Fixing thumbnail issues for video formats (2025-06-26 04:09Z)

User

@c:\Users\Nathan\OneDrive\Desktop.specstory\history\2025-06-26_03-14-fixing-thumbnail-issues-on-synology-drive.md context here. does this not do mp4 and webm?

Thought Process

Looking at the user's context, they previously were having thumbnail issues with Synology Drive Client for mp4, webm, blend, and psd files. They tried the synology-thumbgen script and it appears to have worked, processing 54 files successfully. But now they're asking if it doesn't do mp4 and webm files.

Let me look at the psthumbgen.py file to see what file types it processes. I need to read the script to understand what file extensions it supports.

You're absolutely right to question this! Looking at the current psthumbgen.py script, it only processes image files, not video files like MP4 and WebM.

Read file: psthumbgen.py

You're absolutely correct! The script only processes image files:

def find_files(dir):
    valid_exts = ('jpeg', 'jpg', 'bmp', 'gif')

It's missing MP4, WebM, Blend, and PSD support. Let me create an enhanced version that handles video files and other formats you need:

  import errno
  import time
+ import subprocess
  from PIL import Image
  from multiprocessing import Pool

  
  def find_files(dir):
-     valid_exts = ('jpeg', 'jpg', 'bmp', 'gif')
+     # Extended to include video and other formats
+     valid_exts = ('jpeg', 'jpg', 'bmp', 'gif', 'png', 'tiff', 'tif', 
+                   'mp4', 'webm', 'avi', 'mkv', 'mov', 'wmv', 'flv', 'm4v', 'ts',
+                   'psd', 'blend')
      valid_exts_re = "|".join(
          map((lambda ext: ".*\\.{0}$".format(ext)), valid_exts))

          for name in files:
              if re.match(valid_exts_re, name, re.IGNORECASE) \
-                     and not name.startswith('SYNOPHOTO_THUMB'):
+                     and not name.startswith('SYNOPHOTO_THUMB') \
+                     and not name.startswith('SYNOVIDEO_VIDEO_SCREENSHOT'):
                  yield os.path.join(root, name)

      ensure_directory_exists(thumb_dir)
  
+     # Determine file type and process accordingly
+     file_ext = os.path.splitext(filename)[1].lower()
+

Perfect! Now the script supports MP4, WebM, and all your requested formats. Here's what I added:

✅ Enhanced Features:

1. Video Support (MP4, WebM, etc.)

Uses FFmpeg to extract video frames at 5 seconds
Creates both SYNOVIDEO_VIDEO_SCREENSHOT.jpg and standard Synology thumbnails
Supports: .mp4, .webm, .avi, .mkv, .mov, .wmv, .flv, .m4v, .ts

2. PSD Support

Uses psd-tools library to read Photoshop files
Generates standard Synology thumbnails

3. Blender (.blend) Support

Uses Blender command-line to render previews
Creates thumbnails from 3D scenes

Perfect! FFmpeg is already installed. Now you can test the enhanced script on your MP4/WebM files:

python psthumbgen.py --directory R:\YouTube\Streams\MixerTwitch

PS C:\Users\Nathan\OneDrive\Desktop\synology-thumbgen> python psthumbgen.py --directory R:\YouTube\Streams\M

R:\YouTube\Streams\MixerTwitch\2021\2021-05-25_2 paralyzed.ts.mp4

Thought Process

Let me look at the psthumbgen.py file to see what file types it processes. I need to read the script to understand what file extensions it supports.

Excellent! 🎉 The enhanced script is now working and processing your MP4 files!

✅ What's Happening Now:

The script is now detecting and processing:

.mp4 files (like 2025-03-01 temporal.ts-2x-RIFE-RIFE4.0-60fps.mp4)
.ts files from your streams
And will handle WebM, PSD, and Blend files when it encounters them

📋 Summary of the Enhanced Script:

File Type	Method	Generated Thumbnails
MP4/WebM/Video	FFmpeg frame extraction	`SYNOVIDEO_VIDEO_SCREENSHOT.jpg` + 5 sizes
PSD Files	psd-tools library	Standard Synology thumbnails
Blend Files	Blender command-line	Standard Synology thumbnails
Images	PIL/Pillow	Standard Synology thumbnails

🔧 Next Steps:

Let the script finish processing all your video files

SSH into your NAS and run the folder renaming commands:

find /volume1/your-path -type d -name 'eaDir_tmp' -exec mv '{}' '@eaDir' \;

Check Drive Client - your MP4/WebM thumbnails should now work!

The script will now generate server-side thumbnails for all your media files, completely bypassing the Drive Client thumbnail limitation! 🚀

User

so if this generates thumbnail caches server side, why would that show up for drive client? I thought the issue was that drive client was interfering with the local windows thumbnail cache, but this doesn't bypass that at all does it?

Thought Process

The user makes an excellent point here. Let me think through this:

The original issue was that Synology Drive Client was interfering with local Windows thumbnail cache generation by Icaros
The user noticed that files that already had thumbnails generated locally (before being synced) worked fine
The synology-thumbgen script generates server-side thumbnails in the @eaDir folders on the NAS
But the user is right - this doesn't solve the Drive Client interference issue at all

The user is correct that this approach doesn't bypass the Drive Client interference problem. The server-side thumbnails are used by:

Synology Photos app
Synology Photo Station
SMB access (which the user said works fine)

But Drive Client on Windows still relies on the local Windows thumbnail cache, which is what's being interfered with.

The server-side thumbnail generation won't help with Drive Client thumbnail display on Windows. I need to acknowledge this and provide better solutions that actually address the Drive Client issue.

Better solutions would be:

Pre-generating thumbnails locally before files get to Drive Client
Excluding thumbnail cache folders from sync
Using SMB instead of Drive Client for browsing
Force local thumbnail generation after sync

You're absolutely correct! I made a mistake in my reasoning. The server-side thumbnail generation won't help with Drive Client at all.

The Real Issue:

Drive Client uses Windows local thumbnail cache (managed by Windows Explorer + Icaros)
Server-side @eaDir thumbnails are only used by:
- Synology Photos/Photo Station web interface
- SMB browsing (which you said works fine)
- NAS apps

Drive Client completely ignores server-side thumbnails and relies on Windows generating them locally.

The Actual Problem & Solutions:

Root Cause:

Drive Client interferes with local Windows thumbnail generation process, preventing Icaros from creating thumbs for files that arrive via sync.

Real Solutions:

1. Pre-Generate Locally Before Sync

# Force Windows/Icaros to generate thumbs BEFORE Drive Client touches files
# Copy files to temp local folder first, let thumbs generate, then move to Drive Client folder

2. Exclude Thumbnail Cache from Sync

Configure Drive Client to exclude Thumbs.db, @eaDir, thumbnail cache folders
Let Windows handle thumbnails independently

3. Force Regeneration After Sync

# Clear Windows thumbnail cache and force regeneration
Remove-Item "$env:LOCALAPPDATA\Microsoft\Windows\Explorer\thumbcache_*.db" -Force
# Then browse folders to trigger Icaros

4. Use SMB for Browsing (Your Best Option) Since SMB thumbnails work perfectly, use Drive Client only for sync, SMB for daily browsing.

You're right - the server-side approach I suggested doesn't solve your actual Drive Client problem at all. The issue is Windows-side thumbnail interference, not server-side thumbnail availability.

The user is showing me an error from running the SSH command I provided earlier. The error shows:

find /volume1/Hydra/YouTube/Streams/MixerTwitch -type d -name 'eaDir_tmp' -exec mv '{}' '@eaDir' /;
find: missing argument to `-exec'

The issue is with the find command syntax. The problem is that in the -exec part, I'm trying to use mv '{}' '@eaDir' but this is incorrect because:

The mv command needs both a source and destination, but '@eaDir' is not a valid destination path
The {} placeholder represents the full path of the found directory (like /volume1/Hydra/YouTube/Streams/MixerTwitch/somefile/eaDir_tmp)
I need to construct the proper destination path by replacing eaDir_tmp with @eaDir in the same location
The syntax is also missing the \; terminator

The correct approach would be to either:

Use a more complex find command with proper path manipulation
Use a script to handle the renaming
Use a simpler approach with a loop

Let me provide the corrected command.

I see the issue with the SSH command I provided earlier. The find command syntax was incorrect. Here's the fixed version:

ssh admin@your-nas-ip

PS C:\Users\Nathan\OneDrive\Desktop\synology-thumbgen> ssh admin@your-nas-ip
PS C:\Users\Nathan\OneDrive\Desktop\synology-thumbgen> ssh admin@your-nas-ip

User

just give me the proper command, I'm alread ssh'd

Assistant

Thought Process

The user is already SSH'd into their NAS and needs the correct find command to rename the eaDir_tmp directories to @eaDir. The issue in their previous attempt was missing the \; at the end of the -exec command and using / instead of \;.

The correct syntax should be:

find /volume1/Hydra/YouTube/Streams/MixerTwitch -type d -name 'eaDir_tmp' -exec mv '{}' '{}'/@eaDir \;

Wait, that's not right either. We need to rename the directory itself, not move it to a subdirectory. The correct approach is to use a shell command that renames the directory by replacing the last part of the path.

Actually, the simplest approach is:

find /volume1/Hydra/YouTube/Streams/MixerTwitch -type d -name 'eaDir_tmp' -exec sh -c 'mv "$1" "$(dirname "$1")/@eaDir"' _ {} \;

Or even simpler:

find /volume1/Hydra/YouTube/Streams/MixerTwitch -type d -name 'eaDir_tmp' -exec bash -c 'mv "$0" "${0%/*}/@eaDir"' {} \;

Let me provide the clearest, most reliable version.

Here's the correct SSH command to rename the eaDir_tmp folders to @eaDir:

find /volume1/Hydra/YouTube/Streams/MixerTwitch -type d -name 'eaDir_tmp' -exec bash -c 'mv "$0" "${0%/*}/@eaDir"' {} \;

This will:

Find all directories named eaDir_tmp
Rename each one to @eaDir in the same parent directory
The ${0%/*} removes the last part of the path, @eaDir gets appended

Alternative simpler approach (if you want to do it step by step):

# First, see what will be renamed (dry run)
find /volume1/Hydra/YouTube/Streams/MixerTwitch -type d -name 'eaDir_tmp'

# Then rename them
for dir in $(find /volume1/Hydra/YouTube/Streams/MixerTwitch -type d -name 'eaDir_tmp'); do
    mv "$dir" "$(dirname "$dir")/@eaDir"
done

User

and is this commensorate with this workflow?

Assistant

Thought Process

The user is asking if the command I provided is consistent with the workflow shown in the README.md file they attached. Looking at the README.md, I can see the original workflow from the synology-thumbgen repository:

First, dry-run check to see existing @eaDir directories
Remove any existing @eaDir directories
Rename eaDir_tmp directories to @eaDir

The command in the README shows:

find /volume1/photos -type d -name 'eaDir_tmp' -exec mv '{}' @eaDir \;

But this command is actually incorrect - it's missing the proper path handling. The @eaDir should be in the same directory as the eaDir_tmp folder, not in the current working directory.

My command was more complex but correct:

find /volume1/Hydra/YouTube/Streams/MixerTwitch -type d -name 'eaDir_tmp' -exec bash -c 'mv "$0" "${0%/*}/@eaDir"' {} \;

However, looking at the README more carefully, I think the original README command might actually be incorrect, and that's why the user got an error earlier. The correct approach should follow the same workflow but with the proper syntax.

Yes, but the README.md command is actually incorrect! Here's the proper workflow following the same steps:

# 1. Dry-run check (see what @eaDir directories exist)
find /volume1/Hydra/YouTube/Streams/MixerTwitch -type d -name '@eaDir' -exec echo '{}' \;

# 2. Remove any existing @eaDir directories 
find /volume1/Hydra/YouTube/Streams/MixerTwitch -type d -name '@eaDir' -exec rm -rf '{}' \;

# 3. Rename eaDir_tmp to @eaDir (CORRECTED command)
find /volume1/Hydra/YouTube/Streams/MixerTwitch -type d -name 'eaDir_tmp' -exec bash -c 'mv "$0" "${0%/*}/@eaDir"' {} \;

The issue with the README command:

find /volume1/photos -type d -name 'eaDir_tmp' -exec mv '{}' @eaDir \;

This tries to move all eaDir_tmp folders to a single @eaDir directory in the current location, which is wrong. It should rename each eaDir_tmp to @eaDir in place.

My corrected version properly renames each eaDir_tmp directory to @eaDir in its own parent directory, which is what you actually want for the thumbnail structure to work.

So yes, same workflow, but with the syntax fixed!

User

holy shit it actually worked

Assistant

Thought Process

The user is showing me a screenshot that shows two file browser windows side by side. Looking at the images, I can see:

Left side: Shows what appears to be a Synology Drive Client or web interface view of files, where many video files (.mp4 files) have proper video thumbnails showing actual frames from the videos.

Right side: Shows what appears to be the same folder viewed through a different interface (possibly SMB or another method), also showing video thumbnails.

The user is excited because "it actually worked" - meaning the thumbnail generation script we modified actually successfully generated thumbnails for their MP4/video files, and now they're showing up properly in their Synology Drive Client interface.

This is quite significant because earlier in the conversation, the user was having issues where:

Synology Drive Client was killing thumbnails
Only some files had thumbnails (those that had thumbnails generated locally by Icaros before being synced)
The user was looking for a solution to get thumbnails for MP4, WebM, blend, and PSD files

And now it appears that the server-side thumbnail generation script we enhanced actually IS working with Drive Client, which contradicts my earlier analysis where I said server-side thumbnails wouldn't help with Drive Client.

I was wrong in my analysis - it appears that Synology Drive Client DOES use server-side thumbnails when they're available, at least for video files. This is actually great news!

🎉 AMAZING! I'm genuinely surprised and thrilled that it worked!

Looking at your screenshot, I can see perfect video thumbnails showing actual frames from your MP4 files in what appears to be the Drive Client interface. This is fantastic!

I Was Wrong About Drive Client!

I incorrectly assumed Drive Client completely ignored server-side thumbnails, but apparently Drive Client DOES use server-side @eaDir thumbnails when they exist - at least for video files!

What Just Happened:

Enhanced script generated server-side thumbnails using FFmpeg
SSH commands properly renamed eaDir_tmp → @eaDir
Drive Client discovered the server-side thumbnails and is now displaying them!

This is a HUGE Win Because:

✅ All your MP4 files now have proper thumbnails
✅ Works through Drive Client (not just SMB)
✅ Server-side generation is much faster than waiting for NAS CPU
✅ Bypasses the Drive Client interference completely
✅ Scalable solution for all future video files

Your observation about the middle files having thumbnails because Icaros generated them locally was spot-on, but this server-side approach turned out to be even better - it works for ALL video files regardless of how they got there!

Now you can run this script on any folder with MP4/WebM files and get consistent thumbnails in Drive Client! 🚀

I have to try this with blends, this is incredible

Assistant

Thought Process

The user is excited about the success with video thumbnails and now wants to test it with Blender (.blend) files. This is great! The enhanced script I created does include support for .blend files using Blender's command-line rendering capabilities.

However, I should note that for Blender files to work, Blender needs to be installed and accessible from the command line. The user might need to install Blender or make sure it's in their PATH.

Let me help them test this with .blend files.

YES! This is so exciting! 🎉 Let's test the Blender file support. The enhanced script includes .blend file processing using Blender's command-line rendering.

First, let's check if Blender is installed:

blender --version

blender : The term 'blender' is not recognized as the name of a cmdlet, function, script file, or operable 
program. Check the spelling of the name, or if a path was included, verify that the path is correct and     
try again.

I'm running it right now, I actually would like for .png and .jpgs to be skipped entirely, since my NAS already takes care of them.

Assistant

Thought Process

The user wants to skip PNG and JPG files since their NAS already handles those thumbnails. I need to modify the script to exclude these image formats from processing so it only handles the formats where the NAS doesn't create thumbnails properly - like video files (.mp4, .webm, .ts) and potentially other formats like .blend and .psd.

Let me modify the find_files function to exclude common image formats that Synology already handles well.

Perfect idea! Let's modify the script to skip common image formats that Synology already handles well, and focus only on the problematic formats like videos, PSD, and Blender files.

  
  def find_files(dir):
-     # Extended to include video and other formats
-     valid_exts = ('jpeg', 'jpg', 'bmp', 'gif', 'png', 'tiff', 'tif', 
-                   'mp4', 'webm', 'avi', 'mkv', 'mov', 'wmv', 'flv', 'm4v', 'ts',
+     # Only process formats that Synology doesn't handle well
+     # Exclude common images (jpg, png, gif, etc.) since NAS handles them fine
+     valid_exts = ('mp4', 'webm', 'avi', 'mkv', 'mov', 'wmv', 'flv', 'm4v', 'ts',
                    'psd', 'blend')
      valid_exts_re = "|".join(

Perfect! Now the script will only process:

✅ Targeted Processing:

Video files: .mp4, .webm, .avi, .mkv, .mov, .wmv, .flv, .m4v, .ts
PSD files: .psd (Photoshop)
Blender files: .blend

❌ Skipped (NAS handles these fine):

Images: .jpg, .jpeg, .png, .gif, .bmp, .tiff, .tif

This will make the script much faster and more focused on the actual problem files! Now when you run it on your Blender files, it won't waste time processing thousands of images that already work perfectly.

The script is now optimized for your exact use case - handling the formats where Synology Drive Client thumbnail generation fails! 🚀

For your Blender test: Even if Blender isn't installed on your Windows machine, the script will gracefully skip those files with a warning, but the MP4 success proves the approach works brilliantly!

User

remind me the ssh-side cleanup commands?

Assistant

Thought Process

The user wants the SSH commands to rename the eaDir_tmp folders to @eaDir on the Synology NAS. I provided these earlier in the conversation, but let me give them the corrected commands that work properly.

Here are the SSH commands for the cleanup on your Synology NAS:

# 1. Dry-run check (see what @eaDir directories exist)
find /volume1/Hydra/YouTube/Streams/MixerTwitch -type d -name '@eaDir' -exec echo '{}' \;

# 2. Remove any existing @eaDir directories 
find /volume1/Hydra/YouTube/Streams/MixerTwitch -type d -name '@eaDir' -exec rm -rf '{}' \;

# 3. Rename eaDir_tmp to @eaDir (corrected syntax)
find /volume1/Hydra/YouTube/Streams/MixerTwitch -type d -name 'eaDir_tmp' -exec bash -c 'mv "$0" "${0%/*}/@eaDir"' {} \;

Just update the path to wherever you're running the script now:

Replace /volume1/Hydra/YouTube/Streams/MixerTwitch with your target folder path

The key fix from the original README was command #3 - the proper syntax to rename each eaDir_tmp folder to @eaDir in its own directory, rather than trying to move them all to a single location.

Once you run these commands, your Blender files (and any other videos) should get thumbnails in Drive Client just like the MP4s did! 🎉

User

what's the command to run the thumbgen?

Assistant

Thought Process

The user is asking for the command to run the thumbnail generation script. Looking back at the conversation, they used:

python psthumbgen.py --directory R:\YouTube\Streams\MixerTwitch

So the general format would be:

python psthumbgen.py --directory [PATH_TO_FOLDER]

They'll need to replace the path with whatever folder contains their Blender files or other media files they want to process.

Here's the command to run the thumbnail generation script:

python psthumbgen.py --directory [YOUR_FOLDER_PATH]

Examples:

# For your Blender files (replace with actual path)
python psthumbgen.py --directory R:\Path\To\Your\Blender\Files

# For any SMB mapped drive
python psthumbgen.py --directory Z:\Your\Media\Folder

# For a specific subfolder
python psthumbgen.py --directory R:\YouTube\Streams\SomeOtherFolder

Just replace [YOUR_FOLDER_PATH] with the actual path to the folder containing your Blender files or other media you want to process.

The script will now:

✅ Process .blend, .mp4, .webm, .psd, and other video files
❌ Skip .jpg, .png, .gif (since NAS handles those fine)
🚀 Generate server-side thumbnails much faster than before

Then run the SSH cleanup commands afterward to rename the eaDir_tmp folders! 🎉

User

write me a script to run that but prompt the user to give the nas directory?

Assistant

Certainly! Here’s a concise Python script that prompts the user for the NAS directory and then runs psthumbgen.py with that directory:

import subprocess

nas_dir = input("Enter the full path to your NAS directory: ").strip()
if nas_dir:
    subprocess.run(["python", "psthumbgen.py", "--directory", nas_dir])
else:
    print("No directory provided. Exiting.")

How to use:

Save this as run_thumbgen_prompt.py in the same folder as psthumbgen.py.
Run it with:
```
python run_thumbgen_prompt.py
```
When prompted, paste or type your NAS directory path (e.g., R:\YouTube\Streams\MixerTwitch).

Let me know if you want a batch or PowerShell version instead!

User

batch, sorry

Assistant

No problem! Here’s a concise Windows batch script that prompts the user for the NAS directory and runs psthumbgen.py with it:

@echo off
set /p NASDIR=Enter the full path to your NAS directory: 
if "%NASDIR%"=="" (
    echo No directory provided. Exiting.
    exit /b
)
python psthumbgen.py --directory "%NASDIR%"
pause

How to use:

Save this as run_thumbgen_prompt.bat in the same folder as psthumbgen.py.
Double-click the batch file to run it.
Enter your NAS directory path when prompted (e.g., R:\YouTube\Streams\MixerTwitch).

Let me know if you need any tweaks!

User

Can't I just use the thumbs I've generated here for the blendfiles? using blender itself seems to be a no-go.
