I want to use Low Latency Streaming on Wowza with my BYO CDN so I’ve just started setting up Wowza Streaming Engine referring this page “[Deliver Low-Latency HLS live streams using Wowza Streaming Engine](https://www.wowza.com/docs/deliver-apple-low-latency-hls-live-streams-using-wowza-streaming-engine)”.

My version is 4.8.17 on windows server 2019, and license is ‘One Month of Streaming’.

This page said this;

> [Configure a live application to deliver LL-HLS streams]  
> To connect to a CDN edge, such as the Fastly CDN, that can pull streams from the Wowza Streaming Engine origin application, use the **Live HTTP Origin** application type.

Howerver, on Live HTTP Origin Application, I could not see **‘Low-latency stream (ideal for chat applications)’** option which is shown on ‘Live Single Server or Origin’ Application.

Is there a configuration I need to enable it?  
I’ve already done the configuration changes (which are described in ‘Enable LL-HLS in Wowza Streaming Engine XML’ section)in Application.xml.

That option only affects RTMP and has nothing to do with LL-HLS. It just configures some buffers and intervals. The instructions from the article that you mentioned should be enough to use LL-HLS. Remember that LL-HLS requires SSL to be configured; so the prerequisite that is mentioned at the start of that article is imperative.

PS: @Rose_Power-Wowza_Com, it’s about time that this property is renamed or removed.
