• How save an audio buffer with Fluent FFmpeg

  17 juin 2016, par Luke

  I have a Buffer object that contains audio data and I’m wondering if I can save this Buffer through Fluent FFmpeg without writing it to a file temporary first.

  I came across this other question : fluent-ffmpeg module : "end" event does not fire

  Which seems to do what I need but with video, however, this technique doesn’t seem to work for me. I get the following error :

  ffmpeg write error 'Input stream error: not implemented'

  How can I pipe a Buffer directly to Fluent FFmpeg without writing it to a temporary file first ?

• How can I get audio in my ffmpeg stream to nginx rtmp server ?

  26 novembre 2013, par Conor Patrick

  I currently have a nginx server setup with the rtmp plugin for video streaming. I'm streaming to it with ffmpeg and then displaying the stream on a web browser with adobe flash player.

  I have the video streaming successfully but I have not been able to get audio.

  This is the ffmpeg command I use to start the stream

  ffmpeg -f video4linux2 -s 320x240 -r 16 -i /dev/video0 -f alsa -i hw:0 -an -f flv rtmp://123.456.789.51:31002/rover/mystream

  The stream then goes to nginx which is running on this conf file

  worker_processes  1;
  
  
  
  error_log  logs/user/error.log debug;
  
  
  
  events {
  
      worker_connections  1024;
  
  }
  
  
  
  rtmp {
  
      server {
  
          listen 31002;
  
  
  
          application rover {
  
              live on;
  
              #meta copy;
  
              #interleave on;
  
              allow publish all;
  
              allow play all;
  
  
  
              hls on;
  
              #record keyframes;
  
              #record_path /tmp;
  
              #record_max_size 128K;
  
              #record_interval 30s;
  
              #record_suffix .this.is.flv;
  
  
  
              #on_publish http://localhost:8080/publish;
  
              #on_play http://localhost:8080/play;
  
              #on_record_done http://localhost:8080/record_done;
  
          }
  
      }
  
  }
  
  
  
  http {
  
      server {
  
          listen      26360;
  
  
  
          location /stat {
  
              rtmp_stat all;
  
              rtmp_stat_stylesheet stat.xsl;
  
          }
  
  
  
          location /stat.xsl {
  
              root nginx-rtmp-module-master/;
  
          }
  
  
  
          location /control {
  
              rtmp_control all;
  
          }
  
  
  
          #location /publish {
  
          #    return 201;
  
          #}
  
  
  
          #location /play {
  
          #    return 202;
  
          #}
  
  
  
          #location /record_done {
  
          #    return 203;
  
          #}
  
  
  
          location /rtmp-publisher {
  
              root /path/to/test;
  
          }
  
  
  
          location / {
  
              root nginx-rtmp-module-master/test/www;
  
          }
  
      }
  
  }

  I then access the stream from a browser using this set up for the adobe flash player and strobe media player.

  Could I get some suggestions as to how I couldn't be getting audio ? I'm streaming video from my webcam and specifying audio from my mic.

• MPEG-DASH Encoding for Live Streaming

  16 mai 2016, par Mcp

  I want to do encode a live stream for MPEG-DASH in various bitrates and resolutions for live playback.

  Everything I found so far either uses only the source resolution (Nimble, nginx-rtmp-module) or seems to be only for VOD streaming(DASHEncoder).

  Is it possible to use DASHEncoder with a live input (rtmp stream) and how would I do that ?
  If not, is it possible to use nginx-rtmp + ffmpeg for what I want to do ?
