WebYUYV is YUV 4:2:2, a weird term that says: "for a HxW image, Y is saved at full res, U and V are downsampled horizontally, and the bytes of UINT8 are stored in this order YUYVYUYVYUYV...". So it is in fact a 3 channel image, but 1 channel is bigger. So you can consider it's a 2 channel images: Y, and UV that are stored in an interleaved fashion.
