Wow, current ffplay code assumes that no keypress or mouse events will 
come before the window is shown. Strange thing that SDL2 on IOS 
is forwarding input events even without a window...

So in order to fix this more thoroughly, I suggest the attached patch 
instead. Supporting keypresses without a window (e.g. -nodisp mode) might 
be possible, but that requires bigger changes...
