I’m trying to display a dynamic overlay image (an image translated in a pseudo-random and variant way) over a video stream using Java API so I developed a module to attach to an application. I was looking at this tutorial:

[http://community.wowza.com/community/questions/ask.html?space=24](http://community.wowza.com/community/questions/ask.html?space=24)

There, an OverlayImage class is used but this class doesn’t appear in Java API (IDE WOWA v.4). How can I do it without using OverlayImage?

Can you correct the link to the tutorial you followed @ERL ERL? Was it this one?

Sorry, the tutorial I was referring to was that one.
