YUV There are two types of formats : Plane (planar) And compact (packed).
about planar Of YUV Format , First, store all pixels in a row Y, And then it stores all the pixels U, And then all the pixels V.
about packed Of YUV Format , Every pixel point Y,U,V It's continuous * Stored . The following abbreviations p Express “ compact ”,sp Express “ Semi compact ”.
With resolution 8*4 For example , The data storage method is as follows .
