I tried to upload the video but did not get into the server continues, I wonder why huh?

my mime config

Code:

'wmv' => array('video/wmv', 'video/x-ms-wmv', 'flv-application/octet-stream', 'application/octet-stream'),
'flv' => array('video/x-flv', 'flv-application/octet-stream', 'application/octet-stream'),
'mp4' => 'video/mp4',
'3gp' => 'video/3gpp'

my view

Code:

<div id="upload">
            &lt;?php
            echo form_open_multipart('audio');
            echo form_upload('userfile');
            echo form_submit('upload','Upload');
            echo form_close();
            ?&gt;
</div>

my controller

Code:

function index() {
        $this->load->model('Audio_model');
        if ($this->input->post('upload')) {
            $this->Audio_model->do_upload();
        }
        $this->load->view('v_audio');
    }

and my model

Code:

function do_upload() {
        $config = array(
            'allowed_types' =>  'mp4|3gp|flv|mp3',
            'max_size'=>'100000',
            'upload_path' => $this->gallery_path
        );
        $this->load->library('upload', $config);
        if ($this->upload->do_upload()) {
            echo "Upload success!";
        } else {
            echo "Upload failed!";
        }
    }

Add mime type in the config/mimes.php

Code:

'flv'    => array('video/x-flv', 'flv-application/octet-stream', 'application/octet-stream'),
'mp4' => 'video/mp4',
'3gp' => 'video/3gpp'
