  15 juin 2014, par user3508453

  function getDuration($file){
  
          if (file_exists($file)){
  
           ## open and read video file
  
          $handle = fopen($file, "r");
  
          ## read video file size
  
          $contents = fread($handle, filesize($file));
  
          fclose($handle);
  
          $make_hexa = hexdec(bin2hex(substr($contents,strlen($contents)-3)));
  
          if (strlen($contents) > $make_hexa){
  
          $pre_duration = hexdec(bin2hex(substr($contents,strlen($contents)-$make_hexa,3))) ;
  
          $post_duration = $pre_duration/1000;
  
          $timehours = $post_duration/3600;
  
          $timeminutes =($post_duration % 3600)/60;
  
          $timeseconds = ($post_duration % 3600) % 60;
  
          $timehours = explode(".", $timehours);
  
          $timeminutes = explode(".", $timeminutes);
  
          $timeseconds = explode(".", $timeseconds);
  
          $duration = $timehours[0]. ":" . $timeminutes[0]. ":" . $timeseconds[0];}
  
          return $duration;
  
          }
  
          else {
  
          return false;
  
          }
  
  }

  This code is working fine but for some files it shows variable $duration is undefined even if the file exists ! please help someone.

• How to convert mp4 file to wav with the same duration ?

  16 octobre 2020, par York

  I want to convert an long Mp4 file to WAV with the same duration.
I tried to use ffmpeg with the args "aresample=async=1000" but there is still a difference :

  


  

  • the duration of the origin long MP4 is 03:28:05.936

  


  • the duration of the converted WAV is 03:28:05.35

  


  


  Is there any way can convert the MP4 file to WAV with the complete same duration ?

  


  Thanks !
