/**
 * 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 
 *
