How does the p2p work? I thought there was a bittorrent-like aspect to it but what you're describing sounds different.
If multiple people are watching the same video, at the same resolution, it uses WebRTC (HLS P2P) to share data between them, saving bandwidth from the PeerTube instance.
A PeerTube instance can also function as a peer (seed) for another PeerTube instance.
Ah okay, this is what I was thinking of.
Sounds like Peertube admins can also proactively choose to mirror videos from other instances too?
Very nice. Would be cool to get some kind of massive user influx and see how well it does under load.
Yes. You can mirror videos from other instances. This also work as a kind of redundancy, if the PeerTube instance with the original video is down.
