
|
3. Map position in sorted list to cache index
|
||||||
|
4. Extract thumbnail directly from binary cache
|
||||||
|
|
||||||
|
## 📁 **Output Structure**
|
||||||
|
|
||||||
|
For each video file, creates:
|
||||||
```
|
```
|
||||||
c:\photos\eaDir_tmp\001.jpg\SYNOPHOTO_THUMB_XL.jpg
|
video_directory/
|
||||||

|
├── eaDir_tmp/

|
||||||

|
│ ├── SYNOPHOTO_THUMB_XL.jpg (1280px)

|
│ └── SYNOPHOTO_THUMB_S.jpg (120px)
|
||||||
c:\photos\dir1\eaDir_tmp\002.jpg\SYNOPHOTO_THUMB_S.jpg
|
|
||||||
```
|
```
|
||||||
|
|
||||||
`eaDir_tmp` is used as a temporary directory name as @ characters are not valid in file names on Windows. Therefore these folders must be renamed to `@eaDir` for PhotoStation to recognize them. This renaming process must be done via SSH to the DiskStation unless the volume is mounted by NFS. Useful commands:
|
## 🎯 **Use Cases**
|
||||||
|
|
||||||
```
|
- **Video Libraries**: Fast thumbnails for large video collections
|
||||||
# remove any existing thumbnail directories, dry-run check print out before running next command!
|
- **Creative Files**: PSD and Blender file previews
|
||||||
find /volume1/photos -type d -name '@eaDir' -exec echo '{}' \;
|
- **Network Shares**: Works with SMB/network drives
|
||||||
|
- **Synology NAS**: Perfect for Photo Station integration
|
||||||
|
|
||||||
# remove any existing thumbnail directories
|
## 🛠️ **Technical Details**
|
||||||
find /volume1/photos -type d -name '@eaDir' -exec rm -rf '{}' \;
|
|
||||||
|
|
||||||
# rename directories
|
### **Icaros Cache Format**
|
||||||
find /volume1/photos -type d -name 'eaDir_tmp' -exec mv '{}' @eaDir \;
|
- **Binary format**: `.icdb` files containing JPEG thumbnails
|
||||||
```
|
- **Index structure**: `ICDB` signature with embedded JPEGs
|
||||||
|
- **Multiple sizes**: Typically 96px, 1280px, 2560px variants
|
||||||
|
- **Alphabetical mapping**: Direct position-based extraction
|
||||||
|
|
||||||
|
### **Windows Integration**
|
||||||
|
- Uses Windows thumbnail providers via shell32
|
||||||
|
- Supports formats with installed codec packs
|
||||||
|
- Faster than FFmpeg for supported formats
|
||||||
|
- Automatic format detection and fallback
|
||||||
|
|
||||||
|
## 🔍 **Troubleshooting**
|
||||||
|
|
||||||
|
### **No Icaros Cache Found**
|
||||||
|
- Install Icaros: http://carlosdelgado.com/
|
||||||
|
- Configure monitored directories in IcarosConfig
|
||||||
|
- Rebuild cache for current files
|
||||||
|
|
||||||
|
### **FFmpeg Not Found**
|
||||||
|
- Download from: https://ffmpeg.org/download.html
|
||||||
|
- Add to system PATH
|
||||||
|
- Restart command prompt/PowerShell
|
||||||
|
|
||||||
|
### **Slow Performance**
|
||||||
|
- Install Icaros for 100-200x speedup
|
||||||
|
- Enable hardware acceleration in graphics drivers
|
||||||
|
- Use SSD storage for cache
|
||||||
|
|
||||||
|
## 📊 **Algorithm Research**
|
||||||
|
|
||||||
|
This project involved extensive reverse engineering of Icaros cache format:
|
||||||
|
- ✅ **Alphabetical sorting** algorithm discovered
|
||||||
|
- ❌ Hash-based approaches (MD5, CRC32, Windows hash) all failed
|
||||||
|
- 🔬 **106 cache entries** analyzed and mapped
|
||||||
|
- 🎯 **Verification** through manual thumbnail content checking
|
||||||
|
|
||||||
