Nginx搭建RTMP视频点播/直播/HLS服务器

一、nginx的服务器的搭建

安装nginx的依赖库

sudo apt-get update 

sudo apt-get  install libpcre3 libpcre3-dev

sudo apt-get  install openssl libssl-dev

下载nginx

wget http://nginx.org/download/nginx-1.11.3.tar.gz

下载rtmp的module

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

然后分别解压缩,进入nginx目录

cd nginx-1.11.3

安装:

./configure--add-module=../nginx-rtmp-module

make

sudo make install

运行nginx

进入安装目录/usr/local/nginx，运行命令./sbin/nginx

打开浏览器在地址栏输入：localhost。如果，如下图显示那样就证明您的nginx服务器搭建成功了。

修改服务器的配置文件nginx.conf

cd /usr/local/nginx

vi conf/nginx.conf

我的内容大致是这样的:

#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 {

server {

listen 8082;

chunk_size 4000;

#HLS

# For HLS to work please create a directory in tmpfs (/tmp/app here)

# for the fragments. The directory contents is served via HTTP (see

# http{} section in config)

#

# Incoming stream must be in H264/AAC. For iPhones use baseline H264

# profile (see ffmpeg example).

# This example creates RTMP stream from movie ready for HLS:

#

# ffmpeg -loglevel verbose -re -i movie.avi  -vcodec libx264

#    -vprofile baseline -acodec libmp3lame -ar 44100 -ac 1

#    -f flv rtmp://localhost:1935/hls/movie

#

# If you need to transcode live stream use 'exec' feature.

#

application vod {

play /opt/video/vod ; #//file path

}

application live  {

live on;

hls on;

wait_key on;

hls_path /opt/video/hls;

hls_fragment 10s;

hls_playlist_length 60s;

hls_continuous on;

hls_cleanup on;

hls_nested on;

}

}

}

http {

include      mime.types;

default_type  application/octet-stream;

#log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '

#                  '$status $body_bytes_sent "$http_referer" '

#                  '"$http_user_agent" "$http_x_forwarded_for"';

#access_log  logs/access.log  main;

72,0-1        21%

#access_log  logs/access.log  main;

sendfile        on;

#tcp_nopush    on;

#keepalive_timeout  0;

keepalive_timeout  65;

#gzip  on;

server {

listen  8081;

location /stat {

# Serve HLS fragments

rtmp_stat all;

rtmp_stat_stylesheet stat.xsl ;

}

location /stat.xsl {

root /home/vert/nginx-rtmp-module/;

}

location /live  {

types {

application/vnd.apple.mpegurl m3u8;

video/mp2t ts;

}

alias  /opt/video/hls;

expires -1;

add_header Cache-Control no-cache;

}

location / {

root html;

index index.html index.htm;

}

error_page 500 502 503 504  /50x.html;

location = /50x.html {

root html;

}

}

server {

listen      8080;

server_name  localhost;

#charset koi8-r;

#access_log  logs/host.access.log  main;

location / {

root  html;

index  index.html index.htm;

}

#error_page  404              /404.html;

# redirect server error pages to the static page /50x.html

#error_page  404              /404.html;

# redirect server error pages to the static page /50x.html

#

error_page  500 502 503 504  /50x.html;

location = /50x.html {

root  html;

}

# proxy the PHP scripts to Apache listening on 127.0.0.1:80

#

#location ~ \.php$ {

#    proxy_pass  http://127.0.0.1;

#}

# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000

#

#location ~ \.php$ {

#    root          html;

#    fastcgi_pass  127.0.0.1:9000;

#    fastcgi_index  index.php;

#    fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;

#    include        fastcgi_params;

#}

# deny access to .htaccess files, if Apache's document root

# concurs with nginx's one

#

#location ~ /\.ht {

#    deny  all;

#}

}

# another virtual host using mix of IP-, name-, and port-based configuration

#

}

重启nginx

sudo ./sbin/nginx -s reload

查看配置是否生效，浏览器输入 http://localhost:8081/stat

如图代表启动成功

二、使用ffmpeg推流（录屏）

如果没有ffmpeg需要先自行安装ffmpeg

推流命令无音频

ffmpeg -f avfoundation -i "1"    -strict -2  -acodec aac -f flv rtmp://your ip:8082/live/test

推流带有音频

不使用h264:     ffmpeg -f avfoundation -i "1:0"  -strict -2  -acodec aac -ar 44100 -ac 1 -f flv  rtmp://ip:8082/live/test

使用h264:

ffmpeg -f  avfoundation -i "1:0"  -vcodec libx264 -preset veryfast -maxrate 3000k -bufsize 4000k -acodec libmp3lame  -ar 44100 -ac 1 -f flv  rtmp://ip:8082/live/test

如果移动设备解码的话使用:

ffmpeg -f  avfoundation -i "1:0"  -framerate 25 -vcodec libx264 -preset veryfast -maxrate 3000k -bufsize 4000k -acodec libmp3lame  -ar 44100 -ac 1 -f flv  rtmp://ip:8082/live/test

上面是MAC OS，下面是Ubuntu

./ffmpeg -f alsa -ac 2 -i pulse -f x11grab -r 30 -s 1024x768 -i :0.0 -framerate 25 -vcodec libx264 -preset veryfast -maxrate 3000k -bufsize 4000k -acodec libmp3lame  -ar 44100 -ac 1 -f flv  rtmp://ip:8082/live/test

./ffmpeg -f alsa -ac 2 -i pulse -f x11grab -r 30 -s 1024x768 -i :0.0 -framerate 25 -vcodec libx264 -preset veryfast -maxrate 3000k -bufsize 4000k -strict -2  -acodec aac  -f flv  rtmp://ip:8082/live/test

查看RTMP流:

这里测试还有VLC客户端进行打开:

拉流地址(VLC客户端打开）

rtmp://your ip:8082/live/test

不出意外就能查看到屏幕视频信息了，测试过程中推流占用带宽过大（由于我用的mace ffmpeag未带h264编码器)，后期需要进行视频压缩和音频压缩，同时我自己的服务器延迟比较大，后续有需要优化。
