+/**
+ * Function:  omxVCM4P2_MEInit   (6.2.4.1.2)
+ *
+ * Description:
+ * Initializes the vendor-specific specification structure required for the 
+ * following motion estimation functions:  BlockMatch_Integer_8x8, 
+ * BlockMatch_Integer_16x16, and MotionEstimationMB. Memory for the 
+ * specification structure *pMESpec must be allocated prior to calling the 
+ * function, and should be aligned on a 4-byte boundary.  Following 
+ * initialization by this function, the vendor-specific structure *pMESpec 
+ * should contain an implementation-specific representation of all motion 
+ * estimation parameters received via the structure pMEParams, for example  
+ * rndVal, searchRange, etc.  The number of bytes required for the 
+ * specification structure can be determined using the function 
+ * omxVCM4P2_MEGetBufSize. 
+ *
+ * Input Arguments:
+ *   
+ *   MEmode - motion estimation mode; available modes are defined by the 
+ *            enumerated type OMXVCM4P2MEMode 
+ *   pMEParams - motion estimation parameters 
+ *   pMESpec - pointer to the uninitialized ME specification structure 
+ *
+ * Output Arguments:
+ *   
+ *   pMESpec - pointer to the initialized ME 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 
+ *
