Stretching yuv (YUY2) problem

Stretching yuv (YUY2) problem

Post by eric » Sat, 18 Sep 2004 06:00:52


I blit a yuy2 offscreen surface on the primary surface while doing a
shrink.
It works fine, until I shrink too much.

Is there a stretching limit or something i'm doing wrong?

please see the comparision screenshot. The source image was 640x480.
Top image is correct, bottom is not.

The problem is not there when using only RGB surfaces.
I have a Radeon 7000.

Thanks,
