• Http live stream video segmenting. non-Mac approach

  20 juin 2012, par Agzam

  Anyone knows a good way to use http live streaming tools on non-Mac platforms ?
  Can you tell me at least if there's good alternatives ? I need mediafilesegmenter and mediastreamvalidator.

  Or maybe anyone has a source code or something like that...

  UPD : I've tried different segmenters, most of them are based on Carson's open-sourced segmenter. Now the difference between Apple's mediafilesegmenter and this one, that it takes only a transport stream, not just any video. And I need to segment h264 videos.
  When I use ffmpeg to convert h26s to mpeg-ts I'm getting much bigger files in the end. Even if I try to preserve same audio codec (aac) it changes video codec form avc to mpeg-ts.

  Damn I hate Apple. How can they propose that thing as a standard if they don't even provide workarounds for another platforms.

  I still need to find a way to segment h264 videos, and keep in the segmented files avc and aac codecs.

• Anomalie #4543 : Accessibilité des chargements ajax (live regions)

  8 septembre 2020, par nicod _

  Je viens d’avoir une confirmation par une autre experte accessibilité qu’il faut supprimer ces attributs : https://mamot.fr/@lena/104822641354406079

  La subtilité serait donc éventuellement de placer aria-live="polite" sur le premier résultat lors d’une pagination uniquement.

• 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.
