Check out the CVS code for smpeg:

The YV12 format is probably what you want - it has the lum plane followed
by the Cr and Cb (chrominance) planes.  Create an SDL YUV overlay with
the SDL_YV12_OVERLAY format and decode directly to those pixels.

Then call SDL_DisplayYUVOverlay() to display it on the screen.

See ya!
