[x264-devel] [PATCH] fix waitkey work on the display window instead of exec console

[Limin Wang]

Hi,

When I try with x264 visual function, it's very difficult to
go to next frame for getchar() will focus on the exec console.
After the patch, you can press any key in your current desktop
to get the next display frame.

Thanks,
Limin
