There is a way to request larger thumbnails for @koko-ng method by adding in additional arguments to the oembed request. It definitely works with vimeo, not sure about Youtube though.

function get_video_thumbnail_uri( $video_uri, $max_width = 960, $max_height = 540 ) {
	$thumbnail_uri = '';
	
	//get wp_oEmed object, not a public method. new WP_oEmbed() would also be possible
	$oembed = new WP_oEmbed();
	//get provider
	$provider = $oembed->get_provider($video_uri);
	//fetch oembed data as an object
	$oembed_data = $oembed->fetch( $provider, $video_uri, array( 'width' => $max_width, 'height' => $max_height ) );
	//print_r($oembed_data);
	$thumbnail_uri = $oembed_data->thumbnail_url;	

	// get default/placeholder thumbnail
	if( empty( $thumbnail_uri ) || is_wp_error( $thumbnail_uri ) ){
		$thumbnail_uri = ''; 
	}

	//return thumbnail uri
	return $thumbnail_uri;
}
