Usage

OvenMediaEngine uses WebRTC for sub-second latency streaming and Low Latency HLS for low-latency streaming depending on the system, network, and browser environment. If you use OvenMediaEngine and your environment cannot transmit low-latency streaming, it also supports general streaming using the legacy protocol as HTTP Live Streaming (HLS).
OvenMediaEngine can ingest media sources over WebRTC, SRT, RTMP, RTSP, and MPEG2-TS protocols through commonly used stream tools such as Open Broadcaster Software (OBS), Video camera, and Web browser with Webcam, encode them to Adaptive Bitrate Streaming (ABR) with the embedded live transcoder, and stream them to viewers over WebRTC and Low-Latency HLS. It is also possible to stream using legacy HLS for wider compatibility.
