Is it possible to add video inside E-Mail Content??

This is my mail Code 

```
$to = 'my_mail@gmail.com';
$sub = 'my Subject';

$msg = '<html><body>';
$msg .= '<table rules="all" style="border: 1px solid #000000" cellpadding="10">';
$msg .= '<caption style="font-size: 18pt"><strong>Feedback from Customers</strong></caption>';
$msg .= "<tr><td width='25'><strong>Name</strong> </td><td width='60'>".strip_tags($_POST['name'])."</td></tr>";
$msg .= "<tr><td><strong>Email</strong> </td><td>" .strip_tags($_POST['mail']) . "</td></tr>";
$msg .= "<tr><td><strong>Country</strong> </td><td>" .strip_tags($_POST['country']) . "</td></tr>";
$msg .= "<tr><td><strong>Message</strong> </td><td>" . strip_tags($_POST['message']). "</td></tr>";
$msg .= "</table>";
