How to allocate surfaces for YUV image?

Hi All,

I want to display a planar YUV image on a RGB display device. So I allocate three surfaces for the layer and want to 
know how to configure the context of each surface and show the image, can anyone provide a demo code or some 
sugguestions?

Thanks,
Ray

As the user guide described,"Planar YUV is a video display format. The GF library doesn't support rendering to planar 
YUV; however, you can display planar YUV data that's already been rendered by another application." is it available to 
display an yuv image directly?

It's probably easier to integrate a SDL window with YUV support.

Re: How to allocate surfaces for YUV image?

are we able to allocate 3 surfaces for YUV and display it on the layer without the SDL framework? I don't want to make 
it complex..
