/**
* 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
*
