Fix thumbnail generation and script creation (2025-10-12 21:53Z)

User (2025-10-12 21:53Z)

@2025-09-28_20-12Z-fixing-thumbnail-generation-and-sync-issues.md I have some more thumbs to generate in C:\Users\Nathan\SynologyDrive\YouTube\Streams\MixerTwitch\2025 let's do some things:

• disable funcitonality for webm since synology doesn't even support thumbnailing for it
• create a shell script that does the opposite of nascleanup.sh; it extracts the eadir@ to eadir_tmp so the thumbgen skips the existing frames instead of recalculating them again

Clarifying user requests

I see the user has two tasks to tackle. First, they want to disable functionality for .webm files in the psthumbgen.py script, which handles thumbnail generation. This means we should modify the code to skip processing .webm files, possibly through a config or flag.

Then, they mentioned creating a shell script that does the opposite of nascleanup.sh, transferring eadir@ to eadir_tmp so that thumbgen doesn't recalculate existing frames. Since they confirmed the need for a script, we’ll proceed with that. Planning file modifications

I need to open and read the psthumbgen.py file to find where .webm processing is managed. I'll use a method like read_file and possibly grep. I also need to create a shell script that does the opposite of nascleanup.sh, so I'll read that script to understand its functionality.

Next, I'll use multi_tool_use.parallel to simultaneously read both scripts. Since this is a multi-step task, I'll create two tasks: one for disabling .webm processing and another for adding the shell script that extracts EAs to eadir_tmp. I'll mark the first task as in progress before moving forward.

---

I’m going to scan psthumbgen.py to find where .webm handling is implemented, and read nascleanup.sh to mirror its logic for the new “extract eadir to eadir_tmp” script.

Adjusting functionality for webm

I need to disable functionality for webm files since Synology doesn't support thumbnailing for them. This means I’ll likely have to modify psthumbgen.py to skip .webm files. Currently, webm is included in valid_exts, so I'll need to adjust it to stop processing them—maybe by excluding webm from valid_exts or modifying the process_file video condition. The user wants to avoid wasting time on unsupported thumbnails, so skipping .webm entirely makes sense. Updating file handling and creating script

I just need to make minimal changes: first, I’ll remove 'webm' from valid_exts and adjust the video checks to exclude it. I should also update the Icaros helper sets so they avoid looking up '.webm'. They had heuristics referencing webm, but it’s probably fine to keep those unaffected since they’re for mapping. To be thorough, I’ll make sure to remove it from supported lists to simplify logic.

Next, I need to create a shell script that does the opposite of nascleanup.sh. This new script should extract the @eaDir to eaDir_tmp, letting thumbgen skip existing frames instead of recalculating them. It suggests copying the @eaDir directories and renaming them as eaDir_tmp alongside the originals. Clarifying directory extraction

The instructions say to "extract the eadir@ to eadir_tmp." There’s a minor typo, using "eadir@" instead of "@eaDir," but looking back at nascleanup, we see they used '@eaDir.' For our task, we want to copy/replace '@eaDir' with 'eaDir_tmp'.

I need to be cautious, though, since an existing 'eaDir_tmp' could be there. My plan is to create a corresponding 'eaDir_tmp' directory for each '@eaDir' subdirectory found. So, for each '@eaDir', I’ll set up a sibling 'eaDir_tmp' directory, keeping the structure intact. This way, we wouldn't overwrite anything already on the NAS, effectively preserving existing data. Creating extraction script

The user mentioned that we want to create a way for thumbgen to skip existing frames instead of recalculating them. The generator verifies if thumbnails already exist in eaDir_tmp and, if they do, it skips generating those sizes. In the code, both create_video_thumbnails and generate_synology_thumbnails check for pre-existence.

So, if we copy the contents from @eaDir to eaDir_tmp, our psthumbgen.py will see those files in 'eaDir_tmp' and bypass generating them. I'll need to create a new shell script for this purpose—perhaps I'll name it extract_eadir_to_tmp.sh, with an input directory path like nascleanup.sh. Creating extraction script details

First, I need to modify the extract_from_icdb_database by removing '.webm' from the get_alphabetical_position icaros_extensions set. I’ll create a patch with four separate hunks afterward.

Then, I’ll compose the new script extract_eadir_to_tmp.sh with a bash shebang. The usage will be $0 <directory>, and I'll use find to locate directories named '@eaDir'. For each found directory, I’ll set up a temporary directory and copy contents from @eaDir to eaDir_tmp using rsync if available, or fallback to cp if not. I’ll make sure to keep the output messages concise, avoiding excessive comments. Finally, I'll run read_lints on psthumbgen.py and update the necessary items.

---

I'll add todos for the two tasks, then disable .webm processing in psthumbgen.py, check for linter issues, and create the new extraction script that copies @eaDir to eaDir_tmp.

Evaluating webm functionality

I need to implement changes regarding webm functionality. The user mentioned that Synology doesn't support thumbnails for webm files, so I should disable processing for them. This means modifying the code to exclude .webm in the valid extensions list and in the file processing functions. If they’re not supported, generating thumbnails would just be a waste of effort. So, I’ll remove webm from valid_exts and associated lists in the code. Adjusting webm settings

I’m considering the processing of .webm in the Icaros helper sets. Although it’s included only for mapping, it’s clear that the user wants to disable functionality for webm entirely since Synology doesn’t support thumbnailing. So, I’ll modify the code to exclude .webm from valid_exts, process_file, and supported_exts to prevent any confusion or log spam if the function is mistakenly called. Even though it’s not critical, removing it will streamline things. Completing webm adjustments and scripting

I need to remove all occurrences of .webm in both find_files and process_file lists for thoroughness. I’ll also add disclaimers to comments about earlier tasks, but I'll keep it minimal. Then, I am tasked with creating a shell script that extracts '@eaDir' directories to 'eaDir_tmp' for thumbgen to skip existing frames. This script should replicate any existing '@eaDir/filename' into 'eaDir_tmp/filename'. I’m considering whether to copy those files or create symlinks instead. Clarifying file duplication process

On Synology Linux, when handling '@eaDir', I need to be careful not to lose thumbnail information. Since moving files could erase that data, making duplicates in 'eaDir_tmp' is a better approach by using copy instead of move. The copying process means retaining the original '@eaDir'.

I’ll need to copy the contents of '@eaDir/' into 'eaDir_tmp/' at the same directory level. This requires iterating through each '@eaDir' directory, creating sibling 'eaDir_tmp' folders if they don’t exist, and copying the contents accordingly. Implementing script and file edits

I want to invert the functionality of the existing nascleanup.sh to create a new script, extract_eadir_to_tmp.sh. This will find all '@eaDir' directories, create corresponding 'eaDir_tmp' folders, and copy the complete directory structure while preserving it. I’ll ensure that if thumbnails exist in 'eaDir_tmp', process_file will skip generating them again.

I also need to disable webm processing in psthumbgen.py and update valid_exts to remove '.webm'. While I need to keep comments minimal, I want to document the intentional exclusion of webm for clarity. Finally, I will apply the necessary changes and then run lints to ensure everything is correct.

---

I'm updating the code to skip .webm files, then I'll create the new extract_eadir_to_tmp.sh script that copies @eaDir into eaDir_tmp to pre-seed thumbnails.

Applying code changes

I’m planning to use apply_patch to add a new file while keeping in mind that comments should be minimal unless critical. A small header is okay, and I need to maintain indentation since it's a new file. The previous task disabled .webm, and I think skipping it in find_files and process_file should be enough. I'll run read_lints on psthumbgen.py after making changes and apply_patch to create the script. I’ll include status updates before tool calls throughout this process. Implementing user rules

I have two main actions: first, I’ll run read_lints, then create the file. While the order isn’t critical, I could run read_lints in parallel with nothing else, but starting with it seems more straightforward. The user's user_rules state that a script should only be generated if specified, and they did specify creating a shell script. I want to ensure the code remains concise and avoid heavy formatting. I’ll make changes using tools without directly outputting code, but I will provide a summary in my final message. Following instructions on code changes

Given that the environment uses code edit tools for file generation, the user will see it in the editor. The instructions specify that I should never output code to the user unless requested, and the user only asked to create a script, not to see the content. So I won’t print the script code. Now, I’ll focus on running read_lints and ensure everything is set up correctly before proceeding further!

---

I'll run a quick linter check on psthumbgen.py, then create the new extract_eadir_to_tmp.sh script that mirrors @eaDir into eaDir_tmp with existing thumbnails so psthumbgen.py skips regenerating them.

Creating shell script for Synology NAS

I need to develop a shell script that essentially reverses what nascleanup.sh does. This new script should copy contents from @eaDir to eaDir_tmp to allow thumbgen to skip recalculating existing frames. I see that we've already disabled webm in our Python code, which aligns with the initial requirements since Synology doesn't support thumbnailing for webm. The script should be in Bash and focus on ensuring that standard Synology thumbnail files are preserved in the eaDir_tmp path. Examining thumbnail directory structure

I need to look into how psthumbgen expects the thumb_dir to be structured. In process_file, thumb_dir is set to combine the base directory and filename under eaDir_tmp. So, for each file, the thumbnails should be in a specific path. We have to replicate the structure from @eaDir to eaDir_tmp. For each @eaDir directory, I’ll create a corresponding eaDir_tmp directory and copy over the necessary files, skipping any that already exist. The ultimate aim is to facilitate thumbgen in skipping existing thumbnail frames. I also need to ensure that permissions are set correctly on eaDir_tmp and create a script named extract_eadir_to_tmp.sh to accept the target directory path. Designing the extraction script

The script I'm conceptualizing shouldn’t stop services since it only involves read-only copying for extraction purposes. Although the NAS might restrict access, we can run it as a user. I’m outlining the script to be used like this: ./extract_eadir_to_tmp.sh /volume1/... or possibly a Windows path.

I need to validate the argument first, then look for any directories that contain @eaDir. For each of these directories, I’ll calculate the source and destination paths, ensuring the destination directory exists. I plan to copy relevant thumbnail files, specifically anything that matches SYNOPHOTO_THUMB_* and SYNOVIDEO_VIDEO_SCREENSHOT.jpg. To simplify, I think I’ll use the cp -n command to copy these files, mostly focusing on JPGs, since that's what Synology uses frequently. Refining the script with rsync

I realize I need to add the -n option to prevent overwriting any existing files during the copy process. I also have to be cautious about path names that might contain reserved characters. Using find with -print0 and reading with while read -d '' could simplify this.

Instead of basic copying, I think using rsync would be effective because it can maintain the directory structure while copying recursively. I’ll utilize options like --ignore-existing to skip files that are already there, and include the specific thumbnail patterns I need. However, I should note that mapping the source from @eaDir to the destination in eaDir_tmp might be tricky with rsync, and using --filter for transformations doesn’t seem straightforward. I’ll have to figure out a cleaner way to handle that. Looping through directories for extraction

I'm designing a script that will loop through the directories in @eaDir. The script starts by finding each @eaDir directory in the target location and then iterates through its entries, creating corresponding eaDir_tmp directories. For each known thumbnail file, I’ll check if it exists in the source directory and only copy it if the destination doesn't already have it.

After copying, I'll adjust permissions to make sure they are writable, as psthumbgen needs the destination directory to exist and be modifiable. I want to keep things simple by including a dry-run flag and respecting the user's request to generate this shell script. Once everything is structured properly, I'll apply the patch to add the new file and update the task list to complete.

---

I'll create a new extract_eadir_to_tmp.sh script that copies thumbnails from each @eaDir/<filename> into eaDir_tmp/<filename> without overwriting, so your Python thumbgen will skip regenerating existing images.

Providing file transfer instructions

I need to help the user with copying a file to their NAS using SCP, which seems to be failing. I wonder if SCP isn't enabled because the Synology's default SFTP is turned off. The error message "subsystem request failed on channel 0" suggests an issue with the SFTP subsystem. I'll instruct the user to enable SFTP in Control Panel under File Services. Also, it might help to check if SCP is set correctly over SSH, especially considering the version being used. Suggesting alternative solutions

I’m exploring alternatives for the user’s file transfer issue to their NAS. One option is to use ssh with heredoc or tee from PowerShell to create the script directly on the NAS. I also consider using rsync over SSH if it's installed, or copying via SMB share followed by an SSH command to change permissions. I'll provide clear commands to enable SFTP if it’s disabled and show how to transfer the script correctly with PowerShell. Presenting file transfer options

I’m looking at various options for the user to transfer their script to the NAS. Option A is to use SMB sharing with a PowerShell copy command and then SSH to change permissions on the file. Option B involves piping the script content directly via SSH. Finally, Option C suggests enabling SFTP and using SCP, but given the user’s current issue, providing the SMB or SSH piping methods seems like a quicker fix. I’ll give clear commands with minimal verbosity for each option. Drafting concise instructions

I need to explain to the user why the SCP command failed, which is due to the SFTP subsystem being disabled. Since earlier guidelines suggested keeping things short and focused, I'll provide three options for transferring files to the NAS. I think I should use code blocks for the commands to make it clearer. Even though there was a mention of summaries in the specs, I can skip that here as we're focusing directly on providing straightforward solutions for the user's query. Providing transfer command options

Here are the options for transferring your script to the NAS:

Option 1: SMB
In PowerShell, use:

Copy-Item "C:\Users\Nathan\Desktop\synology-thumbgen\extract_eadir_to_tmp.sh" "\\Hydra\home\extract_eadir_to_tmp.sh"

Then run:

ssh Hydra 'chmod +x /extract_eadir_to_tmp.sh && /extract_eadir_to_tmp.sh "/volume1/Hydra/YouTube/Streams/MixerTwitch/2025"'

Option 2: Pipe
Use:

Get-Content -Raw "C:\Users\Nathan\Desktop\synology-thumbgen\extract_eadir_to_tmp.sh" | ssh Hydra 'cat > /extract_eadir_to_tmp.sh'

Then run:

ssh Hydra 'chmod +x /extract_eadir_to_tmp.sh && /extract_eadir_to_tmp.sh "/volume1/Hydra/YouTube/Streams/MixerTwitch/2025"'

Option 3: Re-enable SCP
Go to DSM: Control Panel → File Services → FTP → Enable SFTP service, then rerun SCP. If Hydra isn’t in known_hosts, connect first to accept the host key. If admin restrictions are in place, ensure the home service is enabled for access to \\Hydra\home.

---

Likely SFTP is disabled on your NAS (scp now uses SFTP), so use one of these:

• SMB share (easiest)

Copy-Item "C:\Users\Nathan\Desktop\synology-thumbgen\extract_eadir_to_tmp.sh" "\\Hydra\home\extract_eadir_to_tmp.sh"
ssh Hydra 'chmod +x ~/extract_eadir_to_tmp.sh && ~/extract_eadir_to_tmp.sh "/volume1/Hydra/YouTube/Streams/MixerTwitch/2025"'

• Pipe file over SSH (no SFTP needed)

Get-Content -Raw "C:\Users\Nathan\Desktop\synology-thumbgen\extract_eadir_to_tmp.sh" | ssh Hydra 'cat > ~/extract_eadir_to_tmp.sh'
ssh Hydra 'chmod +x ~/extract_eadir_to_tmp.sh && ~/extract_eadir_to_tmp.sh "/volume1/Hydra/YouTube/Streams/MixerTwitch/2025"'

• Or enable SFTP in DSM: Control Panel → File Services → FTP → Enable SFTP service, then:

scp "C:\Users\Nathan\Desktop\synology-thumbgen\extract_eadir_to_tmp.sh" Hydra:~/extract_eadir_to_tmp.sh
ssh Hydra 'chmod +x ~/extract_eadir_to_tmp.sh && ~/extract_eadir_to_tmp.sh "/volume1/Hydra/YouTube/Streams/MixerTwitch/2025"'

Script ran successfully; the $'\r': command not found warning is from Windows line endings and doesn’t affect execution.

Run thumbnail generation:

python psthumbgen.py --directory "C:\Users\Nathan\SynologyDrive\YouTube\Streams\MixerTwitch\2025"

Or use your batch file:

.\autoThumbs.bat "C:\Users\Nathan\SynologyDrive\YouTube\Streams\MixerTwitch\2025"

The script copied existing thumbnails from @eaDir to eaDir_tmp, so psthumbgen.py will skip files that already have thumbnails and only process new ones. .webm files are skipped.

Modifying batch script

I need to adjust autoThumbs.bat to run the extraction shell script on NAS before the Windows psthumbgen runs. To do this, I'll use tools to edit the file. First, I want to read the content of autoThumbs.bat to understand how it currently works and what its arguments are. Then I’ll create a to-do list, which includes editing the batch script to invoke SSH and run extract_eadir_to_tmp.sh with the target directory coming from the provided argument.

Modifying autoThumbs.bat

I need to modify the autoThumbs.bat file to integrate the extraction shell (extract_eadir_to_tmp.sh). Currently, it has options 1, 2, 3, and 4, where options 2 and 3 offer manual SSH commands for cleanup. The new requirement is to run the extraction script on the NAS before generating thumbnails. I'll need to ensure options THUMBS_ONLY and BOTH call ssh Hydra for extraction. I also wonder if I should add a new option or integrate it into options 1 and 3. Modifying extraction options

I’m thinking about how to modify the options for BOTH and THUMBS_ONLY in the script to include an optional extraction step. However, THUMBS_ONLY suggests no SSH usage, even though the user asked to automatically run the extraction shell on NAS. I could add a new option 5 specifically for extracting to eaDir_tmp or adjust options 1 and 3 to run the extraction first via ssh Hydra. I also need to ensure that WINPATH conversion is added to THUMBS_ONLY, computing the NASPATH for the extraction command. I’m a bit unsure about the SSH user format—should it be 'Hydra' or 'nathan@hydra'? Clarifying SSH username

In the Windows terminal, using 'ssh Hydra' indicates I'm logging in with the username 'Nathan'—with a capital "N." This is important because the variable defined as NASUSER is 'nathan'—in lowercase. When connecting via 'ssh Hydra,' it would log me in as 'Nathan,' considering Windows OpenSSH defaults to the current Windows username. Since the extract script is in the home directory of 'Nathan,’ using 'ssh Hydra …' seems fine. However, since NASUSER is defined, I’m considering if using 'ssh %NASUSER%@hydra' might be safer. Addressing case sensitivity in SSH

I need to consider that Linux user accounts are case-sensitive, which means 'nathan' and 'Nathan' are different. However, it seems Synology may treat them as case-insensitive. Since using 'ssh Hydra' works for logging in as 'Nathan,' I think it’s best to stick with that to remain consistent. Although the autothumbs script echoes 'ssh nathan@hydra,' I’ll keep 'ssh Hydra.'

In the THUMBS_ONLY option, I’ll compute the NASPATH after reading WINPATH, then run the extraction script. It’s possible the script has CRLF, but it should still function; I’ll keep a check for that. Implementing extraction logic

I need to add logic for running the extraction script first, then generate thumbnails. If the script isn’t found, I should notify the user to upload it. So, I’ll create a command that echoes the extraction process and checks if the script exists using SSH.

For the THUMBS_ONLY and BOTH options, I'll compute the NASPATH initially, run the extraction, then the Python process. I also want to ensure manual cleanup steps remain intact, adjusting Option 3 to automatically run the extraction first. I'll make these edits in the autoThumbs.bat file while preserving the existing formatting. Let's implement that with care. Preparing for patch application

I'm preparing to insert the necessary code after line 30, converting the Windows path to the NAS path and running the extraction on NAS to seed eaDir_tmp. Then, in the BOTH option, I’ll change the order to compute the NASPATH first before SSH extraction, followed by the Python step. I’ll ensure to provide a status update before calling apply_patch since that’s part of the requirements. After this, I might summarize the changes and check if any action remains on our todo list. Let's proceed with the patch.

I'll update autoThumbs.bat to run the NAS extraction script before generating thumbnails for options 1 and 3 by computing the NAS path and invoking it over SSH. Then I'll summarize how to use it.

• Added NAS pre-seed step to autoThumbs.bat:
  • In options 1 and 3, it now converts the Windows path to a NAS path and runs ~/extract_eadir_to_tmp.sh "<NASPATH>" over SSH before calling psthumbgen.py.

Use:

• Option 1 or 3, enter your Windows path (e.g., R:\YouTube\Streams\MixerTwitch\2025). The script will pre-copy existing @eaDir thumbs into eaDir_tmp on Hydra, then generate only missing ones locally.

Evaluating SSH options

I see that option 2 prints manual commands, which means they want to run the batch automatically over SSH. I need to be careful here and consider running the extraction script instead. They might want both SSH cleanup and commands for removing @eaDir and moving eaDir_tmp. Earlier, we modified options 1 and 3 for extraction, so should we automate option 2 to run nascleanup.sh? But do we even have nascleanup.sh available on NAS, or do we need to copy it over? Revising SSH commands

I’m thinking of simplifying the batch process by using SSH to run inline find commands. However, I need to be careful with quoting in Windows. I've already computed NASPATH in option 2, so I can change option 2 to SSH with commands for finding and removing '@eaDir' and renaming 'eaDir_tmp' using bash. But quoting in Windows can be tricky. Since the user hasn't requested a new cleanup script, sticking with the existing extract_eadir_to_tmp.sh could be the best route for now. Implementing cleanup automation

For cleanup automation, I think inline commands would work better. After calculating NASPATH, I’d run SSH commands instead of just echoing them. I need to set it up to remove '@eaDir' and rename 'eaDir_tmp' on remote NAS. Quoting gets tricky in Windows, so I should simplify things and call nascleanup.sh if it’s present on NAS. However, it’s not copied there yet, so I can only call extract_eadir_to_tmp.sh for now. I might want to confirm before any destructive actions, but the user wants automation. Simplifying SSH implementation

I want to keep things minimal for the SSH implementation. First, I’ll compute NASPATH, which is already done. Next, I’ll run commands over SSH to remove existing '@eaDir' and move 'eaDir_tmp' to '@eaDir' while setting permissions if needed. We’ll stick to the earlier manual commands; no need to include line endings.

As for option 3, which is "Both," it still prints manual commands. However, I could consider updating this to run cleanup automatically after generating thumbnails, especially since I've integrated new extraction for options 1 and 3 as requested.

---

I'll update autoThumbs.bat to automatically run a cleanup step over SSH by invoking ~/nascleanup.sh on the NAS for options 2 and 3. If the script isn't present on the NAS, it will prompt you to upload it.

The model made no changes to the file.

Updating automation script

I need to update autoThumbs.bat for automating cleanup. Previous read_file shows manual echo instructions in both SSH_ONLY and BOTH sections, but our earlier patch already changed parts for options 1 and 3 to use extract_eadir_to_tmp. It seems the user selected option 2 and received manual echo instructions. So, I need to edit both SSH_ONLY and BOTH to execute automatic SSH commands instead of echoing. I should read the current autoThumbs.bat file again due to this patch mismatch.

---

I'll reload the current autoThumbs.bat to modify the SSH steps to run automatically instead of printing instructions, then apply targeted edits.

Updating cleanup automation

I need to update autoThumbs.bat to automate cleanup. The user asked if we can do this automatically, particularly in the SSH cleanup section or for both options. We previously tried to patch the file, but there was a context mismatch with the strings used.

Currently, the SSH_ONLY section is still showing manual commands, as does the BOTH section. I’ll modify these to invoke nascleanup.sh, which already exists in the repo and is designed for NAS cleanup tasks. Considering nascleanup.sh location

I noticed that nascleanup.sh is currently in the Windows workspace path, not on the NAS. For automation, I need to figure out whether it should already be on the NAS or if I need to copy it over using the SSH method we used before. The user specified that I shouldn't generate a new script unless requested, but I'm not creating one, just invoking the existing one. If the script isn't found, I can add logic to automatically upload it while keeping it simple. I’ll use a pipe method to do this effectively. Updating autothumbs.bat for cleanup

The user previously asked me to add the new extraction shell to autothumbs.bat, which we did. Now, they want to automate the cleanup process. We need to modify both the SSH_ONLY and BOTH sections to run the nascleanup.sh script directly on the NAS instead of printing manual commands. I'll also ensure that seeding is included as we already do in THUMBS_ONLY and BOTH. If the script is missing, I can add logic to check for it and upload it automatically with a fallback message if it's not found. Implementing automatic cleanup

The user wants to automate the process, so I'll update autoThumbs.bat to run nascleanup.sh directly. I need to apply the patch carefully with the right context, updating lines 62-72 and 99-109 to include the SSH command. I also want to maintain proper Windows batch quoting, as we used it successfully with the extraction script before. I’ll adapt that format to check if nascleanup.sh exists and run it; otherwise, I’ll echo a message that it's not found on the NAS. Patching nested quotes and cleanup

I need to make sure the quoting is correct, especially since we're dealing with double quotes inside double quotes in the batch file. In Windows batch scripting, the double-quoted string ends at the next quote, so I’ll need to use \" to escape those. I’ll patch the necessary sections by applying the proper updates. Additionally, I should include a status update for smooth tool usage. Since this is a code change, I don’t need to run lint checks on the .bat files, so I’ll implement the patch.

---

I'll update autoThumbs.bat so options 2 and 3 automatically run nascleanup.sh on the NAS instead of printing manual commands, matching how we already invoke the extraction script. Then I'll confirm the change.

• Updated autoThumbs.bat so:

  • Option 2: now automatically runs ~/nascleanup.sh "<NASPATH>" over SSH.
  • Option 3: seeds with extract_eadir_to_tmp.sh, runs psthumbgen.py, then automatically runs ~/nascleanup.sh "<NASPATH>".

If ~/nascleanup.sh isn’t on Hydra, you’ll see a message to upload it; copy your local nascleanup.sh to ~/nascleanup.sh (via SMB or the earlier SSH pipe method) and re-run.

Guiding file uploads

I need to help the user who has a blank query, but they’ve indicated a terminal output with options for SSH cleanup, and it seems like they want to upload nascleanup.sh to NAS. We might need to make it executable and possibly adjust their autoThumbs.bat for auto-uploading if the file is missing. I'll provide concise commands to assist with piping nascleanup.sh and ensuring it has the right line endings to avoid previous warnings. Let's make it clear and straightforward for them! Simplifying file handling

I’m thinking of how to send the script with PowerShell and possibly run dos2unix on the NAS, though it might not be available. Instead, I can use sed or perl to convert line endings. It makes sense to adjust autoThumbs.bat to auto-install nascleanup.sh by uploading it through SSH if it's missing. I'll include a PowerShell command to get the local file, convert CRLF to LF, and send it to the NAS. Automating this process should streamline everything for the user! Optimizing file handling with sed

I’m exploring options to manage line endings efficiently. We could run remote commands like sed to remove carriage returns, and using cat followed by sed might be simpler. My next step is to improve autoThumbs.bat by checking for nascleanup.sh and uploading it via PowerShell when necessary. I need to ensure that the syntax for embedding quotes in batch and PowerShell works, then push the file before attempting to run it. I'll refine my approach for clarity! Simplifying PowerShell commands

I'm working on crafting a PowerShell command to upload nascleanup.sh while ensuring it has the correct line endings. Escaping backticks can be complicated, so I’m considering alternate methods. One option is to use the type command in CMD to read the file and pipe it to ssh with tr -d \r to remove any carriage returns on the NAS. I think I’ll settle on using: type "%dp0nascleanup.sh" | ssh Hydra "tr -d '\r' > /nascleanup.sh" for simplicity. I just need to manage the quoting properly! Finalizing automated script changes

I’m focusing on ensuring that the remote files have the correct formatting and permissions. After uploading nascleanup.sh, I’ll run sed to remove CRLF and set execute permissions. The updated sequence will check if the script is executable, and if not, upload it unconditionally, since the file size is small. I’ll preserve indentation in the batch file and provide concise updates before tool calls. We’ll inform the user that autoThumbs.bat now auto-uploads nascleanup.sh and includes a fallback for manual upload. Let’s implement these changes!

I'll update autoThumbs.bat to automatically upload nascleanup.sh to Hydra (converting line endings) and then run it for options 2 and 3.

The model made no changes to the file.

Thought Process

Updating batch file process

I need to update the batch file to automatically upload nascleanup.sh if it's missing. It seems our attempt to apply the patch didn't work because of differing echo lines from previous changes. The current file still has manual commands in specific sections, especially lines 62-72 for SSH_ONLY and lines 99-109 for BOTH, which need replacing. Plus, I’ll make sure to add the upload command and fix CRLF with sed and chmod. Let's dig into the details! Considering SFTP and upload method

I need to remember that SFTP was disabled earlier. I can still use piping over SSH. For Windows batch commands, to redirect a local file into SSH, I could use: type "nascleanup.sh" | ssh Hydra "cat > /nascleanup.sh" or with input redirection: ssh Hydra "cat > /nascleanup.sh" < "%dp0nascleanup.sh". The first method outputs via CMD's pipe, while the latter is simpler. First, I'll check if nascleanup.sh exists locally, uploading only if it does. I'll ensure to handle quoting correctly! Running SSH commands for scripts

I’m planning to run a command to remove carriage returns from nascleanup.sh and make it executable with: ssh Hydra "sed -i 's/\r$//' /nascleanup.sh && chmod +x /nascleanup.sh && /nascleanup.sh "%NASPATH%"".

I'll also check the same for extract_eadir_to_tmp.sh since it exists on NAS. To be thorough, it might be good to upload it if it's missing, even though the user didn’t ask for that. I need to preserve the indentation style, which seems to be spaces instead of tabs. Let’s prepare to compose the apply_patch properly! Updating SSH_ONLY block

I need to replace the block under SSH_ONLY in the batch file. For lines 62-72, I’m planning to change the commands to ensure that nascleanup.sh is uploaded to NAS before running it. If it doesn’t exist locally, I’ll display an error message and then exit. I’ll also reinstate the necessary SSH commands to process the file.

I need to escape the percent signs and quotes properly while confirming I'm replacing the same for the BOTH section. Additionally, since there’s a request for automatic cleanup, I'll keep the user updated on the progress and final outcome! Editing existing script and updates

The user mentioned generating a script only if specified, but since we're editing an existing file, that's not an issue. The guideline to keep the code concise applies mainly to generated code, while our changes are minimal.

We need to make sure we include status updates based on the developer's instructions; I haven't been consistent with micro-updates during tool calls. For this call, I’ll add a micro-update before applying changes, but since apply_patch already failed once, I’ll focus on ensuring that the final message summarizes the changes made. Time to execute apply_patch with the targeted updates!

Modifying autoThumbs.bat

I need to address the user's query about autoThumbs.bat, where they mentioned that nascleanup.sh isn't found on NAS. It seems the user wants an automatic upload/run feature. I previously modified autoThumbs.bat to upload nascleanup.sh, but the patch failed repeatedly. So, according to the system guidance, I should use the edit_file function for this task. I have the current file content, and now I need to replace the sections that print manual commands to instead upload and run nascleanup.sh. Editing autoThumbs.bat

I need to make sure I'm following proper indentation and Windows batch file style for my edits. I'll add the command to upload via SSH using "cat > /nascleanup.sh" and convert line endings with sed, which is available on the NAS. The dos2unix command isn’t guaranteed, so I’ll stick with sed. I previously added a seeding step in THUMBS_ONLY and BOTH to run extract_eadir_to_tmp.sh, which is great! Now, I need to carefully create an edit using the edit_file tool, replacing specific lines while including comments to indicate unchanged code segments, even if it’s not typical for batch files. Creating edit snippets

I need to compose snippets that provide context along with new lines for the autoThumbs.bat edits. There are two sections to edit:

1. In the :SSH_ONLY section, I’ll replace the existing lines 62-72, which print manual instructions and go to END. I want to update this block to include the commands for uploading and executing.

2. In the :BOTH section after executing psthumbgen.py, I’ll replace lines 99-109, which also print manual instructions. It’s crucial to remember to use double quotes around the SSH command string and escape any percent signs in the batch script! Reviewing current content block

I'm looking at lines 62-72, which currently contain instructions for SSH cleanup commands. It starts with a reminder to run commands manually and shows a series of echo statements with specific SSH and find commands.

Notably, it includes a bash parameter expansion ${0%%/*}, as well as an earlier variant ${0%/*}, but since I'm updating this section, I'm going to remove those. Instead, I’ll replace this content with the new block for uploading and executing. Preparing edits for autoThumbs.bat

I'm set to replace the current block in the :SSH_ONLY section with new commands that upload and execute nascleanup.sh. I need to ensure proper percent expansion for %NASPATH% and manage quoting for the SSH command. Keeping the bash -lc structure consistent, I'll format the commands to avoid CRLF issues.

For both sections, I’ll prepare precise old_string values that include all relevant lines, ensuring I match the exact formatting. This method helps me reduce risks while using the edit_file function for two separate calls. I’m ready to implement the changes and keep the user informed!

---

I updated the plan to automatically upload and run nascleanup.sh via SSH in options 2 and 3. Now I'll apply the edits to autoThumbs.bat.

Addressing bash interpreter issue

I need to provide a fix for the user's bash error caused by CRLF line endings. Currently, we're using sed -i 's/\r$//' to eliminate these line endings, but it seems like the shebang line might still have CRLF, or maybe the file was reuploaded incorrectly. Sometimes busybox sed doesn't support -i, which could lead to this issue. I wrote a command to adjust it, but the error suggests the CR may have remained. Fixing bad interpreter error

The terminal is showing a "bad interpreter" error, indicating that sed might not have corrected the issue or that the shebang has a CR. A potential fix is to use dos2unix if it's available, or a more robust solution like tr -d '\r' to create a new file. Another option is using awk or even perl for the conversion, but not all systems have perl. I also need to ensure the shebang points to the correct interpreter on Synology. Implementing line-ending normalization

I’m considering a fallback approach using either dos2unix or sed to create a temporary file. It's important to implement line-ending normalization before setting execute permissions and running the script. I also want to address extract_eadir_to_tmp.sh, which had CRLF issues too. For the nascleanup.sh, since it fails, I’ll adjust the command in autoThumbs.bat to use an effective line-ending conversion process before executing it. I'll also make sure to handle the nested quoting properly in the command. Updating upload commands

I’ve already gone through the necessary code blocks for SSH_ONLY and BOTH sections. Now, I need to update both echo upload commands for nascleanup.sh. The current command uses a simple file transfer, but I'll adjust it to include a robust conversion method. I’ll check for dos2unix availability and apply that; if not, I’ll fall back on using tr to remove carriage returns. It also seems important to ensure the shebang line is proper, but since it starts with #!/bin/bash, it should generally work. Running it with an explicit bash can help if issues arise. Updating file lines and managing issues

The shebang error relates to the first line of the script. To bypass that, I can call it directly with bash, but I need to ensure line endings are converted first to avoid $'\r' errors. I'll perform file edits to substitute specific strings, taking care to include context lines.

I also need to handle extract_eadir_to_tmp.sh, which has similar CRLF issues. We should normalize its line endings when needed, but only do so if required. Additionally, for each tool call, I will include a brief status update indicating that I see the CRLF problem and am updating the batch accordingly. I'll skip creating a todo list for this small change. Finally, I’ll carefully construct the new and old strings for the needed edits while keeping quoting for batch safe. Maintaining proper escaping for commands

In our earlier solution, I used backslashes to escape quotes within a double-quoted string to ensure a literal quote is passed through. This approach remains crucial for handling \r and %NASPATH%. The command will now check for dos2unix, and if not available, it will use tr to clean up the line endings. It's essential to preserve that double backslash for safety as I perform two edit_file calls. I’ll also include a status update and a summary at the end for clarity.

---

I see the "bad interpreter: /bin/bash^M" due to CRLF line endings on the uploaded nascleanup.sh. I’ll update autoThumbs.bat to normalize line endings on the NAS (using dos2unix if available, else tr) before chmod +x and execution.

Adjusting the script for errors

I see the user is dealing with some error messages, and while they didn't provide a direct question, I believe they're looking for help with the nascleanup script. It seems we need to modify it to avoid errors when the eaDir_tmp directory doesn't exist—this should be straightforward. The permission denied error when modifying .noindex suggests we might need to address how permissions are set before attempting to make changes. Let's think through how to handle that more gracefully in the script. Revising the script process

The user is encountering issues with creating the .noindex file under @eaDir due to permission settings. The current process tries to change permissions before creating the file, which doesn’t work. We should create .noindex first. There’s also an issue with the synoservicectl command not being found, possibly due to path changes in different DSM versions. It might be best to adjust the script to check for the command's location and propose fixing the nascleanup.sh script to address these errors. Modifying the nascleanup script

I’m planning to modify the nascleanup.sh script that gets uploaded to the NAS. Right now, it stops services, clears the queue, lists @eaDir, removes it, then renames eaDir_tmp to @eaDir before setting permissions and creating the .noindex file. We need to move the .noindex creation step to happen before setting permissions. I also noticed that the rename command references $0 incorrectly; I'll change it to use $1 instead to avoid errors. This adjustment should help things work more smoothly. Improving script robustness

I see there's an error related to "eaDir_tmp: No such file or directory" from the find command, likely because it attempts to move a non-existent directory. This suggests we need a more robust approach for the renaming part. I plan to adjust the script to check if the directory exists before trying to rename it. Additionally, I’ll update the service stop commands for DSM 7 to ensure it uses the correct path for synoservicectl. Lastly, I’ll create the .noindex file before applying read-only permissions to avoid further issues. Planning code edits

I’m looking to add a .noindex file inside each @eaDir, and we can ignore permission denied errors while ensuring this happens before setting permissions. The user has mentioned using Hydra as the host, so I’ll keep that in mind for name consistency. I know we need to create a todo list with at least two items, so I'll split the tasks: one for reordering the chmod/.noindex steps and another for fixing the rename command and service control path. Once that’s done, I’ll update the nascleanup.sh script accordingly.

---

I'll fix the NAS script to avoid permission errors and missing file errors by reordering .noindex creation before chmod, making the rename robust, and making service control optional. Then I'll apply the edits.

Proposing Script Fixes

We need to respond to the user's message, but they only pasted some terminal output without a clear question. I’ll consider the need to fix the NAS script for permission errors. To be proactive, I can adjust nascleanup.sh to manage missing eaDir_tmp directories and avoid issues with .noindex in @eaDir. Also, they mentioned issues with service commands; we should keep in mind that their home user might not have the correct permissions or paths. Reviewing and Modifying Script

It looks like the upload for nascleanup.sh has been modified. The previous version stops services and manages the @eaDir directories, but I'm seeing some errors. One issue is that it couldn't find any eaDir_tmp directories to rename, which isn’t critical. Another problem is related to creating the .noindex file after changing permissions, which leads to access denials. We should create .noindex before setting the permissions to avoid this. Lastly, the user’s attempt to control the service needs adjusting, as they got a command not found error; I'll make sure to clarify that for them. Analyzing Rename Command

The rename command in nascleanup.sh has some issues. It uses find to locate eaDir_tmp, but the syntax with bash -c is problematic. The $0 variable refers to the script name, not the positional parameter as intended. Typically, I should use $1 for the first argument. It seems they've used {} incorrectly, leading to potential failures when attempting to rename. The logs indicate missing directories, which could be due to either quotes not being properly placed or trying to stat non-existent files. Fixing the Rename Command

I need to update the rename command. Using -execdir or modifying with bash -c could work, but a simpler approach involves using find with a while loop to rename eaDir_tmp. This means I’ll move directories without needing complicated execution.

We should also consider whether the user will upload the edited file, but since we have automatic upload in place, that should be fine. Additionally, stopping services with sudo might cause issues for a non-sudo user. It seems there are no errors logged, which is okay, but we should ensure .noindex is created before changing permissions. Updating Script for Robustness

For the eaDir_tmp issue, it's good that the script won't fail if none exist, but we should tweak it to avoid the "No such file or directory" message from find. Switching to a while read loop will help avoid those errors. I’ll adjust the nascleanup.sh to incorporate that change and ensure we create .noindex before setting permissions. Also, we want to keep service control optional since some commands may not be found. Lastly, I'll make sure to include status updates before tool calls and proceed with the necessary edits while reporting back to the user about the fixes.

---

I'll update nascleanup.sh to fix the rename logic, create .noindex before chmod, and guard service control commands, then confirm how to re-run via autoThumbs.

Evaluating script modifications

I need to modify the nascleanup.sh script, specifically moving the .noindex command before the chmod command to avoid a permission denied error when adding .noindex while the directory is still writable. I'll also ensure that we handle missing eaDir_tmp silently since find already prints errors. I need to look at the error messages indicating that certain paths don't exist and investigate whether quoting or symlinks might be causing issues. Investigating directory errors

I realize that the "No such file or directory" message from find might occur when directory names include CRLF or due to permission issues causing traversal failures. The way -exec bash -c passes {} as $0 seems fine, allowing me to get the parent directory. However, I’m puzzled why find shows errors for eaDir_tmp later on as it tries to prune. It could indicate that there weren’t any eaDir_tmp directories to begin with. To silence these errors, I can add 2>/dev/null or use -print0 with a loop for checks. Modifying script logic

I’m considering whether some directories are being modified concurrently, which could lead to issues. However, it's not crucial to fix that right now. I realize the creation of .noindex fails due to a permission denied error because chmod 555 is set on @eaDir beforehand. I should move the creation step before chmod.

I also note that service stop commands use sudo, which might not be configured correctly for non-root users on DSM 7. It seems I could either remove service commands or check if they exist before attempting to use them.

In updating nascleanup.sh, I need to ensure .noindex is created before chmod, adjust the service section to only run if commands are found and without sudo, and also make the rename process more robust to avoid errors. Finally, I should ensure files are set to read-only afterward. Implementing script changes

The .noindex has been created. I’m considering adding a step to create directories for @eaDir if they’re missing during the move. The current move operation uses mv "$0" "${0%/*}/@eaDir", which could conflict if @eaDir already exists, but we did remove any existing @eaDir earlier, so that’s good.

For stopping services, I'll replace the stop lines with a check to see if synoservicectl exists before trying to stop the services. If it requires sudo, that might be a problem since I'm running as a standard user, and it likely won’t have permission. Implementing script modifications

I'm considering an approach where we can optionally try without sudo, and if that fails, we could skip or let the user acknowledge. I'll reorder steps to create .noindex before changing permissions with chmod 555. To suppress missing errors from find, I'll add 2>/dev/null, since errors about missing directories likely come from broken symlinks. I also need to ensure we're using positional parameters correctly.

I’ll guard the service commands with proper checks, update the clear indexing queue permissions, and avoid suggesting starting indexing services at the end. Then, I’ll execute these changes and ensure to provide a brief summary afterward. I’ll also mark two tasks as completed!

---

I’m going to fix nascleanup.sh to handle DSM 7 better: guard service control, reorder .noindex before chmod, and make the rename robust and quiet. Then I’ll mark the related todos done.

• I updated nascleanup.sh:
  • Service control is best-effort (handles DSM7 or skips).
  • .noindex is created before chmod to avoid permission denied.
  • Rename from eaDir_tmp to @eaDir is depth-first and robust; missing eaDir_tmp dirs won’t error.

Re-run from autoThumbs.bat:

• Option 2 (SSH cleanup only) or 3 (seed + generate + cleanup). It will upload the updated nascleanup.sh, normalize line endings, chmod, and run it automatically.

Exploring thumbnail issues

To show new thumbnails in Explorer, I need to ensure that Windows caches are updated, which might involve clearing the thumbcache or restarting Explorer. The problem of "no new thumbs appear" suggests that the autoThumbs process didn’t generate new thumbnails, possibly because webm support is disabled on Synology. If they’re accessing files through a mapped drive, Explorer might rely on Synology CFAPI, which could be affected by earlier changes. It's a bit confusing because Explorer and Synology thumbnails are separate. Clarifying thumbnail generation

The script is extracting from the Windows provider to create Synology thumbnails, not updating Windows thumbnails. The user expected Explorer thumbnails to update after running it, and they previously noted that autothumbs seemed to work great. This might be because Explorer reads from the Windows central cache, but the actual thumbnail generation doesn’t impact Explorer. If they’re looking for thumbnails for local files in Windows, it won't read those unless they're accessible through specific paths. If Icaros can’t generate for network files, that adds to the complexity. Investigating thumbnail generation

The lack of new thumbnails might stem from PSTHUMBGEN skipping processing due to webm being disabled, which affects many files in the specified path. The user previously requested disabling webm, so this makes sense. They want thumbnails for other formats like mp4 and ts, but if the folder primarily contains .webm files, that would explain why new thumbnails aren’t appearing in Explorer. They mentioned it was working great before, possibly for NAS seeding. It might be beneficial to verify the logs for any output from PSTHUMBGEN and check for generated files using PowerShell commands. Examining thumbnail visibility in Explorer

I could suggest forcing a rebuild of the Explorer thumbnail cache, even though they did that earlier. If they want Explorer to show thumbnails for .webm files, that's tricky since we've disabled that feature. While Windows might display them due to Icaros, our processing is only for Synology. They had past issues with Explorer showing icons instead of thumbnails, which might have been due to cloud provider interactions. Their process involves seeding thumbnails from NAS, but synchronization could delay the visibility of created thumbnails until completed. Concise troubleshooting steps

I should provide some straightforward troubleshooting steps based on the user's brief request.

First, I need to confirm if psthumbgen processed any files. If none, webm is disabled, so re-enable it if thumbnails are desired. If it processed files yet Explorer still doesn’t show them, I should recommend restarting Explorer and clearing the thumbnail cache.

It's important to view files in the local SynologyDrive, ensure on-demand is off, and confirm Icaros is enabled for .mp4. If Synology Photos are expected to show thumbnails, I’ll check that nascleanup ran successfully.

Additionally, if there's an error with directories not showing up, I need to emphasize that Explorer thumbnails are independent from Synology's @eaDir.

---

• Windows Explorer doesn’t use @eaDir at all; autothumbs only affects Synology Photos. So Explorer won’t “pick up” the new Synology thumbnails.

Do this for Explorer thumbnails:

• Ensure files are local (no cloud placeholders):

attrib +P -U /S /D "C:\Users\Nathan\SynologyDrive\YouTube\Streams\MixerTwitch\2025\*"

• Refresh Windows’ cache:

taskkill /IM explorer.exe /F
Remove-Item "$env:LOCALAPPDATA\Microsoft\Windows\Explorer\thumbcache_*.db" -Force -ErrorAction SilentlyContinue
Start-Process explorer.exe

• Note: We disabled .webm in psthumbgen.py. Explorer thumbnails for .webm still depend on Icaros (not our script). If most files are .webm, you won’t see changes from autothumbs in Explorer.

Assessing generation options

It seems they didn't run the generation process. Option 2 is only for cleanup on NAS and it tried to rename directories that didn't exist. The fix is to run either option 1 or option 3 to generate local thumbnails. Option 3 will seed and clean up, creating eaDir_tmp locally. Cleanup after generation is relevant only after SynologyDrive syncs. Just make sure the file types are supported and that the environment variable THUMBGEN_ENABLE_FFMPEG is set correctly. Restarting the service isn’t necessary. Checking webm generation

If they're only working with webm files, they won’t get any output due to a recent change. If they wish to generate webm locally even though Synology ignores them, I can help re-enable webm. First, they should confirm that Python ran successfully and created the eaDir_tmp\filename\; plus, they should check a sample video path that’s not webm. It's also important to ensure ffmpeg is installed on the Windows PATH; otherwise, Windows extraction could fail. If extraction returns an image, ffmpeg isn't needed. Lastly, they need to run PowerShell with the right code page. Clarifying thumbnail generation

It's important to note that on Windows, thumbnails in Explorer operate independently, meaning that the contents of 'eaDir_tmp' won’t show up as Explorer thumbnails. The script generating them doesn't change native thumbnails. If they want .jpg files in the SynologyDrive local folder to show up, they should ensure write permissions for the path under the user’s profile. Also, in the find_files valid extensions list, images like .jpg or .png are skipped to save time. No service restart is needed, and if they ran Option 2, it won't generate anything; they should use Option 1 or 3. Summarizing generation commands

Let's put together a concise command summary for running the generation directly, including some light code formatting. However, since we're not using any tools right now, we can skip the status update.

Here are the key points:

• No NAS service restart is needed; Explorer thumbnails are generated locally by psthumbgen.py.
• Since you ran Option 2 (cleanup only), it won’t generate anything.
• Please run either Option 1 or 3 with the specified path and check outputs under eaDir_tmp\....
• Note that .webm files are skipped; if the folder only contains .webm, nothing will be created. Would you like me to re-enable that option?
• Ensure ffmpeg is installed, possibly via winget.
• If you see no output, run the Python command with --directory and check for expected log lines and warnings. Including commands for installation and attributes

We can suggest commands to help with installation and file attributes. For installing ffmpeg, I recommend using winget install FFmpeg.FFmpeg, which is safer than other packages like Gyan.FFmpeg.

For Option 3, the expected order is to seed first using extract_eadir_to_tmp.sh on NAS, then run local generation and cleanup. We should also check for OneDrive Files-On-Demand attributes to ensure files are local. If files have cloud placeholders, ensure they are pinned with attrib +P -U for OneDrive. As for Synology Drive, it might require different methods for managing placeholders, but if files are locally present, the generation should work.

---

• No NAS service restart is needed for local generation. Option 2 (SSH cleanup only) doesn’t create thumbnails locally.
• Run Option 1 or 3 in autoThumbs with your path so psthumbgen.py writes eaDir_tmp\<filename>\SYNOPHOTO_THUMB_*.jpg.

Checks:

• Folder mostly .webm? We intentionally disabled .webm per your request, so nothing will be generated. I can re‑enable if you want.
• Ensure ffmpeg is installed for video fallback:

winget install FFmpeg.FFmpeg

• You can run directly to see logs:

python psthumbgen.py --directory "C:\Users\Nathan\SynologyDrive\YouTube\Streams\MixerTwitch\2025"

Expected: new eaDir_tmp subfolders per file (non‑webm) with JPEGs.

Analyzing thumbnail issues

I need to respond to the user’s issue with Windows Explorer not displaying the latest thumbnails. They've already restarted DSM and the Synology Drive Client, and their thumbnails are stored in eaDir_tmp within the Synology Drive folder. The problem might be that Windows Explorer doesn’t read @eaDir thumbnails, and the Synology Drive Client may not automatically update from eaDir_tmp. They might need to rename that directory locally. First, they should run extract_eadir_to_tmp.sh on NAS. Examining thumbnail synchronization

To tackle the user's issue with missing thumbnails, I see the local script generates thumb files in eaDir_tmp, which need to be pushed back to NAS and renamed to @eaDir. It seems the nascleanup.sh script is supposed to handle this, but there was an error indicating that eaDir_tmp wasn't synced, possibly due to permissions or Synology Drive settings. I'll advise the user to check that Synology Drive is set to sync hidden/system directories like eaDir_tmp and @eaDir to resolve the issue. Investigating sync issues with Synology Drive

I'm contemplating why the Synology Drive might not be syncing hidden directories like @eaDir, especially since it should sync everything unless there are specific filters set. The user previously disabled on-demand sync, which could affect this too. Since the NAS shows no eaDir_tmp present, the changes didn't upload. To resolve this, I’ll suggest checking the Synology Drive settings to ensure hidden directories aren’t being excluded and perhaps modifying the script to write directly to @eaDir to guarantee that syncs happen. Understanding missing subdirectories

I'm trying to figure out why the find command suggests that eaDir_tmp isn't present. I realize that eaDir_tmp is generated under each file's directory, not inside @eaDir, so the paths are structured like

/eaDir_tmp/. However, the problem arises during the NAS renaming stage, where it looks for eaDir_tmp directly in specific folders. There might also be issues due to the Windows path including additional subfolders. This could explain why the find command reports that certain directories are missing eaDir_tmp, which makes sense if thumbnails haven't been generated yet. Addressing thumbnail issues and sync

It appears the user is struggling with Windows Explorer not displaying new thumbnails, likely because the Synology Drive hasn't synced eaDir_tmp to NAS. The earlier script issues need correcting. To resolve this, I’d recommend the following steps:

1. Verify local 'eaDir_tmp' contains JPEGs.
2. Run autoThumbs.bat Option 3 again to ensure the latest script is used and uploads new files.
3. If eaDir_tmp still isn’t syncing, use a PowerShell command to tar and copy the entire directory to NAS, followed by running nascleanup.sh.

These steps should help address their concerns without needing to restart any services.

---

• No service restart required. The issue is that eaDir_tmp didn’t reach the NAS, so there was nothing to rename to @eaDir.

Do this:

• Verify local output exists:

dir "C:\Users\Nathan\SynologyDrive\YouTube\Streams\MixerTwitch\2025\eaDir_tmp" -Recurse -Filter SYNOPHOTO_THUMB_*.jpg

• If it exists, run Option 3 again (it now uses the fixed nascleanup.sh that correctly renames). If you still see “eaDir_tmp: No such file or directory” on the NAS, Drive isn’t syncing the folder.

Bypass Drive (copy directly over SSH), then rename:

# copy local eaDir_tmp to NAS
tar -C "C:\Users\Nathan\SynologyDrive\YouTube\Streams\MixerTwitch\2025" -cf - eaDir_tmp | `
ssh Hydra 'tar -C "/volume1/Hydra/YouTube/Streams/MixerTwitch/2025" -xf -'

# run the rename + permissions on NAS
ssh Hydra '~/nascleanup.sh "/volume1/Hydra/YouTube/Streams/MixerTwitch/2025"'

Tip:

• Make sure most targets aren’t .webm (we disabled those).
• Pin files locally so Windows/Drive doesn’t defer them:

attrib +P -U /S /D "C:\Users\Nathan\SynologyDrive\YouTube\Streams\MixerTwitch\2025\*"
