It depends on usage of XWarpPointer(3X11) function. If you set src_w
to None the mouse pointer could be anywhere on the screen and it will
work. I found it more usable to activate this hack only if mouse
pointer is inside mplayer window but of course it is not mandatory.

Focus setting has nothing to do here. If I use XWarpPointer(dpy, None,
None, 0, 0, 0, 0, mx, 0) for example and mx = 16 then mx = -mx in a
loop it works always not depending on which window is focused, which is
on top or mapped.

If we detect mouse movement different from desired or other mouse event
(any other then moving) or key event we could first switch off fake
mouse movements and then just serve the event. From my point of view
if could be done together with mouse pointer hidding/unhidding function.
Generally I see no problem here.

It works IMHO and it's worth to try this solution.
