• Command to stream MPEG-1 video

  14 avril 2020, par xybrek

  I'm trying to stream MPEG-1 video over FFMPEG with

  



  ffmpeg -i "out.ts" -f flv -listen 1 -i rtmp://localhost:8889/live/app -c copy -f flv -listen 1 rtmp://localhost:1935/live/app


  



  The out.ts file is a MPEG-1 video encoded with

  



  ffmpeg -i out.avi -f mpegts -codec:v mpeg1video -b:v 1500k -r 30 -bf 0 -codec:a mp2 -b 0 -q 5 -t 1 out.ts


  



  When I try to open the stream with VLC : rtmp://localhost:1935/live/app media is not playing. What's the command to stream MPEG-1 video over FFMPEG ?

  


• 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)

  


• ffprobe : IGMP membership packet doesn't include source when localaddr is set to the non-default GW interface [closed]

  28 août 2023, par Chu N

  On a Ubuntu 18.04.6 LTS box with 2 interfaces e.g. eno1 (10.1.1.1/24), eno2 (10.2.2.2/24). The default route goes out eno1, however I need to send SSM membership reports via eno2 to join a multicast S,G stream on 232.0.0.5 sourced from 10.5.5.5.

  


  ffprobe version 3.4.11-0ubuntu0.1

  


  When I input the command :
ffprobe udp ://232.0.0.5:8000 ?localaddr=10.2.2.2&sources=10.5.5.5

  


  The outgoing IGMPv3 packet leaves via eno2 but it does NOT include the Source Address in the membership report group record field as observed on Wireshark.

  


  When I input the command to go out via eno1 :
ffprobe udp ://232.0.0.5:8000 ?sources=10.5.5.5
or
ffprobe udp ://232.0.0.5:8000 ?localaddr=10.1.1.1&sources=10.5.5.5

  


  The outgoing IGMPv3 packet leaves via the default GW eno1 and includes the Source Address in the IGMPv3 membership report group record field as observed on Wireshark.

  


  How do I make ffprobe include the Source Address in the IGMPv3 packet when using an interface that's not the default gateway ?

  


  I tried different formats of the UDP URL.
When I put the sources before localaddr(10.2.2.2), the IGMPv3 packet goes out via the default gateway (10.1.1.1).
I tried using a routing-policy on netplan to do some source routing under the eno2 stanza but it didn't work.
