# Fixing thumbnail issues for video formats (2025-06-25 22:09:21) _**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? --- _**Assistant**_ --- 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**: ```60:61:psthumbgen.py def find_files(dir): valid_exts = ('jpeg', 'jpg', 'bmp', 'gif') ``` It's **missing MP4, WebM, Blend, and PSD** support.

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 ## **📋 Prerequisites to Install:** --- ```bash pip install psd-tools ``` ``` PS C:\Users\Nathan\OneDrive\Desktop\synology-thumbgen> pip install psd-tools Defaulting to user installation because normal site-packages is not writeable Requirement already satisfied: psd-tools in c:\users\nathan\appdata\roaming\python\python312\site-packages ( 1.10.7) Requirement already satisfied: docopt>=0.6.0 in c:\users\nathan\appdata\roaming\python\python312\site-packag es (from psd-tools) (0.6.2) Requirement already satisfied: attrs>=23.0.0 in c:\users\nathan\appdata\roaming\python\python312\site-packag Requirement already satisfied: scikit-image in c:\users\nathan\appdata\roaming\python\python312\site-package s (from psd-tools) (0.25.2) Requirement already satisfied: networkx>=3.0 in c:\users\nathan\appdata\roaming\python\python312\site-packag es (from scikit-image->psd-tools) (3.4.2) Requirement already satisfied: imageio!=2.35.0,>=2.33 in c:\users\nathan\appdata\roaming\python\python312\si te-packages (from scikit-image->psd-tools) (2.37.0) Requirement already satisfied: tifffile>=2022.8.12 in c:\users\nathan\appdata\roaming\python\python312\site- packages (from scikit-image->psd-tools) (2025.3.30) Requirement already satisfied: packaging>=21 in c:\users\nathan\appdata\roaming\python\python312\site-packag es (from scikit-image->psd-tools) (24.2) Requirement already satisfied: lazy-loader>=0.4 in c:\users\nathan\appdata\roaming\python\python312\site-pac kages (from scikit-image->psd-tools) (0.4) PS C:\Users\Nathan\OneDrive\Desktop\synology-thumbgen> ``` --- Great! **psd-tools** is already installed. You'll also need **FFmpeg** for video support: --- ```bash ffmpeg -version ``` ``` PS C:\Users\Nathan\OneDrive\Desktop\synology-thumbgen> ffmpeg -version nable-mediafoundation --enable-libass --enable-libfreetype --enable-libfribidi --enable-libharfbuzz --enable -libvidstab --enable-libvmaf --enable-libzimg --enable-amf --enable-cuda-llvm --enable-cuvid --enable-dxva2 --enable-d3d11va --enable-d3d12va --enable-ffnvcodec --enable-libvpl --enable-nvdec --enable-nvenc --enableb libavcodec 61. 19.101 / 61. 19.101 libavfilter 10. 4.100 / 10. 4.100 libswscale 8. 3.100 / 8. 3.100 libswresample 5. 3.100 / 5. 3.100 libpostproc 58. 3.100 / 58. 3.100 PS C:\Users\Nathan\OneDrive\Desktop\synology-thumbgen> ``` --- Perfect! **FFmpeg is already installed**. Now you can test the enhanced script on your MP4/WebM files: --- ```bash 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\2025-03-01 temporal.ts-2x-RIFE-RIFE4.0-60fps.mp4 R:\YouTube\Streams\MixerTwitch\2018\2018-12-28_1 past_bedtime.ts.mp4 R:\YouTube\Streams\MixerTwitch\2020\2020-06-07 cmd.ts.mp4 R:\YouTube\Streams\MixerTwitch\2018\2018-12-28_2 rebellious_isp.ts.mp4 R:\YouTube\Streams\MixerTwitch\2021\2021-05-25_2 paralyzed.ts.mp4 ``` --- --- 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:** 1. **Let the script finish** processing all your video files 2. **SSH into your NAS** and run the folder renaming commands: ```bash find /volume1/your-path -type d -name 'eaDir_tmp' -exec mv '{}' '@eaDir' \; ``` 3. **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? --- --- --- 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** ```powershell # 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** ```powershell # 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. --- _**User**_ --- _**Assistant**_ --- I see the issue with the SSH command I provided earlier. The `find` command syntax was incorrect. Here's the fixed version: --- ```bash 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**_ --- Here's the correct SSH command to rename the `eaDir_tmp` folders to `@eaDir`: ```bash find /volume1/Hydra/YouTube/Streams/MixerTwitch -type d -name 'eaDir_tmp' -exec bash -c 'mv "$0" "${0%/*}/@eaDir"' {} \; ``` This will: 1. Find all directories named `eaDir_tmp` 2. Rename each one to `@eaDir` in the same parent directory 3. The `${0%/*}` removes the last part of the path, `@eaDir` gets appended **Alternative simpler approach** (if you want to do it step by step): ```bash # 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**_ --- Yes, but the **README.md command is actually incorrect**! Here's the proper workflow following the same steps: ```bash # 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:** ```bash 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**_ --- 🎉 **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:** 1. **Enhanced script** generated server-side thumbnails using FFmpeg 2. **SSH commands** properly renamed `eaDir_tmp` → `@eaDir` 3. **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!** 🚀 --- _**User**_ I have to try this with blends, this is incredible --- _**Assistant**_ --- **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:** --- ```bash 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. At line:1 char:1 + blender --version + ~~~~~~~ + CategoryInfo : ObjectNotFound: (blender:String) [], CommandNotFoundException + FullyQualifiedErrorId : CommandNotFoundException PS C:\Users\Nathan\OneDrive\Desktop\synology-thumbgen> ``` --- _**User**_ 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**_ --- 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. --- ```diff 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**_ --- Here are the SSH commands for the cleanup on your Synology NAS: ```bash # 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**_ --- Here's the command to run the thumbnail generation script: ```powershell python psthumbgen.py --directory [YOUR_FOLDER_PATH] ``` **Examples:** ```powershell # 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: ```python 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:** 1. Save this as `run_thumbgen_prompt.py` in the same folder as `psthumbgen.py`. 2. Run it with: ```powershell python run_thumbgen_prompt.py ``` 3. 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: ```batch @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:** 1. Save this as `run_thumbgen_prompt.bat` in the same folder as `psthumbgen.py`. 2. Double-click the batch file to run it. 3. Enter your NAS directory path when prompted (e.g., `R:\YouTube\Streams\MixerTwitch`). Let me know if you need any tweaks! ---
