The SRS realtime(low latency) mode can decrease the latency to 0.8-3s. For detail about latency, read LowLatency.
Suppose the server ip is 192.168.1.170
Step 1, get SRS. For detail, read GIT
git clone https://github.com/ossrs/srs
cd srs/trunk
Or update the exists code:
git pull
Step 2, build SRS. For detail, read Build
./configure && make
Step 3, config srs. For detail, read LowLatency
Save bellow as config, or use conf/realtime.conf
:
# conf/realtime.conf
listen 1935;
max_connections 1000;
vhost __defaultVhost__ {
tcp_nodelay on;
min_latency on;
play {
gop_cache off;
queue_length 10;
mw_latency 100;
}
publish {
mr off;
}
}
Step 4, start srs. For detail, read LowLatency
./objs/srs -c conf/realtime.conf
Step 5, start encoder. For detail, read LowLatency
Use FFMPEG to publish stream:
for((;;)); do \
./objs/ffmpeg/bin/ffmpeg -re -i ./doc/source.200kbps.768x320.flv \
-vcodec copy -acodec copy \
-f flv -y rtmp://192.168.1.170/live/livestream; \
sleep 1; \
done
Or use FMLE to publish:
FMS URL: rtmp://192.168.1.170/live
Stream: livestream
Note: To measure the latency, can use the clock of mobile phone.
Step 5, play RTMP. For detail, read LowLatency
RTMP url is: rtmp://192.168.1.170:1935/live/livestream
User can use vlc to play the RTMP stream.
Or, use online SRS player: srs-player
Note: Please replace all ip 192.168.1.170 to your server ip.
