反交错和YUV422到420转换DM6446上使用的大小调整

Video signals captured directly from charge-coupled device (CCD) cameras naturallyhave interlaced effects and are in a 4:2:2 interleaved format. They typically need to beconverted to a 4:2:0 planar format before being encoded because most video compression standards accept input only in 4:2:0 format.
