OvenMediaEngine (OME) is Open-Source Streaming Server with Sub-Second Latency. It receives RTMP from broadcasting tools such as OvenStreamEncoder, OBS, or XSplit, and transmits it using WebRTC, Low Latency HTTP (DASH), MPEG-DASH, and HLS. You can get Sub-Second Latency Streaming in your system.



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.

- 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

- File Recording

- RTMP Push Publishing (re-streaming)

- Thumbnail



- P2P Traffic Distribution (Only WebRTC)

Workflows of OvenMediaEngine


And if you want to see OvenMediaEngine's true potential on Android, use OvenStreamEncoder.

We have experienced less than ten frames of latency in an optimized environment.

※ OvenStreamEncoder is a Sample App based on OvenLikeKit for Android

If you want more features in OvenLiveEncoder, you need to purchase OvenLiveKit SDK.


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.
