SRS is industrial-strength live streaming cluster, for the best conceptual integrity and the simplest implementation. SRS provides variety of inputs, for example, Push RTMP to SRS, Push RTSP/UDP/FLV to SRS, Pull Stream to SRS. SRS can transform the RTMP to other protocols or deliveries, for example, RTMP Transcode, Forward to Other Servers, Remux to HTTP-FLV, Remux to HLS, Remux to HDS, DVR to FLV. SRS canbe used in CDN for large stream clusters, for example, RTMP Cluster, VHOST, Reload, HTTP-FLV Cluster. Futhermore, SRS provides apis, for example, HTTP Callback, Security, HTTP API, RTMP Bandwidth Test. There're lots of Applications in both CDN and origin servers.

Get SRS from the downloads page of the project website. If you'd like to build SRS from scratch, visit Build SRS.

SRS runs on Linuxs, for instace, Centos and Ubuntu, and x86, x86-64, ARM and MIPS is ok. MacOS only supports code edit and build. SRS does not support other Unix-like system, neither windows. SRS build on the coroutine library state-threads, which simplify the complex protocol imlementations.

SRS is single process model, please use cluster to extend multiple CPUs.
