I see some confusion going on here.. There are two different StopVideo
functions: one inside the driver and one in Xv library. The
library function instructs X to call StopVideo function in the driver, but
the latter can also be called by Xserver without request. For example, if
you open a window and make a single PutImage or PutVideo call and then
destroy the window Xserver will call StopVideo in the driver even though
you did not make StopVideo call through Xv library.
Does this help ?
