• How to convert mp4 files into mp3 on button click using ffmpeg/php ?

  4 juin 2019, par flash

  I am working on a php code as shown below where I am converting mp4 files into mp3 using system command ffmpeg (in the case statement below).

  <?php 
  
  
  
  $mp4_files = preg_grep('~\.(mp4)$~', scandir($src_dir)); 
  
  
  
  foreach ($mp4_files as $f)
  
   {
  
  
  
       $parts = pathinfo($f);
  
       switch ($parts['extension'])
  
       {
  
           case 'mp4' :
  
               $filePath = $src_dir . DS . $f;
  
               system('ffmpeg -i ' . $filePath . ' -map 0:2 -ac 1 ' . $destination_dir . DS . $parts['filename'] . '.mp3', $result);  // Through this command conversion happens. 
  
       }
  
   }
  
  
  
  $mp3_files = preg_grep('/^([^.])/', scandir($destination_dir));
  
  
  
  ?>

  After conversion, mp3 files goes into destination_dir. If new mp4 file arrives in $src_dir, the conversion usually happen on refresh of a page.

  Once the conversion is complete, I am parsing everything into table as shown below :

  <table>
  
     <tr>
  
        <th style="width:8%; text-align:center;">House Number</th>
  
        <th style="width:8%; text-align:center;">MP4 Name</th>
  
        <th style="width:8%; text-align:center;">Action/Status</th>
  
     </tr>
  
     &lt;?php
  
        $mp4_files = array_values($mp4_files);
  
        $mp3_files = array_values($mp3_files);
  
        foreach ($programs as $key => $program)    { 
  
           $file = $mp4_files[$key];     
  
           $file2 = $mp3_files[$key];   // file2 is in mp3 folder
  
        ?>
  
     <tr>
  
        <td style="width:5%; text-align:center;"><span style="border: 1px solid black; padding:5px;">&lt;?php echo basename($file, ".mp4"); ?></span></td> 
  
        <td style="width:5%; text-align:center;"><span style="border: 1px solid black; padding:5px;">&lt;?php echo basename($file); ?></span></td>              
  
        <td style="width:5%; text-align:center;"><button style="width:90px;" type="button" class="btn btn-outline-primary">Gotd>  
  
     </button></td></tr>
  
     &lt;?php } ?>
  
  </table>

  Problem Statement :

  I am wondering what changes I should make in the php code above that on click of a Go button, conversion of individual mp4 into mp3 happen.

  On clicking of Go button, individual mp3 file (from an mp4) belonging to an individual row should go inside destination directory ($destination_dir).
