• How to run ffmpeg on demand when someone opens my website with the player where a remote IP camera is displayed ?

  8 mai 2023, par alexiter

  I set up an nginx server to stream from an IP camera located elsewhere, I used a windows server because it was the one I had no use for (I usually prefer linux), I would need to know how I can make the ffmpeg command run only when someone opens the website where the player is located.

  


  This is my nginx.conf server code :

  


  worker_processes  1;

error_log  logs/error.log info;

events {
    worker_connections  1024;
}
rtmp {
    server {
        listen 1935;
        ping 30s;
        notify_method get;
        application live {
            live on;
            on_publish http://*******:8080/auth;
            dash on; 
            dash_path tmp/dash;
            
            
        }
    }
}
http{

   server {
        listen 8080;
        location /auth {
        if ($arg_psk = '*****') {
    return 201;
    }
  return 404;
  }
}
   
   server {
        listen 8443 ssl;
        server_name stream.*****.com;
        
        ssl on;
        ssl_certificate C:/Certbot/live/stream.*****.com/fullchain.pem;
        ssl_certificate_key C:/Certbot/live/stream.****.com/privkey.pem;
        ssl_session_timeout 5m;
        charset utf-8;
        location /dash {
            root tmp;
            add_header Cache-Control no-cache;
        }
        location / {
            root www;
        }
        

   }
}



  


  The command that I use from the DOS console in windows is this :

  


  ffmpeg -rtsp_transport tcp -i rtsp://*****:******@******.com:557/Streaming/Channels/101 -c copy -f flv -y -t 35 rtmp://********:1935/live/stream?psk=********


  


  Basically what I need is that ffmpeg is not running constantly, only when someone wants to view the video from the IP camera. (I have programmed ffmpeg to finish after 35 seconds, although I will put five minutes later)

  


• lavf/dashenc : update bitrates on dash_write_trailer

  lavf/dashenc : update bitrates on dash_write_trailer
  Provides a way to change bandwidth parameter inside DASH manifest after a non-CBR H.264 encoding.
  
  Caller now is able to compute the bitrate by itself, after all packets have been written, and then set that value in AVFormatContext->streams->codecpar->bit_rate before calling av_write_trailer. As a result that value will be set in DASH manifest.

• webmdashenc : parameter’ize minimumUpdatePeriod

  22 avril 2015, par Vignesh Venkatasubramanian

  webmdashenc : parameter’ize minimumUpdatePeriod
  Some players do not support setting minimumUpdatePeriod to zero.
  
  This patch adds a new parameter that will let the users set any
  
  value to this field. Also updates the test and the documentation.
