How to have thumbnails for videos on an instance hosted using Yunohost?

[Terkyz]

Hello, I'm just starting into the world of selfhosting, and honestly I don't know pretty much at this moment, but I want to learn.

So, I started using Yunohost, but I really don't have a single idea how to enable thumbnails for videos, on mp4 and webm. I already have FFmpeg installed on Yunohost, but that's it, I haven't modified anything.

Thanks in advance and sorry if this is not the place to ask.

For that one, it might be better to directly ask the people on Yunohost.
