WordPress pull images and video shortcodes from post using regex

Hoping someone can help me out with this. I’m already pulling images from wordpress posts using a regex. Can’t figure out how to pull both video and images though. Sorry I suck at regex. Here’s the code I’m using:

 <?php
    $PostContent = $post->post_content;
    $SearchPattern = '~<img [^>]* />~';

// Run preg_match_all to grab all the images and save the results in $aPics
    preg_match_all( $SearchPattern, $PostContent, $allPics );

// Check to see if we have at least 1 image
    $iNumberOfPics = count($allPics[0]);

    if ( $iNumberOfPics > 0 ) {
        // Now here you would do whatever you need to do with the images
        // For this example the images are just displayed
        for ( $i=0; $i < $iNumberOfPics ; $i++ ) {
            echo '<li>' . $allPics[0][$i] . '</li>';
        };
    };
?>

Any Idea how to edit the searchpattern to also pull wordpress video embeds from the post content like this:

Appreciate any advice. – Sean
