Wow. The #foss #livestreaming scene is heating up! We have #PeerTube testing betas that should soon make livestreaming available to any instance that wants it, and at the same time we have #Owncast, which just got front page of #HackerNews, and 1000 stars on #GitHub in a single day.
Peertube is currently more like Youtube streaming, with load assistance from your viewers. Owncast is currently more polished with chat and a #Twitch style interface, but no load assistance I know of.
@Blort @fluxx it's written in python/flask and based on nginx-rtmp. It has a concept of edge nodes (dumb endpoints that are just cranking out http/hls) so it can scale somewhat large without much setup. We ran a conference on there with ~130 viewers at once. It can also restream to anything else that understands rtmp (basically every laelrge service).
