FFMPEG can used to transcode the live stream, output the other RTMP server. For detail, read FFMPEG.
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/trunkOr update the exists code:
git pullStep 2, build SRS. For detail, read Build
./configure --with-ffmpeg && makeStep 3, config file. For detail, read FFMPEG
Save the bellow as config file, or use conf/ffmpeg.transcode.conf instead:
# conf/ffmpeg.transcode.conf
listen 1935;
max_connections 1000;
vhost __defaultVhost__ {
transcode {
enabled on;
ffmpeg ./objs/ffmpeg/bin/ffmpeg;
engine ff {
enabled on;
vfilter {
}
vcodec libx264;
vbitrate 500;
vfps 25;
vwidth 768;
vheight 320;
vthreads 12;
vprofile main;
vpreset medium;
vparams {
}
acodec libfdk_aac;
abitrate 70;
asample_rate 44100;
achannels 2;
aparams {
}
output rtmp://127.0.0.1:[port]/[app]?vhost=[vhost]/[stream]_[engine];
}
}
}Step 4, start SRS. For detail, read FFMPEG
./objs/srs -c conf/ffmpeg.confStep 5, start encoder. For detail, read FFMPEG
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; \
doneOr use FMLE to publish:
FMS URL: rtmp://192.168.1.170/live
Stream: livestreamThe stream in SRS:
- Stream publish by encoder: rtmp://192.168.1.170:1935/live/livestream
- Play the original stream: rtmp://192.168.1.170:1935/live/livestream
- Play the transcoded stream: rtmp://192.168.1.170:1935/live/livestream_ff
Step 6, play the stream. For detail, read FFMPEG
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.
Step 7, play the transcoded stream. For detail, read FFMPEG
RTMP url is: rtmp://192.168.1.170:1935/live/livestream_ff
User can use vlc to play the RTMP stream.
Or, use online SRS player: srs-player-ff
Note: Please replace all ip 192.168.1.170 to your server ip.
