how can you stop Vimeo video player automatically when clicking slider arrows?

Question

I've run into an issue with a Vimeo player that's been set up for a site I'm working on. I have a friend who implemented the slider. The way it's setup is there is an introductory video embedded from Vimeo on the first slide on the homepage, which only shows up on the homepage. The problem is that when a user clicks on either of the arrows of the slider, the video keeps playing even though you click the pause button on the Vimeo video player.

Is there a way to automatically stop the Vimeo video player when the user clicks on either the left or right arrows of the slider (upon advancement to the next slide)?

Here's the slider code used for the site...

<?php 
$options = get_option( 'sample_theme_options' );

$slide_1_title = $options['sometext11'];
$slide_1_image = $options['sometext12'];
$slide_1_url = $options['sometext13'];
$slide_1_text = $options['sometextarea1'];

$slide_2_title = $options['sometext21'];
$slide_2_image = $options['sometext22'];
$slide_2_url = $options['sometext23'];
$slide_2_text = $options['sometextarea2'];

$slide_3_title = $options['sometext31'];
$slide_3_image = $options['sometext32'];
$slide_3_url = $options['sometext33'];
$slide_3_text = $options['sometextarea3'];

$slide_4_title = $options['sometext41'];
$slide_4_image = $options['sometext42'];
$slide_4_url = $options['sometext43'];
$slide_4_text = $options['sometextarea4'];

$slide_5_title = $options['sometext51'];
$slide_5_image = $options['sometext52'];
$slide_5_url = $options['sometext53'];
$slide_5_text = $options['sometextarea5'];
