Adding nosnippet attributes to video embeds

Hi,

I have noticed that Google is displaying “Uploaded by” in the SERPs for pages in which I’ve embedded a video. I want them to display the post publish date, not the date of an embedded video. To accomplish this, I need to add:

data-nosnippet=”true”

to surround the div of my video embeds. Is there any way I can implement this as a global (site-wide) rule and not have to modify the HTML of every video embed on my site?

If this is the wrong forum for this, let me know where I should go.

Thanks
