You want to dump video from a capture card into the overlay?
Is this a Video4Linux device? The V4L module in the X-server should
already be able to do that for you. Basically, the functions
for setting up an overlay surface are only internal to the X-server,
so another X-server module is the only thing that can arrange
to have an overlay surface set up.
