We've been hard at work on a number of features including WebRTC, improved APIs, performance/latency increases on the mobile SDK. Since my focus has been on the Red5 Pro API (which is going to support WebSockets in next week's release), I've been spending a ton of time on WebSockets. We were missing a lot of documentation on how to best use WebSockets with Red5 so we've added some more details for developers looking to take advantage of it.
Quite useful! Especially since this is a low-latency technique that can be used in conjunction with the very low-latency video streaming on Red5 Server. Here are few tips for using WebSockets on Red5.
