- We completely rewrote HLS following m3u8/ts spec, and HLS support h.264+aac/mp3.
- Highly efficient RTMP streaming, supporting 7k+ clients concurrency, vhost based, both origin and edge.
- Embedded simplified media HTTP server for HLS, api and HTTP flv/ts/mp3/aac streaming.
- Variety input: RTMP, pull by ingest file or stream(HTTP/RTMP/RTSP), push by stream caster RTSP/MPEGTS-over-UDP.
- Popular internet delivery: RTMP/HDS for flash, HLS for mobile(IOS/IPad/MAC/Android), HTTP flv/ts/mp3/aac streaming for user prefered.
- 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.
- Multiple feature: transcode, forward, ingest, http hooks, dvr, hls, rtsp, http streaming, http api, refer, log, bandwith test and srs-librtmp.
- 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.
- 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.
- MIT license, open source with product management and evolution.
Enjoy it!
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.
There are two types of people that have contributed to the SRS project:
- AUTHORS: Contribute important features. Names of all PRIMARY response in NetConnection.connect and metadata.
- CONTRIBUTORS: Submit patches, report bugs, add translations, help answer newbie questions, and generally make SRS that much better.
About all PRIMARY, AUTHORS and CONTRIBUTORS, read AUTHORS.txt.
A big THANK YOU goes to:
- All friends of SRS for big supports.
- Genes amd Mabbott for creating st(state-threads).
- Michael Talyanksy for introducing us to use st.
- Roman Arutyunyan for creating nginx-rtmp for SRS to refer to.
- Joyent for creating http-parser for http-api for SRS.
- Igor Sysoev for creating nginx for SRS to refer to.
- FFMPEG and libx264 group for SRS to use to transcode.
- Guido van Rossum for creating Python for api-server for SRS.

We use FMLE as encoder for benchmark. The latency of server is 0.1s+, and the bottleneck is the encoder. For more information, read bug #257.
About the HLS overhead of SRS, we compare the overhead to FLV by remux the HLS to FLV by ffmpeg.

The HLS overhead is calc by: (HLS - FLV) / FLV * 100%.
The overhead is larger than this benchmark(48kbps audio is best overhead), for we fix the #512.
SRS always use the most simple architecture to support complex transaction.
- System arch: the system structure and arch.
- Modularity arch: the main modularity of SRS.
- Stream arch: the stream dispatch arch of SRS.

Remark:
(1) Encoder: encoder must push RTMP stream to SRS server.
(2) MediaSource: any media source, which can be ingest by ffmpeg.
(3) Ingester: SRS will fork a process to run ffmpeg(or your application)
to ingest any input to rtmp, push to SRS. Read Ingest.
(4) Streamer: SRS will listen for some protocol and accept stream push
over some protocol and remux to rtmp to SRS. Read Streamer.
