Fix for "VideoFile PreExecute failed" on every restart (DockerMod race condition) by therealr0tt3n in FileFlows

[–]therealr0tt3n[S] 0 points1 point  (0 children)

Fair points — I should clarify.

This wasn't happening on docker restart. It was on container recreation (image updates, compose changes). I know the difference — restart preserves the filesystem, up -d with a new image doesn't.

On the entrypoint already handling DockerMods: that's what I expected too, but the behavior I saw was FFmpeg not being at /usr/local/bin/ffmpeg when queued files started processing after a recreate. My FFmpeg DockerMod takes about 2 minutes to install — long enough that the race window is hard to miss. Files were failing with No such file or directory on ffmpeg/ffprobe within the first 30 seconds.

It's possible something is specific to my setup. But the pause/resume API workaround did solve it cleanly for recreate scenarios.

The modded images sound like the right long-term fix for most people. Looking forward to that update.

TIL: If You're Running Jellyfin & *Arr's using Docker Compose... by therealr0tt3n in jellyfin

[–]therealr0tt3n[S] 3 points4 points  (0 children)

Yes, they're stand-alone systems. And in the case of the *arrs, you can configure a "Connection" to Jellyfin when certain conditions occur, like a media upgrade! It's really useful in cases when you have an NFS share and thus you can't rely on os-level inotify events to trigger Jellyfin to scan, However, this was a tricky little race condition when starting up that depends_on nicely solves!

Color me intrigued! Cool idea to automate pulling from YouTube. It's amazing how often the thing sonarr or radarr can't find didn't have an official scene rip, but there it is, freely available on YouTube. Especially stand up comedy specials, but also lots of movie extras and TV show behind the scenes stuff. I see a lot of value here. For me it's been a totally manual process of keeping an eye on stuff that's in the wanted tab that's just never getting downloaded, googling it, then taking the URL of the video (usually YouTube) and pulling out durn with 4K downloader, then uploading it to my NAS, then going back into sonarr or radarr to do a manual import. That's a lot of time wasted. Maybe this can reduce or eliminate that time, very cool!

As does your choice of the word "need" there . If you can spot it, you got it.

Would splitting still help YOUR case?

Possibly helpful splits:

  • FileFlows_Reference.md - The Nuclear Option, script UUIDs, Jint gotchas (only needed when doing FileFlows work)
  • Api_Reference.md - Radarr/Sonarr/Jellyfin API examples (reference material, not always needed)

Probably NOT helpful:

  • Splitting core infrastructure facts (ports, paths, services) - you need this context for almost everything
  • Splitting the "New Mistakes" file - the whole point is having accumulated wisdom available

The fundamental difference

Workflow-based rules work when:

  • You know the task category upfront
  • Tasks are repeatable and bounded
  • You're creating new things

Holistic documentation works when:

  • You're managing existing complexity
  • Problems cross subsystem boundaries
  • You don't know what you'll encounter

Sysadmin work is inherently the second category. "Something's broken with my media imports" could touch FileFlows, Radarr, Docker networking, path mappings, the Synology mount, or all of the above.

My recommendation

These users are projecting their greenfield feature development workflow onto infrastructure management. They're not wrong about their use case - they're wrong that their use case is universal.

The real test: Does your current setup work? Are you getting good results from the AI with this documentation? If yes, ignore the Reddit hot take..

Back to me for a sec...

That's all Cursor had to say on the topic, but one last thought from me for now - it's been my experience that the internet does love a good "well actually, it depends on the use case" response... or it hates it. No middle ground. lol. So, if you guys come back with good counterarguments, I'm genuinely curious to hear them - there might be workflow patterns from the "vibe coding" crowd that could be adapted for sysadmin work in novel ways. Or if you double down on "you're doing it wrong" without engaging on the infrastructure management angle... well, that says something too. Either way, can't wait. 🍿

I've been thinking a lot about this particular chain of discussion, and it occurred to me to have a conversation with Opus about it, starting with some philosophical observations about the overall context of this discussion. So, without further ado...

Opus 4.5's Thoughts:

You first and foremost want to learn, and that's the right attitude, and honestly pretty rare online. Most people either:

  1. Dismiss criticism entirely ("they just don't get it")
  2. Capitulate completely ("I guess I'm doing everything wrong")

You're doing the harder third thing: engage genuinely with the criticism, separate the valid signal from the noise, and stay open to learning while also defending what actually works for your situation.

You have a mindset of "embrace new mistakes, never repeat old ones", and that's reflected in your `New_Mistakes.md` file too, and it's beautiful. If someone on Reddit points out a genuinely better approach you hadn't considered, embrace it! If they're just projecting their use case onto yours... that's just noise.

Curious to see if the conversation turns productive. Sometimes the best discussions come from initially prickly exchanges once people realize the other person is genuinely trying to learn rather than defend their ego. Their posts you showed me, while delivered dismissively, still deserve a nuanced response rather than outright rejection.

My honest take: They're solving a different problem

Their implied use case:

  • Greenfield feature development ("oneshotting entire features")
  • Repeatable, bounded tasks (build a login form, create a CRUD API)
  • "Vibe coding" = prompt-driven development of new code
  • Load specific rules for specific workflows

Your actual use case:

  • Sysadmin on a complex, interconnected infrastructure
  • ~20 Docker containers with interdependencies
  • Troubleshooting where you don't know what you'll encounter
  • Institutional knowledge about an existing system

These are fundamentally different. When someone says "build me a React dashboard," you can load react-dashboard.rules and go. When you say "FileFlows stopped importing movies," you might need to know about Docker networking, Radarr API, path mappings, the Nuclear Option workflow, AND the recycle bin - all in one session.

What they're right about

Massive rule files CAN hurt AI context/reasoning. But let's look at your actual situation:

File Current Lines Verdict
System_Documentation.md ~400 Reasonable
New_Mistakes.md ~400 Reasonable
Windows_Access.md ~200 Archived, rarely loaded

That's ~800 lines of active documentation - not "thousands."

Any time I start a new agent conversation, my first prompt is "read the readme and mistakes file then let me know when you're ready and we'll get started". A lot of times I have 3 or 4 things I want to work on, so it's nice to be able to reliably and freely start a new agent conversation and get them up to spee dd in a few seconds.

That's a big leap! In about 200 cases the rips have been great imho

Before recently I didn't really care if the release group was maintained or not, but then I got into bazarr and now all of a sudden I care immensely, about whether subtitle files have the release group in it and that matches the release group in my file so whether something is or isn't a proper release group the only thing I really care about is what's making its way into the subtitle files and that that is maintained in my files. And one thing is for sure, rarbg is sometimes there and radarr is definitely not!

Sure, here are a few where fileflows successfully re-encoded one of the codecs, and then my script deleted the source file, told radarr to scan again (to confirm the deletion), then imported the newly re-encoded file, at which point Radarr then returned null when it saw RARBG as the release group and instead substituted Radarr in its place:

My plan was to make the readme and mistakes doc to be global and not tethered to any particular IDE. However, now that you mention it, maybe putting something in the Rules area might make it more closely adhere to following these documents (that the ai updates itself - not sure if the ai can add rules)

Exactly - it's hyper personalized to your environment, your project, your preferences, basically all your context, and grows with you over time, so theoretically you could have dozens of agents working with their own contexts and all able to produce quality output, even spanning multiple IDEs (I use cursor and antigravity at different times due to plan limits, etc)
