I can’t think of any PaaS, but for small group streaming there’s a number of software out there that has had this capability for a long time,l. I remember playing with Flash Media Server 10+ years ago that did exactly that.

However I’ve seen startups do mass scale live streaming at pretty low latency (8 - 16) seconds by just transcoding and serving clips off of S3
