  27 février 2013, par Light

  I am trying to create a video thumbnail with FFMPEG using the following script.
  However I am getting return value of 1. What does it mean ? What is error code 1 ? I have Googled it and didn't find and answer. Thanks.
  Here is the code :

  <?php
  
  
  
          //thumb path should be added in the below code
  
          //test for thumb
  
          $dir_img='uploads/';
  
          $mediapath='thumb.jpg';
  
          $file_thumb=create_movie_thumb('test.mp4',$mediapath,$mediaid);
  
  
  
          $name_file=explode(".",$mediapath);
  
          $imgname="thumb_".$name_file[0].".jpg";
