  • Interesting read about the Development Bystander Problem. I was indeed part of it. Maybe it is time to start contributing :)

    • He forgot some of the biggest reasons.

      • A larger codebase is generally just harder to work on. A more established product with more users tends to be larger.
      • More popular projects with many users tend to have developers that don't welcome new contributions. The investment required for a new developer to make an initial contribution is huge. Things like setting up the development environment and the stack of technologies and understanding the basic architecture are significant barriers to entry. Existing developers tend to not care about reducing that burden. After all, everyone who's *actually *contributing to the project is already over that barrier, right?

      Developers, open source or otherwise, should generally be excited about people "taking their jobs". Because you're going to have churn of developers over time, and if you're not bringing in fresh blood, then your project is eventually going to die. Do you really want to maintain every project you work on for the rest of your life? Encourage new blood. Do what you can to accept new ideas and directions unless you have very good and explicit reasons not to. If someone has a sightly different vision and is willing to hop that initial barrier and is willing to put in more work than you, don't undervalue that. Be willing to compromise a little to bring in a new developer. Sometimes you have to say no, but consider that you're saying no to a person who wants to volunteer their time to do work for you.

      On the other hand, there are tons of people who say they're eager to work on your project. You invest a little time into them, they provide nothing, and then vanish. It's easy to get jaded when you keep running into people who are more words than action. Be very careful what you promise you'll do, and if someone invests their time to help you, try to actually do what you said you would.

      • In some cases, PRs that have no merge conflicts can sit and languish for months on end. Example: https://github.com/jellyfin/jellyfin/pull/8914. I'm not suggesting cavalierly accepting all PRs, but the devs could do a better job of communicating with prospective contributors. My desire to contribute to Jellyfin was somewhat dampened by that initial experience.

        Edit: To be more constructive, I'd recommend not just a call to action (the blog post), but explicitly reaching out to devs who submitted their first PRs within the past year and finding out what their experiences were. Discovering a leaky onboarding process that you lose potential devs through could be instrumental!

      • A year or so ago I actually tried to get into Jellyfin and it wasn't really that pleasant experience.

        A bit of background: I am mainly a Java and JavaScript developer and have used Plex for over a decade now. I even developed a Plugin for Plex with Python. Naturally, Jellyfin came across my radar so I checked it out but they didn't have a Metadata Provider for the Metadata Source that I needed for some of my Libraries. There were alternatives but this would require to completely change my libraries which I wasn't interested in.

        So, I set out to just do it myself. I did know some C# but was by far not as up-to-date as you could be but I didn't really care because I wanted to see how that project went and if I could get into it I could learn more about C# while doing it.

        However, while I could get the Plugin compiled and loaded into a Jellyfin instance and even get some metadata downloaded, I quickly hit brick walls. From what I could tell, there weren't even method comments for, you know, methods you need to implement so that you can write a metadata provider.

        Not being able to resolve this through trial and error or looking at other currently active Providers (who seem to all do things differently, so no consistency) I asked on the Jellyfin Subreddit for help and got told to use the Matrix Chat instead. This was already annoying because that isn't how you amass knowledge that someone can fall back to and find when they have questions because Matrix is a walled garden. Regardless I asked there as well and didn't get any help or the responses didn't really help me.

        So, I shelved the project.

        What I want to say here is that FOSS Projects like Jellyfin should prioritize their documentation. The easier it is for people to understand how things work and "get into" the project the more people would be willing to actively contribute. I know that what I described above could just be my inexperience or lack of understanding and knowledge of C# and everything around it but I would imagine that many developers are in the same situation as me and would like to contribute but can't get over those hurdles. This is even worse for new developers who might want to stretch their legs in the Open Source community but are still learning.

        Reading this with "we need developers" and "you can contribute to our documentation" looks a bit contradictory to me because shouldn't the "experienced" contributor not create the documentation?

      • Spot on, I've seen plenty of great looking projects that I could contribute to but have next to no onboarding or set-up process. I'm keen on helping out but I'm not going to spend days setting things up locally because the primary project managers CBF to simplify the process.

        Minimizing the mental overhead to get started should be something these larger projects strive for, especially if they're struggling to get devs.

        Even something like having a docker container for web apps is massively helpful, being able to up a container and everything just works means more tech adjacent contributors can join the project (designers, UI/UX experts, testers etc)

        I've tried to set up the Jellyfin server project locally several times, but couldn't get dependency resolution working on my machine. I assume this is because I use Linux Mint rather than Windows, but I wasted multiple entire weekends trying to get it working to no avail. I'm a senior dev with professional experience in Java, Javascript, Python and Scala, so it's not like I've never done this sort of thing before. This particular setup just happened to turn into a nightmare.

      • Both of those points were actually covered in an earlier blogpost that was linked in this one. It talked about how the new contributors often have an incentive to make a quick easy fix to solve their problem while the established developers have a bunch of rules, often unspoken, that they use to try to keep the code base maintainable. If you just take in any old code, you run the risk of making the code harder to work with or alienating your developers who spend time cleaning up the code. If you dump a bunch of rules on the new contributor, you run the risk of making them feel unappreciated with your "nitpicky" feedback.

  • They definitely are in need of developers, there's an open ticket for memory leak issues and I just checked last week with the latest Master branch and it still exists at least on my system. Even if you just start the server and then never interact with it in any way whatsoever never load the interface play anything the memory just slowly grows and grows and grows until the system runs out of memory.

    It also still has a lot of pretty basic media matching errors where it will pick the wrong show for files for some reason or just fail to find the show at all. I've seen lots of cases where the only way to match an anime is to use the Japanese name in the search even though that brings up the English name metadata and other Oddities like that. All of my stuff is organized and named by sonar using a very clean format that should be very friendly to finding metadata

    i actually know a number of developers that are interested in jelly fin as a concept but when I ask if they are going to contribute they just go "eww no it's c# and .net i ain't touching that". Perhaps the developers should consider a rust rewrite lol, get the rust hype devs.

    • I'm been wanting to ask for a while, and now seems like a good time.

      Why do some programmers hate C# so much? What are the reasons for "eww no it's c# and .net i ain't touching that?"

  • Let me start with saying that I love jellyfin and I cannot recommend it enough

    Edit: just now watching a TV show over Chromecast. While.its streaming, I press back on the mobile.phone from which I'm casting. I go from the remote to the episode information and while the show continues to play audio, the video is replaced with information about the show. I go back to the show on my mobile, bit the video doesn't come back. So I stopmyhe show to restart, now the app hangs. Restart the app but now the app only shows the login screen and it refuses to connect or login.. Sigh. I still see the show info on the tv, still, turning tv off and on doesn't help. I gotta go unplug the tv, wait for the tv to boot back up, now I can login again and continue watching. This cost me ten minutes of cursing and really makes me feel like the mobile app isn't really tested very much, if at all. I know I'm complaining about free open source software but still. If it wants to be better than, say, Plex, then it MUST do better. I'd happily pay for this, that is not the problem, I want jellyfin, I want it to succeed, but jellyfin is making it really hard to enjoy the product.

    Having said that: yes, please work on bug fixing. There are some hair pulling annoying bugs in the system as it currently exists.

    Shows and movies get misidentified. This isn't a biggie in itself as it's fairly easy to just identify a shoe manually, but when I select the right show or movie, the submit should be instant and updates should be done in the background. Currently the update process takes anywhere from 30 seconds to various minutes while the web page just hangs. A lot of times it just completely stalls.

    Then scrubbing... it's gotten better, I suppose, but clicking the timeline is still risky business.

    Then subtitles. Half the time when switching from one movie to another, the frozen subtitles from the previous one are still there and the subtitles of the new movie are displayed above. If you do this a few times, the screen is full with frozen subtitles, yay

    Then mobile.. the mobile.app is halfway usable. Has all the problems described above but with more instability. Loads of times, while I'm watching a movie, suddenly I get the login screen because... reasons? If there is a disconnect for a second, TRY AGAIN MAYBE?

    Then using casting (using Chromecast) is barely usable. Once it works, it works and you can watch a movie, but lots of times, it can take 15 tries and 30 minutes to get a $+@(& movie to start casting correctly. If the cast program hangs on the tv, I have to unplug the TV which is very frustrating. DO NOT try to scrub using mobile. If you do that God knows where it'll send you, and half the time it'll hang, you have to restart the app,aubr even your TV. If you were halfway through a movie, well though luck, better start from the beginning because scrubbing to a certain point in time in a movie while casting is just plain not functional.

    Then the biggest gripe of all. And this is something I see everywhere, even on Netflix.... why is it so goddamned hard to remember what I was watching? If I binge watch a series and I go from S3E20 to halfway S4E2, then the next day jellyfin very helpfully tells me I was on S3E20. I then select S4E2 and want to resume halfway, where I left off, but jellyfin helpfully starts at the beginning. This is just an example, reality is worse. Again, Netflix had this too though less severe.

    Again, don't get me wrong. I'm VERY happy that jellyfin exists coz if it didn't I'd start writing my own. I'm very happy to not have tondo that, but I do have to say that there are VERY many bugs that make using jellyfin stressful at best, and impose at worst, and most of these bugs should not be that hard to fix.

    I really hope they'll focus on stability of the mobile app and casting for a while to at least make everything functional.
