Streaming protocol support
Proprietary UMS streaming protocol is based on Microsoft DirectShow, and therefore, UMS protocol is codec-independent. UMS protocol realizes a distributed DirectShow graph where source filter resides on the server computer and renderer filter resides on the player computer; a corresponding DirectShow decoder needs to be installed at the player computer/device.
Supported file container formats: MP4, ASF, AVI, MKV, MPEG, WMV, FLV, Ogg, MP3, 3GP, MOV, other containers.
With regards to live video, Unreal Media Server acts as universal transmuxer: it receives live streams multiplexed (muxed) in different protocols/formats (WebRTC/RTSP-RTP, MS-WMSP/ASF, MPEG2-TS, UMS), demuxes (extracts) the actual elementary streams from these containers (no decoding or transcoding), and muxes (packages) it for specific player delivery. For example, it can ingest a live RTSP stream from IP camera and send it to WebRTC players; at the same time re-mux it into RTMP/FLV protocol/format for delivery to Adobe Flash Player; at the same time re-mux it to video/mp4 segments for delivery via WebSocket protocol to HTML5 MSE players in web browsers; at the same time re-mux it to MPEG2-TS for delivery to Set-Top box, and at the same time send it to iOS devices with HLS protocol. Unreal Media Server is known for low latency live streaming; with UMS, WebRTC, WebSocket-video/mp4, RTMP and MPEG2-TS protocols latencies of 0.2–2 seconds can be achieved when streaming over the Internet; with Apple HLS the latency can be as low as 3 seconds.
