/**
 * Function:  omxVCM4P2_MEGetBufSize   (6.2.4.1.1)
 *
 * Description:
 * Computes the size, in bytes, of the vendor-specific specification
 * structure for the following motion estimation functions:
 * BlockMatch_Integer_8x8, BlockMatch_Integer_16x16, and MotionEstimationMB.
 *
 * Input Arguments:
 *
 *   MEmode - motion estimation mode; available modes are defined by the
 *            enumerated type OMXVCM4P2MEMode
 *   pMEParams - motion estimation parameters
 *
 * Output Arguments:
 *
 *   pSize - pointer to the number of bytes required for the specification
 *            structure
 *
 * Return Value:
 *
 *    OMX_Sts_NoErr - no error
 *    OMX_Sts_BadArgErr - one or more of the following is true:
 *    -    an invalid value was specified for the parameter MEmode
 *    -    a negative or zero value was specified for the
 *         parameter pMEParams->searchRange
 *
