Yes, possible. Up to now, I'm sure v4l ReadThread keeps outputing frames,
but I didn't find any related Blt for video preview window, only Blt for
the video of my friends. And there's so many surfaces QQ created, I can
only guess which surface is for preview and remote video from the surface's
DSCAPS and DS_WIDTH/HEIGHT, I didn't find any surface close to
preview video's width and height.

Now since my timestamp modification finally doesn't solve QQ problem,
I'm now checking whether something wrong with ddraw/d3d7.
