Low Latency Livestreaming - Full Release

Overview

With this update, builders and viewers can expect drastically improved latency for browser-based applications, with a target range of 3-5s for transcoded renditions and sub-second for the source.

Details

To access this feature, builders must either:

Use the Livepeer Player
@livepeer/react@2.5.4
or later, and specify
lowLatency
as a prop
Use the lvpr.tv iframe, and specify
lowLatency=true
as a query parameter
Use another player that supports WHEP WebRTC playback, and ensure that it uses the WebRTC URL in lieu of the HLS playback URL

If you choose to use another player, we strongly recommend that you incorporate fallback logic, whereby the player reverts to HLS in cases where network conditions may not support WebRTC.

Limitations

WebRTC playback is not implemented in the Livepeer React Native player. This is tracked as follow-up work.

What's Next

In the future, we plan to enable low latency playback by default rather than as an opt-in feature
Building on the WebRTC infrastructure that enables these latency improvements, we will enable In-browser Broadcasting via Livepeer.js
We will add WebRTC playback to our React Native player.
