Player card on validation not redirecting to desired given url


#1

HI,
I have been trying to implement player card but the url it showing in preview is not desired given video url.
these are my meta tags

 <?php
	$https_url = base_url('/assets/plugins/cards-player-samples-master/player/');		
	$player = $https_url."/container.html";		
	$image = $https_url."/example.png";		
?>
<meta content='text/html; charset=UTF-8' http-equiv='Content-Type'/>
<meta name="twitter:card" content="player">
<meta name="twitter:site" content="@GauravDhimanG">
<meta name="twitter:title" content="Testing video">
<meta name="twitter:description" content="This is a sample video.">
<meta name="twitter:image:width" content="480">
<meta name="twitter:image:height" content="480">
<meta name="twitter:image" content="<?php echo $image; ?>">
<meta name="twitter:player" content="<?php echo $player; ?>">
<meta name="twitter:player:width" content="480">
<meta name="twitter:player:height" content="480">
<meta name="twitter:player:stream" content="">
<meta name="twitter:player:stream:content_type" content="video/mp4">

this is the screenshot of validator

Please help into this and why it was showing WARN: this card is redirected to http://www.btvin.com/
