  17 février 2014, par Mustafa Ekici

  How i can get stream from Ip Camera, Its using RTP, stream is MPEG4, i have multicast address and port,and i have ip camera's IP address and Port Number.
  And I cant reach via http forexample (http://ip/jpeg) And I cant reach stream with VLC Player too. forexample (rtp ://ipadressofcam:port) and (rtp ://multicastaddress:port)
  So What is ffmpeg command of that ?
  I have windows OS, I only write code with C# right now.
  But producer created their own ocx which used for viewing cam,that plugin can work on .net but i dont want to use it becouse it doesnt have much funcionality, I mean you cant get current picture or snapshot of cams, thats why i have to do it myself.

• Running FFMpeg on the server (to save the user from waiting)

  26 juin 2013, par Tom

  I have made a simple page that lets a user upload videoes for then to display all the videoes uploaded using the HTML5 <video></video> tags. But to provide the user with full browser support I need to transcode all the videoes that are being uploaded into a few new formats. The problem is then that now I am transcoding all vidoes into two different formats, which in turn takes a long time and it makes the user have to wait for the video being transcoded. Is there a simple way that anyone know of that lets me run this script in "the background" so that the user experience is in no way being compromised with long wait times ?

  I am running the FFMpeg scripts using PHP with the exec command.

• How to save file to s3 after processing by ffmpeg using carrierwave

  25 septembre 2013, par loganathan

  I am trying to convert the bit rate of the Mp3 file before uploading to S3, I can able to create version for the mp3 file but the version is not saving in s3 instead original file is uploading to s3.

    version :bitrate_96k do
  
      process :resample => "96"
  
    end
  
  
  
  def resample(bitrate)
  
      tmp_path   = File.join( File.basename(current_path), "tmpfile" )
  
      File.rename current_path, tmp_path
  
      audio_details  = `ffmpeg -i '#{tmp_path}' 2>&1`.split(",").split("\n").flatten
  
      file_bitrate =  audio_details.grep(/bitrate/).grep(/bitrate/).join.split("bitrate: ").last.split("\s").first
  
      unless file_bitrate == bitrate
  
        `ffmpeg -i #{tmp_path.shellescape}  -acodec libmp3lame -y -ab 96k #{current_path.path}`
  
        File.unlink(current_path)
  
       FileUtils.mv(temp_path, current_path)
  
      end
  
    end
