Open-Source Sub-Second Latency Streaming Solution with LLHLS and WebRTC

The latency of 30 seconds or more in a typical unidirectional broadcast is not an issue. However, this s different for the interactive video streaming service because the viewer actively participates should be immediately reflected in the broadcast. The reasons for the latency in streaming is very diverse and difficult to solve. Now, OvenMediaEngine with our know-how can solve these problems at once.


OvenMediaEngine (OME) is an Open-Source Sub-Second Latency Streaming Server using LLHLS and WebRTC. OME supports you can create platforms/services/systems that live stream to large audiences of hundreds or more with sub-second latency and be scalable, depending on the number of concurrent viewers.


OvenPlayer is an Open-Source JavaScript-based LLHLS and WebRTC Player for OvenMediaEngine. OvenPlayer automatically plays with WebRTC, Low Latency HLS, MPEG-DASH, and RTMP for your browser environment. It also supports WebRTC Signaling from OME and includes various functions as the media player.



OME is transparent and reliable because it is open source. So you can use and edit it for free and get help from the community or customize this solution.

Sub-Second Latency

OME uses various protocols to support many streaming environments. They are WebRTC, Low Latency HLS (LLHLS), and MPEG-DASH.

Live Transcoder

OME has embedded Live Transcoder because browsers support a few codecs. So you can use VP8, H.264, Opus, AAC, and Pass-through.

Streaming Server

OME has the Origin-Edge structure that works by domain pattern matching to handle high-volume streaming and scaling.

HTML5 Player

OvenPlayer is most optimized player for OvenMediaEngine. It also provides a web-view for the mobile.

Ease of Use

OME supports various platforms to install and use it such as Docker, Ubuntu 18+, CentOS 7+, and Fedora 28+.

"How many concurrent users can OvenMediaEngine accommodate?"

We now provide a way to test and fine-tune the WebRTC performance of OvenMediaEngine for your environment and purpose. We used our testing tool, OvenRtcTester, to easily simulate a situation where we connected thousands of players to the OvenMediaEngine, and the results were stable.

Good-Software Level1 Certification

OvenMediaEngine has been tested for Functional suitability, Performance efficiency, Usability, Reliability, and Security by TTA based on international standards (ISO/IEC 25023, 25041, and 25051) and has been certified Good-Software Level 1.
