With NV12, NV21, NV16 and NV61 formats, the size of one pixel from the UV plane (plane #1) is one byte. Indeed, these pixel formats use 4:2:x chroma subsampling: the chroma pixels are sampled at half the luma: for 2 pixels, there are 1 Cb + 1 Cr = 2 bytes. So for plane #1, the correct size is actually 1 byte per pixel.
