Lemmy only supports images. You cannot upload video files to your instance. My workaround is to upload videos to YouTube or catbox.moe and then post the URL.
Lemmy instances are hosted on personal servers. They don't have the massive storage space and bandwidth that a billion dollar corporation has. If you want an instance that hosts videos, then make your own. You'll have to buy a lot of storage, and pay for a lot of bandwidth, though, because videos take up a lot of both of those things.
How everybody wins if leave? Why the toxicity? Because I criticized this platform? Because I'm not thinking like you? It's really easy to to be toxic when you don't see the other person ha?
The Liftoff developers can integrate APIs from video-hosting websites like catbox.moe and YouTube into their app. By doing so, we would be able to upload videos directly through the app without having to leave it. It would then automatically post the video URL on our behalf.
If you like the idea, feel free to make this suggestions to the devs.
