Colorkeying with Xv and Intel Textured Video

[brentkowal at gmail.com]

Hello All,

I am working on an application which displays video using Xv and requires  
simple 2D annotation to be drawn on top of the video. In previous  
experience I've set the XV_COLORKEY parameter and was able to draw  
annotation on the destination window, and mask out of the annotation using  
the colorkey. This option is not available when I do an xvinfo. Is there a  
similar or alternative method of annotation video with the Intel Textured  
Video adapter?
