You could use the {capture} function to capture the output into a variable, then choose what to do with it:

{capture name="video_meta"}{get_video_meta video_id=$video_data.id key='test'}{/capture}
{if empty($smarty.capture.video_meta)}
 No value
 {else}
 {$smarty.capture.video_meta}
{/if}

You can assign value to variable:

{if empty($code)}
    {assign var='code' value='404'}
{/if}

but i suppose that you need something like:

{if empty($video_data.id)}
    No value
{else}
    {get_video_meta video_id=$video_data.id key='test'}
{/if}

because get_video_meta - it's smarty plugin, and you can't use it like you try to use...

In foreach:

{foreach from=$video_data key=k item=v}
    {if empty($k)}
        No value
    {else}
        {get_video_meta video_id=$v.id key=$k}
    {/if}
{/foreach}
