• Convert stream to a stream on the fly with ffmpeg/avconv

  6 juillet 2014, par Apacci

  I’m trying to convert flv stream to another mp3 or ogg stream. The point is I want to use mp3/ogg stream on HTML5 page, because flv stream can’t be played with HTML5. So, I configured avserver.conf :

  Port 8090
  
  BindAddress 0.0.0.0
  
  MaxHTTPConnections 2000
  
  MaxClients 1000
  
  MaxBandwidth 1000
  
  CustomLog -

      FileMaxSize 200K
  
      ACL allow 127.0.0.1
  
  </feed>
  
  
  
  <stream>
  
      Feed feed1.ffm
  
      Format ogg
  
      AudioBitRate 64
  
      AudioChannels 1
  
      AudioSampleRate 44100
  
      NoVideo

  <stream>

  </stream>

  the command I use :

  avconv -i http://some_stream_service?format=flv -acodec mp3 http://localhost:8090/feed1.ffm

  console output :

  It looks like working, but I keep getting 0 bytes on web page http://localhost:8090/test1.ogg. Does anybody have ideas what I’m doing wrong ?

• FFMPEG : Use expression calculated from timestamp to drawtext [closed]

  26 décembre 2020, par NicolasV

  Using ffmpeg and draw text, I need write on the video something like that :

  


  text=1+floor(BPM * mod(1000*t-StartCounter ;480000/BPM)/60000).

  


  I don't know if I need use PTS or t.

  


  StartCounter would be a variable in milliseconds, the text would appear at this point.

  


  BPM is an integer variable between 100 and 180.

  


  I would draw for instance with StartCounter = 3256 and BPM = 120.

  


  Any help appreciated, thanks
