Fix for WordPress 4.4.2 for YouTube Video Error

Hello, My name is Marc Tanne. My co-developer and I have used this plugin and developed a fix for the YouTube error. In essence, WP 4.4 changed the way the src was structured. Please replace the code specified below in your class-oembed.php file located under:

SiteName/wp-content/plugins/featured-video-plus/php/class-oembed.php

where it says public function get_html{} delete this entire function and place the code below in it’s place:

public function get_html( $url, $args = array(), $provider = null ) {
		if ( $provider ) {
			$args = $this->filter_legal_args( $provider, $args );
		}

		$html = $this->oembed->get_html( $url, $args );

		if ( empty( $provider ) ) {
			return $html;
		}

		// Some providers do not provide it's player API to oEmbed requests,
		// therefore the plugin needs to manually interfere with their iframe's
		// source URL..
		switch ( $provider ) {

			// YouTube.com
			case 'youtube':
				// Add <code>origin</code> paramter.
				$args['origin'] = urlencode( get_bloginfo( 'url' ) );

				// The loop parameter does not work with single videos if there is no
				// playlist defined. Workaround: Set playlist to video itself.
				// @see https://developers.google.com/youtube/player_parameters#loop-supported-players
				if ( ! empty( $args['loop'] ) && $args['loop'] ) {
					$args['playlist'] = $this->get_youtube_video_id( $url );
				}

				// Remove fullscreen button manually because the YouTube API
				//  does not care about <code>&fs=0</code>.
				if ( array_key_exists( 'fs', $args ) && $args['fs'] == 0 ) {
					$html = str_replace( 'allowfullscreen', '', $html );
				}

				// We strip the 'feature=oembed' from the parameters because it breaks
				// some parameters.
				$hook = '?feature=oembed';
				$html = str_replace( $hook, '', $html );
				break;

			// DailyMotion.com
			case 'dailymotion':
				$args = $this->translate_time_arg( $args );
				break;
		}

		if ( ! empty( $args ) ) {
			$pattern = "/src=([\"'])([^\"']*)[\"']/";
			preg_match( $pattern, $html, $match );
			if ( ! empty( $match[1] ) && ! empty( $match[2] ) ) {
				$code = $this->clean_wp_embed($match[2]);
				$replace = sprintf('src=$1%s$1', add_query_arg( $args, $code ) );
				$html = preg_replace( $pattern, $replace, $html );
			}
		}

		return $html;
	}

	public function clean_wp_embed($url)
	{
		$out = $url;

		$out = preg_replace("/\?/","&",$out,1);
		$out = preg_replace("/&/","?",$out,1);

		return $out;
	}
