How do I create slideshows for Youtube videos?
Follow these steps


Install and enable these four modules:[

CTools
 Views
 Views Slideshow
 Libraries


You're also going to need a single file that contains a JQuery slideshow script. This will need to be uploaded manually.

Visit link
Click the Download the Cycle Plugin link. It's hard to spot so i had highlighted it on the image below:



Download the file which will be called jquery.cycle.all.js
Access your site files.
Browse to the /sites/all/ folder.
Create a folder called /libraries/ so that the path is /sites/all/libraries/
Create a folder called /jquery.cycle/ so that the path is /sites/all/libraries//jquery.cycle/
Upload the jquery.cycle.all.js file into that last folder.



Step 2: Views

We're going to create our slideshow using Views.

Go to Structure > Views > Add new view.
Check Create a block
Choose Slideshow for the Display format
Choose 1 for the Items per page

Click Add.
Select video.
Click Apply (All displays).

Check the box which says Exclude from display.
Click Apply (All displays).

Find the Format area on the left-hand side of the Views page.
Click Settings next to Slideshow.

Scroll down to the cycle options.
Click Apply (All displays).
