Direct link to video in Google Plus

You can use the Google+ Share Link

The share link is intended for native client applications, Flash applications, highly privacy-sensitive sites, and others who may not be able to use the +1 or share button. Adding the following markup to your site will include a simple icon which will pop open a share dialog for your visitors.

<a href="https://plus.google.com/share?url={URL}" onclick="javascript:window.open(this.href,'', 'menubar=no,toolbar=no,resizable=yes,scrollbars=yes,height=600,width=600');return false;"><img src="https://www.gstatic.com/images/icons/gplus-64.png" alt="Share on Google+"/></a>

Note: Replace {URL} with the URL of the page you want to share. You must properly escape any user-generated content that may occur within {URL}

If you just want a raw link, you can just use

https://plus.google.com/share?url={URL}

Just make sure you properly escape the "{URL}" value.

The only other thing you can add besides the URL to share is the language code for the language to be used on the share page.

You can go to picasaweb and make it from there, but you must use special url https://picasaweb.google.com/lh/myphotos?noredirect=1
