Red5 Pro Version 5.2.0

Fall is here in New England. The leaves are changing colors and will soon be falling from the trees. In this spirit, we decided that now would be a good time to drop a new release.

Introducing Red5 Pro V 5.2.0!

Get more streams per server with WebRTC optimizations. Just take a look at our new benchmarks and you'll see that we added an extra 100 connections! Of course, slimming down WebRTC also means even lower latency.

Also, we added a much-requested feature: scheduling. Instead of having to manually spin up the necessary server instances, you can schedule them to deploy automatically at a certain time. Great news for HQ Trivia style apps, live auctions, or anything else with planned events.

That's just the beginning. See below for more details.
