• 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.

• ffmpeg split video H264 stutters on Windows Media Player

  9 mars 2019, par Juan Foegen

  I am converting and splitting wmv and mp4 into new mp4 files. I am using ffmpeg to do the conversion with simply :
  ffmpeg -i inputfile.wmv -vcodec libx264 -ss 00:00:10 -t 00:00:15 outputfile.mp4

  So when I create my split video it plays fine on other video players, like VLC, but stutters when initially playing on Windows Media Player and even shows a blank screen for a moment and then after about 5 seconds, the video will play normally. If I then select play again without reloading, Windows Media Player will play the video fine, with no stuttering.

  If I REMOVE the start parameter when doing the conversion, then the resulting video will play without issues on all my players, INCLUDING Windows Media Player.

  I have tried changing the frame rate, the bit rate and altered different optimization options mentioned here - https://trac.ffmpeg.org/wiki/Encode/H.264

  I need the split video to play on Windows machines on Windows Media Player and on the web streamed using the video element. This is why I chose H264 codec and MP4.

  Has anyone had issues playing ffmpeg split videos using H264 codec with Windows Media Player ? I am using the latest version of ffmpeg. Anyone have any other suggestions on any different settings I could try to adjust ?

  Thanks
