Use Nginx to build streaming media platform (this way does not apply to chat with many people)

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:// 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 the client can be a flash program, you can also OBS (Open broadcaster Software) This relatively popular live client. Individuals are more interested in using OBS, and frankly I am also 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 on the reincarnation surface. 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



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 zlib- 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- 
[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
[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

[Root@localhost test]# ll Total
-rwxrwxr-x 1 root  2015
1 root Roo T-  2015
-rw-rw-r--1 root 1245 Mar  2015 nginx.conf
-rwxrwxr-x 1 root root   Mar  2015
-rw-rw-r--1 root  499 Mar  2015
drwxrwxr-x 2 root R Oot 4096 Mar  2015 RTMP-PU

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

#user nobody;
Worker_processes 1;
#error_log Logs/error.log;
#error_log Logs/error.log Notice;
#error_log Logs/error.log Info;
#pid Logs/;
        Events {worker_connections 1024} rtmp {server {listen 1935;
            Application MyApp {live on;
            #record keyframes;
            #record_max_size 128K;
            #record_interval 30s;
            #on_publish Http://localhost:8080/publish;
            #on_play Http://localhost:8080/play;
        #on_record_done Http://localhost:8080/record_done;
    }}} http {include mime.types;
    Default_type Application/octet-stream;
    #access_log Logs/access.log Main;
    Sendfile on;
    #tcp_nopush on;
    #keepalive_timeout 0;
    Keepalive_timeout 65;
    #gzip on;
        server {Listen 80;
        server_name localhost; Location/{root HTml
        Index index.html index.htm;
        } #error_page 404/404.html;
        Error_page 502 503 504/50x.html;
        Location =/50x.html {root html;

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.

[Root@localhost conf]# netstat-antpl Active Internet connections (servers and established) Proto recv-q Send-q Local Addr                ESS Foreign Address State Pid/program name TCP 0 0          * LISTEN 11908/nginx TCP 0 0*                   LISTEN 2674/portmap TCP 0 0*      LISTEN 11908/nginx TCP 0 0* LISTEN 2965/CUPSD TCP 0 0* LISTEN 2989/sen      
Dmail:acce TCP 0 0* LISTEN 2703/rpc.statd   TCP 0 0 established 11950/nginx:worker TCP 0 1934 established 11950/nginx:worker TCP 0 0::: 22:: :* LISTEN 2950/sshd TCP 0 0:: ffff: ffff:192.168.  201.1:56019 established 12197/sshd:root@no TCP 0 592:: ffff: ffff: Established 3268/1

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
-rw-r--r--1 root root< c3/>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   51 1 Feb  5 19:06 index.html
drwxr-xr-x 2 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: 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 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.
