Nginx搭建RTMP服務器+FFmpeg實現海康威視攝像頭預覽

場景

Windows上搭建Nginx RTMP服務器並使用FFmpeg實現本地視頻推流：

https://blog.csdn.net/BADAO_LIUMANG_QIZHI/article/details/120868728

在上面實現的是對本地視頻的推流，要對接海康威視攝像頭獲取視頻流並推流和預覽。

實現

1、使用Nginx搭建RTMP服務器

流程和上面搭建的時候一致。完整nginx的配置再記錄一遍

#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 1935;
 
        application live {
            live on;
        }
  
        application hls {
            live on;
            hls on; 
            hls_path temp/hls; 
            hls_fragment 8s; 
        }
    }
}
 
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  65;
 
    #gzip  on;
 
    server {
        listen       110;
        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;
        }
 
        # 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
    #
    #server {
    #    listen       8000;
    #    listen       somename:8080;
    #    server_name  somename  alias  another.alias;
 
    #    location / {
    #        root   html;
    #        index  index.html index.htm;
    #    }
    #}
 
 
    # HTTPS server
    #
    #server {
    #    listen       443 ssl;
    #    server_name  localhost;
 
    #    ssl_certificate      cert.pem;
    #    ssl_certificate_key  cert.key;
 
    #    ssl_session_cache    shared:SSL:1m;
    #    ssl_session_timeout  5m;
 
    #    ssl_ciphers  HIGH:!aNULL:!MD5;
    #    ssl_prefer_server_ciphers  on;
 
    #    location / {
    #        root   html;
    #        index  index.html index.htm;
    #    }
    #}
 
}

2、啟動nginx后，在FFmpeg.exe目錄中再新建bat啟動腳本

ffmpeg.exe -i "rtsp://admin:admin123456@攝像頭的ip:554/h264/ch1/main/av_stream" -vcodec copy -acodec copy -f flv rtmp://localhost:8822/hls/badao
pause

腳本說明：

海康威視攝像頭，

它的rtsp數據流的地址為：rtsp://[username]:[password]@[ip]:[port]/[codec]/[channel]/[subtype]/av_stream
說明：
username: 用戶名。例如admin。
password: 密碼。例如12345。
ip: 為設備IP。例如 192.0.0.64。
port: 端口號默認為554，若為默認可不填寫。
codec：有h264、MPEG-4、mpeg4這幾種。
channel: 通道號，起始為1。例如通道1，則為ch1。
subtype: 碼流類型，主碼流為main，輔碼流為sub。

3、雙擊腳本啟動FFmpeg實現攝像頭推流

4、然后打開VLC播放器-媒體-打開網絡串流

輸入地址
