CVPixelBufferCreateWithBytes & YCbCr

Hi,

I have been trying to use the new API CVPixelBufferCreateWithBytes() to create a CVImageBuffer from some data in k2vuyPixelFormat. Unfortunately the API is not working as advertised for me.
If I use the correct parameters for width, height and rowbytes, then I get a misaligned image, but If I leave rowBytes the same and halve the width, then an image half the width is correctly created (logically, this should not happen).

I have played with various values of rowbytes and width, to no avail. The
Has anyone tried this successfully? Any known bugs?

Thx
Gabe
