Release Camera Streamer Prusa Connect Uploader

[rizz360]

Hi! This is my first OctoPrint plugin submission.

Prusa Connect Uploader is a simple plugin that captures webcam snapshots from OctoPrint and uploads them to Prusa Connect, making it easier to monitor ongoing prints remotely through Prusa’s interface.

It allows users to:

• Set their Prusa Connect token
• Configure upload intervals
• Automatically upload snapshots to Prusa Connect

I've followed the plugin metadata format and included the required fields (including archive, python, cloud attribute, etc.). I hope I did everything correctly — feedback is more than welcome!

Thanks to the OctoPrint community for making plugin development so accessible 🙌

Your plugin should probably use more modern methods of getting the snapshot url here. Accessing this settings path is going to be deprecated in the future I think. You could use octoprint.webcam.get_default_webcam() I think, but would have to experiment a bit to validate.

What's the logic behind having the snapshots uploaded all the time versus just while printing?

Your threading timer here should also have the daemon set to true prior to starting, something like this.

    def start_upload_loop(self):
        interval = self._settings.get_int(["upload_interval"])
        self.timer = threading.Timer(interval, self.upload_loop)
        self.timer.daemon = True
        self.timer.start()

Finally, as mentioned in the code comment below about archive url, you should add a software update hook so your plugin can detect when and how to update. You can find more details here in the docs, and a quick example is provided there just make sure to replace updateplugindemo to prusa_connect_uploader in the return.

Hi @jneilliii , I’ve updated the plugin to:

• Use octoprint.webcams.get_default_webcam() and pull the snapshot URL from webcam.config.compat.snapshot (with a fallback to snapshotDisplay), replacing the deprecated settings path.

• Only run the upload loop during active prints by subscribing to PrintStarted, PrintDone, PrintCancelled, and PrintFailed events.

• Switch to octoprint.util.RepeatedTimer, which uses a daemon thread by default, so it won’t block shutdown.

• Add timeouts on HTTP requests and reuse the same timer instance for safety.

• Include a proper get_update_information() hook with the github_release format, and updated the registry metadata to point at refs/heads/main.zip so new installs always pull the latest code.

Thanks for your feedback—please let me know if anything else is needed!

Thanks for these changes, I only have one other change now before accepting this PR. Instead of self._logger.info at this line with every image upload, you should make that self._logger.debug to avoid spamming octoprint.log every 10 seconds by default.

Not really a deal breaker, but I'm also not seeing this implemented.

Also not seeing this implemented on the requests.

pull the snapshot URL from webcam.config.compat.snapshot

Hi everyone,

I recently spoke with foosel, the maintainer of OctoPrint, about the new webcam integration, and I thought it would be helpful to share what I learned — especially since I noticed you're running into the same issue I initially did.

It's not obvious at first (it certainly wasn't to me until it was explained), but the main purpose of the WebcamProviderPlugin mixin is to allow plugins to expose webcams that aren't associated with a direct URL.

Your plugin does work when using URLs from the Compatibility Layer (webcam.config.compat), but this approach prevents you from capturing snapshots from webcams that don’t provide a URL (i.e., when webcam.config.compat is None).

Going forward, keep in mind that the correct way to capture snapshots is to use the built-in take_webcam_snapshot method.

I assume that method also requires the knowledge of the configured webcam plugins and which one is active, so you'd have to iterate over get_webcam_configurations to find the active name.

Sorry about that! I quickly generated the reply using AI based on the git diff and it completely made that up.
I will change the self._logger.info to self._logger.debug in the coming days and will let you know when the new version is live.

Thanks, I'll look into that!

You should be aware that we now require plugin developers to tell us if they used any AI tool to code the plugin, and also added the following to the "Registering a new plugin" page:

Before registering your plugin, please consider whether you are actually willing and able to actively maintain it.

This means you will be around after registration too, keep up with changes in OctoPrint’s plugin API and adjust your plugin as necessary in new releases, fix bugs that are reported to you by the community, fix security issues reported to you and maybe also implement the one or other feature request.

You should not register a plugin just to make it easier for you to install it. We expect plugins on the official repository to be actively maintained. That doesn’t necessarily mean a lot of work, it very much depends on the complexity and size of your plugin. But you should be clear that publishing your plugin on the official repository means it becomes your responsibility – and, when you no longer can take care of it, notifying us and ideally also helping find someone else who can continue your work is also something you should consider your responsibility as a plugin maintainer.

This also means that you should be capable of fixing issues in your plugin even if your favourite genAI is down, and that you understand why your plugin works in the first place – meaning that completely vibe coded plugins are not something we will accept here.

tl;dr: By publishing a plugin on the official OctoPrint Plugin Repository, you become responsible of properly maintaining it. Be sure you are both willing and able to do this before you register your plugin.

Thanks for the heads up! In that case I'm retiring the pull request. The main motivation was for anyone that's interested to be able to easily install it.
