Getting started with nginx rtmp
Build Utilities
sudo apt-get install build-essential libpcre3 libpcre3-dev libssl-dev git zlib1g-dev -y
On Amazon Linux: sudo yum install git gcc make pcre-devel openssl-devel zlib1g-dev
Make and CD to build directory (home)
sudo mkdir ~/build && cd ~/build
Download & unpack latest nginx-rtmp (you can also use http)
sudo git clone git://github.com/arut/nginx-rtmp-module.git
Download & unpack nginx (you can also use svn)
sudo wget http://nginx.org/download/nginx-1.14.2.tar.gz
sudo tar xzf nginx-1.14.2.tar.gz
cd nginx-1.14.2
Build nginx with nginx-rtmp
sudo ./configure --with-http_ssl_module --add-module=../nginx-rtmp-module
sudo make
sudo make install
Start nginx Server
sudo /usr/local/nginx/sbin/nginx
To set up RTMP support you need to add rtmp{}
section to nginx.conf
(can be found in PREFIX/conf/nginx.conf). Stock nginx.conf
contains only http{}
section.
sudo nano /usr/local/nginx/conf/nginx.conf
Use this nginx.conf
instead of stock config:
#user nobody;
worker_processes 1;
error_log logs/error.log debug;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
sendfile on;
keepalive_timeout 65;
server {
listen 8080;
server_name localhost;
# sample handlers
#location /on_play {
# if ($arg_pageUrl ~* localhost) {
# return 201;
# }
# return 202;
#}
#location /on_publish {
# return 201;
#}
#location /vod {
# alias /var/myvideos;
#}
# rtmp stat
location /stat {
rtmp_stat all;
rtmp_stat_stylesheet stat.xsl;
}
location /stat.xsl {
# you can move stat.xsl to a different location
root /usr/build/nginx-rtmp-module;
}
# rtmp control
location /control {
rtmp_control all;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
}
}
rtmp {
server {
listen 1935;
ping 30s;
notify_method get;
application myapp {
live on;
# sample play/publish handlers
#on_play http://localhost:8080/on_play;
#on_publish http://localhost:8080/on_publish;
# sample recorder
#recorder rec1 {
# record all;
# record_interval 30s;
# record_path /tmp;
# record_unique on;
#}
# sample HLS
#hls on;
#hls_path /tmp/hls;
#hls_sync 100ms;
}
# Video on demand
#application vod {
# play /var/Videos;
#}
# Video on demand over HTTP
#application vod_http {
# play http://localhost:8080/vod/;
#}
}
}
Restart nginx with:
sudo /usr/local/nginx/sbin/nginx -s stop
sudo /usr/local/nginx/sbin/nginx
Navigate your browser to http://localhost:8080/stat
to see current
streaming statistics, connected clients, bandwidth etc.
The easiest way to publish live video stream is using ffmpeg (or avconv). It's already installed on most systems and easy to install on others.
RTMP supports only a limited number of codecs. The most popular RTMP video codecs are H264, Sorenson-H263 (aka flv) and audio codecs AAC, MP3, Nellymoser, Speex. If your video is encoded with these codecs (the most common pair is H264/AAC) then you do not need any conversion. Otherwise you need to convert video to one of supported codecs.
We'll stream test file /var/videos/test.mp4
to server with ffmpeg.
Streaming without conversion (given test.mp4
codecs are compatible with RTMP)
ffmpeg -re -i /var/Videos/test.mp4 -c copy -f flv rtmp://localhost/myapp/mystream
Streaming and encoding audio (AAC) and video (H264), need libx264
and libfaac
ffmpeg -re -i /var/Videos/test.mp4 -c:v libx264 -c:a libfaac -ar 44100 -ac 1 -f flv rtmp://localhost/myapp/mystream
Streaming and encoding audio (MP3) and video (H264), need libx264
and libmp3lame
ffmpeg -re -i /var/Videos/test.mp4 -c:v libx264 -c:a libmp3lame -ar 44100 -ac 1 -f flv rtmp://localhost/myapp/mystream
Streaming and encoding audio (Nellymoser) and video (Sorenson H263)
ffmpeg -re -i /var/Videos/test.mp4 -c:v flv -c:a nellymoser -ar 44100 -ac 1 -f flv rtmp://localhost/myapp/mystream
ffmpeg -f video4linux2 -i /dev/video0 -c:v libx264 -an -f flv rtmp://localhost/myapp/mystream
ffmpeg -f avfoundation -framerate 30 -i "0" -c:v libx264 -an -f flv rtmp://localhost/myapp/mystream
ffplay rtmp://localhost/myapp/mystream
See test/rtmp-publisher
directory for test flash applets and html.
From OBS settings on the Stream tab change the type to Custom Streaming Server and the URL to rtmp://localhost/myapp and the steam key to your stream name like "mystream"
