Ideally you should use the method recommended by DOCS/tech/libvo.txt:
Implement VOCTRL_UPDATE_SCREENINFO and then use vo_dx, vo_dy, vo_dwidth
and vo_height directly.
Also you should at least clamp the values so that you don't end up
writing outside the frame buffer, I expect your patch will crash
reliably with e.g.
-geometry 0:10000
or
-geometry 0:-900
or
-geometry 800:10000
...
