manual Resize video through php

I was wondering if anyone could tell me how I can set the dimensions for my video through php.
here is an example of the php code i would like to edit.

<?php get_header();

global $post_id,$cs_transwitch;
$cs_layout = ”;
$post_xml = get_post_meta($post->ID, “post”, true);
if ( $post_xml <> “” ) {
$xmlObject = new SimpleXMLElement($post_xml);
$cs_layout = $xmlObject->cs_layout;
$cs_sidebar_left = $xmlObject->cs_sidebar_left;
$cs_sidebar_right = $xmlObject->cs_sidebar_right;
}
if ( $cs_layout == “left” ) {
$cs_layout = “two-thirds column right”;
$show_sidebar = $cs_sidebar_left;
}
else if ( $cs_layout == “right” ) {
$cs_layout = “sixteen columns left”;
}
else $cs_layout = “sixteen columns left”;
?>
<div class=”container row”>

<?php if ( have_posts() ): while ( have_posts() ) : the_post();
global $post_id;
?>
<div class=”<?php if(isset($cs_layout)) echo $cs_layout;?> “>
<div id=”post-<?php the_ID(); ?>” <?php post_class(); ?>>

<div class=”in-sec row”>
<div class=”blog-detail detail-page”>
<?php
$image_id = get_post_thumbnail_id ( $post->ID );
if ( has_post_video() ) {
the_post_video();
}

if($image_id <> ”){
//$image_url = wp_get_attachment_image_src($image_id, array(auto,auto),true);
$image_url = cs_attachment_image_src($image_id, auto, auto);
?>

<?php
// getting featured image start
echo ““;
// getting featured image end

<?php }
featured();
