• How can I debug this rtmp stream ? It wont play on Vlc, and logs show no error

  12 avril 2020, par SquirrelSenpai

  I am creating a rtmp stream using FFMPEG and sending the data to local NGINX server with the RTMP module.

  



  When playing the stream in VLC I am unable to hear any music. Have I missed something ?

  



  No FFMPEG errors according to logs

  



  fmpeg -hide_banner -loglevel warning -i http://x.x.x.x:8138 -f mp3 rtmp://localhost/live


  



  To test VLC >> Open Network Stream >> rtmp ://localhost/live

  



  Nginx.conf

  



  worker_processes auto;
pid /run/nginx.pid;
include /etc/nginx/modules-enabled/*.conf;

events {
        worker_connections 768;
        # multi_accept on;
}

rtmp_auto_push on;

rtmp{

        server{

                listen 1935;

                application live {

                        # enable live streaming
                        live on;
                        record off;

                        # publish only from localhost
                        allow publish all;
                        allow play all;

                }

        }

}

• MSE Does not show duration when MPEG-DASH segments are created with FFmpeg

  15 mars 2023, par WaveLink

  I am trying to create a system that streams DASH segments to the browser, where it gets decoded by Media Source Extensions. When using MP4Box, the init segment loads the duration into the player, but the version generated by FFmpeg does not.

  


  I believe this is due to some sort of header missing from the init segment generated by FFmpeg, but I have not been able to figure it out. Here is the command I use to generate the files :

  


  ffmpeg -i .\source.opus -c:a libopus -c:v none -seg_duration 1 -dash_segment_type mp4 -preset ultrafast -use_timeline 1 -use_template 1 -streaming 1 -init_seg_name "segment_init.mp4" -media_seg_name "segment_$Number$.m4s" -fflags +genpts -f dash ./out.mpd
When using MP4Box, this is the config I use :

  


  MP4Box -dash 1000 -rap -profile live -segment-name "segment_$Number" .\out.mp4
In both cases, the audio does play, and both of them contain similar headers, but the FFmpeg version just does not contain the media duration in the init segment, or at least the MSE implementation cannot read it.

  


  I tested this in Chrome, Firefox, and Edge, and all of them behave the same.

  


  Thanks for any help.
