how to set AWS IVS Player to normal latency

Question

According to Amazon IVS doucumentation,

Chrome for iOS, Safari for iOS:
Ultra-low latency playback is not supported. Normal latency playback is supported.

So my streams' latency are around 2~5s,but Safari are always delay >15s. I'm using pure web player to stream:
<script src="https://player.live-video.net/1.14.0/amazon-ivs-player.min.js">

In my scenario, although latency is important, but the simultaneousness is much more crucial than latency.Is there any way to force all the platforms to delay >15s?

Answer 1

When creating a channel, you can choose NORMAL latency mode instead of LOW (source). Most third-party broadcasting software also has an option to introduce intentional delay, if that's what you're looking to do. Example for OBS here.

Edit: You can also turn live low latency off in the player (except on iOS). Docs.
