I'm not sure what this will work faster than if i packed in to YUV422 on C and sended by DMA complete texture
It turns out that the conversion YUV420p to YUV422 simpler than the division into macro blocks, and sends by one request to the DMA, in contrast to the converter...

Re: PVR YUV->UYVY Conversion
Yeah, I was bummed out when I got this far, to find out its really not much faster to do this way.SWAT wrote:I'm not sure what this will work faster than if i packed in to YUV422 on C and sended by DMA complete texture

Maybe the best thing we can do is optimize the YUV420p to YUV422 packing in SH4 ASM?
