srs(simple rtmp origin live server) over state-threads.
srs is a simple, high-performance, running in single process, origin live server.
srs supports rtmp, HLS, transcoding, forward, http hooks.

step 1: build srs

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

step 2: start srs

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

step 3(optimal): start srs listen at 19350 to forward to

./objs/simple_rtmp_server -c conf/srs.19350.conf 

step 4(optional): start nginx for HLS

sudo ./objs/nginx/sbin/nginx 

step 5(optional): start http hooks for srs callback

python ./research/api-server/server.py 8085 

step 6: publish live stream

FMS URL: rtmp://127.0.0.1:1935/live Stream: livestream For example, use ffmpeg to publish: for((;;)); do \ ./objs/ffmpeg/bin/ffmpeg -re -i ./doc/source.200kbps.768x320.flv \ -vcodec copy -acodec copy \ -f flv -y rtmp://127.0.0.1:1935/live/livestream; \ sleep 1; \ done 

step 7: add server ip to client hosts as demo.

# edit the following file: # linux: /etc/hosts # windows: C:\Windows\System32\drivers\etc\hosts # where server ip is 192.168.2.111 192.168.2.111 demo 

step 8: play live stream.

rtmp url: rtmp://demo:1935/live/livestream m3u8 url: http://demo:80/live/livestream.m3u8 for android: http://demo:80/live/livestream.html 

step 9: play live stream auto transcoded

rtmp url: rtmp://demo:1935/live/livestream_ld m3u8 url: http://demo:80/live/livestream_ld.m3u8 for android: http://demo:80/live/livestream_ld.html rtmp url: rtmp://demo:1935/live/livestream_sd m3u8 url: http://demo:80/live/livestream_sd.m3u8 for android: http://demo:80/live/livestream_sd.html 

step 10: play live stream auto forwarded, the hls dir change to /forward

rtmp url: rtmp://demo:19350/live/livestream m3u8 url: http://demo:80/forward/live/livestream.m3u8 for android: http://demo:80/forward/live/livestream.html rtmp url: rtmp://demo:19350/live/livestream_ld m3u8 url: http://demo:80/forward/live/livestream_ld.m3u8 for android: http://demo:80/forward/live/livestream_ld.html rtmp url: rtmp://demo:19350/live/livestream_sd m3u8 url: http://demo:80/forward/live/livestream_sd.m3u8 for android: http://demo:80/forward/live/livestream_sd.html
