     25  * Function:  omxVCM4P2_MEGetBufSize   (6.2.4.1.1)
     26  *
     27  * Description:
     28  * Computes the size, in bytes, of the vendor-specific specification
     29  * structure for the following motion estimation functions:
     30  * BlockMatch_Integer_8x8, BlockMatch_Integer_16x16, and MotionEstimationMB.
     31  *
     32  * Input Arguments:
     33  *
     34  *   MEmode - motion estimation mode; available modes are defined by the
     35  *            enumerated type OMXVCM4P2MEMode
     36  *   pMEParams - motion estimation parameters
     37  *
     38  * Output Arguments:
     39  *
     40  *   pSize - pointer to the number of bytes required for the specification
     41  *            structure
     42  *
     43  * Return Value:
     44  *
     45  *    OMX_Sts_NoErr - no error
     46  *    OMX_Sts_BadArgErr - one or more of the following is true:
     47  *    -    an invalid value was specified for the parameter MEmode
     48  *    -    a negative or zero value was specified for the
     49  *         parameter pMEParams->searchRange
     50  *
