i don't understand this. why are reads unaligned?
i think width/height values are only used to limit loops.

stride is %16==0 (16, because UV stride is stride>>1 so it's %8==0 now)

or do you mean the source image stride? it should be 16-aligned too as
ffmpeg uses 16x16 blocks and +2*32 wide UMC area internally.
