This used to be an issue, but has been resolved in most major applications. Are you on an “app” version of slack? Try updating it, or try using an up to date webbrowser like Firefox, or anything based on Chromium if you prefer.

I’m going to assume you’re unable to see the embedded image. I didn’t add alt text, that’s my mistake.

Below “Besides”, there is a screenshot of a tweet by user @haydendevs stating “this is who you’re arguing with online” and an attached image of a series of dots connected by lines. This is the (overused) visual representation of a “neural network” in machine learning. The meaning of the image in this context is to state you are arguing with bots or AI online. I used this twitter screenshot as an attempt to make a joke of the fact the OP reads like AI-generated text.

I will edit the alt text in my comment above.

MPV is great, I use it all the time. It’s fully replaced VLC on my desktop.

It is not an “alternative to Jellyfin”. It does not offer many “comfort features” like (synced ootb) watch tracking. It does not transcode at all, and it doesn’t even run on devices that need transcoding most, like smart TVs.

These two applications fall into two different categories, and they will never replace each other. One is a media player, you throw mpv any video file, it puts it up on screen, great. The other is a media server, it allows you to sign in, browse your nicely organized library, and click play on the movie of your choice, very cool.

Even the idea of opening SMB or NFS to the entire internet just so your most technical of friends can manually download and watch a movie is insane compared to setting up Jellyfin. Reminder, not everyone has the connection to stream a full 4k bluray rip, transcoding allows those users to watch at all.
