YUVPThis is another format similar to YUY2 and it's aliases. The difference here is that each Y, U and V samples is 10 bits rather than 8. I am still waiting to hear how the samples are packed - is a macropixel just 5 bytes long with all the samples packed together or is there more to it than this?yuv420 应该是 每 4 个点只取一个 U, 每 4 个只点取一个 v, (和 u 不同位置) 每个点都取 Y YU Y YU Y ...... YV Y YV Y ...... YU Y YU Y ......
