roVideoPlayer/roImageCanvas together?

want to first start out by saying thank you for any help for a noobie....

I am searching thru the docs and forum but cant find how to do or examples of this:

roVideoPlayer – allows you play a video in a region on the screen and/or programmatically control playback. When used in conjunction with roImageCanvas, you can combine video, images and text on a single screen.

I have been going thru the channel guides as well and don't see these. so are there examples of anyone doing this or documentation on how to do it?

thanks i am hoping to have my first creation ready soon!
