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_user [request" '

'body_bytes_sent "$http_referer" '

'"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。
