  27 mai 2012, par PHPLearner

  i am using below code in the exec() command, it works in other server, in my dev region just converting into empty flv file.

  i have paid to my host to reinstall the ffmpeg, they have confirmed its good still not getting the output.

  they are claiming that i have a issue in the below syntax. does any one have any thoughts on this ?

  ffmpeg -i /home/hereitis/uploads/videos/MVI_0572.AVI -f flv -s 320x240 /home/hereitis/videos/flv/MVI_0572.flv 

  Thank you so mcuh for your interest to read this.

• Video converted to FLV using FFMPEG gets 0 size

  11 novembre 2011, par Sudhir

  I'm trying to convert avi file to flv format using FFMPEG on server, but its giving me problems. On conversion, the file is converted to flv format but no data (0 kb size file). Tried debugging the code but could not. The FFMPEG is installed in CentOS, in path /usr/bin/ffmpeg, and i'm using following command for conversion :

  $srcFile = "/home/mydomain/public_html/demo/test/sample.avi" ;
  $destFile = "/home/mydomain/public_html/demo/test/sample_again.flv" ;
  $ffmpegPath = "/usr/bin/ffmpeg" ;
  
  $flvtool2Path = "/usr/local/bin/flvtool2" ;
  $command = $ffmpegPath . " -y -i " . $srcFile .  " -ar 32000 -ab 32000 -f flv -s 320x240 ".
  
  $destFile . " | " . $flvtool2Path . " -U stdin " . $destFile ;
  exec($command, $output) ;
  
  print_r($output) ;
  

  I tried doing :

  exec("which ffmpeg") ;
  

  And it gave me the path /usr/bin/ffmpeg, but get following error when i execute the code :

  Array (

  ) 
  

  What could be the problem. Is this the problem of Flvtool2, if yes then what is it. Please suggest something
