Youtube api v3 Get list of user's videos

With Youtube api v2, there's easy way to get videos. Just send a query like this:

http://gdata.youtube.com/feeds/mobile/videos?max-results=5&alt=rss&orderby=published&author=OneDirectionVEVO

The Youtube api v2 also has an interactive demo page for building query:http://gdata.youtube.com/demo/index.html

With Youtube api v3, I don't know the corresponding way. Please point me the way with api v3.

Thank you!
