and here's the script for the backend side
class video_streaming extends CI_Controller{
public function __construct() {
parent::__construct();
@session_start();
$this->load->library('encrypt');
//$this->load->model('fileupload_model');
}
function stream()
{
if (! preg_match('/^[-a-z.-@,\'\s]*$/i',$_GET['ID']))
{
die('Invalid name proved, the name may only contain a-z, A-Z,
0-9, "-", "_" and spaces.');
}
else
$empty=strlen($_GET['ID']);
if ($empty==0)
{
die('The text field cannot be empty');
}
else
{
//the input data is clean, retrieve text data input
$ID = $_GET['ID'];
}
$ID = mysql_real_escape_string(stripslashes($ID));
$result_video = $this->db->query("SELECT * FROM td_post WHERE
post_id='$ID'")->result_array();
$direction = $result_video[0]['post_file'];
//close the connection
//change the path to use absolute server path, revised on February
4, 2011
$path= base_url().$direction;
header('Content-type: video/wmv');
//2015236 is the exact file size of the video, change it to
according to your video file size
//header('Content-Length: 2015236');
header("Expires: -1");
header("Cache-Control: no-store, no-cache, must-revalidate");
header("Cache-Control: post-check=0, pre-check=0", false);
readfile($path);
}
}
the file doesnt run
when i used this link directly into the browser addressbar, i get a file
to download with no extension, when i change it to my desired extension,
then i can p[lay it on desktop media palyer,
can anybody tell me whats the issue over here??
