您可以使用快捷码控制嵌入式TED视频的大小：

[ted id="1650" width="300" height="200"]

if(!isset($atts[\'width\'])){
    $atts[\'width\']=600; // Default width
}
if(!isset($atts[\'height\'])){
    $atts[\'height\']=400; // Default height
}

// Whitelist the TEDTalks oEmbed URL
wp_oembed_add_provider( \'http://www.ted.com/talks/*\', \'http://www.ted.com/talks/oembed.json\' );

function ted_shortcode( $atts ) {
    // We need to use the WP_Embed class instance
    global $wp_embed;

    // width:
    if(!isset($atts[\'width\'])){
     $atts[\'width\']=600; // Default width
    }  

    // height:
    if(!isset($atts[\'height\'])){
     $atts[\'height\']=400; // Default height
    }

    // The "id" parameter is required
    if ( empty($atts[\'id\']) )
        return \'\';

    // Construct the TEDTalk URL
    $url = \'http://www.ted.com/talks/view/lang/eng/id/\' . $atts[\'id\'];

    // Run the URL through the  handler.
    // This handler handles calling the oEmbed class
    // and more importantly will also do the caching!
    return $wp_embed->shortcode( $atts, $url );
}
add_shortcode( \'ted\', \'ted_shortcode\' );
