Use U and V textures and corresponding dma buffers that match the size of the input UV data rather than using textures and DMA buffers that match the Y data. This simplifies data copy and reduces the amount of image data transfered to the host by up to 50% (YV12). It also reduces dma buffer- and surface memory usage correspondingly.
