Use in Custom Fields

I’ve got the same question here. I want to use this plugin with the detube theme, but for this theme a custom field is used where the youtube link should be entered. Should this also work using this plugin with a small change in the coding of this plugin?

You need to apply filters

$meta = get_post_meta(get_the_ID(), 'video', true);
                $content = apply_filters('the_content', $meta);
                echo $content;
