Usage

step 1: build srs 

tar xf simple-rtmp-server-*.*.tar.gz
cd simple-rtmp-server-*.*/trunk
./configure --with-ssl --with-hls
make

step 2: start srs 

./objs/simple_rtmp_server -c conf/srs.conf

step 3(optional): start nginx for HLS 

sudo ./objs/nginx/sbin/nginx

step 4: publish live stream 

FMS URL: rtmp://127.0.0.1:1935/live
Stream:  livestream
For example, use ffmpeg to publish:
    ffmpeg -re -i source.flv -vcodec copy -acodec copy \
    -f flv -y rtmp://127.0.0.1:1935/live/livestream

step 5: play live stream 

rtmp url: rtmp://127.0.0.1:1935/live/livestream
m3u8 url: http://127.0.0.1:80/live/livestream.m3u8

Summary

  1. simple: also stable enough.
  2. high-performance: single-thread, async socket, event/st-thread driven.
  3. support vhost, support __defaultVhost__.
  4. support both rtmp and hls(m3u8) live streaming.
  5. support reload config to enable changes.
  6. support cache last gop for flash player to fast startup.
  7. support listen at multiple ports.
  8. [dev] support forward publish stream to build active-standby cluster.
  9. [plan] support live stream transcoding by ffmpeg.
  10. [plan] support full http callback api.
  11. [plan] support network based cli and json result.
  12. [plan] support bandwidth test api and flash client.
  13. no edge server, origin server only.
  14. no vod streaming, live streaming only.
  15. no multiple processes, single process only.
