/**
* Function: omxVCM4P10_MEInit (6.3.5.1.2)
*
* Description:
* Initializes the vendor-specific specification structure required for the
* omxVCM4P10 motion estimation functions: BlockMatch_Integer 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. The number of bytes required for the specification structure can
* be determined using the function omxVCM4P10_MEGetBufSize. 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
* searchRange16x16, searchRange8x8, etc.
*
* Input Arguments:
*
* MEmode - motion estimation mode; available modes are defined by the
* enumerated type OMXVCM4P10MEMode
* 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, if the function runs without error.
* OMX_Sts_BadArgErr - bad arguments: if one of the following cases occurs:
* - pMEParams or pSize is NULL.
* - an invalid value was specified for the parameter MEmode
* - a negative or zero value was specified for one of the search ranges
* (e.g., pMBParams >searchRange8x8, pMEParams->searchRange16x16, etc.)
* - either in isolation or in combination, one or more of the enables or
* search ranges in the structure *pMEParams were configured such
* that the requested behavior fails to comply with [ISO14496-10].
*
