Sharing custom video player in Google Plus' Stream

Does anyone know how to embed a custom video player into the Google Plus' Stream?

You can share videos by uploading, via YouTube, or from your phone, but you can also embed the Vimeo player into the stream, for instance, by just dropping the Vimeo video's URL into the Stream.

I assume Google is parsing the markup of the URL for specific meta so that it can render it as a video, much like you can do with Facebook's Open Graph:

Is there a similar way to do the same with Google Plus?

Thanks!

You should try using schema.org markup instead: http://schema.org/VideoObject
