How to add videos on my home page slider?

Question

How would you recommend adding videos to my website's home page slideshow, here is the php code that creates the slideshow:

<?php global $gpp; ?> 
<div class="app">
<div id="slideshow">
<?php
 $slides = array('gpp_slideshow_image_1','gpp_slideshow_image_2','gpp_slideshow_image_3');
 $i=0;
    foreach ($slides as $slide) {
        if($gpp[$slide]<>"") {
            echo '<div class="slide"><img alt="'.get_bloginfo('name').'" src="'.$gpp[$slide].'" /></div>',"\n";
        }
    }
?>
</div>
</div>

From the GPP Slideshow description:

The GPP Slideshow plugin for WordPress allows you to create minimalist image slideshows...

This plugin is built to only handle image slideshows, so I seriously doubt it could easily handle non-image content such as videos. You're much better off moving on to a slideshow that is built to handle multiple types of media. (Sidenote: And if that's the slideshow code then it's rather inaccessible anyway and you're better off moving on for that reason alone.)

As a rule I don't like slideshows so I don't use them much, but some plugins that might be better-suited to your task are AnythingSlider (might be abandoned, though, so proceed at your own risk) or one that uses FlexSlider 2.
