Setting uploaded video's value in form in codeigniter

Question

I am trying to upload a video file in my project. I have included form validation in my form and video field have required validation. The problem is, even if I have given all values, the form is not getting submitted. It is showing error as The Video field is required (form validation error).

Controller function - index():

function index()
    {           
        $this->form_validation->set_rules('name', 'Name', 'required|trim|xss_clean|max_length[255]');           
        $this->form_validation->set_rules('video_type', 'Video genre', 'required');         
        $this->form_validation->set_rules('language', 'Language', 'required');      
        $this->form_validation->set_rules('length', 'Length', 'required|is_numeric');           
        $this->form_validation->set_rules('tralier', 'Tralier', 'is_numeric');          
        $this->form_validation->set_rules('link', 'Link', 'max_length[255]');           
        $this->form_validation->set_rules('thumb_image', 'Thumb Image', 'required|max_length[255]');            
        $this->form_validation->set_rules('video', 'Video', 'required');            
        $this->form_validation->set_rules('description', 'Description', 'required|xss_clean|max_length[500]');          
        $this->form_validation->set_rules('keywords', 'Keywords', '');

        <?php echo form_submit( 'submit', 'Submit'); ?>
</td>

<?php echo form_close();

$this->load->view('layout/footer');?>

Can anybody help me to find the problem why the form is not getting submitted. I am not getting any filetype/size error.

Thanks in advance.

Change

 $this->form_validation->set_rules('video', 'Video', 'required');    

to

if (empty($_FILES['video']['name']))
{
    $this->form_validation->set_rules('video', 'Video', 'required');
}
