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?
