Nginx Build rtmp Video Streaming Server (Ubuntu 16.04)

1 Preparation
Install the dependency packages needed by nginx

• Install mercurial to support hg command

sudo add-apt-repository ppa:tortoisehg-ppa/releases
sudo add-apt-repository ppa:mercurial-ppa/releases
sudo apt-get update
sudo apt-get install mercurial python-nautilus tortoisehg

sudo apt install mercurial

• Solve the dependency package openssl installation

sudo apt-get install openssl libssl-dev

• Solve the installation of dependent package pcre

sudo apt-get install libpcre3 libpcre3-dev

• Resolve the dependency package zlib installation

sudo apt-get install zlib1g-dev

If the corresponding dependency package is not installed, nginx cannot be compiled normally

2 Compile Nginx
2.1 Nginx download

• Create rtmp in the user directory

mkdir ~/rtmp
cd ~/rtmp

Official website: http://nginx.org/

• Download nginx (need to install mercurial to support hg command)

hg clone http://hg.nginx.org/nginx

Download nginx-rtmp-module
Official website: nginx-rtmp-module

git clone https://github.com/arut/nginx-rtmp-module.git
at this time

lqf@ubuntu:~/rtmp$ ls

nginx nginx-rtmp-module

2.2 Compile
Enter the root directory of nginx source code:

cd nginx

Configuration

auto/configure --with-http_ssl_module --with-http_v2_module --with-http_flv_module --with-http_mp4_module --add-module=../nginx-rtmp-module

Compile and install

make -j4
sudo make install

Installed to /usr/local/nginx by default

Configuration file path: /usr/local/nginx/conf/nginx.conf

3 Configure nginx
3.1 On-demand configuration
In your configuration, you need to change the IP to your server IP or domain name.

3.1.1 Create Media Folder

/mnt/hgfs/dn_class/vod

3.1.2 Prepare media files:
Copy the media file 35.mp4 to the /mnt/hgfs/dn_class/vod directory.
The media files can be copied by themselves, in accordance with the AAC+H264 format.

3.1.3 Configure http in nginx
After the nginx server has been set up in the previous step, we can start a video-on-demand service. Open the configuration file nginx.conf (path /usr/local/nginx/conf/nginx.conf) and add the RTMP configuration.

#user nobody;
worker_processes 1;

#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;

#pid logs/nginx.pid;


events {
    worker_connections 1024;
}

rtmp {#RTMP server
    server {
        listen 1935; #server port
        chunk_size 4096; #chunk_size
        application vod {
            play /mnt/hgfs/dn_class/vod; #media file position
        }
    }
}
........
Don't care about other configurations

Modify the configuration file to support on-demand
The configuration directory /mnt/hgfs/qingfu/vod is the location for storing video files, so let's put a file in it. I put a 35.mp4 file.

After the file is placed, let us restart nginx

sudo /usr/local/nginx/sbin/nginx -s reload

If an error is reported

nginx: [error] open() "/usr/local/nginx/logs/nginx.pid" failed (2: No such file or directory)
It means that nginx is not started, so you need to start it first

sudo /usr/local/nginx/sbin/nginx

3.1.4 Play with ffplay on Windows
Note: The Ubuntu network connection installed on the virtual machine needs to select "Bridge Mode", so that windows and Ubuntu are IPs on the same network segment.
My current IP is: 192.168.100.33

ffplay rtmp://192.168.100.33/vod/35.mp4

It can be played under normal configuration. If it cannot play normally, you need to check whether the vod directory is correct.

3.2 Live broadcast configuration
Then we add the configuration of the live server on the basis of the on-demand server configuration file.

3.2.1 Configuration
Adding an application to the RTMP service can be named arbitrarily or multiple names. Since it is a live broadcast, I call it live. If you plan to make multiple sequences of live broadcasts, you can use live_cctv.

#user nobody;
worker_processes 1;

#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;

#pid logs/nginx.pid;


events {
    worker_connections 1024;
}

rtmp {#RTMP server
    server {
        listen 1935; #server port
        chunk_size 4096; #chunk_size
        # vod server
        application vod {
            play /mnt/hgfs/dn_class/vod; #media file position
        }
        # live server 1
    application live{ #Darren live first add
        live on;
    }
        # live server 2
    application live_cctv{ #Darren live add
        live on;
    }
    }
}
........
Don't care about other configurations

Comparison with original file after modification

3.2.2 Push Stream
Use ffmpeg to generate a simulated live source on Ubuntu and push it to the rtmp server

ffmpeg -re -i /mnt/hgfs/dn_class/vod/35.mp4 -c copy -f flv rtmp://192.168.100.33/live/35
or

ffmpeg -re -i /mnt/hgfs/dn_class/vod/35.mp4 -c copy -f flv rtmp://192.168.100.33/live_cctv/35
Note that the source file must be H.264+AAC encoded.

3.2.3 Pull flow
Use ffplay to pull streaming on the windows side

ffplay rtmp://192.168.100.33/live/35

Or (need to correspond to push streaming)

ffplay rtmp://192.168.100.33/live_cctv/35
