Integration in theme.

Hi Im writing a function where Im adding several plugins compatibility in the theme using the tgm.

for the jwplayer Im trying to add something like this:

if ( shortcode_exists( 'jwplayer' ) ) {
		$shortcode = '[jwplayer file="'.$get_video.'"]';
	} elseif( shortcode_exists( 'KGVID' ) ){
		$options = get_option('kgvid_video_embed_options');
		$shortcode = '
			[KGVID
				poster="'.$thumb.'"
				height="'.$options['height'].'"
				width="'.$options['width'].'"
				autoplay=""
			]
				'.$get_video.'
			[/KGVID]
		';
	} else {

But I dont see the jwplayer there is only KGVID is there any specific code or more details about your plugin, How can I call your plugin settings and I want to make it able to get also the poster not only the file which one is described here.
