SRS Server - Experience Ultra-Low Latency Live Streaming with OBS WHIP!

· 3 min read

OBS now features WHIP support, with the patch having been recently merged. This enables various new functions and possibilities with OBS WHIP, as the latency drops from 1 second to 200 milliseconds.

Without OBS WHIP, you can employ RTMP+WebRTC for live streaming, which results in a latency of approximately 500ms. However, by using OBS WHIP, you can achieve low-latency live streaming with a latency of around 200ms.

Furthermore, even in situations with poor network connections or when streaming over the internet, OBS WHIP maintains a consistently low and stable latency.

In this tutorial, I will demonstrate how to effortlessly utilize OBS WHIP with SRS in just three simple steps.

The Oryx also supports OBS WHIP, enabling you to establish a WHIP service with just one click. Refer to Effortlessly Create a Public Internet WHIP Service for OBS.

Cloud Service and Support

I tested the TRTC cloud service and it works great with OBS WHIP. If you're looking for a WHIP cloud service that has 24/7 support, I definitely suggest trying TRTC. To see a demo, click here.

At SRS, our goal is to establish a non-profit, open-source community dedicated to creating an all-in-one, out-of-the-box, open-source video solution for live streaming and WebRTC online services.

Additionally, we offer a Cloud service for those who prefer to use cloud service instead of building from scratch. Our cloud service features global network acceleration, enhanced congestion control algorithms, client SDKs for all platforms, and some free quota.
