Default YouTube Embeds size is wrong on all device widths

[andrebu]

The static width and height in pixels set by the native embed function messes up the size of all YT Embed videos.

One proposed but untried solution is to use a function in function.php:

add_filter( 'embed_defaults', 'change_embed_size' );

function change_embed_size() {
    // Adjust values
    return array('width' => 100, 'height' => 100);
}
