• Can't obtain thumbnail with ffmpeg codeigniter

  2 avril 2015, par DMBorges

  I have used the following tutorial ( https://www.youtube.com/watch?v=qT4hN5o57hI) to try to obtain a thumbnail from a uploaded video using codeigniter as a framework. As I am new to all this I don’t understand if at the end of supposedly uploading my video the code failed to create a thumbnail, if my created thumbnail is somewhere lost in my computer of by some settings reasons ffmpeg is not working.

  Where does my $imageFile goes to ?

  Here is my code.

  MY VIEW

  <div>
  
  
  
              &lt;?php echo form_open_multipart('gallery/save/'); ?>
  
                  <table class="table">
  
                      <tr>
  
                          <td>Video</td>
  
                          <td>&lt;?php echo form_upload('pic'); ?></td>
  
                      </tr>
  
                      <tr>
  
                          <td>Descrição</td>
  
                          <td>&lt;?php echo form_input('description'); ?></td>
  
                      </tr>
  
                      <tr>
  
                          <td></td>
  
                          <td>&lt;?php echo form_submit('upload', 'Guardar', 'class="btn btn-primary"'); ?></td>
  
                      </tr>       
  
                  </table>
  
  
  
      </div>
