I want to know some information about YV12 image format.
1st question is YV12 Image format is equal to YUV420p format or YVU420p or YUV420Sp or YVU420Sp. I know that U and V have the same amount of memory in the format so in the case of planer image formats does swapping U and V makes some major difference. and if it does can some body explain me what is that.
Also i have heard that YV12 and NV12 are both 12 bits formats. Then can some body tell me that what is 4:2:0? it will be great if some can explain me in simple words thanks
