A few days ago I spent a little bit of time looking at #PeerTube, to see if it can replace YouTube yet.
I tried and failed to set up an instance on my own server, because it doesn't have enough RAM to keep up with transcoding.
I made an account on cuddly.tube: @christianp@cuddly.tube, and had a go at live streaming there but I don't think it kept up. I also uploaded a short video: https://cuddly.tube/w/sMqkvBnzeLk1UtY44nXVeq.

Are there any PeerTube instances that can reliably live stream? I don't mind paying my way in.
