Sub-Second Latency Live Streaming Server with Large-Scale and High-Definition

The latency of 30 seconds or more in a typical unidirectional broadcast is not an issue. However, this is 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 it yourself.

Various Protocols

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 need transcoding and it uses 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. This structure can easily replace the existing infra and operate reliably.

LLHLS and WebRTC Player

OvenPlayer is a very compact player based on HTML5 Standard. It also provides a web view optimized for the mobile environment. The main point is most optimized for OvenMediaEngine.

Ease of Use

OME and OvenPlayer provide a tutorial to help you install and use it efficiently. OME also supports platforms such as Docker, Ubuntu, CentOS, and Fedora.


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
