⁠Why SRS?

1. We completely rewrote HLS following m3u8/ts spec, and HLS support h.264+aac/mp3.
2. Highly efficient RTMP streaming, supporting 7k+ clients concurrency, vhost based, both origin and edge.
3. Embedded simplified media HTTP server for HLS, api and HTTP flv/ts/mp3/aac streaming.
4. Variety input: RTMP, pull by ingest file or stream(HTTP/RTMP/RTSP), push by stream caster RTSP/MPEGTS-over-UDP.
5. Popular internet delivery: RTMP/HDS for flash, HLS for mobile(IOS/IPad/MAC/Android), HTTP flv/ts/mp3/aac streaming for user prefered.
6. Enhanced DVR and hstrs: segment/session/append plan, customer path and HTTP callback. the hstrs(http stream trigger rtmp source) enable the http-flv stream standby util encoder start publish, similar to rtmp, which will trigger edge to fetch from origin.
7. Multiple feature: transcode, forward, ingest, http hooks, dvr, hls, rtsp, http streaming, http api, refer, log, bandwith test and srs-librtmp.
8. Best maintainess: simple arch over state-threads(coroutine), single thread, single process and for linux/osx platform, common server x86-64/i386/arm/mips cpus, rich comments, strictly follows RTMP/HLS/RTSP spec.
9. Easy to use: both English and Chinese wiki, typically config files in trunk/conf, traceable and session based log, linux service script and install script.
10. MIT license, open source with product management and evolution.

Enjoy it!

⁠About

SRS(Simple RTMP Server) over state-threads created on 2013.10.

SRS delivers rtmp/hls/http/hds live on x86/x64/arm/mips linux/osx, supports origin/edge/vhost and transcode/ingest and dvr/forward and http-api/http-callback/reload, introduces tracable session-oriented log, exports client srs-librtmp, with stream caster to push MPEGTS-over-UDP/RTSP to SRS, provides EN/CN wiki and the most simple architecture.
