Create a playlist of Offline videos in YouTube YouTube's offline feature allows downloading selected videos so that they can be viewed later, without internet.

I downloaded few of these from different publishers and now have set of such videos in my device. 

However, I could not find an option to create a playlist of these downloaded videos through YouTube app.

My intention is to create my own playlist from the set of downloaded videos.

Is this possible?
I suggest you download tubemate app. This downloads youtube videos to your device. Then,  you can easily make Playlist from downloaded videos.
