160 /* * In case of planar formats, this ioctl allows up to 4 * buffer objects with offets and pitches per plane. * The pitch and offset order is dictated by the fourcc, * e.g. NV12 (http://fourcc.org/yuv.php#NV12) is described as: * * YUV 4:2:0 image with a plane of 8 bit Y samples * followed by an interleaved U/V plane containing * 8 bit 2x2 subsampled colour difference samples. * * So it would consist of Y as offset[0] and UV as * offeset[1]. Note that offset[0] will generally * be 0. */
