So Twitch has a new “low latency” mode. Except by low latency they mean 2-3 seconds, whereas before it was more like 10 seconds. And for some reason they’re still using HLS. Meanwhile, Mixer has been sub-second for a long time… which is still an order of magnitude over ideal.

Why is it heavy? Is it an issue with the server software or something more fundamental?
It's basically mandatory DTLS, which requires negotiating a 1:1 stream with each client, so multicast doesn't work. The server-side software stacks are a lot less mature than the HTTP ecosystem. It's possible but not nice.

Sorry, DTLS for data, SRTP for media, but the key exchange is over DTLS either way.
Thanks. Twitter will use this to make your timeline better. UndoUndo

ah. of course, for Internet streaming where multicast isn’t possible and the alternative is HLS over regular TLS, that should make less difference…

still a whole lot of stack you essentially have to build and maintain yourself, because nobody's got ready-made solutions for it yet
