But MPlayer doesn't receive the move event of the external window. So
you must poll all the time to check for external window position.

The callback function resides in the external application. That's why
you have to poll for the movement of that window. Try it and see.
Geometry is needed because the way vo_directx works right now is this:
1. Create a window with width and height according to video params.
2. From now on, always use window size to size video.
So, what happens with an external window is that the video is stretched
to the size of the window, which is not always a good thing. So my
patch changes it so that the SetWindowPosition calls don't happen if
we're using an external window.
I'll start a new thread about this. In any case, borderless option is
fine. It's just not the best thing for embedding MPlayer in another
app. Go ahead and commit.
