40 * Function:  omxVCM4P2_MEGetBufSize   (6.2.4.1.1)
41 *
42 * Description:
43 * Computes the size, in bytes, of the vendor-specific specification
44 * structure for the following motion estimation functions:
45 * BlockMatch_Integer_8x8, BlockMatch_Integer_16x16, and MotionEstimationMB.
46 *
47 * Input Arguments:
48 *
49 *   MEmode - motion estimation mode; available modes are defined by the
50 *            enumerated type OMXVCM4P2MEMode
51 *   pMEParams - motion estimation parameters
52 *
53 * Output Arguments:
54 *
55 *   pSize - pointer to the number of bytes required for the specification
56 *            structure
57 *
58 * Return Value:
59 *
60 *    OMX_Sts_NoErr - no error
61 *    OMX_Sts_BadArgErr - one or more of the following is true:
62 *    -    an invalid value was specified for the parameter MEmode
63 *    -    a negative or zero value was specified for the
64 *         parameter pMEParams->searchRange
65 *
