Nginx rtmp HLS Live

Second, the installation of Nginx related modules

1. Environmental preparedness

Yum Install–y pcre Pcre-devel

Yum install–y zlib Zlib-devel

2. Download Nginx and rtmp module

wget http://nginx.org/download/nginx-1.6.2.tar.gz

Tar xzvf nginx_1.6.2.tar.gz

git clone git://github.com/arut/nginx-rtmp-module.git

3. Compiling nginx-rtmp

./configure--prefix=/usr/local/nginx--add-module=.. /nginx-rtmp-module--with-http_stub_status_module

Make

Make install

After the installation is complete, Nginx is located in the/usr/local/nginx/sbin directory, the configuration file nginx.conf in the/usr/local/nginx/conf directory

++++++++ test if Nginx is installed correctly +++++++++++

#cd/usr/local/nginx

#./sbin/nginx-c./conf/nginx.conf

Open the Web page http://localhost, if the display welcome means the installation is correct, if not shown, please check the Nginx log.

++++++++ Test rtmp+++++++++++

Modify the contents of the/usr/local/nginx/conf/nginx.conf as follows:

#debug
Daemon off;
Master_process off;

Error_log./error.log Debug;
events{
Worker_connections 1024;
}

rtmp{
server {
Listen 1935;
Chunk_size 4000;

#live
Application MyApp {
Live on;
}

}

Download an rtmp push flow tool from the Internet, I use the OBS (Open broadcaster Software), start pushing the stream rtmp://your_ip/myapp/test, using the player (http://www.cutv.com/demo/ LIVE_TEST.SWF) to see if it is OK.

++++++++ test HLS slicing function +++++++++++

Modify the contents of the/usr/local/nginx/conf/nginx.conf as follows:

#debug
Daemon off;
Master_process off;

Error_log./error.log Debug;
events{
Worker_connections 1024;
}

rtmp{
server {
Listen 1935;
Chunk_size 4000;

#live
Application MyApp {
Live on;

HLS on;
Hls_path/tmp/hls;
hls_fragment 2s;
Hls_playlist_length 6s;

}
}
}

#HTTP
http{
server {
Listen 80;

        #welcome
        location/{
            root   html;
            index  index.html index.htm;
       }

#hls
Location/hls {
Types {
APPLICATION/VND.APPLE.MPEGUSR m3u8;
VIDEO/MP2T ts;
}
root/tmp;
Add_header Cache-control No-cache;
}
}
}

Use the player on the VLC or ipad to view the http://yourip/hls/test.m3u8.

++++++++ testing ffmpeg transcoding function +++++++++++

Modify the contents of the/usr/local/nginx/conf/nginx.conf as follows:

#debug
Daemon off;
Master_process off;

Error_log./error.log Debug;
events{
Worker_connections 1024;
}

rtmp{
server {
Listen 1935;
Chunk_size 4000;

#live
Application MyApp {
Live on;

Exec/opt/ffmpeg/bin/ffmpeg-i rtmp://localhost/myapp/$name
-c:a copy-c:v libx264-b:v 512k-g 30-f flv rtmp://localhost/hls/$name _low;
}

Application HLS {

Live on;

HLS on;
Hls_path/tmp/hls;
Hls_nested on;
hls_fragment 2s;
Hls_playlist_length 6s;

Hls_variant _hi bandwidth=640000;

}
}
}

#HTTP
http{
server {
Listen 80;

        #welcome
        location/{
            root   html;
            index  index.html index.htm;
       }

#hls
Location/hls {
Types {
APPLICATION/VND.APPLE.MPEGUSR m3u8;
VIDEO/MP2T ts;
}
root/tmp;
Add_header Cache-control No-cache;
}
}
}

When using FFmpeg transcoding,

Exec/opt/ffmpeg/bin/ffmpeg-i rtmp://localhost/myapp/$name
-c:a copy-c:v libx264-b:v 512k-g 30-f flv rtmp://localhost/hls/$name _low;

Only transcoding the video, not processing the audio, while the stream from MyApp to HLS, Hls_variant will generate a multi-bitrate m3u8 file, while the tile file into the Test_low directory, access to multi-bitrate, direct access to Http://yourip/hls /test.m3u8, the corresponding bitstream is accessed based on the content implemented in this m3u8, in this case the actual stream URL is http://yourip/hls/test_low/index.m3u8
