Customizing the error for file upload in codeingiter - php

Question

I have a from with two file uploads: one for image upload and another for video uploading. Now the problem is that, if I upload invalid file types for either video or image, it is showing the same error
The filetype you are attempting to upload is not allowed.
What I need is to customize the error so that for video it will be like
The video you are attempting to upload is not allowed.
How can I make this possible? I am sharing the section of code for video and image.
View Page Code:
<tr>
<td>
<label for="video_type">Video Genre <span class="required">*</span></label>
</td>
<td>
<?php
$array['']="Select";
foreach($genre as $row)
{
$array[$row->id] = $row->genre;
}
echo form_dropdown('video_type',$array, set_value('video_type'));
?>
</td>
<td>
<?php echo form_error('video_type'); ?>
</td>
</tr>
<tr>
<td>
<label for="uploader_id">Upload Video <span class="required">*</span></label>
</td>
<td>
<input type="file" name="video" class="input" value="<?php echo set_value('video'); ?>" />
</td>
<td>
<?php echo form_error('video'); ?>
</td>
</tr>

try this
if (empty($_FILES['video']['name']))
{
$this->form_validation->set_message('required', 'video name incorrect'); //put this line above this statement
$this->form_validation->set_rules('video', 'Video', 'required');
}
