• What does the ffmpeg loglevels mean ? [closed]

  2 avril 2013, par naxa

  FFmpeg has several loglevels (see -loglevel). These are, in order : quiet, panic, fatal, error, warning, info, verbose and debug.

  But the documentation is not very verbose with explaining their meanings.

  It's true that all names are self-documenting enough so they give some intuitive sense for when to use them. But when in doubt, from the user as well as the developer's perspective, in decision situations, it would help to have a clear definition of each level.

  I would like to know which one is for what purpose, in order to know when to use them. I couldn't find any more hints on this. Especially on the difference between panic, fatal, error and info, verbose, debug.

  I think I've found the code for these but I still don't know their exact purposeful 'boundaries'. Is there an explanation on this, (perhaps outside the ffmpeg project) ?

• Can't get watermark on my nginx-rtmp live streams with ffmpeg

  8 juillet 2020, par mallebabbe

  Goodday,

  



  I'm trying to get my livestreams watermarked but for some reason the streams aren't transcoded with the image I want to have on top.

  



  My current build is :

  



  

  • Stream from OBS to Nginx-RTMP server

  


  • In the nginx.conf I've an app configured with the name live which should trigger ffmpeg execution and transfer the output to the push app to deliver the final stream to the different Social Media platform

  


  



  All is working without the ffmpeg execution.

  



  My OBS Stream configuration looks like this ;
rtmp://xxx.xxx.xxx.xxx:1935/live

  



  My configuration looks like this :

  



  events {
    worker_connections  1024;
}
# RTMP configuration
rtmp {
    server {
        listen 1935; # Listen on standard RTMP port
        chunk_size 4000;

# Define Live
        application live {
        live on;
        exec /bin/ffmpeg -loglevel info -i rtmp://localhost:1935/live/$name
                 -vf "movie=/etc/nginx/images/logo.png[logo];[0][logo]overlay=0:960"
                 -c:v flv -f flv rtmp://localhost:1935/push/$name;
        }

# Define the Push Application
        application push {
        live on;
        push rtmp://a.rtmp.youtube.com/live2/xxxx-xxxx-xxxx-xxxx-xxxx;
        push rtmp://rtmp.mixcloud.com/broadcast/xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxx_xxxxxxx-x;
        push rtmp://live-ams.twitch.tv/app/live_xxxxxxxx_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx;
        push rtmp://127.0.0.1:19350/rtmp/xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx;
        }

# Define the Application
        application show {
            live on;
            # Turn on HLS
            hls on;
            hls_path /mnt/hls/;
            hls_fragment 3;
            hls_playlist_length 60;
            # disable consuming the stream from nginx as rtmp
            deny play all;
        }
# RTMP video on demand for mp4 files
        application vod {
            play /mnt/mp4s;
        }
        # RTMP stream using OBS
        application stream {
            live on;
        }
    }
}
http {
    sendfile off;
    tcp_nopush on;
    aio on;
    directio 512;
    default_type application/octet-stream;
    server {
        listen 8080;
        location / {
            # Disable cache
            add_header 'Cache-Control' 'no-cache';
            # CORS setup
            add_header 'Access-Control-Allow-Origin' '*' always;
            add_header 'Access-Control-Expose-Headers' 'Content-Length';
            # allow CORS preflight requests
            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;
            }
            types {
                application/dash+xml mpd;
                application/vnd.apple.mpegurl m3u8;
                video/mp2t ts;
            }
            root /mnt/;
        }
    }
}


  



  Nginx likes this configuration when I check it with nginx -t but there is no out stream send to the Social Media platforms and the logging stays empty.

  



  Hope you guys can help me, I don't see it.
