Embedded videos from dailymotion

[dkarnout]

Dailymotion allows in some videos public view for embedded ones, or else returns HTTP error 404 Not Found.

For example I am able to view the embedded video of the following link:
http://greekdocumentaries1.blogspot.gr/2014/07/blog-post_26.html

I am also able to view the <iframe> of the embedded video:
http://www.dailymotion.com/embed/video/k81FJOfJK4ijDQ8iMKL

But get 404 error on this:
http://www.dailymotion.com/video/x211mo3

Is it possible for youtube-dl to capture the video from the link:
http://www.dailymotion.com/embed/video/k81FJOfJK4ijDQ8iMKL
instead of:
http://www.dailymotion.com/video/x211mo3

Thank you in advance.

The verbose result is:
