• Playing captured speex frames

  10 août 2014, par Fargo Fan

  We have a very odd mobile VoIP application and I’m trying to debug it. It looks like it uses speex as a codec, I tried to playback captured traffic but I have several problem and can’t find solution.

  So,

  1. I have captured traffic 535 KB.

  2. Using this simple Perl script I’ve dumped data into a file.

  The problem is that there is no software I can’t playback the file. (speexdec fails with "This doesn’t look like a Speex file". Obviously I need to add some headers to the file but have no idea how.

  Also I tried to merge the file with some speex sample file from the original website, but no player (VLC, ffmpeg, etc...) can play the second part of file.

  Is there a way to find out if the application really uses SPEEX codec or I’ve been misled by third party licence of the application ?

• headphone/webcam - output to stream server

  13 août 2014, par user867198

  I am in the process of making a C# desktop application. The application has to take microphone and webcam output. and it has to publish them to the server over RTMP protocol.

  I am not in this domain and does not have much idea about it. So i am in desperate need from someone, i have read all the SO question related with this and working towards FFMPEG tool to stream my web cam and headphone to server via RTMP.

  I appreciate any help on this. Even if someone explain the flow of what are the steps then it will be a good jump start for me. thank you.

• ffmpeg exec command not running in nginx rtmp

  22 février 2017, par evan

  I am using nginx and rtmp module to stream live hls and mpeg-dash.
  here is my rtmp command in nginx .conf

  rtmp {
  
  server {
  
      listen 1936;
  
  
  
  
  
      application mypull {
  
      live on ;
  
      meta copy;
  
      allow play all;
  
  
  
      pull rtmp://184.72.239.149/vod/BigBuckBunny_115k.mov name=test live=1;
  
  
  
  
  
      exec_push   /usr/bin/ffmpeg -re -i rtmp://localhost:1936/mypull/$name -vcodec libx264 -acodec libmp3lame -f flv rtmp://localhost:1936/hls/$name;
  
  
  
  
  
  }
  
  
  
  
  
  application dash {
  
          live on;
  
          dash on;
  
          dash_path /tmp/dash;
  
          dash_nested on;
  
          dash_fragment 5s;
  
          dash_playlist_length 30s;
  
      }
  
       application hls {
  
          live on;
  
          hls on;
  
      hls_playlist_length 30s;
  
      hls_fragment 5s;
  
          hls_path /tmp/hls;
  
      }
  
  }
  
  }

  but it is not playing. it seems that the ffmpeg command is not even running. and the hls and dash folders are empty. could anyone help me with it ?
