YVU420PackedSemiPlanar32m4ka与YUV420PackedSemiPlanar64x32Tile2m8ka

YVU420PackedSemiPlanar32m4ka与YUV420PackedSemiPlanar64x32Tile2m8ka都是nv12变换来的。

*  YVU420PackedSemiPlanar       : Buffer containing all Y, and then V and U 

 *                                 interleaved.

 *  YVU420PackedSemiPlanar32m4ka : YUV planar format, similar to the 

 *                                 YVU420PackedSemiPlanar format, but with the

 *                                 following restrictions:

 *

 *                                 1. The width and height of both plane must 

 *                                 be a multiple of 32 texels.

 *

 *                                 2. The base address of both planes must be 

 *                                 aligned to a 4kB boundary.
