If you don't want to do this programmatically you can use VideoGallery control
1. Drop the control on a page
2. Open the control for editing
3. Set Sort videos
4.Go to Settings
and set Use Limit
Note that this control does not support autoplay.
If you want to show the last item and use AutoPlay, you have to create a custom control that inherits from MediaPlayerControl. The control has a property MediaUrl which you can set to the last uploaded item. To get the last uploaded item you can use the Media Modules API
