  I am trying to apply animations for the particular video frame but hereby I’m not seeing that video frame by which I have to apply the animation. I only need fade in and fade out frame and display it as slide show video. Do you have any idea about this ?

   exec("ffmpeg -i input.mp3 -codec:a libmp3lame -b:a 128k output().mp3 2>&1", 
  
   $output, $exit_code);
  
   if ($exit_code!= 0) {
  
      $data['message'][] = "Error";
  
   }
  
  
  
   print_r($output);
  
   print_r($exit_code);
  
   exit;

  After running this code show error code 2.
  The output is an empty array and also exit_code is 2 and not create output.mp3 file.
