How to open native youtube app from a video embedded in web page when I view a page on my iPad and there is a YouTube video embedded, if I click it I can watch it directly within safari.
This way, though, I cannot favorite the video, I cannot know the title of it or share it. Only thing I can do is watch it.

I'd like to be able to open the link to video in native youtube app, or at least open the YouTube web page of that video.

Is there a way to do it?
The following applies to IOS 8 on iPhone:
A YouTube logo appears in the lower right corner of embedded YouTube videos. 

If you click on the usual big round 'play button' in the center of the embedded video, it will play fullscreen inside Safari. However if you click on the YouTube logo, the video will open in the YouTube app.
