ubuntu下nginx +海康摄像头搭建http-flv(rtmp)流媒体

本文链接：https://blog.youkuaiyun.com/aerbeisishan2008/article/details/134534956

一、环境搭建

1、依赖安装

sudo apt-get install gcc
sudo apt-get install libpcre3 libpcre3-dev
sudo apt-get install zlib1g zlib1g-dev
sudo apt-get install libssl-dev

2、ngnix下载及安装

wget https://nginx.org/download/nginx-1.22.0.tar.gz
tar -zxvf nginx-1.22.0.tar.gz

tar解压完成之后出现nginx-1.22.0，然后在同级目录下载rtmp模块

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

下载完成rtmp模块之后，进行安装，指定安装目录到/usr/local/nginx下

cd nginx-1.22.0
./configure --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module --with-http_mp4_module --add-module=../nginx-rtmp-module
make
sudo make install

由于nginx本身不支持http-flv，安装http模块，在浏览器即可调用，所以需要单独下载nginx-http-flv-module，重新进行编译，编译方式按照官网说明即可。https://github.com/winshining/nginx-http-flv-module

cd nginx-1.22.0
./configure --add-module=../nginx-http-flv-module-master
make
sudo make install

查看安装结果

lab@lab-System-Product-Name:/usr/local/nginx/sbin$ ./nginx -v
nginx version: nginx/1.22.1

3、ffmpeg安装

sudo apt install ffmpeg

以上命令直接安装，或者参考其他博客，如ubuntu安装ffmpeg_ubuntu下安装ffmpeg_Eanve的博客-优快云博客

二、配置nginx

1、切换到nginx.conf目录

cd /usr/local/nginx/conf/

2、编辑nginx.conf文件，如下：

user  root;
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;
}


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;

    sendfile        on;
    #tcp_nopush     on;

    #keepalive_timeout  0;
    keepalive_timeout        800;
    proxy_connect_timeout    800;
    proxy_read_timeout       800;
    proxy_send_timeout       800;
    client_max_body_size     5120m;
    #gzip  on;

    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   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }

        location /pop/video {
                alias /var/video;
        }

        location /stat {
                rtmp_stat all;
                rtmp_stat_stylesheet stat.xsl;
        }

        location /stat.xls {
                root html;
        }

        location /live {
                flv_live on;#打开HTTP播放FLV直播流功能
                chunked_transfer_encoding on;#支持'Transfer-Encoding: chunked'方式回复
                add_header 'Access-Control-Allow-Origin' '*';#添加额外的HTTP头
                add_header 'Access-Control-Allow-Credentials' 'true';#添加额外的HTTP头
        }
        location /hls {
            types {
                application/vnd.apple.mpegurl m3u8;
                video/mp2t ts;
            }

            root /tmp/hls;
            add_header 'Cache-Control' 'no-cache';
        }

        location /dash {
            root /tmp/dash;
            add_header 'Cache-Control' 'no-cache';
        }

        # 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;

        #}

        # 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
    #
    #server {
    #    listen       8000;
    #    listen       somename:8080;
    #    server_name  somename  alias  another.alias;

    #    location / {

    #    ssl_certificate_key  cert.key;

    #    ssl_session_cache    shared:SSL:1m;

}

rtmp_auto_push on;
rtmp_auto_push_reconnect 1s;
rtmp_socket_dir /tmp;

rtmp {
    out_queue           8192;    #数据传输块的大小--默认
    out_cork            8;
    max_streams         128;
    timeout             15s;
    drop_idle_publisher 15s;

    server {
        listen 1935;                    #服务端口--默认
        server_name rtmp;
        application haikang01 {
                live on;
                gop_cache on; #打开GOP缓存，减少首屏等待时间
        }

        application hls {
            live on;
            hls on;
            hls_fragment 25s;
            hls_path /tmp/hls;
            gop_cache on;
        }

        application dash {
            live on;
            dash on;
            dash_path /tmp/dash;
        }

    }

}

3、重启nginx

sudo ./nginx -s reload

1935端口是默认的推流端口，浏览器查看，http:\\localhost:8080

三、ffmpeg推流

1、推流到nginx的rtmp服务

sudo ffmpeg -i rtsp://admin:azure2023@10.150.10.20:554/h264/ch1/main/av_stream -vcodec copy -acodec copy -f flv rtmp://localhost:1935/hls/haikang01

其中rtsp为摄像头的推流地址，rtmp为nginx搭建的服务地址，注意rtmp://localhost:1935/hls/haikang01地址要和nginx中配置一致，否则会出现：rtmp://localhost:1935/hls/haikang01: Input/output error错误，出现以下界面表示推流成功
