To expose the videoplayer you have to
Place a transparent layer directly over it
You can create a transparent layer by creating
A target rect with full transparent color above
the video player. It has to be at the
Same coordinates and the same size as
The destination rect of the player
To see any of your changes you need to
Refresh any changed layers by calling setlayer
Again. Your better off using roscreen
For what you are trying to accomplish
You are going to be disappointed in the
Performance with the imagecanvas
