Local IP camera rtsp feed send to remote RTMP server and then play as hls live video stream

 To receive RTSP feed at server we need to install NginX and RTMP module at server side. 

Then we need to configure rtmp configure at nginx.conf from /etc/nginx/nginx.conf

rtmp {

    server {

        listen 8000; # Listen on standard RTMP port

        chunk_size 4000;

        application live {

            live on;

            # Turn on HLS

            # HLS Configuration

      hls on;

      hls_path /var/www/chatapp.thinkfoundation.com.bd/hls/;

      hls_fragment 3;

      hls_playlist_length 60;

      # Use a custom name for the HLS segment files

            hls_fragment_naming system;

            hls_fragment_naming_granularity 1;

        }

    }

}

and also update the server block of nginx config file. It could be nginx.conf or /etc/nginx/sites-available/ folder config file.

Use following server block to get the hls feed

server {

    listen 80;

    server_name chatapp.thinkfoundation.com.bd;  # replace with your domain or IP address

    location / {

        root /var/www/chatapp.thinkfoundation.com.bd/hls/;  # replace with the path to your HLS files

        add_header Cache-Control no-cache;

        add_header 'Access-Control-Allow-Origin' '*' always;

        # You can add more headers as needed

        # Enable CORS for HLS

        if ($request_method = 'OPTIONS') {

            add_header 'Access-Control-Allow-Origin' '*';

            add_header 'Access-Control-Max-Age' 1728000;

            add_header 'Content-Type' 'text/plain charset=UTF-8';

            add_header 'Content-Length' 0;

            return 204;

        }

        # Handle HLS files

        location ~ \.m3u8$ {

            types { application/vnd.apple.mpegurl m3u8; }

            add_header Cache-Control no-cache;

            add_header 'Access-Control-Allow-Origin' '*' always;

            # You can add more headers as needed

        }

        location ~ \.ts$ {

            add_header Cache-Control no-cache;

            add_header 'Access-Control-Allow-Origin' '*' always;

            # You can add more headers as needed

        }

    }

}

Now your live feed url will be: 
example 

http://chatapp.thinkfoundation.com.bd/.m3u8

Make sure that you send your local rtsp feed to remote server using following command:

ffmpeg -i "rtsp://admin:hik12345@192.168.100.40:554/Streaming/Channels/101" -filter:v fps=fps=30 -crf 40 -preset ultrafast -vcodec libx264 -f flv "rtmp://157.245.58.124:8000/live"

you need ffmpeg library to execute upper command to send rtsp feed to rtmp server.
