OvenMediaEngine (OME) is an Open-Source Streaming Server with Sub-Second Latency. It receives a video/audio source from encoders and cameras such as OvenStreamEncoder, OBS, or XSplit to WebRTC, RTMP, SRT, MPEG-2 TS, or RTSP. Then, OME transmits it using WebRTC, Low Latency DASH (LL-DASH), MPEG-DASH, and HLS.



OvenMediaEngine is AirenSoft's Open-Source and Sub-Second Streaming Project.

Input Protocols

OvenMediaEngine supports various input protocols such as

- Push: WebRTC, RTMP, SRT, MPEG-2 TS

- Pull: RTSP

Output Protocols

OvenMediaEngine provides multiple output protocols such as

- Sub-Second Latency: WebRTC

- Low Latency: Low Latency DASH (Chunked CMAF)

- Legacy: MPEG-DASH, HLS

Embedded Live Transcoder

OvenMediaEngine has embedded a Live Transcoder that supports VP8, H264, Opus, AAC, and Pass-Through.

Support for Sub-Second Latency

OvenMediaEngine supports smoother sub-second latency.
- WebRTC over TCP with Embedded TURN Server
- ICE (Interactive Connectivity Establishment)
- DTLS (Datagram Transport Layer Security)
- SRTP (Secure Real-time Transport Protocol)

Forward Error Correction

OME applies FECs to minimize packet loss.

- ULPFEC (Forward Error Correction) with VP8, H.264

- In-band FEC (Forward Error Correction) with Opus

Embedded WebRTC Signaling Server

OvenMediaEngine includes a WebRTC Signaling Server based on WebSocket.

Origin-Edge Structure

OvenMediaEngine has a structure that is easy to scale by applying Origin-Edge Clusters.


OvenMediaEngine provides features to help you build the monitoring you want and need.

Beta version features

Workflows of OvenMediaEngine


"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.

※ Please note that this benchmark was conducted in 2019 for reference only.
We will update the latest benchmark data as soon as possible.


Docker / Ubuntu 18+ / CentOS 7+ / Fedora 28+

We have prepared an easy installation and usage guide for OvenMediaEngine.

If you encounter any problems while testing OME, please feel free to email us.

And 'OvenSpace'

OvenSpace is an Open-Source and Web Video Conferencing Example. It is basically developed with OvenMediaEngine as a Streaming Server and OvenPlayer as an HTML5 Player.
