I am using
XvShmPutImage to draw video via a YUV overlay into a window. Then I am
using XDraw commands to draw "overlays" directly to the window (lines, arcs,
text, etc.).
When I do this the
video image appears correctly, but the overlays do not update properly.

That
makes perfect sense. Is there a way to force the expose event at the
server without actually changing what is viewed (mapping/unmapping, moving,
etc)? I tried XSendEvent, but that didn't seem to
work.

One
more question - how can you tell what the chromakey value is? Do I need to
use XGetImage or is there a better way?

Most drivers implement XvShmPutImage as a video overlay. That
means it's not draw into the window. It was not the intention
that one should be able to render XvShmPutImage into a window along
with normal Xlib rendering, subsequently, that type of thing is not
supported in the general case.

Okay, the light bulb finally turned on!
I see that the chromakey is something I can set via XvSetPortAttribute(). I
also see what you mean about not directly putting the image and drawing the
data to the window.
The following sequence seems to be working well:
For each video frame:
