Using Nginx to build streaming media live platform

Source: Internet

All you have to say

The purpose of using Nginx to build streaming media platform is to support the RTMP protocol, which enables users to use RTMP (RTMP://192.168.201.128/MYAPP) protocol to push streaming to the server. The other user then requests the video stream information that the user pushes. Since it is the RTMP protocol, so you can use Adobe's Flashmedialiveencoder program, but also can be more professional streaming master software to complete the front-end live collection and coding. The individual is more like the use of streaming master, because this software is currently the most professional front-end coding system. To be honest, I'm actually a flash and flex developer, developing a variety of web video programs and video conferencing systems. The Java level is also very high. Welcome to face, I am such a person is not how humble, because I feel too humble hypocrisy. There are many streaming media servers around the world. There are commercial and open source, such as commonly used fms,red5,wowza.crtmpserver, and so on, if it is to do small video conferencing, I personally strongly recommend Red5. Red5 has a very open API, for the development of real-time requirements is relatively high convenience. Developers who develop tools and Java are also quick to get started.

Two environmental preparations

1 Prepare a Linux operating system, my Centos5. Windows is nignx to compile the module on its own, so I tested it on CentOS. My system information is as follows:

Linux localhost 2.6.18-128.el5 #1 SMP Wed 10:44:23 EST 2009 i686 Athlon i386 Gnu/linux

2 Preparing Packages

Nginx-1.4.7.tar.gz

Nginx-rtmp-module-1.1.7.tar.gz

Three Start installation

1 The dependency pack required to install the Nginx. Note that the dependencies of different systems or modules are not the same. I am here to install the most basic on the line.


[Root@localhost html]# yum install-y gcc gcc-c++

[Root@localhost html]# yum install–y openssl-devel pcre-devel

Note: It is best not to use the default Yum source. are uniformly replaced by Aliyun yum sources.

2 Unpack the bag first, it's no difficulty. Then execute the NINGX configuration file. After execution is done, compile, install


[Root@localhost local]# tar-zvxf nginx-1.4.7.tar.gz

[Root@localhost local]# wget https://github.com/arut/nginx-rtmp-module/archive/v1.1.7.tar.gz

[Root@localhost local]# Tar nginx-rtmp-module-1.1.7.tar.gz

[Root@localhost local]# TAR-ZXVF nginx-rtmp-module-1.1.7.tar.gz

[Root@localhost local]# cd/usr/local/nginx-1.4.7

./configure--prefix=/usr/local/nginx--add-module=/usr/local/nginx-rtmp-module-1.1.7

[Root@localhost nginx-1.4.7]# make && make install


Output log I'm not going to post it. After the compilation is complete. To modify the Nginx configuration file, let Nginx support the RTMP protocol.

3 After modifying the configuration file, the contents are as follows (change the configuration file can refer to):

[Root@localhost test]# pwd
/usr/local/nginx-rtmp-module-1.1.7/test


[Root@localhost test]# LL

For the convenience of me, I post my ngin profile completely:

}


Four boot servers, testing

1 perform Nginx/sbin/nginx start service. You should be able to see that the server also enables Port 1935, which means that Nginx has supported the rtmp push stream.

2 Copy all the files in your/usr/local/nginx-rtmp-module-1.1.7/test/www directory under Nginx HTML. This is the test case provided by the RTMP module. is a flash Client push stream and a playback stream case; it looks as follows:


[Root@localhost www]# cd/usr/local/nginx/html/

[Root@localhost html]# LL

Total 60

-rw-r--r--1 root root 537 Feb 5 18:54 50x.html

-rw-r--r--1 root root 15145 Feb 5 19:05 bg.jpg

-rw-r--r--1 root root 511 Feb 5 19:06 index.html

Drwxr-xr-x 2 root root 4096 Feb 5 19:05 Jwplayer

Drwxr-xr-x 2 root root 4096 Feb 5 19:05 Jwplayer_old

-rw-r--r--1 root root 1460 Feb 5 19:07 record.html


Five Tests,

1 Open Browser Enter address: http://192.168.201.128/record.html This is the test address for a push stream. Opening will prompt you to allow the use of your webcam. Let's do it. As follows


2 open another browser, enter http://192.168.201.128/index.html this test playback address effect is as follows:


Six summary.

You can use OBS to publish to Nginx. In general this approach is good, but if you want real-time high, multiplayer video is not very applicable.
