### Usage
2013-10-27 00:54:05 +00:00
step 1: build srs < br / >
< pre >
2013-11-04 15:23:13 +00:00
tar xf simple-rtmp-server-*.*.tar.gz
cd simple-rtmp-server-*.*/trunk
2013-11-30 03:59:21 +00:00
./configure --with-ssl --with-hls --with-ffmpeg
2013-10-27 00:57:16 +00:00
make
2013-11-25 16:07:43 +00:00
< / pre >
step 2: start srs < br / >
< pre >
2013-11-02 11:54:49 +00:00
./objs/simple_rtmp_server -c conf/srs.conf
2013-10-27 00:54:05 +00:00
< / pre >
2013-11-26 08:10:22 +00:00
