Not yet. We’re still early

I'm looking for one too.

Closest existing things are https://flare.pub + https://zap.stream + https://kinostr.com. But they are nothing like PeerTube. Also all of them seem to be closed source.

I'd be great to have something based on p2p-media-loader + nostr + blossom. But it shouldn't lock us on a single blossom server and shouldn't force us to update links to blossom servers in every single post we've made if we migrated to other blossom server(s). So I mean something different than this https://github.com/franzaps/n2m3u8#kind-1663-blossom-hls-playlists-draft

Similar to NIP-65, there could be a list of webtorrent trackers and blossom servers which could be preferably used for media lookups. And the nostr note could just store something like a magnet link.

Additionally, non-browser nostr clients could also do a real p2p with DHT (without webtorrent trackers and webrtc signaling servers).

Looks like something has appeared recently
